Interesting to notice they have always recommended not loading beyond 1200fps but they have .357 mag data showing loads in excess of 1500fps.
Any velocities over 1200 FPS we recommend either our Heavy Plate Concave Base or Hollow Point products for superior accuracy.
They have two categories of plated bullets. Anything over 1200 fps they recommend .......
I’m merely pointing out a discrepancy that should have been included in the manual as well as on the website. A first time user of their products may miss this information and wonder why things aren’t going the way they should when going by the manual.Uh, well, if the velocity of the round is over 1200 fps ................
very interesting. I use the Bore tech Eliminator bore cleaner which works on copper. I also have their dedicated copper remover. The Eliminator has done a great job as long as you let it sit for about 1hr with heavy copper fouling. Have not had a chance or needed to use the dedicated copper remover yet.I have run the standard plated over 1200fps through my Henry .357 and accuracy wise out to fifty yds seemed fine, but it took me a week to clean the copper buildup out of my barrel. I have run Berry’s heavy plated and Xtreme heavy plated over 1400fps in the same rifle with only minor copper buildup similar to what a jacketed bullet would do.
Good to know, thanks UN.You'll find the Bore Tech dramatically faster than either ammoniated or ammonium oleate-based cleaners. It uses a chelating compound like EDTA to do the job.
The fastest copper remover I've encountered is KG-12, which seems to combine chelating and a small amount of ammonia. But it has two drawbacks. One is that it doesn't turn blue or green, so you can't tell by its color when the cleaning is done. You want to have a borescope to check or you want to follow up with another cleaner that changes color to prove the copper is gone. Second, a couple of folks have said it is hard on some finishes, so you want to test it on a hidden spot somewhere. But man, it eats copper fast. Wet a bore with it and plug the ends and come back half an hour later. Only the worst fouling will need any more time.
