223 OAL

[BobLeeSwagger223]

Where do you guys seem to have the best luck with OAL?? The usual trend seems to be the closer the bullet is to the lands the better. I COMPLETELY understand that no 2 rifles are the same! I'm just wondering how close, or far away you have the best luck.

I'm working on an 8 twist 223 currently.

Mine really like to be about 10 thou off the lands. seems to work most excellent for me

 

[Tozguy]

Ten thou for me too and happy

I have had 788's, 700's, and customs with zero freebore. All of them shot very small groups less than 1/3" with the bullet just barely touching the lands. As the leade grew, groups would still hover in the 5/8" range as the bullet jumped .050 or so. The poly tip bullet groups would open up more than a std Sierra Sp due to less bearing surface.

None of the 22's that I had would shoot bug holes with bullets jamming the lands .003 or more.

Depends on the bullet being used and your chamber dimensions

how do you find out when your bullet is touching the riffling, if i don't hace a guage..i tried putting a bullet in a casing and make it black to see if it was,, but that didn't work,,

It's pretty well made and an excellent tool to have handy! You do need to get a modified case for each cartridge.

I get best results from my .223 when my Hornady 68gr BTHPs are just barely touching the lands.

;D Don't know! The neck an throat is so long on my factory 223 I have yet to find a bullet that will stay in the case when it touches the lands!! They all fall out!! ;D

Low runout is key for me, outside turning and bullet runout of less than .002 still gives me sub moa out too 300, I'm quite content with that.
I trim the cases a bit long and seat to a minimum with proper tension.
It's all I can do, but again proper seating with low runout seems be the magic.
