Ok first and second shot were behind the ribs on a hard quartering away shot bullets entered had approx eight inches of penetration then failed no bones hit. Bullets did not make it to the diaphragm. Pic one is this bullet. Pic two was a neck shot side of neck penetration was approx 6 inches then stopped. 250 berger OTM at 2915 FPS.
Solely knowing one bullet penetrated 8" and another penetrated 6 inches, along with the description of the impact locations = a clear failure for these bullets to perform on this bull moose. The performance of these two bullets qualifies them as candidates for 250gr coyote bullets.
Others may prefer to state these bullets performed up to expectations (design or otherwise) and/or the failure lies elsewhere. Simply a difference of interpretation and opinion.
Perhaps a bullet selection failure; ie the wrong bullet selection for the game. I'd have used a different bullet myself for moose and have stated so any number of times on this Forum. This doesn't change the fact that these two bullets reportedly failed to penetrate more than 8" on this moose.
Perhaps bullet placement failure. I'd have waited for a broadside shot to the ribs if at all possible to maximize the potential for taking out both lungs. And secondly, to avoid a lot of bullet caused blood and gore damage to the meat. Regardless, the bullets still reportedly penetrated less than 8".
Perhaps the bullet struck at an excessively high speed - beyond its designed impact velocity. Could have loaded the ammo down to a slower muzzle velocity because the bullets might not penetrate at normal cartridge MVs. Personally, I load them as fast as possible. Two 250 gr bullets penetrated less than 8" on hide, fat, muscle, guts.
Picked on too large a bull moose. Should pick on a yearling instead. But even yearlings are thicker than 8" across.
Three possible conclusions come to mind: 1) These 250gr bullets don't perform on moose. 2) These bullets aren't designed for use on moose, therefore if they don't perform, it's not their fault. 3) If the bullets fail to perform on moose, something else other than the bullet is responsible.
