Re: Rem 870 Hastings Barrel Problem
A hunting buddy of mine had the same problem but he has an 1100 with the muzzel break. Like you, he spent a ton of money on slugs, and talk to a rep from hastings and they told him the same thing "winchesters or federals". Well nothing worked and after all he got some hastings sabots, and they shoot great at 100yards. But the slugs are a lot heavier than any other slugs out there. I believe its something like 547 grains. Give them a try if you haven't already, but hopefully you get it figured out.
Be sure you put your feet in the right place, then stand firm.
