Hey guys, just wondering where you guys like to seat your bullets. I'm getting ready to load my first rounds and I was thinking I would start at .010" off the rifling. Anything from touching to .030" seems to be pretty common. My rifle is a 10ba. I'll be shooting 185 juggernauts. Anyone know the maximum magazine overall cartridge length I can go on the 10 ba? I'm pretty sure I have plenty of room to stick my bullets out a little
i just started seating my rounds out, but my best was .010 off lands. Surprisingly to me at least my next best was .025 off lands. Going to the range tomorrow to shoot a little and see what my cousins' rifle likes. He will be shooting the prettiest brass I have loaded I forgot they were tumbling this morning until this afternoon when I went out to load them.
I am at a min .050 up to one hundred as you can see I like to jump the lands.

So do you guys just choose a distance and then do a ladder test with powder charges, then choose another distance and do the same thing? Or do you choose a distance, find your most accurate powder charge, then play with the jump? Seems like I could burn through an awful lot of components finding that "perfect" load.
That one if the ladder test result show enough promise. I have ended up as far as .050 " out as well.Quote:

In my 308 Berger 155g hybrids 0.118 off the lands, yes that far. And screaming fast. But it bug holes there. The 22-250 likes the 80g at 0.046

I didn't get to chrono them the other day but I was up 33 clicks at 500 and shooting a foot over the target. My math puts me at 3200 with 45 grains of VARGET if I remember correctly. Only a slight ejector mark on the brass and shot a 5 round under 2"Quote:
