sub MOA at 15 F

It was a balmy 15 degrees this afternoon. Slight breeze in my face.

I had 9 loads premeasured. 4 ea 8/60 4759/4198
4 ea 10/60 4759/4198
1 ea 10/40 4759/Varget

.458 300 grain Hornady #4500 with HPH24 sabots. Load pressure runs at 85 pounds to get past the QLA 70 pounds travel down the barrel and over 100 to seat. Not for everyone, new experiences have shown the folly in leaving the bullet starter on the bench in the basement.

The ML has one wet with Hoppes patch over a bronze brush run through followed by two dry over the same brush. I did not dip the brush only the patch.

!st shot 2322 fps approx 5 inches high. Typical for my ML to shoot high when clean.

2nd and 3rd shot 2331 fps

4th 2322 fps

Shots 2,3,&4 7/8 inch ctc

Adjusted scope 20 clicks to right and 8 back to the left. I needed 3 inches to the right.


10/60 loads

1st shot 2398 fps
2nd and 3rd 2411 fps
4th 2415 fps

Discounting the first shot, I normally do this, experience taught me that most scopes need a shot to seat the erector tube after adjustment. I shot a 3 1/4 high by 1 3/8 wide group.

I was happy to see that accuracy fell off with the stouter 10/60 loads. I am not sure if I met Kerry's definition of high recoil or not. I will count my teeth in the morning. The 8/60 loads were not bad. The tuperware stock has a way of coming up under my cheek bone.

The 10/40 4759/varget was a whim mostly because the powder was on the bench. However it achieved a respectable 1633 fps. The Varget is a strange powder that seems to work fairly well with many different centerfire loads.

Substitute 5744 for the 4759 in that 10/60 combo and you can gain another 60 fps and really jar you teeth loose ;D

That Varget works great in my 40. I normally use 7/63 of 4759/Varget with a sabotless 200gr bullet. Accuracy is outstanding and it gets pretty good velocity (~2750).

You should be able to use a bit more of it than the 4198 in that 50. Check some of the posts on the old board for 50 load data and you should be able to find a combo with Varget that will rattle your cage pretty well.

Sounds like you are getting some good results with your load experimenting.
7/8” CTC is not shabby at all.
Good shooting.

Did you have to adj. the scope because of cold or was it off to left for another reason?

[youp50]

Just dialing in a different scope. I normally have a 1.5-5 Leupy on it. Mounted a 2.5-10 Monarch on for range work.

I just hope that falling shot string does not indicate a mechanical problem.
