I bought some 340 grain SWC-Keith style bullets for my .480 Ruger and I'm looking for some help with load data. I'd like to run them around 950 fps. Preferably with Unique or 2400 powder.
Most of the load data, in my manuals, is for cup and core bullets at full power. The closest cast bullet data I have, is for a 325 grain bullet and starts at over 1100 fps. Searching the internet doesn't seem to come up with any data for this weight.
The bullet is from Montana Bullet Works and from the description, I assume it is a LBT produced mold.
Any help would be appreciated.
