Load data for nosler 170 solid base 30/06

If you are that close & concerned about it you might be better off measuring to the ogive rather than OAL when copying the length of a different bullet type.

Hi Gixer try finding the lands with an empty case and bullet head squeeze the neck a little to hold the head in place .seat the bullet over length and chamber it to find the lands the bullet should slide in the neck when it makes contact with the lands do this 3 or 4 times measuring the lenght each time they should be the same the seat your loaded bullets 15 thou deeper than this.15thou is a common depth to start with for bullet seating.develope your load now and then play with the depth in or out 5 thou.
regards NigDonn.

Measure the length of your bullet, tip to base.

Add 2.109"

Seat the bullet to this OAL and the base of the bullet will be level with the case-neck junction, which is ideal.

Seat any deeper and the bullet will intrude into the powder space, which could raise pressures.

This is why Lee state a minimum OAL for their "never exceed" load data. I already told you this OAL for 168gn bullets, but your bullet may or may not bear any resemblance to theirs. Soft point, hollow point, ballistic tip etc. all make big differences to bullet length. Nevertheless take note of this OAL, as a reality check.

Seat any further out, and the bullet will not be fully gripped by the neck.

Now test to see if this OAL is suitable for your rifle. Make up a slightly long dummy round, seated to this length, plus 20/1000"

Try chambering this in your rifle. If the bolt closes cleanly, and the ejected dummy does not show any engraving of the bullet tip by the rifling, it fits in the magazine and feeds cleanly, then you are good to go.

​Seat bullets to the calculated value, without the extra 20/1000"

If the dummy is too long, re-seat the bullet deeper, 10/1000" at a time, until it fits. Subtract another 20/1000" and
use this as your OAL.

Ignore the position of the cannelure, it is irrelevant, unless you need it for crimping.
