A friend wants me to load for a 40x to be used for P dogs.
I have 748, 4895 ,Acc 2230 on hand.
I don't know the twist in the 40x but he is thinking 50 gr bullets. I have hornady and sierra on hand .
Hard to say regarding twist with a 40X. Most .22-250s, especially in older days, were 1-14", but the 40X could be ordered with a variety of twists.
I wore out a Ruger 77 "tanger" varmint rifle shooting 50 grain Hornady SXes and 40 grains of H380. I wore out a Remington 700 LVSF shooting about a 50/50 mix of 50 grain SXes and 50 grain TNTs, both over 37.5 grains of Varget. All above were with WW brass and Fed 210M primers. The varget load was likely excessive but it is where the accuracy was. Drop a half grain and the gun went from wildly sub MOA (I shot a lot of groups in the low-mid .2s for 5 shots) to well over 2 MOA. So that's what I shot and critters **died**.
