Sisco Posted December 19, 2014 Report Share Posted December 19, 2014 Able to maintain supersonic speeds to 1000 yards in 308. These are gonna be hot. https://www.sierrabullets.com/store/product.cfm/sn/7775/308-dia-175-gr-Tipped-MatchKing-TMK Quote Link to comment Share on other sites More sharing options...

mineralman55 Posted December 20, 2014 Report Share Posted December 20, 2014 So I have to wonder, is it just the resin tip or is there an improved shape to the bullet as well? Hornady makes the A-max (okay, in 168 grain) but they've never claimed it supersonic at 1000 yds. Quote Link to comment Share on other sites More sharing options...
Sisco Posted December 21, 2014 Author Report Share Posted December 21, 2014 They say the resin tip improves the ballistic coefficient to enable the bullet to maintain the ability to stay supersonic to 1000 yards. Guessing it would be an extremely hot powder load. I like my AR10's and I worry now about long term use of M118LR after I put it on a chronograph and saw how hot it was.The bullet is only one variable, so I am guessing it could, but I probably wouldn't unless I was the Army Marksmanship Unit and had a squad of full time armorers to service my weapons. The Hornady could probably do so as well but at what load and what long term price to your weapon? As the TMK is out a while we will get more info on recommended loads and we will see just how better it is. Quote Link to comment Share on other sites More sharing options...
NTXshooter Posted December 21, 2014 Report Share Posted December 21, 2014 That's great if you are shooting paper or steel, but all my loads are destined for hunting. Those aren't made for hunting. Quote Link to comment Share on other sites More sharing options...

Brother....that's why these things are "modular". So we can replace parts that wear out. That being said, You're like me........an Armalite guy. That means your stuff will never wear out <laughs>. The competition will start complaining shortly. <lmao> They're just jealous. :hornet: Quote Link to comment Share on other sites More sharing options...

Look up "Awesome" in Webster's Dictionary, and there is a picture of an AR10. Quote Link to comment Share on other sites More sharing options...
Rsquared Posted December 23, 2014 Report Share Posted December 23, 2014 That's why they both start with the letter A my man. That way, they're both front and center of ol Webster's book. Quote Link to comment Share on other sites More sharing options...

Try Sierra's Gamekings. Look just like a BTHP but better. I've actually found them to be just slightly more accurate. Quote Link to comment Share on other sites More sharing options...

Your right there, a helluva of a bullet for hunting, and accurate. Quote Link to comment Share on other sites More sharing options...
N Jensen Posted December 26, 2014 Report Share Posted December 26, 2014 The tipped 168 went from .463 to 535 BC, so I would think they would be good for 1,000 yds when in the past they were not. They also very close to the 175 tipped bullet. Probably shove the 168 down the barrel a little quicker than the 175 as well. The LR M118 is pretty warm load and will cycle the BCG very fast. I bent my bolt stop when shooting them. The reason why they are so hot is because the LC puts a tar like glue on the bullet sealing it into the neck of the case. This makes the powder burn more and produce more pressure to break the seal. The pressure curve goes up very quickly. One way to prevent this and help lower the pressure is to place the round in a bullet seatter and break the seal, just seat the bullet a little deeper, say .015 Quote Link to comment Share on other sites More sharing options...
