I believe you are actually shooting the 32 FN, as I don't recall ever making an LFN that short, and won't.
Try sizing them larger, so long as they slide into the chamber easily. That little bullet shoots tight groups in any 30 caliber rifle I've ever tried it in, going fast or slow.
If you start them at 1400 fps it will kill small game instantly with a half inch hole through and almost no meat loss if you don't hit a large bone, in which case the bone will become a secondary projectile far more violent than the bullet.
At 1800 fps it will kill deer quick and clean with good hits out to 100 yards or so. With the load you have it will really clean their clock, but slow them down to not over 2400 fps if using water quenched ww alloy, and intending to shoot in sub 0 temperatures. Real cold cast bullets with a hardness over 20 can turn to powder on impact in extreme cold with high velocity impact. In other words, starting them at 3000 fps is no problem if you never shoot anything in close enough that remaining velocity, or impact velocity, is over about 2400 fps.
