Some time ago i modified the powder end of my Accura breech plug so that it looks more like the Omega breech plug. This was done, because when using BH209 and W209, i had experienced a very few hang fires and one no fire whilst preparing for last hunting season.
Sabotloader provided information on installing a vent liner, and i was able to get the job done.
The deeper concavity that was introduced seems to help; since making the modification there have been zero ignition problems. However, after firing the rifle so many times the primer seat started to erode, and this flame cutting became worse and worse with use. To fix this issue, i utilized information provided by
Busta, and prepared the plug to use o-ring under the primer.
The o-ring totally eliminates all blow back, and cured the flame cutting of the primer seat.
Yesterday, went up into the hills to shoot the rifle off a walking stick, to practice for this next hunting season. I thought i could test whether a 777 primer would ignite BH209 with this breech plug, but i couldn't find any of them around the house, so i figured i would just try some vara-flame chingadero with small rifle primer. The rifle wouldn't light the primers at all. This, for some reason, disturbed me. When i came home, i decided to use information provided by
Screwbolts and modify the primer seat with a grade 8 bolt. The grade 8 bolt allows one to redo the primer seat, and eliminate the o-ring. Before i could finish, wife wanted to drink beer, so i quit working on the breech plug.
During the night while we were sleeping, and i was dreaming of breech plug this fella walked through the back yard.
This morning i finished the breech plug.
After finishing the breech plug i went up into the hills and shot the rifle several times. First thing, i tried the vara-flame adapters, and experienced a hang fire, and 2 no fires. The rifle did ignite the primers today, but the small rifle primers weren't so very good at igniting BH209. Then, what with the hang fire, and the no fires, i started to flinch. That was the end of that, and i went to using the Winchester shot gun primers, after i kinda cured the flinch. The W209 were once again 100% reliable.
