I have cz 550 varmit laminated stock 22-250 that I am trying to work up a good ground hog/coyote load for. I have tried several powders,H380,Varget,H4895 and get about the same group with each using 40 and 55grn Vmax and 52 grn Sierra hpbt. I am having problems trying to get the correct seating depth on each. My gun must have a long cut throat. When I try to seat them out near the lands (within 5-10 thousands) I don.t have enough seating depth for my bullets. The 40grn goes in less than 1/8" and the 55grn goes slightly father but not enough to hold the bullet. Does anybody have any suggestion or have had the same problem? The groups can be covered with a quarter most of the time at 100yds,but I believe it should do beter.
