243 Powder Choice

[kdvarmint]

What's a good powder for 243 pushing 105gr bullets? Currently using IMR4350 but doesn't fill the case. Considering IMR4831.

[Uncle Jack]

You may want to look at Hodgdon Hybrid 100V along with H4831 SC.

Read a little about it. Do you have experience with it?

[Uncle Jack]

Yup. I don't suggest specific loading data to people online, but I have had very good results with 100V in several cartridges that work well with 4350 or 4931. The burning rate is right in the middle and it measures easily. Check out the Hodgdon website. http://data.hodgdon.com/main_menu.asp

kd,
H4831sc is the most consistent powder I've tried with 105Amax. Been using it as my "go to" heavy bullet powder for about 3 years now in the 243 Win........Gives a fairly full case I get little vertical in my groups....I use Varget on the lighter bullets (but I don't shoot many of them).

By far the best powder I have found.

Hi a full house of rl22 will get you to that magic 3000 fps number,
or supreme 780 if hogdon is your fancy,
they have the same burn rate.

I've used IMR4350, H4350, IMR4320, but the most accurate has been AA4064 for me.

Any comments on Ramshot Big Game with 105 Amax? Acceptable for pds?

[kdvarmint]

Well I bought some Hybrid 100 V. Will let you know how it works. Might be a week or two. Thanks for all your opinions!!

Poor, Poor results. Tightest group just under inch and a quarter. Biggest a little over two. Bummer.

[keeki]

you might want to give rl17 a try. ive used imr4831 for 15 years now for several loads and rl17 has all but replaced it

Never shot the 105gr. bullet, my twist won't spin them, but I've had great results with Supreme 780 in 95's and 100's. Excellent accuracy and velocity.

47.0 grs of IMR-4350 @ 3700fps with zero pressure signs in my remington setup...

Groups are .23" at 100yds and ground hogs are dead at 500yd....

Wow, yeah? I'm loading 38.2 grains imr4350 with 105 A-Max.

[scope eye]

Would have to be a 65gr vmax at the most to get that velocity.

I started loading Retumbo with 105 Amax's a few years back, verygood results out to 600 yards. They kill Deer pretty darn good also. Since then we have loaded Retumbo and H1000 and shot very tight out to 850 yards under a 105 Amax. I've loaded some Ramshot Big Game under 100 gr BTSP's that show promise out to 300 yards.

Getting 3350 out of a 18" barreled BLR with a 80 gr TTSX over RL17.
