Thanks for the info. My current load is 50 grains of H322 with a 300 grain Hornady XTP. The best I can get out of it right now is 2.5-3" at 100yds. My barrel is a custom E.A. Brown .905" straight bull it is guranteed for 1" at 100yds. I'm still trying to work out the bugs.Anymore tricks?
Is your barrel braked? Is the forend floated? Have you taken steps to eliminate the human factor in your benchresting technigue as much as possible?
I won't call your shooting ability into question but will simply state from my own experience that fatigue will definately be a factor with this round in a handgun.
You could also experiment with bullet seating depth if your throat allows it and crimping amount. Also try a lighter bullet if you can. What is the barrel twist rate? Did you state what bullet weights you would be shooting to the barrel maker?
What power scope are you using? 3 rings or 4?
Just some random thoughts thrown out to you to get the wheels turning.
Thanks for the info.To answer your questions, no, the barrel is not ported,or braked.No it is not floated. I did my best to eliminate the human factor by bagging the **** out of it.I have a 6 screw 3 ring mount with a tasco trophy elite 2-6 x32 scope. I have tried diferent bullet seatings. The longer the better is what I have found out so far. The twist rate is 1in16.I have not tried any lighter bullets due to the fact that a lighter bullet at a high velocity my not handle the energy and cripple more animals than it will kill. I am going to try to tinker a little this weekend. I will let you know what I came up with. Thanks again.
