I chambered the 9.5x68 on my old .375/06IMP (CZ M98) by simply using a borrowed 6.5x68 reamer and a Clymer .375 neck/throating reamer.

The case I obtained for 'John's' picture, was for that same 1st rifle, which actually received a new barrel in the 90's, also chambered with the same 6.5x68 reamer and my neck/throat reamer. The gunsmith who did this work for the 3rd owner, has since passed away, however he did so and never returning my neck/throat reamer.:(

The original 3 owners, myself and 2 close friends wore the original barrel out (several thousand rounds as a .375/06IMP before the rechamber) - producing over 3" of throat erosion. I don't know how many thousand rounds it went through all-together, but many by me were of non-annealed brass case jacketed bullets (using .223 brass). These might have been extra hard on the throat - or not? I started annealing them for more ductile bullets, perhaps too late, perhaps this made no difference?

The rifle is now with it's 4th owner, a close friend and relative of the second and third owners. I managed to obtain the case in the picture, from him.

I agree, the old 9.3x64 is a marvelous round, duplicating & possibly exceeding the .375H&H. With modern powders and handloads, the old H&H regains any lost ballistic ground, however I did and do prefer the beltless case, as many of you know - going back a LONG way, in fact to 1968 and my 6.5 Rem Mag., which was my initial belted disappointment in belts & FL Sizing. It however, taught me a lot - I was 18 at the time.

Everyone has or can have a .375 Ruger, a wad of money gets it. Not so easy with the wildcats. Anyone can buy one, but to shoot it, one must usually load his own ammo to start with. He or she should or must have a clear understanding of handloading rounds with no direction from the books.

Luckily for the 3rd and 4th owner of the 9.5x68, the second owner gave them a 'prescription' to follow without deviation, which was adhered to.
Seems to me, Bill is running around 2,900fps with 250gr. TSX's, not a max load, but he is happy with it on deer, moose and elk.IIRC
