Sierra Tipped MatchKings - BC test results

Since Sierras announcement of their line of Tipped MatchKing's, I've gotten a lot of requests to test them for BC. Below are my findings for the 4 out of 6 bullets I've been able to acquire and test so far.


Sierra's BC's are measured by live fire, and are typically pretty accurate if the velocity bands are properly observed (7mm being the exception). A common error is to look at the BC that Sierra gives for your MV and just use that. Doing so overestimates the performance of the bullets, and will cause you to hit low at long range compared to your trajectory predictions.

As you can see from the table above, when Sierra's G1 BC is averaged for all speed ranges (which is representative of long range shooting) the results closely match the Applied Ballistics measurements of the same bullets averaged from 3000 to 1500 fps. Of course the G7 BC doesn't suffer nearly the velocity sensitivity as G1 and should be used for modern long range bullets when possible.

When I get the .22 cal 77 gr, and the .308 cal 168 gr tested, I'll update the table.

BTW, for those interested in how these Tipped MatchKings compare to the standard MatchKings; according to my measurements:
The 69 gr TMK is +8% compared to the SMK
The 125 gr TMK is -5% compared to the SMK (which I believe was 'pointed' not tipped)
The 155 TMK is *identical* to the 155 SMK (2156, which is also pointed)
The 175 TMK is +10% compared to the 175 SMK

Take care,

I was curious about the improvement in BC value on the tipped bullets versus the un-tipped Match Kings. The BC values versus velocity ranges provided aren't identical. Still, it looks like a decent gain in BC value. I believe the Tipped Match King BC values will be more consistent from bullet to bullet, and that the Tipped Match Kings will expand more reliably on game than the non-tipped Match Kings.

Here's the BC information I collected from Sierra's website for two of the .308 bullets. And here's the Sierra website link to the source of this information: Ballistic Coefficients - Sierra Bullets - The Bulletsmiths
Simply select the caliber bullet you're interested in researching into the drop box provided at their website.

Any news on the 168 TMK?

I've shot the 175s to 600 yards with stellar results. I've only shot the 155s to 300 with reasonable results. Will try them at 600-700 next.

Going to start load development this week on the 168.

The 69gr .224 TMK is getting close to the 77gr SMK, and the 175gr .308 TMK is really nipping at the heels of the 190gr SMK (using bc #s taken from "Modern Advancements For Long Range Shooting"). Awesome, keep up the good work Bryan!

Been wondering about those thins since the first time I saw them. Its great to hear they live up to the claims!
