135gr coated 9mm loads. Login/Join

I bought some Bayou 135gr RN HiTek coated bullets and did some testing. I’d like to stick with the 4.2gr load but I’ll have to check again in the cooler weather. I’m not familiar enough to know how temp sensitive this powder is.

I started with a 1.32 COL and 4.2gr Hodgdon CFE-P, the same as I was using with 145gr bullets. Researching between Hodgdon and Speer showed that as the lower end, sort of splitting between 124 and 147 data.

Some limited data:
Chrono at 15’, at 10’ I was getting crazy readings. 75* out of a CZ Shadow 2.

I like the 135's fine, just prefer the abundance of 145-147's out there. In my 5" M&P Core and 9L, my 145 S.E. coated and LRN load is 3.4 gr CFE-P. At a charge of 3.3 gr. the avg was 862, thus the extra 10th to make PF comfortably. I also use a tungsten guide rod and 13 lb. spring in the Carry Optic Core gun. 4.3 gr of HS-6 averaged about 920 and good accuracy. My previous go to load has been 4.5-6 of Hs-6 with the 145 LRN, averaging in the 965+ range. That is a stupid accurate load in the pistols above. Just throwin out some more data to put in your data base Smile I am always tinkering...3.2 gr of AA #2 is in the 128-131 PF range...

I am trying not to tinker too much. Haha. Good info for future though, thanks!

It’s interesting how powder charges vs velocity varies from many listed loads. 3.8 doesn’t quite get it for me, but 4.2 is solid. I’ll try these again in my Glock 17 as well.

TRshootem gave some good info. Find the load you like that make PF (if you're competing). THEN match your recoil spring to that load. Order different weights (lb) and experiment.

TR, maybe you mentioned it in another thread, but can I ask your COAL?

I'm finding that to have a really consistant plunk and spin I need an ever shorter round. 1.11 or so, and it works great. The 1.125 or so rounds are about 50/50 on easy spin but plunk and gauge fine.

I'm thinking of backing down to 3.8 for the 135s at 1.115. This fits in all my 9mm guns and hopefully with function.

So far on the loads I've tried, I've not had to change the recoil spring from the stock. The CZ ejects nicely pretty straight to the right and about 5'.
