M28/76 Asev1 sniper

[Farmerboy78]

Guys, thanks to a couple great members here I have been able to acquire this rifle in its present state. It's a d166 marked barrel and I even have the diopter sight setup! It has what appears to be a M85 ring and trigger installed and I have to say this trigger is great. I wish I had the bipod for it, but until then I'm using a versapod. So the M85 rings are 30mm and this scope is 26mm so I'm using shims to mount it.

So does anyone have a load that will match the turret? And how do I zero out this turret?

Looks great,

Interested to hear how the scope is zeroed.

The scope has a centered reticle that do not move in the field of view.
Loosen the two small screws on the turrets and zero the rifle on 100m using the coin slots just as on any Leupold (except cw adjustments)
Turn the loose BDC cam and align the "1" with the white dot below the bdc-cam. Tighten the two small screws.
Same procedure for the vindage.

There is a very noticeable "click" for ever range nr and every 50m above 300m. This lets you adjust for range in the dark, in the cold with heavy gloves with a gasmask. No other scope let you do this. There are no clicks between the range numbers and 50m markings above 300m.

I used the same scope, a S&B 6x42, on a Kongsberg M59 (M98-based) rifle in the National guard. It's a bulletproof scope. Used one for 20 years on a hunting rifle for caribou and another one on a Winchester M14.

I would suspect that used the D166 load which is a Lapua D166 200 gr bullet at around 2250 fps.

I am 97% sure the cam on that scope is calibrated for 7.62NATO ball with 147gr bullets in 24" or longer barrels.
The cam for 168gr and heavier bullets usually only go to 600m due to the amount of elevation in one turn on this zero stop turret.

 

[Farmerboy78]

So I may get to drive it a little faster. I have 150gr mono .311 to d166 200gr

The correct round for that rifle is going to be the D166. I don't know if the scope will match that trajectory.

I would also try some Yugoslavia heavy ball 180 grain stuff. That might be really close to matching that scope.

The turrets on that scope feel solid.

If it had not moved I was considering it for an MC1, M1 Garand sniper build as a stand in for a Kollmorgen 4X MC1 scope.

The profile would have looked similar. But I doubt the drop cam would have matched 30-06.

Guys I have been doing some reloading prepping for some load workup for this rifle. I used the .311 190gr ppu fmjbt, the .3105 174gr hornady fmjbt, the .3095 d166 lapua, and the .311 150gr lehigh defense monolithic. I had several 1 moa loads with all these bullets but a few really stood out to me.

Here the the best 190gr loads

 

[Farmerboy78]

Next I worked with the 174gr hornady with these as the best results.

 

[Farmerboy78]

Then I worked with the d166, which nearly every group was moa or better, but with 2 outstanding groups.

 

[Farmerboy78]

Finally, I worked on the .311 150gr lehigh copper mono bullets and was getting frustrated until I made it to the last load where things came together.

 

[pmclaine]

Great job!

Post reticle would not be what I consider ideal for groups.

Those look good.

 

[Hetzer]

What did you load for those D166 groups?

 

[Farmerboy78]

Lapua brass, d-166 bullet, wlr primer, 38.0 gr and 38.4gr of varget
