HI all, new to forum (first ever forum as a member and one of few I was ever interested in doing more than just reading from).
Thought Id like to hear from anyone about the need to to use gas checks on light loads, with light bullets, in 348 winchester. Id like to avoid them if they aren't necessary.
Thanks

I have absolute confidence that you will get good performance from gas checked design bullets shooting without the gas check if velocity does not exceed about 1500 fps and your alloy hardness is mated to the velocity/chamber pressures you are loading to.
Somewhere here on this forum a few years ago we had a thread about this very subject of shooting bullets designed for gas checks without the gas checks. I think there was enough evidence presented by several people to come to some definite conclusions.
I am not sure what sub forum it is in but should not be hard to find.

Also new to the forum. This is good advice on velocity.
I will continue to use non-GC bullets in my 45-70 rifles, and 450 Alaskan Model 71.
Straight wall cases handle plain base bullets well-considering velocity and bullet alloy.

Good morning
We also shoot non-gas checked cast until our mix decides to tell us we need a stronger base. In straight wall cases we will first add a cereal box wad which will normally clean up minor lead wash on a marginal load.
For hunting loads we start with a GC generally if we know 1500fps + is the goal. We use 50-50 (WW-range scrap) for most hunting as we want expansion with our heavy for caliber cast for complete pass through of a large for caliber exit hole.
