analog_peninsulaAnyone rebarrel M60 Schultz and Larsen?
Hi everyone,
I've got an M60 in 7x61 with a barrel that was allowed to rust by the previous owner. Is there anything unusual about rebarreling an S&L action?
Thanks
No. They are pretty straightforward. I remember these Danish rifles from 1960. The 7x61 was the 7mm Rem Mag until that came along. Rear locking lugs; the barrels are threaded into the receiver in the standard manner. But I have never done one; Speer probably has.

speerchucker30x378I have rebarreled quite a few over the years and punched out a good many 7x61s to 7mm Remington when the supply of Norma factory fodder dried up in the 1980s. Like dpcd says there is nothing special about them.
The only glitch that comes to mind is the exaggerated feed radius on the chamber. A lot of guys think that radius is just a product of Friday and poor machining. It's actually essential.
The bolt raceway in back lug actions is very narrow in guns like the Colt Sauer, Remington 788 and the Danish Schultz & Larsen. For some reason these types of rifles can suffer from dead feeds if the radius on the chamber is not fairly pronounced and smooth. The sharp edge will actually dig right into the shoulder and as long as you keep good force on the bolt, the feed will be locked solid. As soon as you let off the pressure just a bit, the cartridge loses hold and feeds right in fine. It all seems to stem from the fact that the cartridges are going into the chamber to straight on and and fast and don't tend to slop, rattle and flop around on the way in. As odd as it seems, I have seen this kooky problem a few times and I even had a Colt Sauer come back to me after a rebarrel I did, along with a very pissed off customer. Pay attention to the way the original barrel is set up on that one and run a bunch of chargeless dummys through it afterward just to be sure.
