It ought to be fine shooting it out of that Model 70. The only problem I've ever run into with CAVIM brass was with my M1A. The batch I had was really hard brass. Found that out when I re-sized it for reloading, and I should have stopped there. The only extraction problems I've ever had with my rifle was with that CAVIM reloaded ammo. Had the first failures to extract, and almost every round did it. I loaded it to U.S. GI M-80 specs, but this stuff was worse than useless. I toss any CAVIM brass into the recycle can whenever I find it.
