I've been loading 16ga, 2-3/4 RGL's for my 2-1/2" grouse gun for about 10 years without issue. 6160psi with 7/8oz at 1119fps. Its the 20/28 load off of the 16ga forum.

In my 20ga damascus Flues, I also shot 2-3/4' reloads @ about 7k. Chambers were 2-1/2" with good barrel wall thickness. I wouldn't think twice about it if the barrels are good.

Hope this helps.

Bill
