I was wondering if you could do a straight forward re-chamber of a 30-'06 Ackley Improved to 300 H&H? I know that there would have to be some action work.
Thanks for any help.

How long is the barrel now? Keep in mind that the bolt face and magazine need a lot of work.

It's a lot easier to just look for a 300 H&H for sale.

Don't let anyone fool you..

going to 300 win or 30-338/308 norma is EASY and fast..

but, unless you've got a LONG action, there's $$$, time and $$$ to go 300 HH

I did my 30-06 to 300 winnie about 10 years ago... bolt face, chamber, feeding, 8.25# 300 winnie in 2.5 hours

I don't have the data in front of me, but with the taper of the H & H case, and the sharp, expanded shoulder of the Ackley, I suspect that the old Ackley chamber may be already too large at the shoulder to clean up properly for the H & H without set back.

Thanks for the replies as stonecreek hit my worries on the head. It is very, very close fit from the case drawings I am looking at.
I already have a 300 Win, and a 308 Norma. I just picked up this barrel for a muaser 98. My plans are to build two rifles one in 375 H&H, and another in 300 H&H. I know that people don't like to put the H&H's in a standard mauser, but if done right (i.e. using Blackburn bottom metal and taking most the metal from the rear of the magazine well) it can be done.

Chris,
A 300 and 375 H&H works fine in a good Mauser 98 std. action if openned up "properly" mostly in the rear..Holland and Holland, Westley Richards and others been doing that for 100 years.
