I've got several loads ready to go in the 200 grain range using H4831SC and H4350 for my 30-06 to further some testing I did last week.
But when I built the rifle I had heavies in mind, specifically the 230 SMK and 230 Berger. When I tried these two 230s last week, the only powder I used was H4350 and I didn't get good results at all. I haven't given up just yet on the idea of 230s and I wanted to try a slower burning powder so I picked up some Reloader22.
Alliant lists RL22 as a magnum rifle powder, but also notes that it could be use with heavy bullets in a standard (non magnum) cartridge. For their load data they only go up to 200gr bullets though for the 30-06.
I've found quite a bit of published load data for 220s, but the only published data I've found for the 230s is from Sierra which I guess could be relied upon since after all, it is their bullet.
The Sierra data list 54.4 as the highest 'regular pressure' load for RL22 which gets 2490fps out of a 24inch pipe. The loads go up from there maxing out at 55.2g and 2540fps, but are listed as 'high pressure' loads.
I was thinking of starting at 54gn and going up from there with a goal of around 2500fps.
My barrel is 30 inches and 1 in 8 twist.
Does anyone have any suggestions for this second attempt at launching 230s using Reloader22?
Also, should I be using magnum primers with this load?
