G17fan Posted July 5, 2014 Share Posted July 5, 2014 Happy Independence day everyone! I am trying to find the load data on line for a 45ACP load.... Here is what I am using 200gr LRN N320 LPP OAL - 1.245 to 1.252 The Lapua data is for a 6 inch barrel. My gun is a Springfield Armory 1911 loaded model with a 5 inch barrel. thanks!

ttolliver Posted July 5, 2014 Share Posted July 5, 2014 Here's some data for some 200 LSWC loads run through my Springfield RO. Not ideal since these loads didn't get fast enough for our game. I was testing some 230s at the same time and decided to just keep going with the 230 LRNs. But what you're looking for is likely just north of 5.1gr N320 COAL 1.240 Federal LPP 4.9 gr 157 PF 5.0 gr 161 PF 5.1 gr 165 PF Link to comment Share on other sites More sharing options...
HOGRIDER Posted July 5, 2014 Share Posted July 5, 2014 Lyman doesn't have data for a 200g LRN, but for their 200g LSWC #452630 @ 1.235 they list for N320: Start: 5.1 Velocity: 746 CUP: 10,000 Max: 5.5 Velocity: 865 CUP: 17,000 If your barrel likes it, I would start with an OAL of 1.250 and go from there on the LRN. They don't have a listing with N320 and their 225g LRN. FWIW: I've read on several forums that Bill Wilson's "pet" 45acp load is a 200g SWC in front of N310 or Bullseye.....

RePete Posted July 6, 2014 Share Posted July 6, 2014 Look here for VV powders. It only lists a LSWC bullet but will put you in the right ballpark. Just watch your OAL. http://www.vihtavuori.com/upload/guide-and-brochure/vihtavuorireloadingguideed13_2014engwww.pdf Link to comment Share on other sites More sharing options...
G17fan Posted July 6, 2014 Author Share Posted July 6, 2014 Thanks Repete. I shoot a 5 inch barrel. This data is for a 6 inch. Link to comment Share on other sites More sharing options...
wheelie Posted July 7, 2014 Share Posted July 7, 2014 Thanks Repete. I shoot a 5 inch barrel. This data is for a 6 inch. It does not matter. You can shoot the same load in a 5 or 6 inch barrel. And each gun is different. To find out how fast your particular gun is with a given load, you'll have to chronograph the loads in your gun.

G17fan Posted July 7, 2014 Author Share Posted July 7, 2014 I totally understand. What I should have stated was I loaded 5.2gr and my PF was 150..... The difference between the 5 and 6 inch in FPS is noticeable in the PF. I've since loaded up some 5.4gr and will chrono sat after our match.

RePete Posted July 7, 2014 Share Posted July 7, 2014 Thanks Repete. I shoot a 5 inch barrel. This data is for a 6 inch. Knock about 25 - 30fps from the listed velocity. Link to comment Share on other sites More sharing options...
G17fan Posted July 7, 2014 Author Share Posted July 7, 2014 When I Chrono'd 5.1gr it rendered 753FPS which is 97 less of where I needed to be. Stock barrel for my SA.... Link to comment Share on other sites More sharing options...
HOGRIDER Posted July 7, 2014 Share Posted July 7, 2014 (edited) G17fan: IMO, if your loading 5.1gr of N320 @ 1.245-1.252 with "any" properly sized (.452) 200gr lead bullet, you should be pushing 900fps out of the 5" barrel! Realize your after a 170PF, but I'm wondering how accurate your chrono data is? Also, do you feel confident that your actually throwing 5.1gr? Have you checked the sizing of your 200gr LRN? Not doubting your abilities; but something just doesn't add up....... Edited July 7, 2014 by HOGRIDER Link to comment Share on other sites More sharing options...
G17fan Posted July 8, 2014 Author Share Posted July 8, 2014 Thanks. The 200gr weighs 197gr... Verified the drop is accurate. Also at a loss.... Link to comment Share on other sites More sharing options...
HOGRIDER Posted July 8, 2014 Share Posted July 8, 2014 Ok. What about bullet diameter? ~.452"? Link to comment Share on other sites More sharing options...
G17fan Posted July 8, 2014 Author Share Posted July 8, 2014 Yes .451.5 so .452 Bear Creek lead RNHB Link to comment Share on other sites More sharing options...
HOGRIDER Posted July 8, 2014 Share Posted July 8, 2014 IMO, based on verifying your powder drop, bullet weight, and bullet diameter, I would be looking for another chrono to test with. Can't think of anything else left in the equation..... Good luck! Link to comment Share on other sites More sharing options...

peterthefish Posted July 8, 2014 Share Posted July 8, 2014 With a HB bullet profile you may need to load a little shorter to get the expected velocity - the HB essentially increases case volume meaning lower pressure / velocity. Link to comment Share on other sites More sharing options...
HOGRIDER Posted July 9, 2014 Share Posted July 9, 2014 peter: Believe you hit the nail on the head! I had not noticed it was an hb bullet! Good eyes! G17, find you some different/solid base 200gr lead and try again! Start with 4.5 - 4.6gr @ 1.250 and go from there. Link to comment Share on other sites More sharing options...
