Hi all, after much waiting my Rihnland arms 45acp mauser conversion kit showed up on the brown truck today. The magazine adapter looks real nice, the lock ring for setting the headspace looks like a high quality piece. The barrel
The outside is very rough. I guess that I can file it down, then sand and polish it. The rifleing looks good from the breach end, but at the muzzle there is lots of rings like a bad cutter reamed it out or something. The crown is rolled over inside the bore real bad. If you put your pinkie finger in there you might not get it back out with all the skin attached. I can recrown on the lathe with no problems. but the rough bore at the muzzle has me wondering?? Will this cause leading problems? I only intend to shoot cast through this. Or do I need to hand lap it? The chamber looks clean and straight with a chamfer leading into it.

On another thought, I tried to pull the worn out 7mm barrel off of the action and couldn't get it to budge. The barrel just slipped in the wooden blocks in the vise, so I put a thin wood shim in the vise and put the action in it then used a pipe wrench on the barrel. I tweaked the action abit but the barrel didn't move. I put the barrel in the lathe and took a relief cut right up next to the action down to .9" and still no luck. What should I do next to remove the barrel? Heat the front action ring with a torch slightly?

Too bad you don't have some Gibbs penetrating oil, it's actually alot better then Kroil. But anyways I would soak it with whatever you have availiable, should have done that first I reckon.

I made a regular pair of steel barrel blocks that bolt to the anvil part of the bench vise and got the old 7mm barrel off. Rihnland replied and wants me to shoot the barrel to see if it leads with the questionable rifleing at the muzzle. I'll recrown, inlet the stock and should have it to the range this weekend. I'll wait on polishing the barrel and blueing it until I see if it shoots or not. Now I just need to build a spanner wrench to set the barrel lock ring.

Then I can try some of 45nuts 380gn boolits in Harumph loads. I may have to size down some 500's and shoot them also.

After a couple of us went together and bought a bore scope I was saddened by the interior of several of my TC barrels. Looking through the scope they look like very fine internal threads. Apparently ALL expense is spared on "smoothing" the inside of the barrel before rifling.

Gives me a new appreciation on REAL reamed finish!

As I have said before my 1886 Winchester has one of the smoothest barrels and it was made in 92.
As in 1892.

TC, darn thats like TC isn't it? Thats the reason I won't buy any more TC's. Darn barrels fouled so bad with copper or lead it drove me crazy. I can shoot my Rugers for weeks with no fouling.
