Many times at the ranges I visit there are people trying to adjust their scopes for the hunt.
I help out if they look like they want some help.
Lots of them shoot Remington box ammo that they picked up at Wally world.
Now I have had No luck with this ammo except in a 336 30-30.
Most groups I see from the 308's are in the all are fliers range MOA of slice of bread if you are lucky.
I have given these guys some of my handloaded 308 ammo to try and groups shrink to 1"-1.5" or really close to that.
So one guy headed for a hunt in 3 days was not happy and I gave him 4 rounds of my accurate hunting ammo we just tested in his gun to take hunting.
Yes I lost 4 Lapua cases.
But I got in trade 4 cases of factory loaded Remington 150gr ammo.
I finally took it apart today and measured things to see why this ammo was not accurate.
Long story short I feel it is just not a good charge weight.
Details.
Powder looks just like BL-C(2) but not as shiny (it is more dull grey).
Powder comes to the base of the shoulder(not compressed)
Charge weights were: 46.4gr., 46.3gr., 46.3gr., 46.25gr.
Bullet weights. 150.9gr., 151.4., 151.4., 151.3.
Neck OD after pulling bullets with inertia puller all the same .335"
Neck ID 3 at .308" 1 at .3075"
Measurement to shoulder datum within .002" of each other.
Case base sizes all exactly the same.
Case weight with primers. 170.7gr., 171.2gr., and 2 at 171.7gr.
Trim length 2.05-2.07
The bullet after being pulled had scratches on the bearing surface it is a flat base spitzer with cannelure.
I did not test how much pressure it took to pull the bullet from the case as this would make powder fall onto the floor and i need to drill a hole through the bullet to do so.
So looks like the stuff is pretty well on as far as tolerances go.
When i worked up loads for my .308 with Ball C2 powder and 150gr flat base bullets
I used Winchester brass and charge weight that worked was 45gr.
So maybe it is just not an optimum charge weight for the guns I have seen it shoot out of.
I was thinking the factory loads in that Rem yellow and green box were just not in good tolerances.. I was mistaken.
