6mm /.243 hunting success on Big Game

[Chris in TN]

Am I right that the matching X is more or less just a harder-core thicker jacket MK, sort of analogous to the TGK, just without the tip?

Probably great at higher speeds but maybe not so great at longer ranges?

AKA Sierra’s answer to a question nobody asked?

That is incorrect.

To expound- they may be a thing “no one asked for”, but they aren’t “tougher” than regular SMK’s. The real issue is that they have weirdly low BC’s on some of them- the 107gr 6mm specifically.

Interesting. Thank you!

That is incorrect.

From what I understand around the MKX, they have a softer lead core in comparison to the SMK. In the FAQ section on Sierra's website they mention under "... why not to use MatchKing for hunting" that they use softer lead core in their hunting line. My thought process with that methodology would be similar to that of what Berger uses with the thinner jacket on their hunting line, that it will take less change in momentum and energy (because physics still applies in impact and yes there will be energy loss due to heat with the deformation and disruption taking place) for disruption and fragmentation to take place.

I have shot the 200 MKX out of my 30-06, I had them at 2830 fps, pretty uncontrollable for a 7 lb rifle, I don't recommend shooting that combo without a muzzle brake or braked suppressor, it takes a lot of focus to maintain a controlled shot. With that, they fly great out to 1,000 for what little experience I have with them.

I also have loaded the 135 in my 6.8 Western. I didn't do a whole lot. I may want to try a powder around the 4350 burn rate.

I did have a friend harvest a buck with the 175 MKX with his .308 this year. About a 100 yard shot, went 30 yards and tipped over.

They are stupidly accurate and seem consistent in flight so far.

For killing I’d say in what I’ve seen so far they have been fine. In the 6mm flavors I’ve killed with, I might be giving up a bit of advantage to the 95 TMK and 103 ELDX.

It’s only 9 kills though so hard to really make any strong claims for or against them.

I’m using a 7.5 twist steel barrel.

Have you been happy with the neck length. I am shooting the 108 elite hunters and so far my sample of 1 deer has been just fine but I’m still curious if I woukd be better off on deer sized game with the eldm.
