Group analysis 375 H&H

[FOTIS]

Ok fellas this is my SAKO 375 H&H Finnbear. The load is
75 gr Leverevolution with the 250 TTSX
Velocity is 2840 fps. 3.600" COAL

As you can see she "wants" to shoot, and to some this might be an acceptable hunting group, but not for me. Not because I am special, just anal!
Anyway I am thinking deeper seating. It sits at 3.6" so seat in...... in what increments?

Any other suggestions? What say you?

I'd try seating deeper .020" and then another .010" to walk them in.
I ended up going the other way, 3.610"

I'd be happy with that!

I usually go .025 at a rip till it’s close.

Thanks Scott~

Barnes listed coal for that is 3.590

As a rule of thumb i always start 10k below the listed coal of any bullet unless specifically noted otherwise.

Try your next group at 3.580 and see what happens

I dunno Fotis... Am thinking you might have shot that target with a double-barrel gun...

I like the idea of seating the bullet a bit deeper to see if the group will tighten up.

We will see this weekend pending on the gale winds.

I know my 375 Wby is a wee-bit different but it loves the 250gr TTSX. I had mine throated longer than the 3/8” factory length. So maybe shortening them up might help. I’m running them also at 3.600”.
Your double group might be more mechanical than the load. Free floated barrel?

 

[FOTIS]

Yes bedded and free floated trijicon scope.

I just went downstairs and took the 375 all apart The bedding looks impeccable
