Long throated 308's

[broncman]

Anyone with throats setup for 215 weight range ever step back down and shoot lighter bullets like the Juggernaut 185's?

My rifle is throated for the 215 berger hybrids so that bullet base us above the doughnut. This puts the 185's up in the neck a bit. I have more Juggernauts on hand than the 215 so I loaded some up to process my new brass.
WOW! I shot my best ever 5 shot 308 group at 100 yards! somewhere in the low .300's. May load up more to see if it was a fluke.

Anyway, I had to use more powder than my standard load since the bullet was seated so far out. No pressure signs at all.

Have any of you ran the lighter juggernauts seated long and got more speed with the increased powder charge? My speed for those 5 was about 2755 and primers were not showing any signs at all. Wondering if I can get more speed and keep the accuracy. This would close the edge the 215's have and not have to deal with their recoil.

My 215 load is very promising but not very forgiving in any gun handling mistakes at all!

In my new gun with the barrel setup for the 230s the juggernauts shoot very good jumping a mile. When i was doing barrel break in i shot a 10 shot group off the bipod that measured in the .4s at 100 yards. I just loaded 43 gr of N-150 and jumped them .110 for no particular reason, zero load developement. Just wanting to run some rounds down the barrel so i just picked a charge that i thought wouldn't be too hot and it shot lights out. No idea what the speed was but with that powder charge im thinking it was in the 2600 ish ftps range. My barrel is 30 inches.

What is the lenght of the throat in your rifles?

Not sure. I do know the length to the lands and seated on the lands, a 215 berger hybrid bearing base is about 60 thou above the neck junction. I sent dummy rds to Shilen to throat the barrel for the 215

I shoot 230 Hybrids in both .308 and .300 WSM. My reamers have .280" freebores. That allows up to ~.030" jump from touching without seating to the neck/shoulder junction.
