Re: .260 barrel on a 30-06 Rem 700 SPS???
Well look at it this way. The M24 Sniper Rifle is a long action 700 and about 15,000 of them have been built and work fine. They are all 308. Since the 260 is just a necked down 308 case with same body dimensions there is no reason why it won't work. Last rifle I built was a long action 700 in 308.
Got a buddy who wants to build a 260 on a Rem 78 (LA) and when he gets the barrel we will put it on.
Don't understand the term won't line up with a 260 barrel. They are all screwed in the same hole?????
Actually is a much better deal that a short action as the mag is easier to load and you can load bullets further and further out to chase the rifling.
You can also get a stock the Army is now using that converts a long action into a magazine fed rifle with floating forearm. Has a 10 round mag to boot.
The ultimate conversion is converting a M1 Garand to 260. I know the guy that built it and he said it fed just fine.
