Sorry to resurrect a somewhat old thread , but l didn't wanna make a new thread unnecessarily. Does anyone know the Barrel life of a .375 H&H Winchester Model 70 ? I have a pre war model which which my great granddad got in '38 or '39 and passed it on to my Granddad , who gifted it to me. It's fired over a thousand rounds ( from Kynoch round nose 300 grain solids in my Grandfather's days to Norma modern loads ) . It works as accurate as ever . Has anyone here actually shot out the barrel of their .375 Model 70 ? I was reading Finn Aagard's son's online article which implied that Finn's model 70 in .375 needed a barrel change after 2000 shots.

suspect that if it did it was not from erosion caused by shooting.
308 palma rifles get over 3000 rounds easily, and they would erode faster than a 375.
higher pressures, higher rate of fire, higher string counts when hot, and so on.
and that is for serious target accuracy.

Thanks Bruce . It shoots 3 inch groups at 100 yards. I am guessing that's an okay thing for a cape buffalo.

Hoss, 3” groups depending on the bullet should kill any buffalo out there.
That said, I’m a varmint hunter and mentally I cannot have any load I use in the field shoot more than 1” groups at 100 yards. It’s an illness I have:cry:!

Are you doing three-inches with open sights or a scope?

Red Leg , Iron Sights for myself. But my wife occasionally uses my rifle ... Then l attach a scope. The 3 inch grouping is virtually the same with both iron sights and scope. I use Norma and Federal Ammunition . I recently ordered some Kynoch 300 grain round nosed solids , just for the nostalgia factor ( l read so many old books about the old elephant hunters using these rounds and also this is what my granddad used in '68 to take his elephant ) . I will try them out when they come .

You're a perfectionist ! I used to own an old model Savage Model 99 in .22 Hi-Power ( which l foolishly sold shortly after getting my .375 ) . The gun was my VERY first Hunting rifle. It was a tack driver of a gun ( not something you typically expect from a lever action ). Back then , you could legally use a .22 Centre fire in Maine to take deer ( maybe you still can . I haven't done it in years , so l don't know ) , and l used mine to take some pretty big critters ! I always opted for the neck shot and the old Savage always delivered. But one day , l made a rash decision to sell it , after l nearly lost a buck with it while trying a heart shot. It's something l still regret to this day. Accurate little gun .

A pre-64 model 70 ought to give you 1.5 inch groups with a load it likes. I am sure you know that pre-64’s in general can have considerable collector value - a .375 especially. So be very conservative doing any “tweaking “ of that rifle.

With respect to accuracy, I’m pretty much MOA fixated as well. Out to 100 yards you will be ok with a 3 MOA .375. Beyond that, “threading a bullet” through cover becomes problematic. And of course, you likely will be hunting things besides buff. I would take my time and find a load it likes.

Red Leg , thanks for the useful advice . In regards to tweaking , I'm afraid you're 40 years too late ! During my Granddad's time , the stock split and he used some sort of strong adhesive and ( what l believe to be ) car door bolts to repair the stock and hold it together. He also smoothened the feed ramp so that it could feed certain types of ammo. My model 70 holds 4 in the magazine , unlike the modern model 70s which have a 3 round magazine and allow you to have one extra round in the chamber. But my model 70 can't be topped off with a 5th round in the chamber . A gunsmith once told me that he could try " opening up the extractors to allow the gun to be topped off with a fifth round " but l immediately refused.

I have a like new VC .450 I might part with. I had it built in 2013 and it has served me well. Also have a VC fitted leather trunk case for it along with the plastic case it came with. I'll take 14000 for all of it.

Hi Jody,
I have been looking for ideas on the best way to display my European mounts from Africa. I came across some of your shield work and was wondering if you would be willing to make one for me? If so, please let me know the cost. I like the shield with the two spears that you built for a member years ago. Thanks.
