Bart, it's the 308 that's giving me all the trouble. But it's possable the problem you post. As far as the original stock touching, the SPSs are noted for that. Flimsy plastic stock. Works fine as long as a bypod isn't used or the rifle is supportd well aft on a rest.
SPSs got good revies for accuricy. I was taken aback when it threw bullets all over the place. I've thought about selling it but I'd rather pay to re-barrel it than sell someone my lemon.
This is what the 06 does with 150s.
1/2" diamond.
