    Ok I’m going to be trying some 65g bullets they are the cutting edge cooper bullets. I was wondering what you guys would think of using varget for powder for these? I have quit of bit of it and know it’s a pretty good for stability. But would I be leaving quit a bit of velocity on the table for this caliper? Any advice would be great if varget wouldn’t be good I might go with rl16. Thanks

    Varget might be near the limit for 65 grainers and it's bit slower brother ADI2209 would be the better choice if you're wanting to launch them fast.
    The 22-243 is known in a couple of similar guises and correctly as 243 Middlestead and the very similar 22 CHeetah. Working from data you can find for these should be safe. The Cheetah is slightly more powerful due to the blown forward shoulder and resultant higher capacity. It's formed from 308 BR brass.

    Some links for study:

    None of the data I have went past 55 gr.

    Load safe friend.

    In my 22/243 I've always looked up 243 load data for the bullet weight I'm shooting in the 22/243 and used the minium 243 powder weight shown. For 65gr bullets I'm seeing seceral loads for varget in a 243. You should be fine backing that load data down for a 22/243.

    I have a 22-284, in that I am using R-25 with an 80 grain berger. I have also used N-570 as well, it worked well but was a pain to load as those kernels are so big and hard to get into the case.
    I am shooting them out of a Brux 1 in 8 twist barrel.

    H 414 would be one of my choices but not themperature stable. IMO RL 23 would be ideal. Supposed to be very temperature stable and great speed. Accurate and fast in my 22-250 Ackley with 75-80 gr bullets.
