I tried a search to see if this has been discussed-to no avail. Does anyone have the load data for the M62 tracer rounds? Bullet weight is 145 gr. I'm trying to find the powder data, and any other pertinent information.
I'd imagine the charge is similar to the M80 data (147 gr bullet) as these all should have the same trajectory???
As always-very appreciative of anything you can share.

C.R. is right with 46.0 grains of WC846, just checked my old TM. The two main powders of choice by the Gov't for 7.62 are or were, are IMR4475 and WC846.
