Hey Bruce!

You might try to contact 762nato on Gun Nutz. Andy has loaded some of this, and his one group that I watched him shoot (five rounds rapid fire at a hundred yards, iron sights) was as good as I can do with a scoped modern rifle. Of course, that is not saying much.... but it was solidly 1.5"........

I've been using Lee dies - have FL, collet, seating. .284 brass FL sized. Nosler 150 Ballistic Tips which were on hand, Fed. GM primers, and a moderate charge of 4895 out of the manual. Going to try some 178 Amax later on. Cases form very easily. Accurate.

How do I go about changing the 284 brass to 7.5 brass?

Tiriag:
You'll like the 178gr Amax.


100 yds is pretty close, so bullet choice is not too critical at that range. The further out you go, the better a bullet you'll need.

I've settled on 178gr Amax and 44gr Varget, until I get more opportunity to test other powders and bullets. I have F/L dies from Lee, RCBS and Hornady's New Dimension in 7.5x55. I prefer the Hornady, but the others are usable too. The Privi brass does have to be trimmed too.
Use good lube. I had stuck Privi brass in the RCBS sizer when I tried Hornady's One Shot pump bottle Lube. With the Lee dies, the de-capping pin could be used to drive out the case, whereas I had to remove the RCBS dies, drill and tap the case(1/4-20). Save yourself the trouble and use good lube to start. I'm using castor oil now.

which swiss do you have?

There is a slight difference between the models.

These rifles are zero at 300M, use this distance to check you loads against mil surp ammo-[hard to beat!]

Redding makes dies that are set up for the k31 Swiss.

Norma makes ammo or components :
powder ( norma 203-B, 204 and MRP)
brass cases &
bullets -{standard .308 inch} (9.7 g Norma FMJ, 10.9 g Sierra MK & 11.7 g Norma Oryx) for Swiss 7.5 by 55mm

I can pull 2" groups with my 7.5 off the hard rest with little effort, thing just plain shoots straight-SDH

[K31]

Just run it into the 7.5 die, and trim to the proper length. But why even bother, when Trade-ex has Privi Partizan 7.5 Swiss brass for less than you would pay for .284?

I agree. I've had good luck with Prvi brass. Either brass or loaded ammo Graf & Sons - 7.5mmx55 Swiss .

If you are only loading for one K31, you can just neck size with a Lee Collet Neck Size die. Get much longer life without stretching the brass everytime.

I've got 0.8" groups, five shot, 100 yd. off crossed sticks with my own cast bullet (RCBS 165-SIL) using Reloder 7.

Aren't the Lee dies cut for the K11 rifle, while the Hornady/RCBS cut to the K31 standard?

Most loads for the 308 should work well in the K31...
