rustybayonet Posted October 14, 2017 Share Posted October 14, 2017 Just wondering? Everyone seems worried about prefomance of spp in .45acp. I'm a poor shooter, so I have been loading spp45 for a while now. I only use them for my plinking and never had a problem with ignition or accuracy. Again just curious to find out what problems you have had? Link to comment Share on other sites More sharing options...
Mushki25 Posted October 14, 2017 Share Posted October 14, 2017 I kinda prefer ssp brass. They let met make a run of 45 without changing over my primer assembly on my press. I know I add an extra 0.1 of powder because they were slightly slower. I can't say for sure but I believe it was 30 feet per second slower. I have also used magnum primers with them. It was still slightly slower but not by much. Link to comment Share on other sites More sharing options...
tires2burn Posted October 14, 2017 Share Posted October 14, 2017 I use spp brass when I don't want to collect my brass. I use lpp mainly because it's plentiful at the range I use and they let me pick it up. As far as performance goes they feel the same to me. I load the same load in both and can't tell the difference.

Steve RA Posted October 14, 2017 Share Posted October 14, 2017 I use it so that I only have to buy one primer for 9mm, .45 ACP and .223/5.56. Presently I use Tula small rifle magnum primers for all. Will have to choose another primer when I run out of the Tulas. Link to comment Share on other sites More sharing options...
mont1120 Posted October 17, 2017 Share Posted October 17, 2017 Just a loss of velocity, about the same as Mushki25 commented on. Watch it if you use them for major matches on the chrono. Other then that I shoot them just fine. Link to comment Share on other sites More sharing options...
jcc7x7 Posted October 19, 2017 Share Posted October 19, 2017 Never a problem and as stated do your due diligence at your chrono and use them. With some powders I find not enough difference to have to change load. other powders have to go up a couple tenths Link to comment Share on other sites More sharing options...
Yeti Posted October 19, 2017 Share Posted October 19, 2017 Only the loss of ~30-50fps depending upon the load. Oh..and the hand sorting. Link to comment Share on other sites More sharing options...
Steve RA Posted October 19, 2017 Share Posted October 19, 2017 Using Australian Clays for powder, my velocity did not change when going from LPP .45 to SPP .45. I use SRMP with the SPP brass. The primers aren't available at this time (Tula) and neither is the powder but I'd imagine that any fast powder like that version of Clays would have about the same results.

Austings Posted December 4, 2017 Share Posted December 4, 2017 I use SPP brass for my plinking stuff. I don’t have much of it so i just reload it more often than LPP. Link to comment Share on other sites More sharing options...
10X Posted December 5, 2017 Share Posted December 5, 2017 I don't load both, so I can't comment on problems. My only experience with SPP .45 brass is when I accidentally pick up a piece or three on the range, toss it into my mixed brass plinking bucket, then eventually try to cram a LPP into it. This leads to breaking my loading rhythm, and lots of bad language while the offending piece of brass is stomped flat on my basement floor.

hgr2 Posted December 17, 2017 Share Posted December 17, 2017 I have never intentionally loaded 45 ACP brass with Small Pistol Primers but I have found a very positive method of identifying them little %^#@$DS when I find them mixed up in my real 45 ACP Brass.

GlockCanMan Posted December 20, 2017 Share Posted December 20, 2017 It won't be too much longer and they will stop making 45acp lpp brass. Link to comment Share on other sites More sharing options...
DsWright Posted January 14, 2018 Share Posted January 14, 2018 I see lots of comments all over the net about a 30-50 fps loss with SPP brass over large. My chrono disagrees with this. I also worked up my load and found the sweet spot with OAL and powder charge that gives a very consistent 750 FPS. I don't see a measurable difference with small over large, shooting cast and powdercoated 230 Gr Truncated cone. The only difference i see is that when using mixed brass, the spp have a lower SD. That i think comes from the fact that only a few headstamps have SPP and are newer. When loading LPP who knows how old the case is, and many many more headstamps.

gtaylor07 Posted February 25, 2018 Share Posted February 25, 2018 I load .45 for a friend's 625 and oddly enough we noticed a significant increase in light strikes using small vs large primers. This was the case using both factory Federal, as well as me hand loading with Federal primers seating them deeply. I'd of never thought that would be a problem, but it's consistently going from 1 or 2% light strikes with LPP, to I'd guess around 15% with small.

Sent from my Moto G (4) using Tapatalk anytime you have light strikes with Fed primers, that you know are seated correctly, you have to think its the firearm. Can't get any softer than fed primers. 2lb trigger means nothing if it doesn't run reliably. Link to comment Share on other sites More sharing options...
gtaylor07 Posted March 4, 2018 Share Posted March 4, 2018 Correct he needs to get the Apex pin for Federals, but what was noteworthy was the difference between large and small varieties. Not anything I had heard of, but very real.Sent from my Moto G (4) using Tapatalk Link to comment Share on other sites More sharing options...

Sent from my Moto G (4) using Tapatalk Makes sense, the small might be a bit harder, the smaller diameter would mean the folded edges might give it a bit more rigidity maybe? but when you are riding that fine line of reliability, the risk vs reward is way off balance to the risk side.

diesel855 Posted March 12, 2018 Share Posted March 12, 2018 I only load 45 acp and 9mm so not having to swap press back and forth is a plus, only have to stock spp is nice. When you get a LPP mixed in and attempt to prime it just won't seat ( pockets to large) not a big deal. I mainly use federal case which seem to run very consistent length. Using coated bullets various powders and chromo to confirm results. Small pistol primers have been a good experience for me, many people avoid them making them easy to attain. If your just starting to reload this may be a good way to go. Link to comment Share on other sites More sharing options...

That's classic! I find them by having my 650 stop when it shouldn't. I just grab it off the press and substitute a sized and deprimed LPP brass. I've been taking them to the range and leaving them on the bench for some other brass scavenger. Link to comment Share on other sites More sharing options...
