Can be and mine is. The saami spec seems to be for a short action. Best in a medium or long action. Gives you room to seat the bullet out and more powder space.

The reloading dies working ok B ?


They were extremely hard to find

Me?

Yes

Always good to see people using classic cartridges. Especially ones based on the great grandfather of all the 8x57 family and descendants.

I used a 8x57 on goats for years

Every time I fired it the rifle rang like a bell

Don’t even remember what it was but you couldn’t single load it

It had to be mag fed

They are good. I had some miss firing problems and found I was setting the shoulder too far back. My fault not the dies’.

It was a control feed action, the extractor encompasses most of the rim and won't pop over it the case needs to ride up under the extractor. I have a 9.3 and 3006 like that

This tread got me thinking. Just had my worn out 243 Majestic rebarreled in 257 Ackley

Nice, the push feed action a better option than the Mauser based Hunter/Viscount that I used. If I slow stroked the bolt, the round would hang up with the controlled feed.

Yes it is. Not sure if they do them anymore. Bought mine about 3 years ago.

Anyone using 2209 or 2213sc ADI powders in 257 Ackley, ADI's load offering seem very limited other than max load.

Yes Tetawa, I have data from my rifle.
It has a 25 inch tube on a 98 action.

In .257 cal pills 87 and less are varmit construction.

So 100 and above is the go.
In Win +P brass

2209 - 51.5 gns - 100 gn Nosler BT - 3300 fps.

2213 SC - 50 gns - 120 gn Speer - 2900 fps.

Start lower and work up, the 100 gn load is warm.
