[Variable]

I found a great deal on some 69gr SMK Match ammo from PPU through Midway. I ordered a bunch and it showed up pronto. It has 28 5 star reviews.

This will be decent for the DM portion of the course if you are shooting 5.56/.223 Rem AR15. You'll have solid performance out to at least 400yds, and out to 600yds if the wind isn't too bad. I usually prefer the 75gr BTHP, A-MAX, and 77gr BTHP for 600yds with my 223 Wylde AR's.

If you're shooting Grendel, any of the factory loads will be better on steel compared to .223 Rem, especially your 123gr stuff. It hits almost like a .308 Winchester.

Partial OT, but kinda related-- There is another new 77gr. Mk262 Mod 1 clone out from IMI that is cheaper than Black Hills and actually available if you want to try some new distance fodder.

Wideners has it: https://www.wideners.com/itemdetail.cfm?...18|830|845

I chrnonoed it, and it compared very well to Black Hills velocity wise. I haven't shot it for accuracy (no range time to do it yet), but the other guys on Arf have. It's good to go.

ETA: Here is the chrono data I originally posted here: http://www.ar15.com/forums/t_3_16/633767...4#i6354960

/////"Okay, I got off my butt and went out for some real world chrono data. I didn't have time to go to an actual range to shoot for accuracy, just a chrono run at the corner of the driveway (sorry neighbors.LOL) I only used one barrel length, and no suppressor. It's 16deg. F outside, and I was short on time and daylight.

As a comparison I also fired Black Hills MK262 Mod 1 (White box "Seconds") ammunition aquired from Cabela's in the past.

Hopefully this info is helpful. Yes, I know these aren't 20 shot strings, and they weren't measured across an Oehler, but unless someone wants to send me free ammo and a free Oehler, these will have to do for now. I had to ditch two string attempts for piles of "error" failures, and this ammo gets expensive when you are just wasting it.

So.... In my Colt LE6940 (16" chrome 1:7 twist) I got an average of 2742fps from the IMI ammo, and an average of 2635 from the Black Hills. The temperature was only 16 degrees, but I had just brought the ammo from inside. I doubt it was much of a factor.

All said: YMMV, my .02, etc., etc....!




ETA: If my 6940 averaged 2742fps at 15 feet from the muzzle, what does that equal for "muzzle" velocity? How do you figure that?
ETA #2: I'm pretty surprised at the numbers I got, but I got what I got. I can only post what the chrony says. Maybe the BH lot I was using was a tad slower than normal? I'm sure stuff varies a bit, I dunno?"/////

Not looking to derail Paul's thread, just tossing in some related info.
