Interesting...

One of the issues I have now is: Of all the varieties I've tried the slugs are crossing with my 12 gauge double. Indeed it seems some shoot farther apart than others, yet, the faster slugs don't seem to be shooting farther. It seems more like by type.

I shot some winchester 1600 fps slugs this weekend and they were a bit less than 2 inches left or right of aim point. (Crossed). And low.

Then, of course, I just compensated and tried to HIT the bulls-eye. One of the problems with shooting .720+ sized projectiles is the bulls-eye doesn't last much more than 4 or 5 shots before you blast it away and it loses its efficacy. So you have to trudge all the way out there (through the snow) to replace the target. Oh the many hardships of shooting big bores, hahahaha!

I hear you about a chrono. My efforts would be better served with one.

I would like to cast up some of those round balls in .724 diameter (for bores of that size) and get them flinging at 1700+ fps. The trick is getting them to hit POA. Theroetically, since 1700 fps is faster than the slugs I've been shooting by 100-200 fps the 1700fps slugs should shoot even FARTHER apart, and even lower than the current 1500-1600 fps slugs I've tested. Theoretically.

We'll just have to see what they do. I'd hate to have to load the slugs up at 1400 fps or slower to get them NOT to cross. That would not be satisfactory for me.
