I'm running 95gr SMK's and looking for a good powder for a reasonable price. I've tried RL-17, seemed to be a decent powder, I've tried H4350 and had good results with it as well. I've bought a new LNL powder dispenser so it will need to flow well with that dispenser. The H4350 bridges a lot so I don't think that is a choice that I would want to buy 8lbs of. I didn't own the LNL when I tried the RL-17 so I can't comment on its dispensing.
 
Try IMR7828 SC for your 95's and H4831 SC for 87 to 65 grain bullets. I posted a pic of 100 grn. Sierra Gameking with 45.5 grns of 7828 SC in the rifles section the thread title is "cheap accuracy" good luck
 
Shooter,

If I were starting on a new .243 today the first thing I'd buy as a component would be the Hornady Interbond bullet, one hundred gr for hunting and maybe something in the 75gr for very long range varmint. Although I'd have
a.22-250 for varmint.

With powder I'd start with H-Varget, simply because I shoot it in so many different rifles. If H-Varget didn't make me happy then I'd pull out H-4350 and give it a try. I've had so much experience with both powders in a .234 I just can't imagene trouble with either of those powders.

Primers would have to be the CCI BR2. It may cost a little more than other primers bur after many test it is the only primer I'll use in standard cartridges.

Well that's my opinion, it and a dollar bill might get you a cup of coffee. Let
us know how it works out for you
 
I have been running reloder 22 out of a rcbs chargemaster and a regular old rcbs thrower. It is not the best metering, but if I take my time and trickle it works fine.

That powder has given me very good accuracy and has dropped quite a few deer. Shoots sub minute groups pretty easily. Not sure on the exact velocity off the top of my head. Around 2900 I think. Could be wrong though.
 
Varget and IMR-4064 cover all of my 243 loadings. I have been thinking about trying some of this RE-17 that performs so well in my 30-06.
 
You'll find that Win760/H414 gives great performance and flows through a measure like water. I suggest using magnum primers with the ball powders.
Rel-17 works very well in the 243 Win, but no idea if your measure will handle it well.

There are some new powders on the scene that show great promise, but I have no experience with them.
Check out www.hodgdon.com and www.alliantpowder.com and compare.

Well hell, I'll have to give the Varget a try seeing how I have 4lbs of the stuff I bought for the 308 but haven't tried. Mag primers for the 760/414? Is it really that hard to light off?

I'll load up 15 rounds for this weekend and see how it does.
 
It was nice to read this thread. I've had real good luck with H4350. I have several test loads put together with Supreme 780 and Hybrid 100V but I haven't been able to shoot them yet. I hadn't even thought about trying the RL 17 and RL 22 even though I have a couple cans of each. Those are all for the 95 and 100 gr bullets. I need to find some load data for the 75 gr bullets I got in now. And I need to figure out a good load for the Ramshot powders I have.

Nice thing about the .243 is it doesn't seem too picky. Just about any powder I have used gets pretty decent results and it makes me feel like a real expert. :)
 
:D

Gotta agree with that statement, funshooter, the 243 is easy to shoot easy, it's hard to find a combo that doesn't work! Maybe a new thread call what won't work in your 243 would be better.
 
I have huge temp swings here in Vegas. So keep that in mind. I've been told the RL-17 was designed to be a close match to Varget. I've used the 4064 in 308 here but rounds that run well in the winter, over pressure in the summer.

Thanks for the suggestions.
 
R-15 and varget are almost twins I believe. I run varget and hybrid 100. varget behind a 75gr varminter, and hybrid 100 behind a 85gr tsx and they both shoot 1/2 moa at identical POI at 300. But like has been said what doesn't work in the best cartridge ever invented:D varget will be very forgiving as will r-15
 
Ramshot Hunter is a spherical (ball) that meters very well, is temperature insensitive and burn rate is about like R-19. Nearly ideal for .243!;)
 
Sin City Shooter,

I :)have had great results using H-4350 and H-Varget. I think either one will give you what you're looking for.
 
I just wanted to bump this thread to thank Funshooter45. I tried both the Supreme 780 and the Hybrid 100v. Both meter extremely well (slight edge to the 780) and both seemed to shoot very similar to the H4350. I read that the Hybrid 100v is basically H4350 but has been cut even shorter and has rounded ends. I tested all 3 powders this weekend with 95gr SMK. The wind was blowing a good 20 mph+. I thought all 3 performed great considering how hard it was blowing. I just ordered 8lb of the Hybrid 100v, but would have no problems with having the Supreme 780 on my shelf either. I've seen some posts regarding the need for mag primers to light the 780 off. Is that really necessary? I had no problems with standard LRP.
 
I have been running 41.5gn of IMR-4350 behind 95gn Berger vld-h, with great results. RL-17 seems to be the short cut and temp insensitive version of imr-4350, i bought a pound to try.

Will post results when my 5 week old son lets me go to the range. :)
 
Yeah, I liked the RL-17 too. I was looking for something that didn't bridge in my LnL powder thrower. I had ran out of the RL-17 before the new dispenser arrived. I think the guys here are right, it would probably be easier to say what doesn't work in the 243.
 
I run 38 grs of IMR 4064 behind a Sierra 85 gr HPBT for varmints and 40 grs IMR 4350 behind a Sierra 100 gr SP for when I use this for deer hunting.

Congrats.


I tried some IMR 4064 under a 65gr V-Max & wow it was great. i most be doing something wrong with Varget because it is by far the worst powder in all but one of my rifles & even in that one it's no better then anything else.

I guess the Varget is better then the WC 872.
