Thread: 30-06 Akley improved load development

The SD over 2 or even 3 shots is meaningless I am fully aware of that. The charge weight loads were merely to check where I was at with velocity as there is very little published load data for the Ackley.
I needed to see if I could obtain the velocity with the powder and projectiles I chose, before committing to loading more.

Yup hence I'm purely making a suggestion regarding SD nothing else

I'm sure your rifle may shoot it fine and you may not have the traditional tell tale signs (heavy bolt, flat primers)these are not always present when over pressure.
I've always said velocity is the best indicator of pressure.

Greeting again,
I believe that the Sako Blade projectile is a monolithic so will need a lighter charge and will develop less velocity. Max velocities for the Barnes and Hornady GMX 165 grain projectiles top out at around 2,800 fps in the vanilla 06 with around 55.5 grains of AR2209 so I would not go past your current load for that projectile. As @Dicko suggests the 165 grain Nosler BT will be your best bet for top velocity. You will likely need around 60 grains of AR2209 to match his velocity.
GPM.

My weatherby Ultralightweight 30.06 didn't like 2209 it did shoot better groups with 2213sc. 2.5 to 3'' groups with 2209, 1'' with 2213 with the same projectiles.

Right on the money good sir

Well today was an exercise in frustration and futility erratic grouping, erratic velocity spreads, nothing worth looking at.
Got home and had a look down the barrel, now I've never copper cleaned this barrel but I'd suggest it's probably had somewhere between 200-300 rounds down the tube tops. I could see copper in the rifling at the muzzle, I gave it a quick 15min soak with bore tech copper remover and this pic was taken after that



Currently it's having a longer soak, hopefully I can get it cleared up. Then I'll load some ELDM's with my old recipe that always shot well in this rifle and see where we are at.....

So what were the results?

Literally nothing of value and nothing grouped better than 3"
Was it the copper ? Who knows ? Either way I'll get back to known territory with my old recipe once I've cleared the copper out of the bore.
Currently on it's 3rd with bore tech, might have to get some jb bore paste if it doesn't start shifting the copper.....

That looks like a solid lump of Cu. Boretech should clear it out for you.

Yeah that was after the first soak.....currently on its 3rd. It will come clean it just needs patience and boretech

Curious to see how it develops.

Me too, I'm nothing if not persistent....I will get it shooting right again

Well this morning I went copper mining.....after 3 soaks with boretech copper remover with almost no improvement, I got hold of some JB bore bright (game changer ) 10 minutes later bore free of copper.
I'll get some more rounds loaded up today and hopefully get to the range tomorrow.

Loaded up 15 rounds of my old recipe with 178gn ELDM's hopefully tomorrow accuracy returns
Got a few Bergers there I'll try again now the bore has been thoroughly cleaned of copper too.
Fingers crossed, the copper fouling is probably the worst I've seen.
Prepared that it may take a few rounds for the barrel to settle in again.

See how your speeds are. You could have a carbon ring just in front of the neck in the chamber which impedes the release of bullet and cause variations in pressure spike .

Are some of those loads compressed? Looks like projectiles have taken a bit force to seat.
