Bedding- it does make a difference!!

[bubbapug1]

Well folks the mystery is over. I put match lines on the ring/scope interface and blasted away. Sure enough the scope moved. Not every shot, more like every third shot. I loaded up some 2800 fps loads and tried those. The gun held its zero and shot a 1.5" 5 round group.

Problem almost solved.

Maybe it's time to buy a ring lapping kit. I had leupold rings at first and switched to some swfa rings. I can't see the leupold rings working with such heavy recoil. I put in weaver 71 mounts with the swfa rings.

Is there any way to add to the ring friction to get me back to the 3000 fps loads?

Powdered resin......

Powdered resin......

What about bedding the scope to insure a 100% fit while mounted in the rings, than the use of the powdered resin to add friction?? The 375 really packs a wallop. This is an issue I have never run up against, even with a 50 bmg...but that has a muzzle brake.

Contact Alaska Arms to see if their rings will work.

They 9ffer to custom their rings to other Mauser Actions

Unless you are the worlds worse shot, there is something really wrong with that gun. A smooth bore musket might shoot just as well. Something big is wrong.

Hey now, a good smooth bore will shoot much better than 8 inches...

I am not sure about your particular situation, but over the years I have experienced guns that just don't shoot worth a darn. I could never figure out what was wrong with the guns (rifles and pistols). Sometimes an old pitted WWII rifle (Mauser) would shoot better groups than a brand spankin new bolt action gun. I have also seen rusted pitted 70 year old S&W Model 27 revolvers with bad timing shoot better than brand new S&W revolvers with a tight cylinder.

I have a Springfield 1911 in 9mm which started shooting bad groups. Like 5" at 10 yards. Sent it back to Springfield. They recrowned the barrel and put new night sights on it. I got it back and it still shot BADLY UNTIL I RAN OUTA my reloads with plated bullets. Put 9 Winchester white box in a 1" group the next mag. God was I embarrassed. I called Springfield and tried to pay for the work and sights. They refused and thanked me for buying from them.

I was pushing the extreme bullets too fast. I always try to check the bullets first before I assume a gun is a POS. I'll try twovof three different brands. With the 375 it hurts doing that but it's a must.

I had same issue. tried everything, scopes, mounts, what not.
The problem was in the barrel. It touched the forend. As soon as i relieved it my group became subMOA. I made a postcard to pass all the way to receiver, not only a $ bill

TheReels are fixes for that.

A full / force bedding being one of them.

Bed it to keep the stock from cracking. A 375 that get any kind of run in the stock is going to crack sooner or later, especially if it has the typical Mauser rear pillar in the stock.

Got it working!!

[BrocLuno]

Whatever it takes. It fixed this one. That's all you need.

I am a bedding fan. Never had one that bad, but it always seems to help mine

[ar15barrels]

Got it working!!

Post number two still perfectly answers post number one.

Thanks Randall. I read it again and it makes sense.

You can see from the thickness of the bedding from the recoil lug forward the gun was never really supported anywhere in front of the trigger block. The bottom of the recoil lug was not touching the stock. The whole front of the action and barrel were resting on the front of the stock with nothing underneath to reduce sag and tension. The assembly was heldin place in a bowed state by one bolt. No wonder it acted squirrelly!! Now it's cozy in a pair of epoxy socks.
