.277 matchkings?

Hey, just wondering if anyone had used the 135hpbt matchkings on deer or similar sized animals? If so how did they perform? And is this the best longe range bullet to use in this caliber? Thanks

Nope not me ...they are match not hunting bullets! Try some Accubonds and rejoice!

Re: .277 matchkings?

No, these would not be the best LR bullet for this cal.

I shoot 150gr SST's. Sierra makes a 150gr MK I believe.

The heavier the bullet, the higher the BC and that matters at LR. Just have a look at different bullet manf and you will see their wares.

Never shot the Accubond but expect good performance on target and game.

Re: .277 matchkings?

I'll second the ABs. I am shooting 58 gr MagPro with the 140 ABs. I have not been able to get any 150 gr bullets to shoot under 1.5" at 100 yards. I have tried six or seven powders to no avail. The 140 ABs go into nice little cloverleafs.

Re: .277 matchkings?

What velocity are you getting w/the 140s and MagPro. Am shooting 140s and 58gr RL-22.

Is magpro temp sensitive?

Re: .277 matchkings?

I shot it up to 3050ish, but was getting excessive pressure and overly compressed loads. The load that shot the best is just shy of 2900 fps. I'm not sure, but I think its going to be temp sensitive.

I am going to retry MagPro with the 150 NPs with a 9.5M primer instead of the GM210M primers. Its a slow ball powder, and its hard to get it all to burn up. I think the powder fouling was affecting my previous attempts with the 150s. I discovered how much fouling there was after the fact when I cleaned it. Just FYI.

Re: .277 matchkings?

As a long time .277 underdog shooter out at competition meets. (Nobody , but me ever shows up with a .277 target rifle) I have not ever seen the value in the 135's Logic should have told the manufacturer that 140-160 grain would have been a wiser weight. all I can think of is they were going for the standard twist rifles.

.277 dia. 135 gr. HPBT MatchKing .277 135 gr
.251 SD .488 @ 2800 fps and above
.482 between 2800 and 2000 fps
.440 between 2000 and 1500 fps
.390 @ 1500 fps and below
.277 dia. 150 gr. SBT .277 150 gr.
.279 SD .483 @ 2800 fps and above
.476 between 2800 and 2200 fps
.462 between 2200 and 1800 fps
.435 @ 1800 fps and below

Some of the above poster preferr the 140 sbt. I tumble moly coat the 150's and it increases the BC.

I also use mag primers and either R-22 or IMR 7828 powder.

.458 Barnes X 405 grain - 169.5 grain Wild Cat - 150 moly SBT and the end is a 140 Barnes x
