    Thanks, but here in warm & typically San Antonio, TX I'm a bit gunshy of the more temperature sensitive powders like H414. We haven't hit a 100°F day yet in 2019, which is unusual. Last year was very hot & dry, we were already in Stage 2 water conservation restrictions at this point last year. This year the aquifer level has stayed above average so no mandatory water use restrictions at this time.

    There's a guy on another forum who's posted using 66 grains of Ramshot Big Game under the 286 grain Nosler Partition for his 9.3X62mm loads, others post they have also worked up to this load with success. His real name is John Barsness. I plan to send that thread to Reed's as a point of consideration when I send my 9.3 mm Mega bullets. I have purchased two boxes Reed's 9.3X62mm ammo with the 9.3mm at 2350 fps MV, but haven't gone to the range yet with my recently new to me 9.3X62mm Zatava M70 rifle.

    I’ve got two load work ups ready to go:

    250gr Accubonds
    Varget
    Lapua Brass
    210M primers

    270gr Speer Hot Cora
    RE-15
    Lapua Brass
    210M Primers

    I hope to get out tomorrow and shoot it. Testing will be done as is, but I just picked up a VX5 2-10 from the classifieds. The low-end, FOV, and locking turret are well worth a few ounce weight penalty over the 3.5-10...just waiting on some 30mm Talleys to get here.

    Looks like it has had some work done to it, unless CZ started changing their bolt handles.

    How so? I’ve owned a few 550s and they all looked identical to this one. I know the magnums have a hollowed bolt knob, but every medium I’ve seen has a swept handle with solid knob.

    If it rains much more here in the S.A. area the aquifer might come up to the surface and create a new river walk....man we've had a lot of water over the last 6-8 months.....

    Beautiful caliber. If l ever find a ZKK 600 in 9.3 × 62 , I'll snag it. Wally Johnson actually used this gun on Cape Buffalo in Mozambique in the 1950s when Ammunition for his .375 HH Magnum was in short supply .
    His was rebarrelled from a .318 Westley Richards .
