New 6mm and 6.5mm Tipped MatchKings from Sierra
Sierra has released two new Tipped MatchKing (TMK®) bullets that should find favor with PRS competitors and tactical shooters*. Sierra is producing a new 95 grain 6mm projectile and a new 130 grain 6.5mm bullet. Both feature acetal resin tips that lower drag by improving the ballistic coefficient (BC) and making the BC more uniform from bullet to bullet. The 95-grainer should work well as a higher-speed option in the .243 Win, 6mm Creedmoor, 6mm Dasher, and 6mmBR. We were able to push other 95gr bullets nearly 100 fps faster than 105gr bullets from a 6mmBR. For those shooting the 6.5×47 Lapua and 6.5 Creedmoor, the new 130gr TMK should be a near-ideal bullet weight. We know that Berger’s 6.5mm 130gr VLD works great in those mid-sized cartridges, so Sierra’s new 130-grainer should be in the “sweet spot”. Also, in the .260 Remington the 130gr TMK should be capable of velocities that hit predicted accuracy nodes with ease. The 6mm 95 grain TMK requires a twist rate of 1:9″ or faster to stabilize while the 6.5mm 130 grain TMK requires a twist rate of 1:8″ or faster to stabilize.
We expect the 130gr 6.5mm TMK to find favor with Tactical Shooters
* In addition, Sierra plans to add a 7mm 160gr TMK to the line-up, product #7660, but we don’t expect this to be used for tactical games because of the heavier recoil.

When are we going to see a 140 or 142?
95 gr. is too light to be useful in PRS. Most matches have a 3150 fps. velocity limit. You can already exceed that or come close to 3100 fps with a 105 Hybrid in everything but the Dasher and the 6BR.
They should have released a 105 to compete with the 105 Hybrid.
Kris I believe the tipped 107gn Match King competes with the Hybrid.

I wouldn’t say the 107 Match King competes with the 105 Hybrid when 80% of the shooters in last year’s finale were using the Hybrid and no one was using the Match King.

Opps! That was the overall statistic, which included both 6mm and 6.5mm bullets. Of the 28 shooters who made it to the finale and used 6mm, 27 of the used the 105 Hybrid. One used a Scenar.
If they offered a 105-115 gr. TMK, I bet you would see some Sierras in the stats.
btw, the BCs on the 6.5 don’t seem to have gotten mixed up. The BC should be highest at the highest velocity.
There’s also a herd mentality with bullets when in fact there’s other fine choices as well. You see that with powder too. Look at varget and the palma shooter, its ok but there’s other choices that work very well also. Specifically the 107 will keep up with the 105 all day long, anyone who has shot both bullets can tell ya that.
I still think the US market does not understand the peak point where the 6.5 shines and still treats it like a slightly bigger 6mm.
The 6.5mm is a chugger not a speed demon. Push it along at 2800 with a heavy 140 plus weight bullet and it becomes boringly accurate with low recoil and long barrel life.
Would love to see move variety in the 140 to 150 weight range.
Your absolutely right Kris the Berger is a definite favourite judging by those stats, what I meant was I think the 107 is ‘Sierras’ equivalent to the 105 Berger.

What I don’t understand is that Sierra’s 6.5 123 MatchKing has an advertised BC of 0.510 which is actually corrected by Litz independent testing to 0.522. Why, then, would anyone go with a heavier bullet with a lower BC AND lower muzzle velocity? And why wouldn’t Sierra use a state-of-the-art hybrid ogive design? (Unless they actually are — but the photos look standard tangent to me.) In light of Berger’s 0.560 BC 6.5 130 hybrid OTM, I’m underwhelmed.
