Can I add the 6.5 x 57 to the mix? In a roundabout way, it supports the Swede.
The story is I fancied a Sauer 202 in 0.270, but found no RH ones for sale. However on this excellent forum were two fine people who each had a 202 with both 6.5 x 57 and .270 barrels (as you know, the Sauer barrels are interchangeable with the same bolt). One seller wanted to keep the .270 barrel, the other wanted to keep the gun in 6.5 x 57, so I bought the 0.270 barrel from him and a complete Sauer 202 in 6.5 x 57 from the first chap.
I thought the 6.5 x 57 would be redundant but this Creedmore fashion got me thinking, and Ron Spomer has a great little article on the x55 and x57 on
6.5x57mm Mauser — Ron Spomer Outdoors.
It looks like simply changing the powder, one can make a 6.5 x 55 Swede or 6.5 x 57 Mauser round, do all a Creedmore can do and a lot more: one can make it quieter and 100fps slower, or zip it up 200fps faster than the CM. All these 6.5s take the same bullets, so anything the manufacturers have done to promote the CM fad feeds straight into the 120 year Swedes and Mausers.
Given all of this, with Swedes and Mausers available at much lower prices, why would anyone buy a CM?
