RE: Homework---partially complete Barnes FlatNose
Cayugad, the ventliner is basically a replacable flash hole. Instead of buying a new breechplug every couple hundred rounds, just unscrew the oldventliner from the breechplug and screw in the new one. It's pretty much just a allen screw with a .031 hole drilled through the center. Good idea, and much cheaper than a new breech plug. Mine only seem to last about 75 shots before it starts opening up a little and accuracy starts going away fast, but its a quick fix and only cost a few bucks. (probably only costs cents to make)
Chap, nice shooting. I look foward to hearing the final results with these two bullets.
