ERE!! I think he said 30 cal. So 250-249 won’t work? I shoot .302 out of a converted m-d at 953 fps Slug is Krytek coated and wt is 55 grain I only get 5 shots and the cliff is sharp but for the midnight barn raider it works. I have an Jager 30 cal shoots same bullet at 965 fps and get 1 mag out it, not as steep of cliff. the same jager shoots 44.75 gr pellets at 1047 ft per second down to973 1 mag but this gun is a tack driver with both slug and pellet. what can one get an impact to do with 55 grain cast slugs and what barrel do you order?
