I have a couple boxs of 30cal 190 accubonds
And a whole bunch of social distancing time

What powder should I use for my invention
I tried r17 and got good velocity but erratic accuracy


In the cupboard on hand I have
R19
Big Game
V550
R17
Varget

I have a 20" barrel, shoots 1/2-3/4" groups w hornady factory ammo

A 20" 6.5 shoots 140g at 2600fps or so

Looking for that or faster w the 190's

What do you think?

Do you mean 180 grain? If so, I'm a fan of Superformance. However it's not one you listed. Of those, I'd try Varget next.

"30-06 creedmore"

Good God, man! Saddling the great 30-06 with that label is like making Sophia Loren twerk.

I load 190 gr. Hornady BTSP (discontinued) with H4350 and am pushing 2800. R-17 or V-550 ought to get you past 2600 without a problem.

A burn rate approximating the 4350s should be right for a 180-190 grain bullet in the 30-06. So, RL-17 is the place I would start. I'm getting over 2,750 fps in my Bergara 30-06 with 24" barrel shooting 180 grain Partitions over 56 grains of H 4350. Pressure is below max, and accuracy is excellent.

LOL, would you watch??

Is there a powder called "Pink Dot"?

I think you are in to something

Twerk? This is a sex change. An abomination from a sick mind mired in filth.

what the hell is your invention, you never described it. Also, if you invented(I use the term loosly) a .30 cal. Crudmoor,You don't need to call it .30-06 Crudmoor, just call it .30 Crudmoor. I agree with Theo Gallus. Don't saddle the venerable .30-06 with such slander as that. Next thing you'll be telling us you invented a .270 Crudmoor, then I'd be pissed for sure, LOL!!!

I'm thinking alcohol was involved in the making of this thread...

As to the 190 LRAB, I'd stick with RL17. I'd start with a below max charge and work up. I'd play around with seating depths.

Also, it wouldn't surprise me if ultimately your particular 30-06 just doesn't like the 190 LRAB...

Seriously, all jokes aside, I've used RL,-17 a lot in smaller cases with great results. But I don't think it's quite the same as 4350. When it first came out it was described to me that you could pretty safely use 4350 data to begin working up a load, but things changed somewhat as you went along.

For one thing, I've heard that it is somewhat in the league with Superformance Powders in that It is not like most powders because it contains its inhibitors within the powder formula and not just dusted on the outside of the grains as in most powders. I was told this contributes to a slower pressure curve and it has less of a pressure peak. This is what I've been told. I'm no chemist and you can take all this with a grain of salt and do your own research. I called Alliant and spoke with a customer service rep and told him what I had been told. He wouldn't deny any of it but thanked me for the info.

However, upon the advice of a friend who had used it in his 6mm Remington with great results, I worked up a load with it for my .250 Savage. I got tremendous results with really great velocities with no visible signs of pressure. Also note that this was with 115 grain bullets, not 100s. However I did find that I was a bit over pressure when I went to reprime the cases and found that this load had loosened the primer pockets. At that powder charge it was expanding the case heads.

I destroyed those cases and loaded new ones dropping the charge a couple grains lower. Then worked it up again slowly (This took around six months because I was being very cautious and also it was a wet year and I couldn't always get to my range when it rained too much.). I got it up to 1 grain less than before with no signs of pressure and no problem with primer pocket expansion and called that good. I found I still got fantastic velocity and good accuracy with no signs of excessive pressure and the primer pockets didn't expand noticeably. That was good enough for me.

For safety sake I won't list my powder charge or velocity here in case my results are a fluke, because I have a 26" barrel and my chamber has a long throat. It's on a Howa 1500 action which I believe has a longer Magazine than a Remington short action so I have more room to seat bullets longer which gives me more powder capacity without excessive pressure. I'll just say it puts the already excellent little .250 Savage in a bit higher class even with the heavier bullets.

Those are my results with RL-17 in a .250 Savage and I had reasonably good results wth it in my .257 AI but I don't know how well it works in longer, higher capacity cases such as a .270 or .06. Proceed at your own risk, LOL!

Filman, I've used RL17 to good effect in the 6.5 CM, 7-08, 270, and 300 WSM.

My opinion is, like RL26 and Big Game, many run RL17 powder too "hard."

In the 300 WSM for instance, my "go-to" load was 64.0 H4350 with a 180 @ 2,980 fps. I found that RL17 was at its best with 64.5 gr's with a 180 for 3,030 fps. One can go a bit highert higher, but I felt beyond 65.0 was over-pressure.

Basically, I think you can add .08% +/- to your book H4350 load to arrive at a viable, sane RL17 load.

Sorry to slander the 30-06

We have a 3% infection rate in my town BTW, maybe that effected my judgement

Anyway....

I am shooting a browning BOSS,
So I build a load then adjust the BOSS, I use a suppressor instead of the weight

With the best BOSS settings I will get 2-3 that group cloverleaf then a flier 2”-3” out
Then I adjust the BOSS again
This is w R17

They are indeed 190g LRAB bullets

Wondering if the Rifle doesn’t like the bullet
Or if the R17 is causing the unpredictable fliers
OAL is 3.37

The Nosler loading site is showing 54.5 grs. of R17 with their 190 LRAB for about 2750 fps from a 24" barrel. So you might get 2600+fps outa the 20" barrel.

I am getting plenty of velocity, North of 2700fps

Just wondering why 2-3 touching; then one in left field

It’s not the rifle

Thanks for the reply to my post Brad, that's good to know. I don't think RL-17 will do what it did in my .250 in many other cartridges. For instance, it didn't have quite the same effect in my .257 AI. It did good but nothing spectacular. But in my friend's 6mm and my .250 it was sort of over and beyond without the excess pressure.

.................Yep! A 6.5 Creed necked up to a 30 cal.......To the OP. Invention? Well go for it since you now have a lot of time on your hands.

Similar to the 308 a little? Have fun.

Wouldn’t it be the .30 Thompson Center?

What about RL-16? Just for the fact that it's more temp stable and possibly less erratic? Is it too far away from RL-17 as far as burn rate?

Kellyweek,

You nailed it with, "Wouldn’t it be the .30 Thompson Center?"

Which is also basically the .300 Savage.

I thought it was the savage with just a little taper removed but wasn't sure.

MtnT

30-06 'creedmoor'

GAG,

HORROR,

Your sir are now OFF the Christmas list !



Yeah, I read your Xcuse..... don't let it happen again !

Jerry

I always used reloader 22 with heavy bullets in the 30-06

Well, no, but if it was the "younger Sophia", I would be tempted. The older, I would be repulsed! lol

I loaded and fired over 2500 round of 30-06. tried a lot of load none were any better than this.

Now that’s good to know.......

Lapua 185 Mega was hard on hogs in my 18" barreled gov't. Slow as a 45/70 but quite effective.

Mix Red Dot in a 50/50 mix with milk, let it dry... and I think you'd have Pink Dot...

Well, I am sure that the 30-06 participated in several Creedmoor matches over the years.

Does misspelling it make it any better? Or worse?
Actually though I think it's a very valid idea. The '06 ought (no pun intended) to be able to match the Creedmoor trajectory wise. And bring a lot more whomp when it gets there.
Now I'll go back and read the rest of the thread...

300 savage wtf? Every other thread here praises it to the skies and you guys all of a sudden act like your gonna ralf all over your shoes.jfc get a life. MB

I have also been playing around with my pre 64 30-06 and 190 ABLR. The rifle shoots 180 ABs at 2780 FPS into 3/4" groups, but wanted to see if I could stretch it out.

Powders I have are RL17, RL16, H4350, Hunter, and RL26.

I am not finished testing, but the best so far was the only load I tried with RL17. 54.5g at 3.350". 2 touching and a 1" flyer. I don't have velocities in front of me, but believe it was right around 2,700 FPS.

Hunter shot very similar groups and velocities to RL17. I tried 58.0 and 59.0g.

I wanted RL16 to work because it is more temp stable than RL17, but only group I tried with 55.5g was about 2", so probably won't mess with it much more.

RL26 has potential. A little bigger groups than RL17 or Hunter (around 1.5"), but velocity is around 2,800 FPS with 62.0g and no visual pressure signs, but probably about max that I will go. I will play with seating depth some more on this.

OK, Bonepoint is ahead of me

I cant spell, and I am not terrible bright

here is why: I keep reading articles that I don't get on how the 6.5cm is superior to the '06 at long range

here is the story problem: of the '06 shoots a 190g faster than a 143g 6.5 from the same barrel length and the bullets have the same BC and your using a suppressor that softens the recoil so that doesn't matter

the rifle is for hunting Elk, what is the advantage of the 6.5 again?, that is where I get lost

the only fly in the ointment is I need to get my flyers under control
2-3 touching - flyer, 2-3 touching - flyer

is it the bullet is to heavy for the twist rate? the powder? seating depth?

once we crack that code the 30-06 CM will be the undisputed king, it might have been already w/o CM

You didn't say what velocities you were achieving from the .308. but I'd stay with the Rel 17 and drop the charges a grain or so and work on the seating depth. 2 together and 3rd apart means the OAl is too long. Large equilateral triangles means it is too short. Apply minor adjustments to the seating die of around 1/8th turn. The more slim the barrel, the turns are less and the results much more. I have recorded dramatic results with even 1mm (..040") turns in very light barrels.

The 6.5 CM kicks a lot less. For most of us that translates into more, and more precise shooting. And a 6.5 CM can be built lighter, but still be comfortable to shoot. In the mountains that's a nice trait.

I'd also wager a 6.5mm/140 of equal construction to a .308/190 will equal (and perhaps exceed) the 190's penetration.

At the end of the day, a precisely placed shot with ample expansion and penetration trumps "energy" figures...

Only thing that makes any sense on this thread!!

ok, we are down to Vodka & Tang here at lockdown, our mayor has the C19

I looked at my notes from last year
my best group was 4 shots. 55g R17, 3.38oal QL calc'd pressure 58k, 2783, 2793, 2796, 2798, 1/4" group
with the browning BOSS set at 8.5. never to be repeated again LOL, 1 1/2"-2" after that, 2 together, one flyer


see the tease?

I can try OAL 3.36? 3.34? per AussieGunWritter, I already have 40 loaded, I will just crimp them down 0.02-0.04

lets change the name to 30-06 PRC lite

Aussie, should I give that a shot?

I just checked my batch of 40

I am at 3.363-3.365 OAL ave

bring them down to 3.40?

No, too much reduction.

I reviewed 4 or 5 different rifles when the BOSS Unit was released and found with the Browning in particular, with its very light barrels, some charges were slight barely turning the Boss unit which is why I stated 1mm or .040" as a measure point.

That was not an OAL adjustment, it was meant to be a die movement which will be less in OAL as an adjustment. I have a Model 70 Featherweight in 7x57 which made obvious gains with only .003 taken off the OAL.

You are in a position to take your loads to the range with your press and seating die set up and drop them 2-4 thou per group. You will be pleased.
