Ok this a quick it will work kinda thing, I am posting without permission of anyone but results are what they are.... I recently did a bbl for a forum friend and his 4,5 Matador...
Here are some quick results to ponder. All at 47 yds, same tune 905 ish for 15.6 nsa hp fb. ,178 dia.
Slugs ,75"
Jsb 13 gr redisgined monster this is 19 shots and 1 off regulator. Ignore high one it was a sighter. .375"
10.34 gr edgun pellets this is 30 in ,55"
The bbl is a Walther un choked poly , chambered to ,180 dia .200 deep with a 1,5 degree lead. I won't get to experiment more with this gun as it's going home to a nice guy I hope doesn't mind the post...but I thought it was neat and worked well
Btw it may do a little better I was just laying on the ground prone shooting in some moss...no front rest just traditional prone. The rifle is so quiet and tame to shoot it's amazing,,, the goal was to shoot the 23 grn. But it is so sweet with the 15 and much efficiency is lost with the 23 due to bore friction. It will need test to see if it's worth it.
