Winchester model 70 375 H&H Accuracy

[az2tx]

Check your action screws torque as well.

this would be the first thing i would do
2nd is male sure it isn't the shooter
3rd make sure the bore is clean from being a brand new gun

That 525i is a piece of junk. :-) I'll take it off your hands.

Seriously odd. If you have a bore-scope take look and see if something is obvious. I have 4 .375s and all of them shoot MOA or very close with almost anything I feed them (270 or 300 gr.).

With everything you have already checked I would be inclined to think it is a bad barrel or terrible factory bedding. Are you noticing any difference with the first shots? Are they more accurate than subsequent shots? Have you tried shooting once and letting the gun sit between shots to see if that tightens things up at least some? Any chance the forearm is warped?

What torque values did you set it all at? Did you push the action forward in the stock before tightening? If not bedded, it can move forward under heavy recoil.

Man, a .458 Lott owner talking about heavy recoil from a .375 H&H. What is this world coming to? I know, women, kids and wormy men who handle the H&H like it is a .308.

I have a Winchester Model 70 in 375 H&H that was made in 1965. I reload Barnes TSX in it and it will cloverleaf 3 rounds at 100 yards. And, mine also carries an older Leupold Vari-x IIc 3-9.

There are so many things already mentioned above that could be your problem but before I spent a dime on it taking it to a gunsmith, I would send it back to Winchester. You have already eliminated it being a scope issue so it is definitely their problem from what you have said.

Hopefully you took photos of your groups, ammunition used etc. so you can give them plenty of information to work from. If you have to pillar bed and free float the barrel on a brand new rifle I would be sending it back for sure. Good luck, I will be interested to see how it all works out.

That is good advice

Haha. You know what I mean!

Any resolution here?

Following, this seems interesting.

The action should be pushed to back, the front of the recoil lug is normally not bedded to aid in removal from the stock. The barreled actions movement is rearward during recoil, so you want it snug to the rear against the stock lug recess before tightening action screws. Scope on a picatinny/weaver type rail, you want pushed forward before tightening.

One more little tiny tidbit. Do not have the front sling swivel resting on anything when you shoot. Be sure the forearm is resting about mid point on whatever your front rest is. The devil is in the details.

First thing I'd do is try a different shooter.

Correct. Thinking backwards. Good catch

[Buzzsaw]

agree, let someone else shoot it

Then bedding and new trigger, the Winny MOA triggers are crap.

then shoot it with a towel between but and shoulder

We are ALL great marksman and never jerk a trigger in anticipation of recoil

except me. I bought a beautiful 1992 Model 70 Super Grade in 7mm Magnum and I know I was jerking the trigger.

It's going to the gunsmith tomorrow for bedding and a Timney 1.5# trigger to match my other rifles trigger pull

Then practice for killing a Nilgai next year

In for the solution
