243 and magnum primers

[carrollshooter]

Has anyone tried magnum primers with H4831 and 105-107 gr. bullets? What were the results compared to benchrest primers?

on longrangehunting.com the botw load is i believe h-1000 not sure of the primer. in their cold weather it would be a good idea. used it to kill an elk at 688 yards in vid. they use an 8 twist krieger barrel.

I observed better es & sd using magnum primers in the 243win when using extruded powders like IMR 4831, 4350, and 3031.

Is this a misprint or did you mean 688 yards with a 243? If this not a misprint this has to be some sort of record for an elk kill considering that it must have been well under a 1,000 ft - lbs in energy at that distance with a 243. Truly amazing!

That would be more of a miracle than amazing.

I would be the last person to say anything but how many animals get away wounded. My neighbor shot an elk that had a 25 caliber bullet imbedded in his neck. It also had one in it belly and the intestine was leaking fluid. My guess is one of these long range shooters.
