Buy 1 to 2 boxes of several different brands and try each one out. Go with the ones that give you the best groups at your sight in range. The prob;em with recommending a certain round is that what works in one gun perfectly, may worl like cr@p in the same make, model, and gauge for someone else. A prime example:
i have 2 Mossberg 200Ks one love Winchester 2 3\4 inch 1 oz. slugs, the other one prefers Federal 2 3\4 inch slugs, but both run acceptably with Remington 1 oz slugs in 2\34 inch. Just depends on the gun.
As stated above, buy 'em and try 'em. Best of luck.
If I have to explain why I ride, you wouldn't understand. Explaining sex to an alien would be easier than explaining the feeling, one that boils all that is going on in your life down to what really matters each time you are in The Wind. All I can say is, Life is not Life without it.
