Has anyone tried Tac and 155gr Lee in 7.62x39 CZ 527

[cmeeks]

I would like to push them in the 2000fps neighborhood, and my boolits are quenched wheel weight with GC and lubed with Red Angle. I have a lot of Tac and would like to use it if possible any info or advice would be greatly appreciated.

I may be wrong but, I think that TAC may require higher pressure to burn correctly. Only one way to know for sure though. 4895 works like a champ for your requirements and WC-844 is a very close runner-up.

Here's some j-bullet loads I chrono'ed in my CZ 527

26.0 gr. RL-7 150 gr. Sierra .311 R-P 7 1/2 R-P case 2186 fps

26.7 gr. RL-7 150 gr.Sierra .311 R-P 7 1/2 R-P case 2208 fps

TAC is too slow IMHO. 2200, 2230 or Exterminator would be a better choice

Try 24gr H322. I use it as the standard load in my CZ-527. I shot heavier charges, but the best groups came in at 23-25gr. Load development was done in mid 30*sF, and accuracy was unaffected (with the 24gr load) with temperatures were near 90*F. I was using the C309-150F (160gr) so your boolit should work with similar charges.

2200 will give you noticeable flash from the short barrel.

I get good results in a Mini-30 using 28.1 gr TAC and a 150gr jacketed bullet. It's a slightly compressed load. I'm just starting to get into casting and haven't tried TAC with Boolits yet.

This worked pretty well for me in a MINI-30 with a 0.310 groove dia.:
LEE 312-155-25 water quenched from the mould of WW and some tin.
They were sized 0.313 with gas checks.
Wolf magnum primers
Full case (lightly compressed) of TAC
Hit to the same POI as 147gr FMJBT with the same charge of TAC and regular primers.

Didn't notice any leading. Will load up and shoot a batch more.
