From Pac-Nor:
Your order is 1)338 10T sssm Rem Sendero contour 26" Fit and chamber for Rem 700 338-06 ACk FB crn, BB finish

I am looking at buying some dies, I have gotten confused with all the web stuff. The Pac-Nor 338-06 AI is a 40 degree shoulder but, I keep getting references to the 338-06 A-Square? How are the two different? Are they both the same with a slightly different shoulder location (seems like there are some minor difference in what A-Square standardized and a traditional Ackley Improved version)?

These are the dies I found on the RCBS website: 56397 - .338-06 IMP 40d F L DIE SET. Are these a good choice or, should I look somewhere else?

Thanks!
Sid

The 338-06 A-square is simply the std 338-06 with their name added to it when they SAAMId it. It retains the std 17deg 30min shoulder that the parent 30-06 case has. You will need dies for the 338-06 Ackley which should be available from the likes of RCBS, Hornady, Redding or CH4D. The ones you linked from RCBS should be OK, perhaps confirm with them that they are right for the AI round, they sound like they are.

Websites like this tend to confuse things:

Ackley or A-square at Midway?

They list everything as Ackley Improved and A-Square but, they have different shoulders.

This is what I have used for the last 10 years.

Sid,
Yep.. there's several differnt ways to AI a round, and most of th etime the shoulder angle, or neck determines the differences... and, with the 338, it's 50 max fps

At equal pressure.

A little off topic, but I was looking at some 338-06 Barnes data tonight and they seem to use a 210 magnum primer in many of their loads. I was just interested if anyone does that here? Or do you use regular primers?

My 338 is a wildcat. More like a Gibbs around 11% capacity gain over a 338-06. I use a magnum on a couple powders but normally stick with a std. I get better accuracy in my rifle.

Both Barnes #3 and #4 use mag primers for their testing. I worked up a load for 225 X flatbase bullets for plains game using a case full of spherical H414 and used standard primers with no problems.

Mag primers are usually suggested for really cold weather or spherical powders. Barnes's recipes list a majority of spherical powders so perhaps that's why they used mag primers for all their testing.

Ty Herring @ Barnes customer service could give you the answer.

There is nothing wrong with using a magnum primer on all cases the size of the .30-06
