I can't tell you base to ojive...don't have a tool. BUT ....base to tip (true OAL) is 4.09.
what is everyone's OAL from base to OGIVE with a 300 gr, berger, THANK'S gun)
DEWAYNE,
This dimension will probably do you no good because there are probably a lot of different freebore differences. You will have to find the touch point yourself. Somebody elses dimensions could put you 30 thousandths in the rifling to maybe 30 off.
This is a measurement you need to determine for your rifle. Get one of these....
Hornady Lock-N-Load Overall Length Gage Bolt Action
It will help.
color the tip of a dummy round (loaded long) and gently insert it into the chamber (if you go to hard the bullet will get stuck in the bore). the rifle will set the bullet to the land and the felt marker will tell you where the bullet is contacting the lands.
Very hillbilly way of doing it but it works for me.
