I use a Zero 147 gr JHP with 3.2 gr of Titegroup OAL = 1.145. No powder compression. Feeds great in my G17, and delivers a 131 pf.

ptrickamp, are you trying to make any certain power factor? I use a Zero 147 gr. JHP over 3.2 gr of Titegroup. Out of my Glock 17 I get 888 fps for a power factor of 131. This load is mild, and accurate.
I am looking for great shooting practice rounds. Somewhere in the 125 thru 130 PF range. Also I've read that lead should be kept under 1050 fps. I would think of leading the barrel at that speed but I do not know. I've never tried it.
Precision Bullets and Masterblasters bullets use a process similar to Bear Creek. I would not expect a problem with leading at velocities to which you would be loading.
The following are direct quotes from each company's website.
"You can fire our bullets at over 2000 feet per second with no leading and no copper fouling and no messy lubricants." - Precision Bullets' website
"You can use your favorite loads and data, it does not matter whether it is a load for jacketed or lead bullets. Our polymer coating can handle velocities up 1400 fps, before breakdown." - Masterblasters' website

My mousefart 147s, put in the right spot on a falling piece of steel will get the job done as efficiently as a hot 115 load delivered to the same spot......
Accurate delivery is more important than bullet weight or power factor, if the steel's been properly calibrated, and is in good working order and design....
+1. Get the hits and everything should fall into place...assuming that steel was properly calibrated.
+1 again. Good hits are essential. However, knocking over steel is a matter of MOMENTUM transfer not energy. Two loads that generate the same power factor (a momentum based formula) should take down steel with equal aplomb. What it comes down to is what kind of feel you prefer in your loads. Slower or faster/snappier? I guess this comes back around to what gets you good hits faster?

Assuming good storage conditions, what is the shelf life of pistol primers? I have some old ones that I would like to use for practice, just want to make sure they are safe.
Thank you
Assuming good storage conditions, NON-CORROSIVE primers will last ~30 years. CORROSIVE primers last longer.

Thank you Hank, I was wondering the same thing. For those who load Clays above Hodgdon's book data, is there another reference source that you guys are using? If so, what is it?

I've used CCI and Federal sp primers through my Dillon 550 with no problems. I would go with whatever is cheapest and commonly available, unless you're running it out of a revolver with a reduced power hammer spring or a Glock with a reduced power striker spring. Then I would go for the Federal.

Great thread, just what I was looking for!
It took me a while to find it, but I'm glad I took the time. Lots of good info.
Thanks everyone.

Tony,
I agree, it is difficult for me to believe such a large varience between my loads and yours/wlktheduk's. I'll pull a bullet and double check. As for the plated bullet being that much faster, I'm not sure. I'd say its a definite "mabe".
I know that lead bullets are faster for any given powder charge b/c of less resistance going down the bore, and plated bullets are between lead and jacketed in that respect. I'll do some follow-up tests and post what I find.
I get roughly the same results as wlktheduk.230 Precision Delta FMJ
4.5 Titegroup
WW Cases
CCI or WLP primer
OAL 1.260
Yields about 725 fps from my 45 Edge.
I know there are variances between guns but I can't imagine 175 power factor with 4.3 of Titegroup.
Is it possible the plated bullet could account for this?
I would check my scales carefully.
You may be dropping more powder than you think you are.

Wow your results are very different than mine. Your load is .3 gr more than mine but is almost 30 fps slower. Perhaps my chrono is fast.
230 gr Berry's plated RN
4.3 gr Titegroup
CCI 300 LP primer
PMC cases
1.260" OAL
761.0 FPS = 175 PF from Glock 21 w/ stock barrel. I will chrono the load through my Para P14, but historically, the P14 is ~15 fps faster than my G21.
This year I've changed over to Clays. In my guns, it has been cleaner then Titegroup, and accuracy is good. (when the loose nut behind the trigger does his job
) 4 grains of Clays
230 grain Rainier plated RN
Federal LP 150 primers
OAL: 1.260
average velocity 734 FPS/ Power Factor 168.820 from S&W Model 625 revolver, 5" barrel
average velocity 727 FPS/ Power Factor 167.721 from S&W Model 625 revolver, 4" barrel
I had been using Titegroup for the last two years, with the following loads:
4.6 grains Titegroup
230 grain Zero FMJ/RN
Federal LP 150 primers
OAL: 1.260
average velocity 736 FPS/ Power Factor 169.280 from S&W Model 625 revolver, 5" barrel
average velocity 725 FPS/ Power Factor 166.750 from Colt's Series 80 automatic, 5" barrel
I know that lead bullets are faster for any given powder charge b/c of less resistance going down the bore, and plated bullets are between lead and jacketed in that respect.
