If you had to choose between Mk262 and Mk318......

[ABNAK]

Wow, this thread is almost 6 1/2 years old! Damn, time flies as you get older.....

I guess since it's been resurrected from the dead I'll state that I currently have an equal amount of both Mk318 and IMI Razor (Mk262 clone). Of the two I have zeroed all my AR's to Mk318. So I guess I would say that Mk318 is the 1st choice, and I have a Mk262 clone to back it up.

MK262 usually has a 3-4” neck before it upsets and has been known to ice pick. Of the two, MK318 would be my choice.

Indeed, back in the mid 2000's when OTMs were the best performers available, between the 77gr SMK, 77gr Nosler and 75gr Hornady the SMK performed the worst. I guess all those gun magazine articles worked because people think Mk262 is a good performer to this day. Considering what is available today Mk262 is a mediocre performer at best and only should be used when long range accuracy is the main mission goal.

77gr TMK however perform splendidly on soft targets according to https://www.rokslide.com/forums/thre...-moose.130488/

Well yeah it’s a totally different round.

Well yeah it’s a totally different round.

I get to pretend to be prescient in this case - if I'm going with factory loadings, then these preferences matter - if I'm finding something different, that's exactly the sort of round I'd want to be dinking with. That being said, finding much of anything loaded is the real goal, and I'd still focus heavily on how little the actual terminal variation is across a lot of the arrival velocity ranges, a hit is generally a hit, and most any useful round is at least a decent roll of the dice.

I think the above is often forgotten as I get caught up in the minutia of this round vs that round. Trying to be able to hit armed, moving targets on a two-way range is the goal and every round is the same if you miss. That being said, exceedingly hard for most of us to train to any degree of mastery in that regard. I'm a fan of whatever most closely matches my go to round, the 50g TSX by Black HIlls. So MK318 for me as I'm in and around buildings, cars and other barriers way more than I'm out in open desert.

I'd prefer SOST by default, but if I HAVE to make do with Mk 262... well, it's better than M855.

In a market like this, I'll take whatever on the Doc Roberts List I can get at an almost-tolerable price.

In my experience M262 performed pretty well. My old team leader who has spent the last 15 or so years as a 18B has several deployments using it and says the same thing.

Now, from just how the two rounds are designed I would bet the Mk318 does do better with terminal performance. But since I dont find the M262 performance to be lacking, I'll stick with it and the external ballistics advantage. Because, like said above, a hit is a hit.
