Well.. the first shot from a clean barrel was kinda by itself. What i expected was for the first and second shots to be together, and for the following shots to be in a group of their own. Not so. The rifle was an Omega X7 with a 1X Nikon scope mounted. The load was 300g Deep Curl, 110g Blackhorn powder, crush rib sabot, Federal 215 primer.
As i drove home i pondered what to do. Immediately vetoed was to hunt with a fouled barrel. Then i thought about popping a few primers before the rifle was loaded. Since i have taken to using rifle primers, because they are quite clean, and because they cause zero wear to the flash hole, i realized this would be kinda useless. So.. i thought well i will just install a breech plug that utilizes a shotgun primer first, and pop some shotgun primers. Then the thought struck about how shotgun primers foul the flame channel so. Then i wondered if there was an old breech plug laying around that had a vent liner installed. It seemed to me if the shotgun primers were popped in a breech plug without a vent liner in place, more fouling would reach the barrel.
After the rifle was cleaned, the vent liner was removed from an old breech plug, and the plug was installed into the rifle. A shotgun primer was popped.. holy smokes it was deafening in the garage, and there was lots of , soot, and flame that came out the barrel. Two more primers were popped, with hearing protection in place. The flash hole seems to hold back a lot of fire, and sound. The old plug was removed from the rifle, and the plug set up for rifle primers installed.
Using the same load the following target was punched.
Every shot just got higher, and higher, but the first shot kinda wasn't so alone this time. Kinda seemed popping the shotgun primers in the breech plug without a vent liner installed worked. Well, i figured i should have waited some between shots, so i had to redo everything.. the rifle had to be cleaned, and the shotgun primers popped without a vent liner in place.
Then i tried shooting another target, however this time i waited and waited between shots. The results were pleasing to me.
Then a move was made out to 100 yard, and 5 shots taken, and i really really wanted to turn up the power dial, but alas it wasn't there. Aiming was difficult because the cross hair of the 1X scope completely hides the red circle.
It seems the primer fouling from a breech plug with a large large flash hole kinda replicates powder fouling, however it isn't corrosive.
