This forum is killing me. I've never found so much useful info condensed into such a small space!! Even as I type this I should be out in the shop loading and at my range shooting! But, here I am again....whiling the time away reading posts here!
Anyhow, I've been shooting a nice little NEI 155 gr. PB bullet and getting pretty good accuracy in my K-31. I've also shot jillions of the 314299 GC and likewise obtained good accuracy. But I began wondering: which is the most accurate design?
I've pored over the results here from the various matches and it seems the GC design is almost universally used by competitors. I understand that we can buy really high quality moulds, carefully control our casting methods, and weight sort our bullets in order to obtain the most accurate bullet and loads. But, we have no control over the consistency of the gas check which to me seems to be the weak link in the accuracy chain where a gas check bullet is concerned. With a PB bullet, it would seem we eliminate the variable of the check and are totally reliant on the bullet itself.
But again, everyone here seems to use a GC design for competition. Why? Is it because the GC design is necessary for the desired velocities, or is it because the GC type bullet is typically more accurate than a PB design?
I really want to get more into shooting High Power competition and do so with 100% cast bullets, and I'm mulling over the possibility of having a custom mould made, probably for my K-31, and would of course have to decide between PB and GC design.
