Surprising Results- Bone Stock Pre 64 Model 70... 300 yards.

[loudandproud]

I inherited my great grandfathers pre 64 model 70 a couple years ago. I've always shot boxed loads out of the gun. I have only ever shot it at 100 yards. The gun was always a 2 MOA gun at that range.

The gun is bone stock, only added a 3-9x40 Nikon Buckmaster scope to it.

I recently started reloading my rifle rounds. This gun is the first gun I have ever worked up a load for. The gun is shooting 168 grain Hornady A-max's pushed by 57.2 grains of H4831. CCI magnum primers... .105" Jump on the lands.

I saw some improvement at the range. The gun will now shoot around .75 MOA at 100 yards pretty consistently (presuming i don't heat up the stock barrel to high).

The other day I decided to take it out to 300 yards and see how the A-max's did at that distance.
Sent a five shot group down range and was amazed when I walked up and checked out the group.
A nice 1.105" five shot group. I thought it was a fluke. No way a 60 year old, bone stock deer rifle would shoot 1/2 MOA at that distance.

Today I went out to the range again. I ran a bore snake through the gun and shot a greaser at 300 yards. Then I followed up with a 3 shot group (one shot every 4 minutes).

Below is the result (The shot near the bullseye is from a different rifle).

With the greaser... .50 MOA.

Without ... .276 MOA

Is this a common occurrence for the old pre64's? Or do I have something special (for a deer rifle) here ?
This is the second session that this gun has shot this well, so i dont think these are me just getting lucky anymore.

its a 30-06.

And This one is has alittle too much sentimental value to get rid of.

Thanks though...

I have several Win M70 pre64's and they all shoot. The 300 win mag shoots the best.

we have two now. Both shoot "well", but this was better than expected.

The gun still only shoots around .75 MOA at 100 yards... Is it possible to actually become more accurate with distance (MOA wise)?

Yes it is possible. With boat tail bullets sometimes they don't settle down until they get some yardage on them.

I have taken a bunch of different stock hunting rifles made by Winchester, Remington and Savage and with free floating of the barrel and sometimes glass beading the action area with the proper handloads and had the same experience you have had with your Winchester.

I have had other rifles that no matter what you did to them they would not make a good tomato stake.
