I talked to the guys I got the gun from last night. He says it is a large ring. 1.100" X 12 thread Model 98 Argentine Mauser. He put a Shilen 1:9 twist 28" #5 contour Chromolly barrel on it. He had no luck with 140's but 130's did awesome. He just got tired of making brass for it he said.
He gave me a 6.5-06 AI neck sizing die and says he used a270 seating die. Think I'm gonna order a set of FL's and seating dies to match the caliber.
Any hints or secrets about trimming the brass before or after I neck size it?
XXXXXXXXXXXXXXI make my brass from 30-06 brass, there isn't any trimming but I do turn them because of how much the brass thickens up...
That's what I was talking bout. I just picked up the die and the Lee case turning tool. Gonna be a learning curve with this little finicky thing I'm sure. tks
