Hi Bill, where you at? I'm from Colden. I have Browning Hi-Wall in Hornet. I tried 12.5 gr. of lilgun with Hornady 45 gr.HP and got signs of pressure,- stretched cases, poor groups etc. backed down to 9.5 gr and put 3 almost through the same hole at 50 yds. Now I'll start working up again. What is your favorite load in the Hi-Wall? I just found this forum a couple of minutes ago, seems pretty good. I usually play with the 17M2. Till next time
Just south of Jamestown. I am up your way often for business. In fact I have to be there Friday.
I don't think your pressure issues are from 12.5 grains of Lil Gun with with that bullet.
If I were you I would consult with Rocky, Jim or others here on what the issue may be.
Got to run........off for the evening "Wodchuck Hatch"
now.
Regards,
Bill
