    ZF4 scope calibration for which 8mm ammo

    Does anyone know what particular loading of 8 mm ammo the ZF4 scope for the G 43/K 43 rifles was calibrated for? Was it 198 grain bullet at a particular velocity or was it something different? I’d like to try and duplicate the loading so the scope calibration matches my bullet weight and velocity for all the various ranges on the BDC adjuster knob

    A Collector's View - The SMLE Short Magazine Lee Enfield 1903-1989. It is 300 8.5x11 inch pages with 1,000+ photo’s, most in color, and each book is serial-numbered.  Covering the SMLE from 1903 to the end of production in India in 1989 it looks at how each model differs and manufacturer differences from a collecting point of view along with the major accessories that could be attached to the rifle. For the record this is not a moneymaker, I hope just to break even, eventually, at $80/book plus shipping.  In the USA shipping is $5.00 for media mail.

    The 198 ammo was out of service by then , replaced by the 178 SMK type ammo . The SMK was made to be close to the 198 sight settings so the older 198 sights could still be used .

    I would say the standard 7.92x57 Mauser S.m.E military ball ammo introduced in 1940 to save on materials after the war had started. The S.m.E round had a mild steel core, lead jacket round which was 178grn. After 1943, this round was further re-designed and designated S.m.E.lg by further reducing the amount of lead, resulting in a longer projectile of 39.8mm to maintain the 178grn weight.

    I doubt the scoped G43's users got issued with the special sniper ammo that the scoped K98kicon snipers got issued with.
    Just the thing for putting round holes in square heads.

    Thank you. Any idea the velocities of these 178 grain projectiles!
    I have some PRVI 175 FMJs I could use. I also have a 175 gr bullet mold I plan on trying at some point. Will do initial testing with those in the K98K. Those won’t be terribly fast.

    Out of a K98kicon, muzzle v and e about 2600 fps and 2600 ft.lbs.
