lead poisoner

My browning a bolt 7mm wsm has the boss with muzzle break.It came with an extention so I could remove it.In which I did.And replace with the extension.I all so would not recommend the boss system.If your worried about recoil buy a good recoil pad.I don't think in my opinion that a little tighter pattern is goanna make a difference on game further than one would actually see them.I don't think I will ever see anything out past 400 yrds and if I do, I am shure I could stock to within 350yrds fairly quickly and easy. Save your money. I can't speak for competition shooters but as a hunter,it's not worth it. I did read that silencers added accuracy all so and fps.But they are around 1k just for the silencers not include the gunsmithing.
