RE: Turkey Choke Constriction
I use a .670 out of my 835. I've also shot a .680, .690 and a .695. The .670 shot the best with every load I tried bar none... but it doesn't always work out that way. The 835 is overbored anyway, so its automatically a bit more open, so if you wanted to try a .665, then it might work out. My .670 shoots lead OK, but it really shines with the high density shot.... Winchester Extended range is what I shot for a few years until I shot some Hevi-13 this spring, and it blows everything else I've ever shot out of the water.
