problems with gas checks

[Blammer]

If your shooting a GC bullet with out GC at medium velocity, is there any real problem that could occur?

That is one of them...you have to consult professor gun deals....I have had great luck and bad luck...it just depends.

Worse case, they shoot erratically, and lead the bore a bit.

Best case they shoot good and you save gas check money...

If the boolit is hard enough and fits the throats, you can shoot them as fast as the gas checked boolit. Try them out. The worst thing that can happen is accuracy will be bad if your rifling needs the drive band length lost by leaving off the check.

you might get it to work but its never given gilt edged accuracy for me. In the big picture what your shooting isnt alot different then a bevel based bullet.

just getting impatient on waiting for my gas checks and wanted to shoot some with out, just to get shooting!

Lloyd says it right! A bevel base is lacking drive band length. Never seen much use for the things myself. It is amazing how a little more or less drive band area can effect accuracy. Those that sell bevel base boolits don't allow for it by making the boolit longer and heavier. Lee makes a .357 boolit mold with a bevel base. First thing I did was remove it. It shoots much better. A bevel base boolit of a certain weight will shoot like a much lighter boolit. If the twist won't support a light boolit, it won't like the bevel base either. Just blasting at 20 yd targets won't show much difference but if you want extreme accuracy, pay attention to the twist rate, boolit match. I have had accuracy at 100 yd's that would hit a nickel every shot but leaving off the check would make every boolit key hole at 50 yd's. This was a 30-30 TC with a scope. The slight loss of the drive band had enormous effect.
If you are shooting too heavy of a boolit for the twist and accuracy is poor, leaving off the check might make it a shooter. BUT, most guns will handle a heavier boolit OK. The worst case is a boolit too short to start with. Leaving the check off aggravates any problems as does making it a bevel base.
