9mm: 115gr LRN 3.6gr Bullseye

[BluBob]

I helped a buddy set up his reloading process tonight and used this recipe as a test batch. All seat well using his barrel as a gauge. I wanted to stay on the light side, and am wondering if anyone has any experience with this or a similar load. The load is within specs for similar loads in my Lyman's and Speer, but I could only find a 120gr LRN or a 115gr jacketed. No 115gr LRN was listed. The gun is a Ber92F. Thanks.

Don't know if this helps as I was testing a 125 gr LRN, but here is my data.

No help here either with the 115, but I too use 125 grain LRN (Missouri Bullet Co) with 3.5 grains of Bullseye in my stock 92fs. Excellent accuracy with no feed or extraction problems. I doubt you'll have a problem using 3.6 with the 115.

again, like the others, no 115 LRN data.
however for
124LRN I use 4.0gr BE and have tried 4.3 and 4.6 (HOT!)
for 147gr lead I use 3.5gr BE and it shoots well. so, your much lighter 115gr bullets will be on the light side and should be plenty safe.

 

[BluBob]

Thanks for all the replies. I too am thinking he may have to bump up to around 4.0gr BE to get a reliable feed. Option 2 would be a shift to a 125gr LRN, probably from MBC.

Back in the late '90's I was shooting a lot of bullseye through my S&W PPC-9 semi-auto's. I used 4.5gr with Remington, Winchester, and Hornady 115gr JHP's. With the Sierra 115gr JHP I used 4.3gr. These gave the nominal 1,175fps for the 9mm from a 4" bbl. A bit faster with 5" or 6" bbls.

For some guns the 3.5 will be below functioning level. I find that 3.9 is Ideal for 122-124gr Cast bullets. Gives just about 1,100fps and typically good accuracy.

I found that WSF, Win231, or Hodgdon's LongShot to be far superior for the 9mm.

I load mine with 4.2 for 1076 f/s. This is with 115gr Berrys, but lead should be close, as I used lead data.

It is obvious that if you go to a lighter recoil spring, 3.0 grains of BE will work. Our stand load for a 124 gr cast bullet (lee) is 4.0 grains and it functions in everyting. be safe
