Berger 185 juggernaut at 2630 fps.  G1 bc  .560 - G7 bc .283

Gun is a R700 .308 - 20" -  1/12 twist

Don't know if it matters but where i shoot I'm usually around 500 too 1000 asl

I think in my area (1000ft ASL), the 77gr SMK goes 5200yds, and the 175gr SMK goes 5400yds. I'd guess the 185gr would reach 5500-5600yds.



ETA: I got 5900yds with the 185gr.

I tried the ballistic calculator and got the same result

I should have been a little clearer

I was wondering what it's effective range would be I.e. at what distance would it still be supersonic

It starts going transonic (~1300fps) just past 1000yds, and is subsonic just before 1300yds.

IME the 185Jugger does fine in transonic.


Mine did fine to 1005yds on a cold day at below sea level pressures starting out at 2545fps.




The question is, what do consider effective? If you want to make 80% hits on an IPCS silhouette then probably 800yds. Just a matter of what you want to achieve.

I'm not sure what to consider effective, I'm new to this

I just hit on a really really accurate  load with the 185 juggers loaded to mag length so I was curious what it would be capable of.

I'm still working on 208 amax loads. I can load to 3.030" and still be .020" off the lands. I'm trying RL17 right now.

Yep. The 178 BTHP does also.

I've even shot the 178 AMAX from a short .308 gas gun and got respectable accuracy at 1000 yards (transonic around 950y)

By the way, there is a setting in JBM to have it indicate when the bullet is expected to enter transonic flight.
