243 powder?

[mrultramag]

Just picked up a 243 Ruger in 9 twist, 22" barrel. Hope to cover about 500yds with it. Thinking 95 gr Berger classic as a start bullet.
What powders work with the round best? Thinking of RL16. Have a lot of RL26 anyone try it in 243? Have a lot of H4831sc.

I load rl 26 and 95 gr ballistic tip. 3150 fps with a fairly mild very accurate load. No real load development. It shot good out of the gate...24 inch barrel

Have the same gun. Got the 95 grain burgers to shoot with H4350 . Will easily shoot great groups out to 600. Have good hits out to 1000

I'm thanking maybe try the superformance powder. I would at least try a faster burning powder do to the short barrel. My opinion slow burning powders are for long barrels. Fast Burning powders would be more for short barrels. I have never tried RL26 but it appears to be good for longer barrels and heavy bullets.

If you can't find superformance then try StaBall 6.5 Or hybrid v100 should be similar results

Never loaded the 95gr bullets but did load for the 115 dtacs with retumbo and H1000. Also loaded the 105 amax and 107 sierras with the same powder.

I checked my data. This was in a Winchester M70 Stainless Classic Featherweight

Nosler 100 gr Partition
Winchester Brass
CCI #200 Large Rifle primer
RL-26

Worked loads up from 47.0 to 47.8 grains. Peak (mean) velocity (Oehler chrono) was 3198 FPS @ 47.8 gr. Accuracy was coming apart, maybe a little pressure there.

Settled on 47.2 gr @ 3153 FPS. Group was 0.52". I reloaded and checked seating depth several months later and the load was about 1", although the change in accuracy could easily have been the shooter.

Good luck!

Seems its one of the most powder friendly rounds out there, most powders seem to do really well in it.

Think I will try h4831sc and RL26 first, since I have about 8lbs of each.

That sounds like it's worth giving a try in the Cooper!

fter checking out Nosler load data web site I would say your in the ball park. They tested the RL17 to be the most accurate powder for the 95-100 gr bullets. You might want to look at the H4350. It has very near the same performance data as the RL17. I use the IMR 4350 in my .243, .340. and .375 with good results.

IMR4320 has served well with the heavier 95 & 100 gr bullets. Varget behind a light bullet is awesome.

By the way, this is in a rifle with an 20" barrel that is at least 60 years old.

I've tried quite a few powders in the .243. I use IMR 3031 for 55gr and they haul butt! I haven't tried anything else with 55s because I haven't needed to. With 87gr hpbt, Superformance works good in my 20" gun. Pretty sure I've tried IMR7828ssc and possibly H4350. 95gr my best load was with H4350 in my 26" .243. 105gr hpbt, I've tried IMR7828ssc, H4831sc and H1000. They all worked but I hit gold with a case full of H1000. I've considered trying RL16 and H4350 with the 105s for the heck of it, but I haven't been bored enough yet to mess with it. I've also heard that RL26 is pretty awesome with 105s but....same story.

When you hit that boredom level try Staball 6.5 and Hybrid 100V as well. They have

Been looking for H4350 for 2 yrs none here locally at all.

I think Butterbean called it. I like RL16.

Edit: Of course thats before I read what you have on hand above.

I wanna try some N555 with a 105/108 and see what comes from that
