I have an early Type B sporter in 9.3x62 which needs to be rebarreled. I'd like to keep the look original and, based on what I have read, it seems Walter Lothar makes the best barrels. However, I called the company and they could not immediately tell me whether they could match the barrel. They suggested I look at the contours here: http://www.lothar-walther.com/268.php

The rifle is a standard Type B with round barrel, rear tangent sight, ramp front. If anyone has any thoughts on the right contour, I'd be grateful.

I'd prefer not to rebarrel the rifle, but since it keyholes shots at 25 yards, I don't have a choice.

many thanks

I am curious, do you have an idea of the keyhole cause? What bullet are you shooting, what is the barrel twist, is the rifling damaged from corrosion? What Velocity are you shooting the bullets? Is the crown damaged?


I had an original FN action 270 Weatherby several years ago. It shot the 130 grain bullets fine, but 150 grain bullets would keyhole. I measured the twist at 14 inches. Put a 10 inch twist barrel on the action and the 150 grain bullets shot great.

A friend's 270 Winchester also had keyhole problems. He lived in Alaska and carried the rifle muzzle up on a sling. 20 years of the Coastal Alaska rain and salt atmosphere had rusted the rifling out for about 3 inches at the muzzle.
