Pro2AInPA Posted May 10, 2010 Share Posted May 10, 2010 I have a few thousand major .40 rounds loaded with 4.4gr of Titegroup under a 180gr plated bullet. I'm planning on shooting production at this weekend's special classifier match, but I haven't worked up a minor PF .40 load and won't have time to test one before then. So, for you guys who have shot major and minor PF .40, is there a huge difference in feel? Am I setting myself up for failure shooting production with major PF ammo?

Sarge Posted May 10, 2010 Share Posted May 10, 2010 If you are used to the major load I don't see why it would matter for just one odd match. If you are planning on shooting a lot of production with it in the future then you might as well work up a minor load. Link to comment Share on other sites More sharing options...
Chris iliff Posted May 10, 2010 Share Posted May 10, 2010 (edited) NO......answering original question, I just don't think so. I would work up a minor load for the future and wouldn't make shooting major a habit in Production. Edited May 10, 2010 by fourtrax Link to comment Share on other sites More sharing options...
Pro2AInPA Posted May 10, 2010 Author Share Posted May 10, 2010 (edited) I do plan on working up a minor load. I just don't have time to work one up and test it before this weekend. Damn job. Edited May 10, 2010 by Pro2AInPA Link to comment Share on other sites More sharing options...
G-ManBart Posted May 10, 2010 Share Posted May 10, 2010 It's a pretty clear difference when you go from one to the other (like 225FPS difference between 135 and 175PF with a 180), but if you're used to the current load it's not going to be a big deal for a match or two.

Pro2AInPA Posted May 10, 2010 Author Share Posted May 10, 2010 I guess my other option would be to buy a few hundred rounds of minor .40 from Atlanta Arms and Ammo . . .I should be able to sneak to the range to fire a few mags of it to make sure it runs my gun.

Graham Smith Posted May 10, 2010 Share Posted May 10, 2010 I should be able to sneak to the range to fire a few mags of it to make sure it runs my gun. And therein lies the rub... It's not just making PF, it's making PF with a load that shoots well for you in your gun. Link to comment Share on other sites More sharing options...
cheers623 Posted May 10, 2010 Share Posted May 10, 2010 Hope I don't confuse you too much but thought I'd chime in here. My wife and I shoot limited STI pistols, I shoot major, she shoots minor. My load is a 200 gr. Bear Creek that makes a comfortable 173 pf. When I load for my wife all I do is change the bullet to a 155 gr. Bear Creek. Same C.O.A.L., same powder charge, same crimp, etc, etc. This load makes a 140 pf. The difference in recoil is HUGE. I run an ISMI 12.5# spring in my gun and a ISMI 9# spring in hers. When I shoot her minor loads it feels like cheating. They are so soft the front sight just hangs around in a lazy circle when running rapid fire drills or plate racks and poppers. I realize this is not always the case but you might consider just trying your load with a lighter bullet 155-165 gr. and see what you think. Maybe grab 50 or so from a buddy and see for yourself. My two cents, cheers623 DVC Link to comment Share on other sites More sharing options...

My two cents, cheers623 DVC I will definitely consider that when I work up my minor load. I just don't have time this week to work one up and test it before the matches this weekend. I'm shooting production because there's a special classifier this weekend and I already have my limited classification. Link to comment Share on other sites More sharing options...
CocoBolo Posted May 10, 2010 Share Posted May 10, 2010 My .02. I did some testing with Open Minor and Open Major. In a 3 target speed drill with 6 shots reload 6 shots the run times were within .2 minor just a tick faster(total run time just under 6 seconds). Where the difference showed up was in the hits, the major hits were better on every run. Now if we consider that 80% of our time on a stage is not shooting and that is what we need to work on reducing, then minor vs major really isn't a very large factor. In the case of a limited gun, I was running 4.8gr of WST w/185 for a good 172pf Major load, for a steel match and an Action match with no pf I dropped that down to 3.8gr with 185 and yes it was a lot less recoil and flip and it ran the gun fine and hit well enough. I don't think it made my name change from Ron to Rob and don't think I was much faster. Bottom line it is not going to make much if any difference, your brain is wired to only pull the trigger so fast, without a lot of practice its not going to go any faster. Going with un-tested ammo is a nono. To be on the safe side take both with you then you can switch back if its not working for you. Now if you are uncomfortable shooting your current load then it might make more difference. Link to comment Share on other sites More sharing options...
Neomet Posted May 10, 2010 Share Posted May 10, 2010 Ms Neomet has been used to shooting minor in our Tac Sport. This weekend I had her shoot some of my major loads. She shot better and interestingly, preferred the feel of the big boy rounds. Go figure........ Link to comment Share on other sites More sharing options...
Heckler Posted May 10, 2010 Share Posted May 10, 2010 Shoot what you got, have fun. Worry about a minor load, that works in you gun, later when you have more time. Link to comment Share on other sites More sharing options...
fastarget Posted May 11, 2010 Share Posted May 11, 2010 Shoot what you got, have fun. Worry about a minor load, that works in you gun, later when you have more time. +1 Don't change anything for this weekend, you have a load that you are used to and the gun likes it, why risk it and have a bad day. There will be more matches and more classifiers. Go enjoy this one, and plan for the next. Link to comment Share on other sites More sharing options...
kevin c Posted May 11, 2010 Share Posted May 11, 2010 +2 It's just one match. So what if you initial classifiers are slightly lower than they would be with a minor load - that'll change as you shoot the division more with a load tuned to your liking. Getting ammo just for the one match when you don't have time to test its reliability, get the feel of it and zero it, is an expensive and potentially frustrating approach. Shoot what ya got. Work up the load and get it right at your leisure, later. Link to comment Share on other sites More sharing options...
Cy Soto Posted May 11, 2010 Share Posted May 11, 2010 I guess my other option would be to buy a few hundred rounds of minor .40 from Atlanta Arms and Ammo . . . It is true that this is an option but you may also want to consider that changing your PF is also going to change the timing of your pistol.

RobfromME Posted May 12, 2010 Share Posted May 12, 2010 Good morning, I have a 40 Minor load that uses 180 grain bullets (Berry's and Rainier) over 3.6 grains of Titegroup. COL = 1.127" It shoots softer than a 9mm and the brass collects at my feet. The Glock 22 and Glock 23 function reliably with the load, but won't lock the slide back on an empty magazine. Changing to an ISMI 15lb recoil spring in the G22 did the trick, though (I haven't changed the G23 spring yet). I really like the load and in my G22 the PF is 131. No variance in velocity was noted in 38F temps the first time I used my chronograph with them, and 70F temps the second time. Warmest regards, Rob Link to comment Share on other sites More sharing options...
Pro2AInPA Posted May 12, 2010 Author Share Posted May 12, 2010 Thanks for the replies guys. The primary reason I want to get a classification in production is so that I'm classified when I shoot matches in states with mag capacity restritions. I'll primarily stick to limited here in PA.

sperman Posted May 12, 2010 Share Posted May 12, 2010 A very wise friend of mine has told me "don't make getting to the track your biggest race." When I've ignored his advice, I've always regretted it. If you don't have time to make sure your gun will function and be accurate with a minor load, just shoot major.

eric nielsen Posted May 12, 2010 Share Posted May 12, 2010 Post #8 is perfect. I gave the same advice to a friend last nite at a match. You can run lower powder charges with a 180 bullet but that has several potential problems. My advice is just swap to a 155. 2nd place is choose a slower powder for the 180's and stay above 4 grains.

Pezco Posted May 12, 2010 Share Posted May 12, 2010 While there is a noticeable difference in feel between the PF, if you are use to the major PF roll with it. Don't change things before something major or an event you are focusing on. Link to comment Share on other sites More sharing options...
Merlin Orr Posted May 12, 2010 Share Posted May 12, 2010 Just load up 155s with all else the same and shoot. Very noticeable difference in recoil. Contrary to some others I can shoot considerably faster and more accurately with the lighter loads. Only way to know what it does for YOUR shooting is to try it on for size.

hrt4me Posted November 29, 2010 Share Posted November 29, 2010 I have a 40 Minor load that uses 180 grain bullets (Berry's and Rainier) over 3.6 grains of Titegroup. COL = 1.127" It shoots softer than a 9mm and the brass collects at my feet. The Glock 22 and Glock 23 function reliably with the load, but won't lock the slide back on an empty magazine. That is my same load, which functions well in my STI Tactical 5.0 with a 12# recoil spring. Link to comment Share on other sites More sharing options...
