That is some fine shooting unsupported for sure. That must have put you on the top of the leader board.
Shooting a couple friends BSA I always felt I would like to have one.
I like the action and all of those rifles shot very good.
Sam I have a CPA with a heavy barrel like yours. Mine is 1" at the muzzle and 1-1/4 at the breach 28" long it comes in just over 12#
I had it build it matching my silhouette rifle for of hand practice to boost my Chicken scores up

I tested several different brands of .22 shells and all in all this rifle will shoot just about any of them.
This target I had the rifle double sand bagged front and rear to see what it will do at 100 yds.
It was surprising that this rifle shot the low end shells as well as the $20. stuff. I never shot the Eley yet but I will down the line to see what they will do. I still have 1-1/2 cases of Norma match I bought on a Black Friday sale one for $100. and the first for $200. They might out last my shooting them.
Those orange stickers are 2"
