Velocity

[Savage76]

I have a Truetimber Camo Savage axis in 308 22" barrel
My father-in-law loaded 55g of IMR 4064 and Hornady SST 150GR tips does anyone know what kind of velocity that gets

Only way to know for sure is to shoot it over a chronograph.
I would guesstimate somewhere in the 2500 - 2600 fps range, tho. But don't take my word for it.

According to my sources 47.7 gr is a max load. I don't think it would be possible to get 55 gr in a 308 case. Are you sure? I bet it was 45 gr.

The starting load is 43 gr @ about 2660 fps. The max load of 47.7 should be about 2900. But those are from longer test barrels. In real world guns with a normal length barrel, you can take 50-100 fps off those numbers. My best guess for 45 gr of powder would be 2700 fps.

But no 2 barrels are the same. You might get 2600 fps, and my rifle with the same 22" barrel might get 2700 fps.

According to the Hodgdon website, you're in uncharted territory. Their max load is list as 47.7C (compressed).

Yours seems like a hot load to me.

According to the Hodgdon website, their barrel length for the 308 Win load above was 24" inches with a 1:12 twist and a trim length of 2.005".

Either you have something mixed up or your FIL doesn't like you. Verify your load and report back.

G-d didn't give us inertial bullet pullers just for grins, you know.

According to Hornady, maker of the bullet, their max is 44.9 giving a velocity of 2700fps from a 22" barrel. Like others here, I'm hoping the OP misunderstood his FIL.......

My main reloading manual says start load is 42.3gr with a velocity around 2682. Max load listed is 45gr at 2840fps. Even in my Speer manual that usually shows hotter stuff puts start load at 43gr and 2533fps to a max of 47.0C and 2814. Once you start compressing loads that is the case's way of telling you to stop. A 308Win case only has a capacity of 3.43CC and 55gr of any powder is not feasible. Even H414. Check your FIL numbers again before doing anything else.
