Trying to decide what to shoot out of my new/used Great Plains Hunter once I get it 'tuned up' with the new sights, frizzen and flash hole liner.
I want something I can get right now so the Bullshops are out. I have some 250 gr REALs, 275 gr Maxihunters and I will be getting a 320 gr REAL mold next week.
You guys think the Powerbelts or similar will shoot OK out of this barrel?

yes, the powerbelts should do really well. My dads cabelas hawken shoots the 295s, 270plats and the 348s excellent. The heavier ones shoot better. His seems to have a wee bit larger bore than my other 50s

I think the 320 REALs are likely to do real well out of that 1 in 32" twist with something like 70 grains. If they do you'll have a great inexpensive bullet.
