This horse has died from the constant beatings. Are we lawyers are just gun owners. The Winchester rifling is a Micro Groove style? It seems this has appealed more to the "PC" than to the re-loaders..
I don't know if a B92 has " Micro Groove " or not, I have one so I'll check it and see. From experience with loading a couple of 336s in 35 Rem I have to shoot "fat" bullets. I cast a 200 RNFP from clip on wheel weights and size to .360. Anything smaller skids on the shallow grooves and leads the bore pretty bad and accuracy is off. Groove diameter one is .3585 and the other is .358
It was used to describe the Marlin rifling they came up with. If Winchester copied it, you/they can call it rifling like the Marlin Micro Groove, but you can't call it Micro Groove, that's what a patent its all about.No Winchester never used the Micro Groove word. It is used to describe the type of rifling Winchester used which was the same.
Bingo!The Winchester rifling is a Micro Groove style?
Ask - Why did Marlin start making barrels , with deep-cut Ballard-type rifling (6 grooves)?
so I asked earlier what max size diameter lead bullet should I use in my marlin 336w 30-30? and any mold recommendations?
