8x68S loading data needed

[Ontario Hunter]

A friend just picked up an older very nice 8x68S CZ with some components and is looking for loading data. Any help would be greaappreciated.

My favourite caliber
Vihtavuori works great for me, also you could find some good recipes in the Hornady manual, the only one who take care of our 8x68
Also powders like IMR4350, IMR 4831, Norma 204 and MRP come to mind

I use 68gn of 2209 with a 196 gn projectile from the woodleigh manual, as posted by Phil Giordano. I like mine, one day I’ll learn how to post pictures on here

My 8x68s is a Blaser R8 and it has a pretty long taper or throat. As an example: with a 180gr TSX, the bullet hits the lands at 3.766”oal. I seat the bullet at 3.425”oal, that’s a pretty good jump. For bullet weights 200gr and lighter RL-16 and VV N550 have been my top performers. I think any 4350 class of powder would do well there. For heavier bullets, I shoot 220gr SGK and 250gr Woodleigh RN, I use Alliant 4000MR.

These are my loads for my rifle so precaution is in order.

180TSX @ 3.425”oal
WLRM
68.5gr’s of either RL-16 or VVN550
Velocity range is 3025-3075fps +/_

220gr SGK @ 3.425”oal
GM215M
68.5gr’s 4000MR
Velocity 2780fps +/-

250gr Woodleigh RN @ 3.54"
GM215M
67.5 4000MR
Velocity 2570fps +/-

I used my Steyr SM12 8x68s for the first time last month on croc in Africa. Here is the load that produces 1/2MOA at 100 yards out of my 8x68s:

Projectile: Northfork 180gr SS
Powder: 72.0gr IMR4350
COAL: 3.590"
Primer: Fed215
Brass: Norma
Avg Vel: 3053fps

Hornady also has some loads from its 9th Edition manual...see below:

Thanks. That's quite the club you're shooting. What are we looking at? A real beauty.

Tagging this thread for future reference, I keep buying brass when I find it.

I recommend Bob at ravenrockprecision.com for Norma 8x68 brass. Bob is a great guy and a supporter of AH. I have bought all of my 8x68 brass from him. I just checked and it looks to be in stock now.
