Win WST and 147 gr. a good combo for a newbie production loader?

[hovbuild]

I load for a cz, 124 MG JHP, short 1.08 and found that 4.3 wst is the ticket for now.. They run at 1080+ and group real well, I do headstamp and run the same headstamp per shoot. I also have to ever so slightly adjust the crimp from win to fc to get closer results between the two.

I've run WST w/124gr MTG and found that it was a bit snappy for my style. In 100+ temp it took 4.7gr at 1.145 to get up to speed. The ES and SD where significantly higher than TG at 4.3gr which was bit flatter. 3.9gr of N320 made a lot better load even better than 3.5gr gr of Clays. The N320 felt like a mouse fart steel load but the Cronoed at 130pf. The TG/WST loads were 135pf. WST is my choice w/40 185gr moly bullets.

I wouldn't recommend this load for a beginner, signs of

high pressure in early development of this load.
