I have just obtained that rarity a sako AI vixen in 6mm PPC USA - sporter repeater. It might get some use on the occasional deer but the twist is (as predicted by some) 1 in 14"

I am happy enough to use hornady 70gr sp's but noticed Nosler seems to think that 80gr BTs stabilise in a 14twist PPC.

Does anyone have any experience of what the accurate limit is? 80gr speer hot cores would be perfect......

Conventional wisdom (http://benchrest.com/sst/shilentwist.html ) says 70 grs max. Reality is, though, that it will depend both on the length of the bullet and the velocity you want to drive it at. If it was me, I'd try the bullets you'd like to shoot (you may already have some of them from your .243). The shorter, the better your chance that they might stabilize. Perhaps the Speer 80 grs will stabilize and shoot "well enough" for hunting... (although I doubt it will be your most accurate bullet).

Roes don't require much of a bullet. Perhaps even a match bullet might work for that application. Not that I have ever tried, but some people seem to get decent results with match bullets on light game.

Watch it, many of the lighter 6mm bullets are intended for varmint hunting (Nosler lists their light BTs as "Varmint" - even the 80 grs...). But you are probably aware of that, being an old hand in the 6mm game...

Try PM'ing Zaitsev (though he's not on here all the time), he's using Burgers in his Sako 75 VT and they really flatten things. They also come in a decent jacket so suitable for game.

Per my experiments, a 1 in 14" twist 243 barrel will stabilize a .935" long 75 gr Vmax bullet at 3000 fps out to 50 yards, but not to 100 yards.

What does it all mean?
The bullet must be shorter than .935", like a
.243, 85, Sierra SP 1520.... 0.910" long
.243, 70, Hornady SP 2410....0.793" long
.243, 80, Speer SP 1211......0.880" long

That's really helpful - looks like the 80gr hot core might be worth a try. I have 3 other 6mm to use any rejects in!

Try RB243P1 24/6mm .243 80 Power Lokt® Hollow Point in that 6 PPC for hunting .

The Berger 65 -68 match bullets shoot extremely well -try the varmint version .

The Nosler 70 gr balistic tip is also a very accurate bullet that expands well.

My 6 PPC loads use H-4198 and AA 2015 . The Sako throat is very long -seat the bullets give good neck tension .

A friend shot a 5 shot .21 group at 100 jumping the bullets .101 to the lands.

Try posting that question on Br.com -there are more than a few a few factory Sako 6 PPC posts .

That chamber is 6PPC USA -NOT to Benchrest specs and requires special dies from Forster or Redding .

Thanks again. Forgive me but who make the powr lokt 80gr HP?

I have a lee collet die set in 6mmPPC USA. Not fancy I know but I've had really excellent results with the collet dies.

1894mk2, If the rifle has the gloss finish and the European iron sights it is one of 35 which were the very first Sako's made in 6 PPC. They shoot amazing well and Sako used their "Olympic" barrels on them. I was successful in shooting the 80grain soft point "pistol" bullets and cannot remember if the 85 Nosler Partition stabilized or not... sorry.

Never should have sold that rifle...

My Hornady manual suggests using their 80 gr SSP (single shot pistol, part #2435 ) bullet in a 14 twist for deer. I have a box, and they measure .887 in length. They have been discontinued, however, but if you can find some, they may work

OK, Super Bon Bon, I will add it to my list and buy those too:

The bullet in a 1 in 14" twist must be shorter than .935", like a
.243, 65, Hornady Vmax........0.831" long
.243, 85, Sierra SP 1520...... 0.910" long
.243, 70, Hornady SP 2410....0.793" long
.243, 80 Hornady SSP 2435 ..0.893" long
.243, 80, Speer SP 1211.......0.880" long

Double, double, toil and trouble....fire burn and cauldron bubble... Here's an idea you might want to let simmer on the back burner of your mind for a while:

With all the bullets you are proposing to buy for trials, and thinking that you will likely want to keep and shoot that little Sako forever (and have 3 other 6 m/ms) consider buying yourself a Corbin set of 6 m/m bullet-making dies and a core mould.

They work very readily on any of the heavier reloading presses and are not expensive.

They enable you to make any length and weight of 6 m/m bullets you may ever want, so you can tailor your bullets to your rifle's twist. (Mine definitely shoot sub-MOA in a variety of rifles.)

You can also tailor your cores to a suitable hardness for your bullets and intended game, and you can even bond the cores into the bullet jackets for best penetration & expansion.

Best of all, you weon't have to ask Hillary's permission to buy bullets next year, or any year.

You can even make workable jackets from .22 Mag cases if you ever HAVE to.

I know that's likely not where you need to go right now, but keep the thought on your back burner. You may want a ticket to there sooner than we all hope.
