Sierra Heavy TMK 6MM Testing

[Formidilosus]

Form, if i may just clarify. prior to these for 6/243 you recommended 108m over 115 dtac mostly due to neck length and less favorble tumbling at distance in smaller animals which makes sense.

Yes, that was correct. The 95gr TMK was not available, and the 108gr ELD-M and 103gr ELD-X were the best option generally.

These certainly scale up from the the 77s and understand your current affinity. For a 6/243 and choosing between the 116 and 107 - if its 95% deer sized game and one (read hopefully) elk annually are you all in on 116 regardless of game size since neck length is a non issue?

Yep. The 107gr is good too, though not as much use in it yet- but the 116gr is fantastic. In a 243/6cm/6xc size cartridge with a short barrel it’s easy to use straight quick drop or an easy correction factor for it.

secondly, exits are nice but it hasnt been an issue for me yet. but am interested in your exit comparative or thoughts of the 107, 116 and prior experience with the 108m at all distances. I believe you have noted a couple of times about getting exit(s).

All the 6mm TMK’s seem to exit more than any other save the DTAC. Haven’t caught a 95gr, 107gr, or 116gr yet- though haven’t used the 107’s and 116’s on elk.

108gr ELD-M’s are variable more than I prefer. Some lots of buckets are devastating, some lots are more controlled wound channel size, and both every once in a while will have a bullet not upsetting, or minimally so.

The two whitetails I recovered last year with the 95tmk’s caught both bullets.

One 20 yards quarter-to high shoulder that seemed to catch most of bullet in cavity and spine. Didn’t open cavity to search it out, but found small fragments in offside hide.

The other 75 yards broadside mid body caught spine. Recovered Bullet in offside hide, probably 40-50% weight retention.

Both in the 24-2600fps impact velocity range.

Only two samples to offer with the 95’s so I can’t pattern it.

This nails it. Personally I’ll run the 107 in my 6ARC but lean toward the 116 for a short barreled 6CM/243, for exactly this reason. MV in the 2600fps range makes quick drops way easier than when it’s up at 2800 or higher.

…can load the 107 down too though.

I don’t think anyone will complain with the wound channels from either.

Oh, I bet some will, just not about the wound being to small…

Ain’t that the truth.

"You can't kill them too dead..." Or something like that.
