Well I opened a factory round an I will be damed if it doesnt look just like 296. it was as 22 grains. They list the max at 21.3 on the web site. I loaded some at 21.5 and 22.5 with a long col of 1.80 which is half way between the cannelure and the base of the bullet. also the max load of 2400 was 14.3 for 1400 ft se that they listed. With the 1.80 col I loaded 14,15,16 grains. Hopefully this will help. Also had some barrel wobble when opened so fixed that with a little electric tape between the forearm spacer and forearm. The only other thing it could be if this dont work is the fit. It was factory done but as i previously mentioned the release is all the way up when closed and no movement at all. So high the hole in the release latch is visable clearly. i hope i dont have to send it back.
