I picked up these bullets this weekend, and just tried to check the distance to the rifling. There is a cannelure on the bullet, and the rifling pushed to bullet into the case leaving nearly a quarter inch between the case mouth and the cannelure. Is this kind of jump to be expected with this type of bullet? Since it's not a round nose, I was expecting a longer jump, but wow.

If I read you right, you're saying the bullet, when seated to the cannelure, will travel 1/4 inch before it engages the lands.

If so load a few this way and see how they shoot.

Weatherbys travel more than that and shoot usually quite well.

The idea that bullets must be seated close to the lands to be accurate is merely overworked.

No matter the jump it still has to fit the magazine- unless you have Ruger #1 or maybe an Encore.

Mag length just about splits the difference, perhaps an eighth jump. I just didn't know if such a long jump was normal. I'll try all three and see what happens, cannelure, mag length, and just off the lands.

Yea, I think that kind of jump is within normal limits. Those bullets shoot pretty well for me by the way.

When I tried those bullets in my 375 H&H I simply seated them so that the case mouth was at the cannelure. I shot them over IMR 4350 and was rewarded with one inch groups. They do not seem to mind a little jump.

A little off topic, but what is the advantage of a boat tail on a 375 bullet?

Same as on any caliber.....better trajectory at longer ranges. Believe it or not the .375 H&H can be a very long range cartridge. I once killed an eight point buck at well over 400 yards with one!

BC is .460, best I've found in a .375.

edit: and as much energy at 250 yards as a 30-06 at the muzzle

I have fired these 300 grain Hornady boattails in my .375 H&H and found them accurate. I use Remington brass, a Remington magnum primer, 67 grains of IMR 4064, and crimp it all with a Lee Factory Crimp die. I would take these to Alaska or Africa for use on thin skinned game without hesitation.
