I picked up a Winnie 70 in 223 wssm. It shoots like crap and Winchester will not stand behind it and make it right. Rifle is a Coyote Light - best groups are 1.5" to 2.5"+ at 100 yds. I've tried most everything (powder, bullets, scope, good cleaning) and I am now convinced it is the barrel. I have since read some mixed reviews on both the 223 & 243 wssm in the Winnie rifles. Browning has a much better reputation for their rifles in same caliber. I bought the rifle as a light truck gun, not a long range rig. I've looked at rebarreling in either 243 wssm or 25 wssm, with some consideration given to the wildcat 6.5 wssm. Then I looked at the 270 & 7 wsm. They have the same parent case and head dimensions, but case length (and bullet length, I suspect) are longer. These wsm rounds function fine in a short action, but I have heard that Winchester made a special short action for the wssm, that was slightly shorter than their normal short action. Is this true? Can I do a "easy" conversion from a wssm to one of the wsm cartridges by simply rebarreling, or am I stuck with the wssm cartridges? If so, does anyone have any experience with the 6.5 wssm cartridge? Any information would be appreciated - just keep in mind that this gun is to be a light weight, brush bustin' gun for the truck and not a precision rifle. MOA is all I am looking for on a budget.
