praetorian97 Posted March 6, 2015 Share Posted March 6, 2015 (edited) Anyone loading the 147 flat nose bullet for their SP01s? A few of us locally are getting jams on unload show clear command. During course of fire its fine because the bullet has left the case when the case is attempting to be ejected. On USC you are trying to rip the bullet out of the chamber. OAL 1.135 If you are what OAL are you getting away with? Edited March 6, 2015 by praetorian97 Link to comment Share on other sites More sharing options...
selecw Posted March 6, 2015 Share Posted March 6, 2015 Not exactly what you are asking .. but I use Blue Bullets 147r LRN at 1.092 OAL and 3.3gr of 231. I went with the RN to get the best possible feeding and so far it has worked well (except with Aguila brass, but that's another story). Link to comment Share on other sites More sharing options...
Andreas Posted March 6, 2015 Share Posted March 6, 2015 That's asking for trouble unless you've throated your blaster. Process variation is going to give you +/- 0.005" or so, and there's the risk that long rounds will cause binding in the magazine. I've throated all my CZs and learned to keep my seating die set to 1.125". Link to comment Share on other sites More sharing options...
praetorian97 Posted March 6, 2015 Author Share Posted March 6, 2015 Selecw - Its seems that the shoulders on the 147 FN are wider than the RN. So it will get stuck in the chamber. Curious what length I would need to push these back to. Link to comment Share on other sites More sharing options...

praetorian97 Posted March 6, 2015 Author Share Posted March 6, 2015 Round nose is whats working at the longer load lengths. Flat Nose seems to bind up at the 1.135 length. Link to comment Share on other sites More sharing options...

open17 Posted March 6, 2015 Share Posted March 6, 2015 Running 147 Bayou over 3.4 N320, OAL 1.140 in a pair of CZ 75 SP01 Tacticals. No problems at all. Same load in the CZ's, 4 G17's, 2 1911 9mm's and a M&P Pro. Runs 128-132 PF depending on the gun. Link to comment Share on other sites More sharing options...

OAL 1.135 If you are what OAL are you getting away with? At 1.13" with the Bear Creek version of this bullet, I had no issues with the stock CZ barrels. I have throated most of mine and I have gotten away with 1.160". I would have gone further but I was already close to the max of my magazines. In both scenarious, they functioned flawlessly with 500 rounds of each length. OP I would try seating them deeper to 1.13" or 1.125" and try again.

Smitty79 Posted March 7, 2015 Share Posted March 7, 2015 That picture looks like a Blue Bullet 147 FP. That's my favorite bullet. I've had about 9000 of them through a CZ85, My Shadow and My son's Shadow. All were at 1.12 and I've had zero failures. Link to comment Share on other sites More sharing options...
tbarker13 Posted March 7, 2015 Share Posted March 7, 2015 I used the flat points out to 1.15, but I did have the barrels on my CZs throated. Link to comment Share on other sites More sharing options...

praetorian97 Posted March 7, 2015 Author Share Posted March 7, 2015 Thanks Everyone. I had concerns going below 1.13 but it looks like everyone is running sub 1.13 with no issues. Link to comment Share on other sites More sharing options...
SDM Posted March 7, 2015 Share Posted March 7, 2015 (edited) What's the advantage of the FP over the RN? There seems to be consensus that the RN doesn't have the problem. Edited March 7, 2015 by SDM Link to comment Share on other sites More sharing options...

myproverb Posted March 7, 2015 Share Posted March 7, 2015 Start with 1.05" to 1.1"--this resolved my issue. Good luck! Link to comment Share on other sites More sharing options...
fastlane604 Posted March 8, 2015 Share Posted March 8, 2015 I can load round nose out to 1.17 but I have to keep flat nose bullets down to 1.06. I have not throated my barrel. Link to comment Share on other sites More sharing options...
praetorian97 Posted March 8, 2015 Author Share Posted March 8, 2015 What's the advantage of the FP over the RN? There seems to be consensus that the RN doesn't have the problem. Cost and availability. I can get the Flat Point for a very reasonable price @ www.leatherheadbullets.com I'd prefer the 147 in a round nose but more money doesn't justify it.

Gcarr Posted March 8, 2015 Share Posted March 8, 2015 I load 147 (home made on Magma Master Caster) @ 1.130 to 1.135 (3.2 of N320 ) ... Many many thousands shot in my 75 shadow ... No issues. Link to comment Share on other sites More sharing options...
