I want to hop in with a Cimarron arms low wall in 32 WCF. 46 inches long and I bet it weighs almost the same as yours. I just picked it up from gun shop. I found that the the sights were set at 50 yards.
I went by Cabela's last week and the fella in the gun library and I were talking. I mentioned buying the low wall and he said he is he original owner of it and traded the gun for two 270 Winchester rifles, he told me he traded it because his eyesight.
I started at 25 yards, then 50 yards and it was close to being dead on and at a hundred yards i had to cut the 6 inch circle aiming high.
