Synthetic bullet coating question...

I ran across this ammo from an SG Ammo email. It says that the bullet is lined with a synthetic jacket that prevents the bullet from actually contacting the barrel. Wouldn't this nullify ballistics tests? If so, I'd think they'd be trying to ban it?

    I admit I don't know that one. I have tried a number of variously coated rounds over the years in .243 and 7mm Rem Mag. I did not chrono them, but uniformly found the were less accurate in my rifles.

    Your link is not live, but I looked and it does have 1 reviewer who is enthusiastic and touts it's accuracy.

    From Federals website it appears to be similar to the old Nyclad bullets or the powder coated rounds the cast bullets shooters are using . Just a polymer coating on the bullets . With cast lead bullets it works well to limit fouling and leading. You no longer have to lube the cast bullets .

    Used on fmj projectiles it is more a marketing ploy than anything else.

    TSJ is the real deal. I use this specific ammo in my suppressed AR9 'pistol'. Doesn't leave any residue in bore or muffler. Flat nose, soft(er) lead projo transfers surprising amount of energy to test media.

    It's a thin layer of material so the metal part of the bullet is still getting deformed and leaving marks. I know a number of folks that run this or similar in their competition guns.

    This might be one of those times when it's best to stay quiet so as not to give them something more to think about!

    This coating is essentially a cheaper component than a copper jacket. It does not conceal rifling marks nor is it intended to.

    Syntec was designed to be affordable range ammo & then 6-8 years or so back, they realized the competitive shooting market and began making it to align to USPSA power factor requirements.

    It has become great match ammo and If I’m shooting a major match it is my go-to ammo because I know exactly how it will perform.

    Thank you Warbirds for educating me on this . I honestly had no idea it was being used for competition.

    I've been moly-plating bullets for my varmint rifles for many years. My modest expectation.…..was to extend the period between bore cleanings.

    It worked......🤠
