Home Forums Hunting & Shooting Express Rifles and Big Bores Only The great 458 Winchester. Everyone should own one at least once

Sir Bob's AA-5744 load was shot at 42 degrees F.
I shot basically same load at 67 degrees F, also in a Ruger No. 1.
Our results in past have been in good agreement, uniformly.
His Magna-ported barrel only loses a few fps versus my non-ported barrel of same Ruger make and length.
He got 2610 fps and I got 2725 fps with same charge of 65 grains AA-5744 under the 250-gr Monoflex.
This suggests that AA-5744 might be pretty temperature sensitive.
We both got good accuracy with that load.

Converting 0.45" for three shots at 50 yards to MOA:

0.45" X 2 X (1 MOA/1.047"@100yards) = 0.86 MOA

I used a higher powered scope (9X) and got 0.63 MOA.

The load is a good one for large varmints and deer, speaking of which, the view from my tripod yesterday, right before sundown:



After a while, I whistled at that deer a few times, then barked like a dog (Hillary Clinton campaign like), then tried to cackle like Kamikaze Harris.
Nothing happened except the deer looked around curiously.
Then I tried some blowing and snorting sounds and it ambled off, nose to ground.
That is a half-mile long cornfield recently harvested, with lots of broken up cob corn on the ground.

Walking out, I saw the moon is a waxing crescent, it will be gibbous next weekend, and I will be giddy.
