Hornady 165 Grain SST in 308, what are you pushing this bullet to?

[rockchalk06]

Going to work a load up soon with this bullet. This will be used in my 18" 1-10 M5 barrel. Hornady factory loading with this bullet is 2850 out of a 24" barrel, so it's smoking!

Vihta Vuorti only has a max velocity published at 2680 with a 24" barrel.
Hornady maxes at 2600 and 2700 FPS
Looks like Tac can get me close to 2700 as well looking at Western and Hodgdon data.

Anyone loaded this bullet and had good results?

Thanks in advance OSA

Says superperformance blended propellant 100 -200 fps faster than commercially available powders.
I think that means you can't load that fast.

I don’t know how these two bullets compare dimensionally but Alliant Powder has 2000-MR that will push a Speer 165 grain BTSP safely to 2840 fps. Naturally you would want to compare the Hornady SST to the Speer BTSP dimensionally but I would bet one could safely and taking it slowly load the Hornady with this powder to 2,840 fps (24” barrel).

I keep intending to try some 165 gr SST’s in a 308 load, because I love them in my 270 load but never have.

Just so you know, Midway sell blems that look and perform exactly like SST’s. I’m pretty sure they are SST’s but are sold as generic blems.

Barrel length is not the only factor in velocity read this small test.
Yes the longer barrel was still faster but not by the 100FPS I have read about. for a 4" difference.

Ruger american 22" .308 & Savage 10 18" velocity differences

I went to Lexington today and shot a few over the chrony. Now I have read that IMR 4064 gets back the lost velocity in a short barrel .308 for some Handloaders. I built 5 rounds in a ladder With a 150gr flat base Speer spitzer bullet. Starting at 45.5 gr and then up the charge .5gr at a time...

Sorry, not the 165gr SST, but I'm 99% sure it will be an excellent performer down to 2K FPS (and probably even a bit lower) impact velocity. I've had very acceptable accuracy results with the 150 SST out of an 18" barrel too.

I've done the TAC thing for my 18" Wilson Combat barrel in my M5 build, and maybe my 18" Criterion barreled M5 (that rifle and load data are with my father). Just make sure that when you're pushing velocity (and pressure) with a double-based or ball powder that you're doing it in conditions you'll be hunting in...or do it in warm weather as a precaution.

Not trying to insult your intelligence if you already know this...but powders like TAC are well over 1FPS velocity change per degree in ambient temperature change. Pressure corresponds accordingly.

Some factory loadings like Superformance use a proprietary propellant mix that allow for velocities that us handloaders can't obtain without going ridiculously overpressure.

Best of luck.

I remember reading this thread. I've got plenty of 4064 on hand to try as well. It's what made the best load for my 20" bolt gun with 168 grain ELDM's.

Superformance is available to the reloader. I'm using it to reload 30-30 but have yet to put it across the chrony to check speed. New to me caliber so I'll have to use factory data for speeds to compare to.

I appreciate it.

I've used 225 SST in my .338RCM and 140gr in a 7mm-08. Accuracy is great, performance on deer was not great imo. I won't hunt with them anymore.
