I have been doing lots of research but wanted some more recent feedback from those who have used it or use it. Mostly i am interested in more consistant cold bore shots for target and hunting. No match barrels here yet just my most accurate hunting rifles...tc singles remmys and winchesters...my savage needs no help.
 
IMO for hunting none of that is necessary. If you take your gun out and test your chosen ammo with a clean cold bore and then the next day with a fouled cold bore and make notes on the results you have all the information you need.

My Howa 1500 in 30-06 will put 3 rounds from a warm fouled barrel into a 1/2" group dead center on the site-in. When the barrel is clean and cold the impact moves 1/2" to the left and 3/4" higher. A cold fouled barrel cuts the difference in half. In reality those differences are insignificant when hunting deer with an 8" kill zone.

I'm sorry I can't help you with you original question because I have never used it...
 
Boron nitride can be used as a bullet coating reducing friction and fouling of copper and is supposed to tighten cold bore shots. I will agree with the accuracy of my favorite hunting rifles it is not needed for hunting but i send hundreds of my handloaded down range all year in prep for the season so i will say mostly for target....

Yep.

Target? Does it shoot better? Or does it allow more velocity do to reduced friction? Does it eliminate fouling? If there are no real pluses, no.

Almost everybody in benchrest gave up on moly. Dunno if they have tried boron since then.
 
Or does it allow more velocity do to reduced friction?

I was under the impression that the reduced friction produced less velocity, thus one needed a higher powder charge to mirror the velocity of the same bullet when shot naked.

While I could see the presumed need for long range shooting for prairie dogs or bench rest where minute fractions of an inch make a difference, for most hunting applications, I don't know how much the cost and/or effort of coating a conventional hunting bullet is going to help an average shooter, shooting at a deer sized target at ranges appropriate for the rifle and bullet anyway. Now if you have a favorite rifle that you shoot thousands of high powered loads a year outta and hope to prolong barrel life, I think coating your bullets could possibly help. JMTC.

Yes, my bad, does it allow more velocity due to reduced friction which allows more powder. :)
 
I have been doing lots of research and the reviews are very good...9 out of 10ish see good results and the rest dont see a change but with reduced fouling. Coating the bullets correctly and getting consistant results may be the reason for the not as positive feedback....ill find out soon as mine is in the mail.
