Yee Hah!

Took almost two years, but I've finally made Senior Member!! The way I type it may only be another five years before I hit 500.

All that aside, can you shoot 45lc in a single shot H&R .410 shotgun or is that a kaboom waiting to happen? I have a whole box of 45lc, but unfortunately my Vaquero has gone the way of the Buffalo. If I cant use it I guess I'll give it to someone that can.

What choke does your H&R Topper have?
That will be the determining factor. Most .410 Toppers have a full choke.
If it is smaller than .452 you're gonna have a problem.

The chamber certainly has enough steel to handle most factory .45 Colt loads.
However that smooth bore will give you horrible accuracy.

Bluesbear-
To be honest, I'm not sure how it's choked. I guess I can Mic the barrel and see. It's the little Wally World cheapy. So if I have more than .452 I should be ok?
