How much would it cost to start loading for this chamber? Brass and dies to get started seems to be pretty expensive. For dies, would I be able to use non custom dies? I like lee dies, so would I be able to use a 22-250AI neck collet die, 22 BR seater, and since I like it, some sort of factory crimp? For brass, would I be able to form some out of, say, 22-250 brass? I know lapua brass is great and seems to last forever in this chambering, but at $1.09 a pop it is still pretty expensive. Would I even be able to neck down brass without a bushing die or custom .22x47 die? I mostly target shoot and prairie dog hunt, and I feel like being able to shoot heavy bullets a higher velocity would be pretty effective. The cheapest route I can figure is just rechamber my factory .223 with 1/2 moa accuracy to something with a little more capacity and really liked the 22x47 performance. A 22-250 with a 1-9 twist would work, but it is not a good on barrel life, cases, and it supposedly will heat up much faster according to many accounts on LRH. I have been looking at rechambering my marlin x7vh (basically a savage action) in .223 with a 1/9 twist 26" varmint contour. It shoots about a 1/2 moa as of now with 53 grain vmaxes, H4895 and cci 41 primers. It's really the only powder/primer combo I have tried so I figure I could get more accuracy out of it if I tried harder. Thanks for any info you can help me out with!
