Powerbelts in a 1 in 48 hawkin? Nope, I am the posterboy for the antipowerbelts movement. They took 30 dollars of my money and I hated them. Would shoot great below 90gr of powder.

Roskoe, you got to remember, this sucker will smack the crap out of you with 90gr of ffg Goex and 350gr maxihunter. A lot more felt recoil than any 150gr load I have used in my inlines. I don't think I want to try 100gr of fffg 777 with that big a conical. Not sure if it would handle that heavy a load.
