Home Forums Hunting & Shooting Ask The Gunwriters 06/200 @ 2700 question

Great thread, I have a 24" '06 comming my way and now I'm thinking about 200gr Gamekings, Accubonds and Partitions....

I loaded 59 grains of old H-4831 behind a 200 Partition for 2700 FPS back in the 80's. That load was not hard on brass at all. I do want to hear how the 63.5 grain load goes for you

I'm having fun with the last two range trips. But unlike SU35, I'm not starting over the manual and proceeding, but under it and progressing. Easy there SU35, I'd have to drag out my old "Second Chance Vest" and a full face shield if I went to the range with you!

I hope no one here really wants to redline a 200/30-06 cause if you do, Bobinnh has the solution. But I don't want to go there. I just want something a little edgy than a 180gr. in a 30-06 case.

Hey, started at 60 grains then 61 grains and so on to 63.5. No signs..

Wow. Great thread. Gotta admit, i was dubious. They are some seriously big charges.

How's the recoil with the Ti?

Just got in from the range, ran 200 Speers out of my Mom's Pre 70/06 Fwt with 22" barrel. Fed brass and 200 CCI's. Used H4831 regular cut and not Short Cut.

I shot one and only one round of each charge so it wasn't much of a test but did stick my toe in the H20.

It was sunny and 38* or so, and keep this in mind. I also clocked my .260 and the I did 3 rounds with the sun out went 3051/3065/3086 and 3 with it right at sun down it went 2989/2982/2982. Point being, it makes me wonder if my 06 readings were good or not?

Will add, that I'm missing the front screen for my clock so maybe this has/had something to do with it? Tons about working with a clock I don't understand.

But, to my point here's what I had for readings (one round each charge remember)

59=2629

60=2666

61=2721

62=2812

I haven't resized and reseated a primer yet. The 62 charge looked pretty flat but not like a pancake and it was just starting to crater a bit. Thinking it'd have some issues if the temp was another 30 degree or so warmer.

Will do more testing and report later.

I had another 06 with me but unfortunately the rounds wouldn't chamber in it so couldn't run two diff 06's at the same time.

Fun BG stuff to play with in the cold of winter.

Ain't the ol' 06 freekin' great?!

Yes it is great! One of my favorite big game cartridges ever!


By the way, the big gem of this whole thread is chit squezze not knowing the difference in a M1 Garand, 1903 springfield and a 1917 enfield and getting caught red fingered in his own chit again.

Hey, he's dead, cut him some slack.

Betcha five bucks that I know less than you!

Didn't notice. I shot it today without a scope too. It will have a 2.5x8 with BC reticle.


I'm used to much more out of the 300 WSM in a 7 lb rifle.

Mark,

Interesting results and worth playing and testing with!

One thing for me, for an 06, it's gotta be a 22" barrel.

yeah I want to see how the primer life is, for me I want some life or I'm gonna back off. This testing was done at fairly cool weather and I'd think it'd be a bit toasty of a load when it warms up.

Side note, my 06 and my 300 WSM both shoot 155 Hybrids into bug holes!

The 2011 Hodgdon annual manual lists actually pressure tested maximum loads with the 200gr Accubond at 59.0grs at 2586fps and the 200gr Speer sp at 57.5grs at 2577fps.

Alliant lists 58.0 GPRS of RL-22 with the 200gr Speer at 2499.

If you are loading more powder and getting higher velocities you aren't some sort of advanced reloaded or possessor of a magic "fast barrel", you are simply loaded to higher than normal pressures.

Higher pressures might or might not be safe indefinitely in your gun, just don't try and kid yourself that you aren't pushing the envelope..............dj

Mark I though you were looking hard at the scenar 155's - whats up with the 200's?

Curiosity more than anything. Both my 06 and my 300 shorty mag shoot the 155 Scenar and 155 Hybrid incredibly well.

On a thread recently about the 338/06 there was talk to the effect of use a 200 out of a 30 @ 2700 and call it a day. I've generally found somewhere in the low to mid 26's to be about top end. And had not pushed a 200 over 2600.

Long and the short I just wanted to see how the brass would handle 2700 or so.

It's winter and ballistic gack can be sort of fun to play with. I like to use primer pocket life as an indicator of pressure. So, I asked the question of those backing the idea (on the 338/06 thread)of a 30/200 @ 2700 to see if many had good case life at those speeds. Not many could report on the case life, though several reported that it was just fine.

No bigga casa grande and just fun and giggles is all.

When it's all said and done I like my .270, my 300 shorty mag and my 7 Mashburn and don't do much with the 06. All of those do what I want them to do and I'm comfy with them.

Lastly, in this day or turrets/dotz/BP or whatever I generally find top end speed and back off 100 fps. It's still easy for me to do my work at longish ranges and I don't have to push it.

One thing I did notice while playing around with an external ballisitics calculator is that using the 200gr accubond at 2700fps does allow you to keep Nosler's min impact velocity of 1800 to out past 600 yds, for the long range hunters this is a plus.

Has anyone used the Sierra 200gr GameKing on heavy critters like elk or moose?

I used to shoot 220 hornady's with rl-22 out of my '06. Velocity was around 2500 f.p.s. Worked really well on deer at woods ranges.

dj,

The SAAMI maximum pressure standard for the .30-06 is 50,000 CUP/60,000 psi, way below the standards for similar rounds such as the .270. This is solely due to older rifles in .30-06, not because of any quirks in the cartridge itself.

According to one of the basic laws of internal ballistics, when using single-based powders (such as H4831, whether standard or short-cut) pressure increases at twice the rate of veloicity.

So if we load the .30-06 to 64,000 psi (the same level as the .270), rather than the 58,000 psi level Hodgdon shows for them, then velocity will increase about 5%--right around 2700 fps.

Sounds like someone better get to a pressure testing lab, real quick! This is getting too interesting.
