Next year's hunting season plan will be Antelope Fest in both Wyoming and Montana. Antelope is my all-time favorite tasty critter. just barely beating out Elk.

Going to change things up a bit this time by hunting with a mono bullet for the first time - the GMX. My son will use the factory Superformance 120 gr. GMX ammo in the .26 CM since the barrel likes it so much (it happens to hate the Outfitter version btw).

I'm going to however handload the 90 gr. version for my custom .25 Roberts. That barrel has always produced best groups with all my other loads at max velocity.

But, with a mono bullet and specifically the GMX, are there different rules-of-thumb for MV and groups? Does the GMX perform best with full-tilt loads or with loads dialed back some?

Thanks,
Pud

It's you and the bullet, and all the rest is secondary.
