I attempted to develop some data for these with various calibers and powders over the years using a chronograph. I experienced inconsistant results. There doesn't appear to be any published data in the public domain. The manufacture won't release any "due to legal liability". I would think with the liability environment being what it is, they wouldn't put a product out there without any guidance, but hey thats an opinion. If anyone has some experience with BJHPs, please share your knowledge, and if it is with ball propellants, even better. Thanks.
Are we talking Rem.GS? I find they need a little more powder to get the same vel. as conventional JHP. I believe this is because of the short driving band. Others, like MG, I have no idea.
IF YOU AREN'T HANDLOADING, YOU AREN'T SHOOTING ENOUGH! If you could make your own gas, wouldn't you???

Yes, specifically the GSs. I found that to get any consistancy I was over the published data, but with no signs of excessive pressure. I also assumed it was due to the lower resistance of the bullet in the bore keeping the chamber pressures lower. I suspect powders that work better for the lighter projectiles are the answer. Thanks.

No, not really. Typ. thought is to use faster powders for lighter bullets. Reality, you'll still get higher vel. w/ much lower pressure using a med. burn rate powder. Just up your charge wt. Reloading manual recipes are only good for the exact bullet/powder/case/primer combo. There is no published data for the GS, so how do you know you are over max? You have to develope your own loads when you change components. My exp. w/ the GS in several calibers is you need slightly higher charge wts., at least w/ med. burners, than conventional JHP.

I've loaded Remington GS bullets using the same data I use for regular JHP's, generally data from the Sierra manual. Its been my experience they don't chrono any slower than other bullet types from Remington or other makers, in fact they may be a few FPS faster. I've crhono'd GS bullets in the .45 acp, .357 mag and .38 spl. I've loaded and shot a few from the 9mm but have yet to run any over the chrono. I've found them to be a nice accurate bullet.
.38 spl GS loaded on top of 6.0grs of Unique, GFL case (Fiocci), WSP primer, average velocity 1,053 fps, shot at 25 yds NRA 25 yd Timed and Rapid target.
I like the GS bullets for the accuracy you mention and terminal performance, which is why I am messing with them in the first place. I had a significant quantity of WAP (out of production for a few years now) left over from when I was shooting heavier bullets. I could never get what I considered consistant velocities with this powder and .40 135gr Noslers. I have also noticed it doesn't seem to burn as cleanly as other ball propellent applications. I like the ball propellants (metering and flame temp) but the performance of Blue Dot and Unique in .40 are impressive. I use the Sierra Manual whenever possible. Back to the bench and range. Thanks.
Here is how I've been loading the Rem Golden Sabers. 380 ACP, 103gr GS, 4.1 grs Unique 9mm, 125gr GS, 4.9 grs Universal 45 ACP, 230gr GS, 5.4 grs Universal These loads work in my guns. Yours may be different. Your starting loads should be 10% less powder. Stick to min OAL std or greater.
