Re: Enduron powders
I did a quick temp test w/4451 in a 25-06. I loaded six rounds, 50.5grs, 100 Speer 20 off. I put there in the freezer overnight then the next afternoon put them in a small cooler w/ice pack. A the range I put the other three on the hot macadam walkway in the sun to cook.
I fired the cold ones first then the three now toasty ones immediately after. All six shots fired in under a minute.
The results 10' from the muzzle, 24" barrel
Avg - 3248.......3259.
ES - 16.2.......11.9
SD - 9.0 ........6.2
