WildOkDee Posted December 18, 2019 Share Posted December 18, 2019 Anyone have some average velocities and power factors? Other than what their website states, please. Pro's or Con's? Quote Link to comment Share on other sites More sharing options...
marshal stone Posted December 18, 2019 Share Posted December 18, 2019 I use 4.2 gr. VV N320 with 230 gr. Desperado Bullets, Federal magnum primers and have never had a problem with making power factor. Don't remember velocities but make 165-172 PF in my gun.

Garrison Joe Posted December 18, 2019 Share Posted December 18, 2019 A con - if you are sensitive to expensive powder, it's at the top of the price list. Fewer vendors carry it. A pro - usually accurate. Good luck, GJ Quote Link to comment Share on other sites More sharing options...

Marshal Stone Marshal Stone, are you using a hard crimp on that or just mild? I use precision bullets with a polylube hybrid coating. He suggests a starting crimp that measures .468 to .469 at the top of the brass...which was belled to accept the .4515 dia bullet. Thanks for any additional info!

marshal stone Posted December 20, 2019 Share Posted December 20, 2019 Dee I just verified mine are crimped to .470. My bullets are .452. With the .4515 that .468 or .469 might be the way to go. I use a Lee factory crimp die as the last stage. Hope that helps Marshal Stone Quote Link to comment Share on other sites More sharing options...
WildOkDee Posted December 20, 2019 Author Share Posted December 20, 2019 I did my crimp with this batch, at .47" too. I hope to put some rounds on chronograph on Saturday or Sunday. That is one plan, subject to modification, change, deletion,....etc Many thanks Marshal Stone! Quote Link to comment Share on other sites More sharing options...
Garrison Joe Posted December 20, 2019 Share Posted December 20, 2019 I think you will have good luck with the taper crimp at 0.470" The .45 auto does not need as much crimp depth as most revolver loads anyway, so Precision's recommendation is probably a little tight for auto. We are not running high-recoil loads (to cause bullet pull), and if your gun feeds well without jamming nose of bullet into ramp or barrel hood (no bullet collapse), you should be good. You can always do the "loaded round push test" to see if crimp is snug. Take a round you loaded, hold in hand, push nose into a hard wooden object (like a garage door frame). If bullet does not push into case further, and bullet does not rotate within case either when twisted by hand, crimp is good.

WildOkDee Posted December 20, 2019 Author Share Posted December 20, 2019 Hey GJ, interestingly enough on the Precision bullet website, David, the owner, says the same thing for a bullet crimp test! Thanks! OkDee Quote Link to comment Share on other sites More sharing options...
C.N. Double Posted September 5, 2020 Share Posted September 5, 2020 Dee -- did you end up sticking with 4.2gn of N320? I'm fixing to load some now using the same powder, but with coated bullets, which will likely produce less velocity. Quote Link to comment Share on other sites More sharing options...
C.N. Double Posted November 3, 2020 Share Posted November 3, 2020 For anyone curious -- I ended up settling on 4.6gn of N320 and loading my 230gn Hi-tek bullet to 1.22" OAL. In my worn Remington R1, I got pretty consistent 168+ PF. Quote Link to comment Share on other sites More sharing options...
Samuel B Carpenter Posted November 3, 2020 Share Posted November 3, 2020 howdy WildOkdee found my old reloading data and this is what it says, these days I use a bit more powder to get a 160 PF you need to chronograph your gun to get your PF 45 acp 4,25 / N320 – 220 RN Modern Springfield 1911 – 715 ft/s - 157 PF - teste date 20.june.2019 hope this helps regards Samuel B Quote Link to comment Share on other sites More sharing options...
