Marakby Posted April 22 Share Posted April 22 What powder do u IPSC standard major shooters use for a 180gr bullets (40S&W), I used to use Titegroup but I’m not comfortable with a max load to reach barely the required PF. What other powder alternatives? Link to comment Share on other sites More sharing options...
CurlyShuffle Posted April 22 Share Posted April 22 What gun are you using and what power factor are you trying to achieve? Link to comment Share on other sites More sharing options...
Marakby Posted April 22 Author Share Posted April 22 The min. Is 170, so aiming for 175 not to worry about Chrono. Link to comment Share on other sites More sharing options...
Joe4d Posted April 22 Share Posted April 22 most guys running really fast powders in 40 major are running longer than spec ammo, which tend to work better in 1911 type platforms. Truckloads of tight group have sent truckloads of 180's down range at 170 pf,, Has probably been the most common loading for many years in the US.. Cant speak for 175 though.. If you arnt comfortable with tight group,, a simple look at a burn rate chart and what is available in your area should suffice.. PIck a powder with a slower burn rate which should get your velocity with lower pressure. Reloading manuals should be full of 180's at 980 fps loads.. Thats pretty much standard 40 stuff.

Dr Mitch Posted April 22 Share Posted April 22 Titegroup is perfect for 40 major. No pressure issues at all, been a winning combination for decades. Link to comment Share on other sites More sharing options...
Marakby Posted April 22 Author Share Posted April 22 The threshold for major is 170, so I wanted to be just 5 above, to evade an old chrono or cold weather (Canada) that may kick me to minor at a L03 match. I’m now 172 with a truckload of Titegroup. So I rather ask my fellow expert fellas as part of my research. Link to comment Share on other sites More sharing options...
ltdmstr Posted April 22 Share Posted April 22 We used N320 for .40 SW back when the UPSA major power factor minimum was 175. Never had any problems. I believe the load was 5.4g at 1.200". Link to comment Share on other sites More sharing options...
shred Posted April 22 Share Posted April 22 Yeah, N320 was one of the gold standards. Some people (BE included) played around with Clays but it was very twitchy and unless loaded long could easily blow cases. Link to comment Share on other sites More sharing options...

MadBomber Posted April 23 Share Posted April 23 WIN 244 is also a great powder. I think mine is 5.3 grains at 1.195", makes about 173 PF. Link to comment Share on other sites More sharing options...
