Makes me wonder how that bullet would do on varmints like, foxes, bobcats and coyotes.
New Sierra bullet?

Originally posted by KentuckyBuddha View PostI agree and I originally thought of something down in that weight class.

You know with the idea of getting 7N6 kind of cavitation and silly speed out of something that won't likely overpenetrate.

So if someone spins up a solid copper bullet with the same exact same dimensions as a 123 SMK would the lighter weight of the bullet (but same bearing surface) result in significantly more speed or do you have to reduce the bearing surfaces as well as weight to get a significant speed increase?

There is a 28gr Aluminum core copper jacketed bullet loaded by FN for the 5.7X28 that works quite well from the PS90 on coyotes, haven't recovered one yet though. They do make a nice bright silver colored splatter on steel targets. The only yotes I have shot with these were 75 to 100 yards away and there was an exit on broadside lung shots, the yotes did not go very far though, dead within 10 yards.
"SS195LF (lead free)The SS195LF is a commercially available cartridge that features a lead-free primer and produces ballistics similar to the SS192 round, which it replaced in late 2004. It uses the same 1.8-g (28 grain) copper-jacketed aluminum core bullet as the SS192, and it can be identified by the unmarked, hollow void at the tip and the silver-colored primer. The SS195 is classified by the ATF as not armor-piercing, and it is currently manufactured by FN Herstal in Belgium"
Size of these bullets is very close to the Hornady 40gr V-Max

I am a 5.7 guy too ( I have several Five seveNs and several PS90's, or I did before that terrible boating accident :cough cough. I didn't mean to make it sound like an ENTIRELY original idea. I also didn't realize the 195 was for sale again. Last I had heard they were only going to offer the 197 in USA#1.
Hard to know what the concept would do in a longer, wider, heavier application however.
Perhaps it is best to see how our new toys turn out before we move on to new playthings. : )
