That is a pretty good question.
Most times 99% of the time when developing loads we will use SAAMI OACL.
There are times we will seat the bullet as follows:
To determine the best seating depth for your individual gun you will need:
1. A cartridge case that has been fired in your gun, and not...
RL-19 is great powder for 300 WSM and the 180 FS.
With Fail Safe you need to use the min. load
This is due to the internal construction differences.
RL-19 MIN LOAD 63.0grains
RL-22 MIN LOAD 65.0grains
We don't many 9.3 seconds.
We have the .270-130BTs right now.
As for our QC, it is getting better everytime we run something. I would anticipate the 6.5's shortly, we have the partitions in stock and the 100gr BT, just no 120's.
In the latest Rifle Magazine Chub Eastman wrote about seating the AB in the 300 WSM. Great article.
Won't hurt performance, and yes you can use Partition data.http://www.riflemagazine.com/magazine/article.cfm?tocid=1585&magid=107
Especially in those heavy weights, the AB will hold together. I shot numerous game the last 2 years with it. In fact we did a test on Hogs in Texas, shot one at about 10 feet (Texas Heart Shot) Found it in the skull.
The major difference is the lubalox coating. The minor difference is the tip color...
The 168grain BST is a favorite for Winchester and is a hot seller.
For the .338 Win Mag 225gr PT
IMR 4350
Max 71.5grains =2882fps
Min 67.5grains= 2733fps
RL-19
Max 72.5grains=2832fps
Min 68.5grains=2669fps
H4831SC
Max 75.0grains=2810fps
Min 71.0grains=2692fps
These powders will give you the velocity to assure proper expansion and energy at 400yards...
They have been changed a few times since the 1990's. Mostly in the jacket thickness. They are still designed to be shot at impact velocities of 3000fps or less.
Accurate Arms Powder has some data as well. We currently don't have data for this cartridge.
