Your A-bolt will probably shoot multiple different slugs, but every Browning I've ever shot especially loved the Partition Golds.
My H&R Ultra would shoot the same hole 10X in a row with them. Oddly, it didn't like the AccuTips

My H&R nor my Savage 220 will shoot any Hornady slugs whatsoever, it's like with with either of them every other shot was a 6" flyer.....all over the target. I wanted to shoot those new Superformance slugs BAD, but no go.
