9MM floor loads

Recommended Posts

Posted (edited)

I'm looking for info on soft shooting USPSA floor loads. 

I am switching to Carry Optics for a while (kind of a dare) and will be loading for a G34 and a P320xr. 

I had developed an outstanding load spring combo for limited major in my P16 using tight group; 200gr/830fps/12lb recoil spring that shoots like a dream. I was wondering if such a combo can be had in 9mm as well.

Accuracy counts as well as soft recoil. 

I guess my goal is to make the dot move as little as possible.

Thanks in advance.

Most people find the heavier bullets, and fast powders are the key.

 

Try some 147 gr bullets and N320 or WW231 - very soft and very accurate

in my gun - you'll have to try them in Your Gun.     :) 

 

p.s.   Don't get carried away trying to load to 125.5 PF - that can end up

          "going sub-minor" and you can end up shooting for no score.   Most

          of us shoot for PF 132+.  You won't notice the difference during a match

          between PF 125 and PF 132, but you will make Minor PF every time.   And,

          knock down the steel more reliably.

I shoot Carry Optics and here is my load. I have been shooting 147’s for a couple years now. I have a buddy that likes shooting 124/125 grain Bullets. They’re a little snappier but still soft. He feels like the dot tracks better. His PF runs in the 130 range.

I think I prefer 135 gr bullets for CO, good compromise between the snap of 124's and push of 147's. At least in my guns they feel better. Shoot for a power factor of 130-132 with Sport pistol, Tightgroup, or AA2 if you looking for better accuracy. The Bayou 135 coated round nose I use I've tested likes an OAL of 1.135". Work up a load with the powder you prefer.

3.1 grains of Sports Pistol and a 147 grain FNRP Bayou Bullet seated to 1.135 /1.140 OAL with range brass equals a 129 PF out of my XDM 5.25.  Clean...accurate and soft recoil.

Hello: I can give you a nice Glock 34 load that is accurate and also works in a G17. 147 grain Acme bullet, 3.1 grains Clean Shot, Federal Primers(I have a very light trigger), this gives me a 131-134PF in either the G17 or G34. My 135 load is Acme 135gr, 3.9gr HP-38(231), Federal small pistol primers. This 131-133PF. In the Glock I like the heavier bullets. In my 9mm 1911 I like the 124gr bullets. Thanks, Eric

Been doing a lot of research and I'm definitely leaning towards the 147gr.  I'll be using Tightgroup as that is what I have.  I will also be looking into lighter recoil springs.  I already have 14lbs in both but will have to get a couple of calibration packs (11,12,13) from Wolff and play a bit.    

After a serious practice yesterday I think this is doable.  I cant wait to get them dialed in.

(gosh i love tinkering) 

 

Thanks for the replies, so far.
