	Possibly set the barrel back far enough to eliminate the rear dovetail?

	Joe poor choice of words perhaps, however, it has no rear sight dovetail. moodyholler

	Both are original barrels. 32” letters as a 25-20 ss. Has now been rebooted to 45 colt. Second gun has not been lettered yet. moodyholler

	moodyholler - Glad to hear the barrel was not set back. As redsetter said, rare to see a barrel ordered without rear sight dovetail.

	James- Both are great examples of yesterdays rifles- high quality at modest cost, so rare today- I would have thought a #1 barrel in 45Colt would leave very thin barrel walls, but you've proved me wrong-- Thanks for sharing these beauties!!!

So with a case diameter of .478" it leaves a pretty thin wall indeed, but not bad at the chamber. The thin area is the muzzle where the .452" bore and .70" barrel leaves .243" left, and that's less than 1/8" per side on the barrel thickness. .1215" thick.

	Never really thought about it before. Is there a standard minimum? Less than 1/8" sounds spooky

	I'd have to measure, but it sounds pretty close to the amount of metal that remained at the muzzle on the 1886 Extra Light Weight barrels.

	The chamber is the weakest and highest pressure area, especially at the extractor cut. The LW shank size is .825. There is a old "rule of thumb" that I always use, it's 1/2 the shank diameter for the largest case head. Using that, I wouldn't go larger than .410 - .415. In the case of a case head of .415, that would leave a wall thickness of ~.184, at the root of the thread. The 45 Colt, would only have about .130 wall thickness. You would have to be VERY careful, drilling the scope block holes. I just did some calculations on the pre-64 model 70 Win, using the 300 H&H case. From the root of the thread, to the belted case head is ~.190, for a much higher pressure cartridge. Frank
