Armscore 147gr fmj-bt

[Chasefriess419]

So I just ordered 1000 147gn fmj-bt projectiles from surplus ammo (armscore) I was looking through my reloading manuals and couldn't find any info on these for 300 aac. I have the Speer
15th book, Hornady 10th book and Lyman 50th book and all of them have 150gr projectiles in there. Hornady and Lyman both offer a fmj-bt but Speer only has the gold dot and soft point projectiles to choose from. I hate assuming when it comes to reloading as I don't want to blow myself up, but would it be safe to use these data references for the 147gn?

I use H110 powder
WSR primers
Trim length of 1.365
Shooting out of a 8inch barrel with a 1:8 twist.


The Hornady book for 150gn fmj-bt calls for:
12.3gn-15.9gn of H110 with 15.9 being max load.

The Lyman book calls for:
14.5gn - 16.2gn of H110 with 16.2 being max load.


Both books are for the exact same projectile.


If anyone has any advice I would appreciate it.

I think following book starting charges for a 150gn FMJ will work fine with the 147gn. As long as the projectile shape/length is comparable. You wouldn't want to load a tracer for instance with load data for a hot fmj because usually the tracer projectile is way longer then a normal FMJ and when you crunch more projectile in the case you can raise pressures to a a point you don't want to shoot a 2nd one.

You will probably be able to work up to a decent velocity with the 147fmj's. If I get back out to the shop, I will check my notes for some load data.
