I've got a 375 H&H that I'm looking for some help with. It's a Remington 700 XCR. I'm a thumbhole stock guy, so I put on a Boyds thumbhole laminate. I've glass bedded the action tightly and tuned the trigger down to about 3.25 lbs.
So far I've been completely unable to get this rifle to shoot. It's giving my 3-5" groups at 100 yards regardless of the loads I feed it. I was careful to break in the barrel correctly when it was new. And I tried fully bedding the barrel and then removing the bedding to free float it. That doesn't seem to have made any difference.
I did find something out this evening that kind of irked me. I broke out my Sinclair tool for calculating overall cartridge length. With a Sierra 300gr bullet I would have to seat it out to 3.785" to get the bullet touching the lands. (Standard max OAL for the 375 is 3.6".) Now, I understand that rifle manufacturers want to give us a little freebore to save us from ourselves. But .185"??? It would be nice if the bullet and the lands started in the same frickin' county for Christ's sake! That's coming up on 1/5 of an inch of freebore.
Naturally I can't seat my bullets anywhere near the lands and still have them fit in the magazine. I can't imagine that such a big jump is helping my accuracy any. And I'm really looking to find out what the culprit is. I would expect an off the shelf 700 with a tightly bedded action to shoot more in the 1-1.5" range at 100 yards.
What do you think, is it worth taking this rifle to my gunsmith and having him turn the barrel in to get my freebore down? Do you agree that so much freebore is likely a problem? I think I've done all I can with the bedding. I'll probably put a Shilen trigger on it, mostly because I don't like the feel of the stock one. But I wouldn't think that would make that much difference.
By the way, does anyone know what the standard freebore was on a 375 H&H back before guns were designed by lawyers? It's not a high-pressure round like the Weatherby's, so I wouldn't think it would need that much.
Thanks,
Ben
