Yes it is match king,The biggest thing we have here is deer so it works fine on them. Haven't got my notes handie right now but I think I have it going around 3000fps with the 62 grs,max is around 67 grs.
Used a tsx on a hog last year and it worked fine also.Have used the sst on several deer and they work great too.
The sierra game king BTHP140 shot the same poi as the 135 gr.shot one @250 yds with it the deer dropped at the shot,when I went to get it,it was gone only a big blood puddle,found one drop of blood about 4 ft from where it dropped nothing more, five of us looked for it for 2 hours,hate it but lost the deer.Don't think the bullet opened up,found out later they are more for larger game.
Let my younger brother shoot one at 200 yds with the BTHP 140,I watched through field glasses,seen the bullet strike behind the front shoulder the deer took off didn't find one drop of blood or the deer ,so won't be using the game king BTHP any more but the game king SP should work fine.
The game king BTHP may work fine at a higher fps but there are too many other good bullets to use on deer here without the risk of looseing another one.
