Got a tikka sporter260 in a xlr chassis. I was using la mags in the original laminate stock and worked great. My current load is 142 smk, lapua brass and 44.1 gr h4350@ 2.330 oal from ogive. That length isn't close to fitting in an aics mag. I would need to seat bullets to 2.295" to fit and feed without tips dragging. That would be a .055" jump, hate to jack with the load much as it gets me 2850mv, 7.xx sd, and shoots in the .3-.4" ave and put 5 rds into snuff can size groups at 800. I have saw good and bad reviews of the type 2 mags, just seems like the bad reviews are more current. All different sources on the net, what's the folks at the hide say?
