Limited magwell. I just started to work up a load last night. When changing the primer charger, the spring went TWANG, and disappeared in the shop. Spent an hour looking for that thing, and never found it. I'll order two today.
The load I was getting ready to try is a 170 grain SWC with 6.5 grs of bluedot.
I have a couple of pounds of bluedot in the cabinet that I bought for heavy load shotshells a couple of years ago. It needs to be used, so called Alliant and got the suggested powder load to start at. He said it would be pretty soft, and may not work the action, so its a starting point.
Whats your load?
