I am looking for someone that can re-bore and re-rifle a Gary Schneider 6mm 1 in 10 twist barrel. I am wanting to re-bore to at least a 7mm but not sure of the twist yet ,originally the barrel was chambered in 6mm mach 4 and has had about 200 rounds down the tube.I talked to Mr. Schneider and he said NO!!!!!!!!!!gun)
