hi guys, i currently have a kimber stainless target II in 9mm, i've been wanting to use it for idpa and uspsa, but i cannot seem to find a load that functions well in it. i am using berrys 115gr rn bullets, with cci small pistol primers. i have tried unique and bullseye. the part i don't like is that if i get the load up to where the gun cycles properly i end up with a very hot load. to get the unique to cycle i ended up over 5gr at 1350fps. i tried going down to a 10lb recoil spring which helped a little but then after slide lock and inserting a new magazine it has a feed failure, using wilson combat 10 rd mag's. i guess my dilemma is do i want a faster burning powder or a slower burning powder. i don't really want to go out and spend $150 on different powders till i find something that works then have 6 or 8 different usless pounds of powder. any suggestions are appreciated. thanks guys

I would think you need a faster burning powder. I dont know where unique and bullseye rank on burning rate, but I have had good success with Titegroup in my xd40. I have never had a problem with extraction and feeding. Might want to give it a try, I'll buy it from you if you get it and dont like Big Grin

Your gun should work with either of the powders chosen. The recoil spring has to be fitted to the load, but I think your problem may lie elsewhere. How old are your magazine springs?

they're all brand new magazines, i had to drop down to the 10lb recoil spring to get the gun to cycle correctly and the first couple rounds barley eject because of the upward pressure because they're 10rd mags. just a note it runs fine on store purchased ammo and i was shooting lead bullets a while back and it ran fine on them with unique, but liek i said to get it to run good on unique with 115 gr lead plated im up around 1300fps

Are you sure they are getting a good taper crimp? I have had some not fully remove even a slight bell and they wont go into battery. Doesnt explain ejection problems though, just shooting for answers. Confused

I use 700x mainly because I have a bunch but the burn rate on 700x titegroup and bullseye are darn near the same.

W-231 works great with all weights in the 9MM

I'm thinking bullets. Do these use gas checks?

I have shot a load of 6.0 grains of Alliant's PowerPistol with a 115 grain bullet in a Colt 1911A1 Series 70 that was quite accurate and cycled without a single hitch, although I have never run this load over the chronograph. This load replaced a load of 4.8 grains of Bulleye with the same bullet, which worked well but not as good as the PowerPistol. The PowerPistol load seemed to cycle the pistol more evenly than the Bullseye load.

Sorry, something is wrong w/ your data. I can't even get close to 1300fps using 6gr of Unique & 115grFMJ in any of my 9mm. My working load is 5.5gr of Unique under a 124grFMJ for 1200fps. Try a heavier bullet for a bit more slide inertia. I never change the gun to match the load, but load to match the gun. From Aliant:
115grGDHP 1.125 CCI500 Unique 6.3 1,244
Best recheck your data &/or chronograph.
