Hi team, New to the site and so far loving what I'm seeing. Infact looked up a load for a specific cartridge I use to find it was literally exactly what I load and results I get. I do however a few projects on the go, currently finishing a 25CM build which I'll start some load development with very soon, think I have this squared away. Next I am looking at a 20BRA build running Berger 55g LRBT projectiles through a 1:9, 3 Groove, 28" long which once work is done will likely be 26". Seem to have a starting point with AR-2208 but wonder if something else may be better, subject to availability of course. The other is a .22-243Ai running Swift Scirocco 75g through a 24" 4 Groove, 1:7.5 twist, have tried StaBall 6.5 but wonder if there is something better.
These 2 cartridges as you can imagine are rather difficult to get any info on. If you have any feedback that'd be great. Cheers Craig
Craig, we have added the .20 BR. You find load data here: https://www.xxlreloading.com/calibers/.20-br. We are cautious to add Wildcat calibers before we have sufficient data to quality check and calibrate our models.
Working on the. .243 Ackley Improved next. Hope this already helps ...
