If you were to pick one powder for 85 to 100 GR. bullets, what would you chose?

Thanks.

4064 or H 414...

others work well also, but those two are my top choices... for velocity AND accuracy...

4064 may be 100 fps behind slower powders with the 100 grainers..but I'd put its accuracy above many other powders..

RL 15 gets third place honorable mention...

Hard to argue R15, but H4350 gets my vote.

H4350 would be (and actually is) my choice as well.

Used to use IMR4350 but switched to H when I used up the last 8 pound jug of IMR. Both have given excellent accuracy and velocity with the range of weights noted across several brands and styles in three .243's and a .243AI so far.

Many loads don't completely fill the 243 case. I've found that with 100 grain bullets, old style H4831 gives 2950 FPS and a full case.

RL 15..38.7grains and a 85grainTSX. grouped well out of my model 7

Got one pard that swears by H414, and another RL-15.

H414 is a very versatile powder for the the 243, bullets light and heavy. That being said, for anything 85 grains and over I'm curently using H4350 because it's what I have on hand, and it works just fine also.

I always had excellent results with IMR-4350. If I was loading a .243 WIN today (and wasn't sitting on five pounds of IMR-4350) I would try the H-4350 from Hodgdon.

Another vote for IMR 4350

varget has been the most accurate for me, from 60 grain sierras to 100 grain bullets.


nothing wrong with the 4350 siblings though.

Thanks to all.

Another vote for H4350.

I'd do RL-17 for it all...

Right now I'm using H4895 for 55 gr Ballistic Tips, 75 V-Max and 100 Interlock.

Might try Varget , H 414 or something else soon.

H4350 works well for me.

IMR 4350.

I'll go off the reservation and say Win Supreme 780 for the heavier bullets you are referenceing. Velocity around 3100, accuracy is excellent. Meters like water too, which is always a plus.

for years i loaded either imr4350, for 100s or imr4895, for 85s &90s...

when i decided that 85s and 90s did all that i wanted from the .243 i started experimenting with powders...

didn't notice a nickels differnce between imr4895, RL15, or varget...

even later, i discovered the 70 gr ballistic tip... for that i preferred RL15, and my buddy went to varget for the same bullet...

I have had good luck with Ramshot Hunter with 95 gr. SST's.

IMR4350 OR H4350.

IMR-4064

I started loading the .243 in 1974, and IMR4350 was definitely the choice as an all-around powder for 85-100 grain bullets back then.

These days I've had excellent luck in various .243's with 85-100 grain bullets using Hunter and H4350. I'd tend to pick either of those over IMR4350 if you hunt in widely varying temperatures--and I see you list "NM" as where you live, which I assume means New Mexico, a state of extremes in both terrain and temperature.

When I saw this thread my answer was going to be H4350... I see John and others beat me to it!

Great minds....

If I were going strictly with 100s, I'd day H4831 or MRP. With the lighter bullets thrown in, I'd say one of the 4350s.

Couldn't find a load that worked until I tried 4320

Either H414 or IMR4350. Take yer pick.

imr4350 since 1971. Might try something different this year..

Thanks again to all, have some H4350 on the way.

Yes, those would be my suggestions as well.

just because you need a little support...

4064 is my first choice, and H 414 second if I need more velocity..I've always found it a hair more accurate in mine than the 4350s...while being a 100 fps slower... which never bothered me..

+1...

Never tried IMR 4350, but H414 has been proven in my Marlin.. velocity easily tops factory loads with 100gr Hornady SP Interlocks. Accurate at top speed.

Another vote for IMR 4350..been using it for years,gives top velocity and accuracy in my guns.

My dad has been using IMR4350 and 95gr Ballistic Tips in his M700 BDL 243 for 30+ years, he's killed a ton of deer in that time, I've seen him make some pretty impressive shots with that combo as well.

+1

I use H4350 for my 243 win and the 85gt tsx and 80gr ttsx. Very accurate and good speed.

I had Retumbo recommend to me for 105gr VLD's. Will try it soon.

Bob

Ya'll IMR and 4350 folks really need to try some RL-17 if you can get your hands on some...

H4350 is very temp stable, which to me is a big deal. When I made loads and shoot them at 80F and then go hunting when it's -30F they need to shoot pretty much the same. I haven't had much luck regarding the RL (17 and 22) in this regard.

Always had good luck with IMR 4350 for an all around powder in the 243, plus it loads well in other cartridges I shoot as well.
H4350 is more temp stable, but I've loaded IMR 4350 since the 70's with never any issues due to it from desert to mountains.
If I ever shoot up my pile of IMR 4350 I might go with something else.
I generally shoot faster powder with the lighter bullets (4064, varget or RL15).

Good Luck,
Ted

In the past IMR4350 was ALWAYS my go to powder, though I did run Varget and H414 under 70s for a varmint load w/good success.

Recently out of the IMR so burned up some RL19 w/good results using 70s, 95s and 105s. 9 twist does pretty well. Had one group of 6 shots, whole thing smaller than a dime, at 100 yds, 3 were 70s, 3 were 105s, the 70s were shot using a less than dime and each 3 shot group was about 1/4", was very surprised, and happy. Must have gotten lucky

No doubt the 243 is an overbore round, and can utilize slower powders, one thing to consider is I believe Nosler's data on 243 and 6mm, there are some interesting speeds well above the norm w/say IMR4350, when using powders that often get used in small bore magnums. Seems the speed was boosted a good bit, not sure on accuracy.

Suffice to say, at 2900-3000, typical speeds w/4350s, and 95/100s, deer/hog sized game drop fine when the shooter puts them thru vitals.

Recently I replaced the IMR w/H4350, as in my 260s, it's reported to give 50-75fps or more over IMR. I figured why pass on free speed.

IMR4350 was often a go to back in my college days w/many range members in their 270s, '06's, as well as 243. It works just as good today. Accuracy from 3/8" to 3/4" has been routine in several rifles including a #1A and #1RSI, both new out the box. Must say I have had few problems ever finding good loads for 243s, they all seem to want to shoot sub moa easily IME.

Do note, FC and WW brass did better overall the RP. I'd use either and consider Nosler/Lapua for the ultimate, as those 4 would be solid choices for tight groups. Recently I have tried some Noz (mfg. by Norma from what I hear) and it's very good brass.

RL15 for me

When I first started loading for the 243 I gave Sierra a call since I use a lot of their bullets... Talked to a guy for about 30 minutes and he gave me his favorite load for the 243.... Haven't been disappointed with it yet... IMR 4831 is working well for me with 85, 95, 100, and 105's ... like a previous post the RL-17 has worked pretty well also... I have tried the H4350 and got real good results, but none equaled the accuracy of these powders for me or the speed... Matter of fact I bought 8 lbs of H 4350 because it was so highly recommend, now 15 lbs are sitting in the cabinet ... getting ready to give it a run in the 243 AI with some 95 and 105's to see if I can tighten up some groups... Got some good groups with the 105's at just under 3100 with the IMR & RL but not good enough... the H4350 may bring these in a little tighter, but leaning more toward H-1000... Got a friend using Hybrid-V with the 95 Bergers running around 3000 and dropping Florida Hogs and Deer with 1 shot pretty regular ...

I'd run Hunter or RL19 and never look back. Hunter would get the first place.

I am going to try H-4895 and 85 grain partitions ,I hope it works ok as I have very technical and specific reasons for using it.
I already have it ! Dont want to drop 30-40 more bucks for another Powder !
I am going to be shooting for good accuracy and 3000-3100 FPS out of a Remington 7600 243

Craig

Anybody choose different powders for the same bullets in a .243 and a .244/6mm Remington?

Don't know about Hunter, but RL17 should rate a try.

3,400 with an 80ttsx.

You may not like that bullet though...

H4350 and RS Hunter with over 75 grs bullets. Under RL 15 or Big Game.

I have been shooting 243's since the mid 70's. About 2 years ago, I tried R#19 with win primers with the 85g tripple shock and had Clover leaf groups with SPEED!

85g Tripple shock shot a hole from one end of a doe to the other, broke a hip and front shoulder, lodged under skin.

R#19 stomped my 4350 and 4831 loads, and R#22 was not Super accurate in my rifle.

Keith,

RL-19 is great in the 6mm Remington too--which it should be, since it's pretty darn close to the .243!

Another great, even newer .243 powder is Ramshot Hunter, which has a very similar burn-rate to RL-19.

Like you, I've been shooting the .243 since the mid-70's and the newer powders do make a difference in many rifles.

Best groups I got from the 100s in my 243 actually came from H-1000. Best velocity, too (within the context of excellent precision). That said, 780 was showing promise with the heavies when I quit and sold the 243.
For overall flexibility, though, 760 was the powder for me.

Back when it was available, I liked H-450 in my .243 Win 100 gr bullet loads. IMR-4350 was always a fallback. I currently am loading my 90, 95 and 100 gr bullets with Accurate Data 86 Extruded Powder. Sort of a cannister grade version of Accurate 3100. It works very well in my .243 Win with bullets from 70 gr up, also performs fine in the 6.5x55 and the .270WSM, which is good since I bought 24 lbs of it when it was offered by Powder Valley a few years ago. Still have over 16 lbs of it left. Paid about $10 per pound for it delivered. One of my better investments, as it has turned out.

H414 from 55 grainers to 90 grainers. Good speed and accuracy, just not as temp sensitive. When my 8lb jug runs dry I will be making the move to Hunter though.

H414 is the one powder my rifle said would do it all 10 years ago, and I haven't looked back since. Prior to that 3031 and 4350 were the powders I used.

Winchetser 760 or its twin H 414.
