I recently purchased an 12 ga. H&R Ultra Slug Hunter. I put a Bushnell 3200 Firefly scope on it, and picked up a few boxes of Winchester Supreme XP3 sabot slugs (2-3/4" 300 gr. 2000 fps) to go sight it in.

I was ok (not great) at 50 yards, and all over the place at 100. Since then I have read some bad reviews on this Winchester ammo, and have also read that this particular shotgun can be real picky with the type of ammo it likes.

I have read that Federal Premium Barnes Expanders, Lightfield Commander, and Hornady SSTs are better options than the Winchester.

My question is - has anyone here had some experience with any or all of these ammo brands with a slug gun? What's your opinion of where I should go from here?

Thanks in advance
