Hi
i have a spare barrel in 375H&H for my brno 602 and wonder if it will fit another action like winchester m70 magnum action or anny other model ?
best regards
yes

Only fits BRNO 602. These are metric threads. Shank diameter in imperial numbers 1.1" 13TPI(from memory).

Yoy simply cut off the threaded stub, re-cut and re-thread it and you ar "good to go". Bill Leeper did one for my buddy for a nice P-64 H&H action I sold him and it works perfectly....given Bill's smithing skills, that ain't a surprise.

The Brno ZKK series, while crude in comparison to their fabulous 21 anmd 47 series rifles, will usually shoot "lights out" and the 602-.375s are particularly good. Mine shot 300 SilverTips into .6" with boring regularity, so, this barrel is worth the cost of adapting to the Winnie action.
