Default "The Load" Mod 2 - short range, reduced recoil precision

- 125gr Speer TNT
- 16gr VV N32C
- Sized, trimmed, flash hole uniformed, virgin Hornady .308 brass (ID 0.305", loaded OD 0.337")
- CCI 200
- OAL 2.700" +/- 0.005"; at least 0.12" jump



Pre-'64 Winchester Model 70 Target with 27" Obermeyer 5R 1:10, Redfield apertures, bipod and rear bag support. Bore was moderately cleaned last week before 60 rounds in a match, and 5 rounds right before this test.



Temperature in the 70s-80s, 5-15mph tailwind, partly cloudy. F1 Shooting Chrony set just shy of 15ft from the muzzle. I have not tested the calibration, but believe it to read 100-150fps fast.



1st string:
Shooting position wasn't quite right.
1816
, 1860, 1859, 1854, 1862, 1853, 1858, 1856, 1851, 1836
Avg: 1851 fps
ES: 46 fps
SD: 13 fps

Minus the outlier -
Avg: 1854 fps
ES: 26 fps
SD: 7 fps





2nd string:
Shooting position mostly fixed, bench is a little high.
1784
, 1853, 1846, 1845, 1845, 1833, 1856, 1862, 1862, 1855
Avg: 1844 fps
ES: 78 fps
SD: 22 fps

Minus outlier -
Avg: 1851 fps
ES: 29 fps
SD: 9 fps





Combined:
Avg: 1847 fps
ES: 78 fps
SD: 18 fps

Minus outliers -
Avg: 1853 fps
ES: 29 fps
SD: 8 fps

It might like a little tweak, but it could clean the MR-31 with a high X-count as is, so it's not worth the patience.

Did I miss something in your post? What distance were those targets shot at?

I would guess he is shooting 100 yards if he thinks it would clean an MR31

First of all, great rifle! It is the sort of setup that I've always thought would be ideal.

Next, tweaking. Yes. Fiddling around to get a load as close as possible to perfect is just always worthwhile. It pays off when you are no longer practicing but rather are actually on the firing line in a match or shooting in the woods/field. Especially in the woods/field precision really does matter. After all, paper targets feel no pain. And if you drop a point or two, you learn. But shooting live targets, i.e., varmints, etc., always best to have the best possible load.

Finally - 125 gr. bullets. The very first loads I ever made in .30-06 used 130 gr. JHP's made locally in New Orleans, LA by a man who had a little shop in his garage. Those things were poison on the range and in the woods/fields. Shot them in a 03-A3 w/ standard iron sights. Rounds were a bit high at 100 and still a bit high at 200 but, right about 300 yds. those things would hit a gallon milk jug with absolute regularity. Extremely effective on feral dogs. Never needed to fire a second shot. Would imagine that you will find your 125 gr. load to be just as useful. Sincerely. bruce.

My guess, too, but it's nice to know for sure.

You have motivated me to drag out my HB .308 and shoot some groups. My range is closed for MX, but when it opens I will do so.

- As long as the weight balance is behind the left hand in Prone.

- If the 125 doesn't open, Speer's 130gr HP is a gawker that probably will and is a good precision substitute at 2.650"

And I did so.........

My two HB .308s, a Ruger and a Winchester, were not shooting up to par. Even with good sight pictures and good calls, groups were meh. Ammo was XM118LR.

Got to reload some better ammo. Stand by.
