I am having a bit of trouble working up a good load for my son's Savage Model 11 .308. This Savage seems to have a deep chamber (distance to lands). In my other rifles, I set my overall length such that the bullet is 20-30 thousandths off the lands and get great accuracy. With the Savage, the lands are really deep. I need some advice on how to best set overall length for this rifle. Here are some numbers:
Measurements made with Hornady Lock-N-Load Overall Length Gauge and bullet comparators.
.308 Remington Brass
Case Length: 2.0075
Neck Length: 0.2630
Hornady 150gr SST
Bullet Length: 1.2020
Bullet Ogive Length: 0.5855
COAL: 2.8785 measured
Case Ogive Length: 2.2534
Given 0.030" off lands, COAL is 2.8485 : 2.7350 Hornady book
Sierra 150gr SPT Game King
Bullet Length: 1.0975
Bullet Ogive Length: 0.5390
COAL: 2.8505 measured
Case Ogive Length: 2.2979
Given 0.030" off lands, COAL is 2.8205 : 2.705 Sierra book
Note that the Hornady seems better suited for this rifle because of the location of the ogive. Even so, it would need to be set almost 0.10" deeper which makes a big jump to the lands. I have tried loading to book specs but accuracy is just not there. Any thoughts? Thanks all.
