I run a 24" barrel with 1:12 twist.
IMR 8208 XBR got me to 2900 fps when I started seeing pressure signs.
Varget produced 2925 fps safely and will probably be my hunting load.
I used Hornady brass and CCI 250s for both loads, but I think I could gain 25 fps with comparable pressure by switching to CCI 200 and upping the charge by a half a grain or so. I think 8208 especially would benefit from the cooler primer because of how fast it burns.
I'll probably just switch to CCI 200 primers, load my max charge of Varget, confirm velocity and accuracy, and call it good for this deer season. I'll continue load development next year if I get frisky.
I realize this is somewhat overkill for whitetail, but Iowa demands 35 cal or bigger, so I built it out of malicious compliance. Recoil is the only downside, it'll put one on you shooting from a bench in a t-shirt.
