DrLove Posted July 13, 2014 Author Share Posted July 13, 2014 5000000000 Why don't you just tell us what's going on so we don't have to play 20 questions. Nothing is going on really, just curious. I mean to make major, you only need 165. Just wanted to know do people go over 170? How about over 180 or even 190? That's it Link to comment Share on other sites More sharing options...
OperationHitFactor Posted July 13, 2014 Share Posted July 13, 2014 If you load 40 to factory spec or buy factory ammo it can be anywhere from 170-185. Defense ammo can be around 190. If loaded correctly with the right powder it's perfectly safe. Do not try to load N320 or titegroup to that velocity though. Link to comment Share on other sites More sharing options...
OperationHitFactor Posted July 13, 2014 Share Posted July 13, 2014 As for your question. Yes people shoot factory 40 ammo in matches so yes they are shooting higher than required power factor. That is one reason we reload. Softer shooting custom ammo shoots much softer than factory 40 Link to comment Share on other sites More sharing options...
superdude Posted July 13, 2014 Share Posted July 13, 2014 (edited) What caliber? What powder. What bullet? What OAL? See, we're doing the 20 questions thing. Edited July 13, 2014 by superdude Link to comment Share on other sites More sharing options...
Foxbat Posted July 13, 2014 Share Posted July 13, 2014 9mm, PF in the 170-175 range, no signs of over-pressure. Link to comment Share on other sites More sharing options...
Jaxshooter Posted July 13, 2014 Share Posted July 13, 2014 I also keep the PF around 171 to 175 in my 9 mm open guns. Link to comment Share on other sites More sharing options...
DrLove Posted July 13, 2014 Author Share Posted July 13, 2014 well I was thinking 38 super. Just loaded a very flat load at around 183 and wanted to know if this was too high. No pressure signs here either. Link to comment Share on other sites More sharing options...
Nik Habicht Posted July 13, 2014 Share Posted July 13, 2014 I've seen a high power factor north of 200 on Chronoman's signs where he records the highest and lowest PFs seen..... Then again, I've shot matches with a guy who shot a .44 Mag in Revolver..... Link to comment Share on other sites More sharing options...
OperationHitFactor Posted July 13, 2014 Share Posted July 13, 2014 well I was thinking 38 super. Just loaded a very flat load at around 183 and wanted to know if this was too high. No pressure signs here either. Powder, oal, primers, grains, new brass or used, load data? Barrel length, compensator, ports? Pics of the brass and primers from different angles would help. Data dude! We need more data! Ha! Link to comment Share on other sites More sharing options...

Data dude! We need more data! Ha! Well, I didn't think it was that important so I didn't put data. Anyway, it's 38 super like I said, MG115, 11gr of N105, SRP, that's it. No pressure signs that I can see anyway. It really looks fine I was just curious if anyone shoots about 180PF in general. Link to comment Share on other sites More sharing options...
Sarge Posted July 13, 2014 Share Posted July 13, 2014 I don't know if people routinely run 180+ in general but many do run 175+ in Open to get the gas up. Link to comment Share on other sites More sharing options...
OperationHitFactor Posted July 13, 2014 Share Posted July 13, 2014 With N105 you should be fine. That's got to be a pain to load without making a mess. People used to push there guns that high with that powder when the power factor was higher. Link to comment Share on other sites More sharing options...

Yeah that i know but this is so flat you really wouldn't feel that much difference to a .22. My only concern was if this would be bad for the gun on the long run that's why I was thinking of lowering just a little. Maybe go to 10.9 or 10.8 gr instead of 11. That would probably put me at 178-179PF. Link to comment Share on other sites More sharing options...

kneelingatlas Posted July 13, 2014 Share Posted July 13, 2014 If I had some N105 I'd be running a case full behind a 115 . I wouldn't expect a problem going over 180pf with a powder that slow in 38. Link to comment Share on other sites More sharing options...
caspian guy Posted July 13, 2014 Share Posted July 13, 2014 Once upon a time the pf for major was 175. Most of us were loaded close to 180 in .38 super to make sure we didn't have issues at the chrono. No way I'd load that hot now though unless that's what it took to make your gun track right. Even then I'd have to load some batches at different PFs and run some Bill drills to see what the timer said. Link to comment Share on other sites More sharing options...
outerlimits Posted July 13, 2014 Share Posted July 13, 2014 I think it was 180 back in the day. And we were using 160 gr 38 boolets in supers back then. Link to comment Share on other sites More sharing options...
Aircooled6racer Posted July 13, 2014 Share Posted July 13, 2014 Hello: 10.5 grains of N105 will work great with 115 grain bullets. If the gun is built right with a good comp 171-173PF. Thanks, Eric Link to comment Share on other sites More sharing options...
Dranoel Posted July 14, 2014 Share Posted July 14, 2014 I'm betting as lot of .45acp Bowling pin loads would be close to 200 if not over. Link to comment Share on other sites More sharing options...
BSeevers Posted July 14, 2014 Share Posted July 14, 2014 Some of you kids make me laugh. When PF was 175 of course everybody was above that in the 182 range. I have shot guns (not mine) 200+ and yes that is dangerous. Even more so with the crappy powders we had then. Blue Dot was famous for Super Face. Don't get into the "flatter" gun but the timer is the final decision for me. I do miss the older days of real power in DVC and am pretty sure pistol smiths that couldn't make guns run at 175 got the ear of those in charge to lower it to 165. Even Open is a different challenge at 180. Link to comment Share on other sites More sharing options...
xdmjohn Posted July 14, 2014 Share Posted July 14, 2014 I shot my first area match at 187,the guy who was loading for me has since purchased a chrony haha. Didnt notice too much power Link to comment Share on other sites More sharing options...
Toolguy Posted July 14, 2014 Share Posted July 14, 2014 My 44 Mag. pin loads are about 275 PF. That's a 300 gr. bullet at 915 fps. They are kind of a handful, but really get the job done. Link to comment Share on other sites More sharing options...
MarkCO Posted July 14, 2014 Share Posted July 14, 2014 Depends on the gun on caliber. My .40 Super has a PF of 270 in one loading, and yes I shot that load at an IDPA match...once. Link to comment Share on other sites More sharing options...
