Anyone seen these? Anyone been testing these perhaps? Hard to believe they can improve on the regular matchkings.

.505 - .545

not a bad jump - I'd be interested in trying them out

What, no more fun with meplats?  Make the meplat trimmers obsolete?  How dare they.

I want to try them. They seem like a good long range bullet.

There are none in the supply system according to Sierra.  Supposedly some time after beginning of the new year.
Initially they are exclusive to BHA.

Cant wait to try them out.

HOT DANG !! I thought these were only going to Black Hills Ammo Co.

So glad these will be available for us !!

Can't wait to try these

I once saw a polymer-tipped (AMAX?) bullet that misfed.  The tip was totally mangled.  The damaged tip did not stop the shooter from firing the round but I don't recall if there was a problem with low POI.

Just bought a Savage .308 bolt gun.  I will be interested in seeing how these perform at the range.

It's interesting that every single one of those is directed at gas guns. 5.56, 7.62 and .300 BLK.

That's where the market is.



I sure wish they'd apply that to the 142 6.5mm.

I wish I could get excited about this ... but they are not new.  

Same thing as all polymer " Ballistic Tips " that get warped and misaligned in a magazine.

Probably better off with the old hard nose OTM's.

the only times I've seen deformed tips have been when the rounds were loaded longer then mag length or when seating the bullet in a case with a compressed load.  Both of those problems can be fixed.

Very true and as stated is an easy fix.

Honestly , I can say that I have never mangled a single Ballistic Tip type bullet through any auto loader.... M1A, AR15, AK 47, Browning BAR Mk II or SKS.

The best part about these bullets is the increased BC... the .308 TMK 155gr has a better BC than a .308 SMK 175gr... that means more speed.

And the ballistic gel performance is awesome.



.30 Caliber/7.62mm (.308) 155 gr. Tipped MatchKing (TMK)

New Product!

Sierra has enhanced a segment of the MatchKing line by adding the acetal resin tip, thus crowning the Tipped MatchKing (TMK) bullet line. The major advantage of adding a tip to the bullet is the reduction of drag, producing a more favorable ballistic coefficient.

The 155 grain Tipped MatchKing (TMK) bullet is an excellent choice for Palma and F-Class (FTR / F Open) matches, as well as 3-Gun and various other competitions.

Although the MatchKing line is recognized around the world for record setting accuracy, like their untipped counterparts, Tipped MatchKing (TMK) bullets are not recommended for hunting anything larger than varmints. The #7755 was introduced in January 2015.

Dia. (inches) Weight (grains) Sectional Density
0.308 155 .233

Ballistic Coefficients and Velocity Ranges
.519 @ 1900 fps and above
.490 between 1900 fps and 1600 fps
.420 @ 1600 fps and below


77gr TMK....







.22 Caliber (.224) 77 gr. Tipped MatchKing (TMK)

New Product!

Sierra has enhanced a segment of the MatchKing line by adding the acetal resin tip, thus crowning the Tipped MatchKing (TMK) bullet line. The major advantage of adding a tip to the bullet is the reduction of drag, producing a more favorable ballistic coefficient.  Another benefit is reliable feeding in magazine fed firearms. The 77 grain Tipped MatchKing (TMK) allows seating to an OAL that permits cartridges to be loaded into M16/AR15 magazines.



Although the MatchKing line is recognized around the world for record setting accuracy, like their untipped counterparts, Tipped MatchKing (TMK) bullets are not recommended for hunting anything larger than varmints.  Having heavier jackets than our Hornet or Blitz line of bullets, these bullets will not provide the same explosive expansion on small varmints. The #7177 was introduced in January 2015.



Please Note!! This bullet requires a 1x7" to 1x8" twist barrel.



Dia. (inches) Weight (grains) Sectional Density Ballistic Coefficients and Velocity Ranges

Both of those show outstanding ballistic gel performance.

Very glad these are coming out to the market so us hand loaders can try them out.

It is a lot easier to make very uniform plastic tips than metal tips.

I remember shooting these back in the 90's.

I wonder how well the 125 will work for .300blk?  Eager to try a box

looks like a secant ogive on these vs the tangent ogives on the regular mk's

price them at regular smk price and I'll give them a try

I ordered a couple boxes of the 125gr and 77gr to find out.

This is from a buddy who's used the BHA MK262 clone with the 77gt TMKs in place:

I got a case of the Black Hills 5.56mm 77gr TMKs and have shot them at 200yd and 500yd.  Initial results are impressive, and the G1 BC of 0.420 seems to be legit.  They seem to group a little tighter than the SMK/OTM rounds, but that could be just my perception.  I did have one 5-shot group at 500yd that measured less than 6", which is better than anything I've been able to shoot before.  Could just be coincidence/luck too.

 

Please post your findings!!!!

For reference.... (.308 bullets)

Sierra 168 Grn TMK BC = .535
Berger Hybrid 168 Match BC = .519
Hornady 168 AMAX BC = .475
Sierra 175 HPBT SMK BC = .505

.... also the Sierra 155 Grn TMK BC = .519..... same BC as the 168 Berger, and higher than the 175 SMK.

I see them selling boat loads of the 155's and the 168's.

Will there be a 175gr tmk?

Yes, there is.

Those 155s can be launched nearly 3k fps out of a 24" gun...

They made these for the Palma shooters.

Seeing how they are shooting 155 at 1k they needed something with a high BC to compete with the AMAX.

They might even use them for the military as the OTM were questioned as hollow points

Nosler figured out years ago how to effectively put plastic tips in bullets, and everyone has had to work around their patents.
The first round of Amaxs had some bad bad problems.

What's really crippled Nosler had been their archaic bullet designs with regard to their form factor.
That's only recently changed with the LR Accubonds, and it's still not what it could be.

Indeed.

Well, it took Sierra how long to do this? I wish Nosler would make a cheaper version of the Accubond LR. Use the same dies as the Accubond bullet, but in a cheaper cup and core design.

7mm 150 gr Nosler Accubond LR
G1 BALLISTIC COEFFICIENT 0.611
G7 BALLISTIC COEFFICIENT 0.309

That's a really slick bullet in the 7mm line if it shoots well in your gun.

Sierra has a pretty comprehensive ballistics lab, and I bet A LOT of work went into getting these bullets where they shoot well.

I also have a box of older Nosler Accubonds that the tips are disintegrating out of. Strangest thing...
I'm sure these will be good bullets, and I'm excited to see where they go with it.
I want it applied to the 123 and 142 gr 6.5mm billets.

As my Avatar might indicate, I like using polymer tipped bullets. (150 Grain .308 Nosler Ballistic Tips Shown)  

They are consistently accurate and anything I've ever shot with them went dead.  To be fair, every bullet, properly placed, will do that.  It's just that I I've had success with these.  I will definitely try this new offering from Sierra.

These are the bullets I use exclusively in my .308's.  I've fired thousands of these bullets from 5, 10, and 20 round magazines - both steel and polymer magazines - and I've have never had a failure to feed or failure to eject as mentioned elsewhere in this thread.

When I get them I will post up results.  If they shoot as good as the regular match kings I will be happy,  my Mk 12 clone love them.

I've seen enough Hornady AMAX bullets lose their tips and fly off target in a match that I will hold off on these until the hardholders report them GTG.

I'm thinking the 155gr TMK might be the hot ticket for 16" AR's.

I still have a bunch of the 100 ct boxes left. A few of the 50 ct boxes also.  Probably 13 or 14 boxes of the 100 ct, 5  or 6 of the 50 ct..
