View Full Version : Which load data to use?

The bullet in the middle is the bullet in question. I know EXACTLY what it is, so please keep that part quiet. If you know what it is, great. :D

They are between 160gr and 165gr. Due to the longer length, I'm not sure if I can safely use the 165gr data from Lyman #47, or if I should use 175gr data that I got from Hodgdon's web site, or the 180gr data from Lyman #47.
I have 8# of BL-C(2) that I will use to load these with once fired mil brass and CCI #34 primers.

Which data should I use, or where should I start?

-- graphic removed --

Top: M80 (for ref.)
Middle: The bullet in question is 1.375" long pulled from 30-06
Bottom: M2 (for ref.)

Hodgen Data Manual # 26

Using GI cases

168~172gr bullet = 41.0gr BL-C(2) starting load
180gr bullet = 40.0gr BL-C(2) starting load

Based on this info, I would go with the 40.0 and work up from there. I tend to lean heavily on the cautious side.

Used to use a lot of BL-C a while back and liked it a lot. I'd grab some now if the price was right.

Thakns. I'll start at 40gr, and look for high pressure signs.

I saw your picture earlier today. Of concern to me, is the long bearing surface. Long bearing surface means more friction and higher pressures. Substituting data for a bullet of similar weight may not work.

I think Barnes-X solid bullets are long for their weight, you might want to take a look at load data for those bullets before you commit to a charge.

I would try them in a strong bolt action before shooting from an FAL just to make sure pressure limits are safe before subjecting a gas system to potential abuse.

I have not found this to be a significant problem

The CCI #34s are considered to be magnum primers. Why did you delete the pic?
