    Though I wouldnt really call it slightly longer. It's pretty significant. Here is a still shot of 55, 62, 69, and 77 grain bullets. Its from the video which I havent watched, just got the pics of the different bullets from it. A federal 55 grain FMJ has a listed length of .745 inches and a 77 grain SMK has a listed length of .994 inches.
    As a side note, M855 is a bit longer than some other 62 grain projectiles. .044 longer than Hornady FMJ, and about the same length as a Sierra 69gr SMK (855 is .006 longer). Steel being less dense than lead. Its always made me wonder why no one makes 69gr FMJ, like how 69gr 5.45 ammo used to exist, being made from 7n6 jackets with the steel portion of the core replaced by lead. Id buy the shit out of 69gr FMJ projectiles if they were available and priced less than Hornady or RMR OTMs.

    jello shows earlier upset than the SMK. Id guess the plastic tip plays a role in that, but Im not certain. People that shoot TMKs report jealousy-inducing exterior ballistics.

    No weights on these recovered bullets.

    So I'll assume that the tipped version makes it much less yaw dependent? i.e. you'll have the same performance as the HP one but at longer ranges? If so that makes it kind of an ultimate combo for that bullet weight (if fragging is your intent).

    Basically (correct me if I'm wrong) the TMK extends the predicted terminal ballistic range of the older SMK projectile (?). If you wanted that type of terminal performance at longer ranges the TMK should be your choice from what I gather.

    Its not yaw dependent at all, like all the newer bullets designed with terminal ballistics in mind they all use hydraulic pressure to initiate fragmentation, expansion or whatever you want the bullet to do. Thats why idiotic statements like "There's been very marginal improvements in powder and bullet manufacturing" are laughable. Yawing is terrible mechanism and introduces fleet yaw and AOA issues, better to make a bullet that expands or fragments via hydraulic pressure from the tip like the TMK because its more efficient and consistent. Thats why everything from M855A1 to TMK are fragmenting in the sub 1900 fps range. Its not just a SMK with polymer tip, its a completely different bullet design with increased BC AND increased terminal ballistics in mind.

    Wow pictures are really worth 1,000 words. I used to think TMK where just a tip in a SMK.

    Might be looking for TMK in the future and see if I can load them deep for a rainy day.

    Yeah until he posted those pics I thought the same thing!

    The picture is great, but having a clue to where one can find these illusive 69 & 77 grain .224 diameter Tipped Matchkings as a component bullet would be great.

    The 77 gr SMK was made for being very accurate at long range punching a hole in paper. And it is.

    But testing in gel has shown it penetrates deep and expands perfect.
