For those of you looking for a accurate, affordable, and reliable alternative to Black Hills 77 grain OTM, I strongly suggest that you consider the IWI Razorcore 77 grain SMK OTM LR MOD-1. I picked up some from SGAmmo.com for roughly $0.67 / round which is about 40% less than what you will pay for new civilian Black Hills 77 grain OTM (red box). Moreover, the IWI round has some advantages to the civilian BH load in that the primers and necks are crimped and sealed as per the pictures below:
These features can be found in true milspec MK 262 MOD 1 but not the civilian equivalent, and is big plus for ammo that you plan to use for duty applications.
I tested some of this ammo through my Noveske SPR build and NF 2.5-10X42 pictured in post # 683 here: https://pistol-forum.com/showthread....Gallery/page69
This rifle is zero’ed for BH 77 grain SMK and typically holds about 0.8-1.25 MOA 10-shot groups with a quality factory version of the 77 grain SMK including the Black Hills. The specs for the rifle and glass can be found in post # 46 here: https://pistol-forum.com/showthread....-gas-gun/page5
Testing conditions were as follows:
Shooting from Caldwell front and rear sandbags
Temperature 77.9
Pressure 30 Hg
Humidity 83% (yuck)
Altitude 1256.6 ft
Wind 1.6 mph, 279 degrees
A 10-shot group was obtained at 100 yards yielding the following results:
The first two shots were a combination of a clean cold bore and my shitty marksmanship from sandbags, but the ragged hole produced by rounds 3-10 is more representative of the ammo’s capability. Overall, extreme spread of 1.43” / 1.37 MOA is respectable for a 10-shot, factory load. It is also reasonably close to what @Molon has produced with the BH 77 grain SMK load.
Average velocity 10 feet from the muzzle for 5 rounds measured with a Competition Electronics Chrono was 2760 +/- 13 fps (extreme spread 35 fps).
Overall, this is excellent milspec 77 grain SMK ammo. I’m stocking up on it.
