I'll be loading for a new 6.5 wild cat based on a shortened 270 WSM case, shortened to hold about 4 grains less capacity to the base of the shoulder/neck junction than a 6.5x.284 Winchester. I'm hoping some folks can get me started on some good primer and powder types for a case of that capacity (not looking for amounts at this point, just which powders and primers to buy.) I'll be shooting this out of a gun with a 24" barrel, and will be using 130 through 142 grain bullets for a trip to Africa for plains game, and after that deer, black bear and the like here in the U.S.
In the past I've always used Federal 210m primers in my old .260 Rem, but I'm finding those are extremely scarce these days. Are there better large rifle primers out there for a case of this size? Also, what are most folks using in rounds like the 6.5x.284 for hunting where the temps can vary alot? I am wondering if that will put me close - or if I should be looking for faster powders given the slightly smaller case capacity and 24" barrel...
Obviously as far as overall goals, velocity is good, accuracy is better, and of course both would be just super.
Any powder and primer info would be very appreciated! Thanks for any info!
