For Sale: Sierra 77gr .224 Matchking Bullets with cannelure

[Mousegunner-UK]

A fellow shooter and I have managed to get a job lot of the Sierra 77gr .224 Matchkings with cannelure. We're keeping our own supply & selling the rest at £180 per 500 (Kranks RRP is £233.30/500 so our price is well under the RRP)..

(They came boxed in 2,500 bullet bulk packs, so will be split into a separate bag unless you want a whole box!)

The cannelure version has the same sectional density and BC as the non-cannelure version, so load data is the same.

For those that don't know the cannelure exists due to the US mil/gov requirements; its only purpose is to stop the projectile from moving due to extreme handling, e.g. being dropped, falls, etc. The cannelure ring provides a nice spot for the crimp to grab on to.

For the civilian world, it doesn't make a difference at all.

I've been using the 77SMK before the US military “designed” the Mk262 which now uses the cannelure bullet.

There is zero change on flight characteristics; think about it once a non cannelure bullet leaves the case and engages the barrels rifling it has numerous full length deep rifling grooves on it - much deeper than the very light cannelure on the 77SMKs being sold here.

The bullets can be posted at cost, brought to Bisley at a CSR/HRA match, or collected from Chessington or Wimbledon.

these are usable without crimping right?

Yes, I use the 77 TMK with and without Cannelure and the shoot they same. And do not crimp,

Great bullets. I've used both types out to 600 and there's no difference in drop/drift or accuracy.

If I didn't have plenty, I'd be buying some of yours.

Sierra say 1:8 or faster, so they would be stable ok.

What powder is best in a .223 with these bullets.

 

[Mousegunner-UK]

I’m using Viht N140, 24.6g (though N540 can also be used); I also use Win Staball Match, 24.8g. It all depends on what’s available at the time. But as with other load data, start lower and work up till you get best group/velocity/pressure combo for your gun, you may end up with a lighter or heavier charge than what I am loading

I use RS52 with good results.

What barrel length and twist is that?

 

[Mousegunner-UK]

What barrel length and twist is that?

18” 1:8

 

[RJ156]

Gonna say, I’d have thought anything long like 24” would be a bit hot on that sort of charge of n140

 

[shoppe]

Viht 140 with charge of 24.something is pretty much the go to load for 77grain match kings.
