pop;

Just bring the .416 but before you go, twist a wrench socket on the bullets of some loaded rounds of Horny softs to score a round line about 1/4 inch off the bullet tip, then grind to the scoring line on a wheel, load them single into the rifle and check zero.

There, solved.

Bring ten or so with you. When you are in your blind load one up the spot and keep the rest of the rounds in the mag as-normal.

You can test the efficacy of this modified bullet if you like, or rely on it w/o. It should be a real bomb on leopard.

One gun safari, all you need.

If I had a .416 I'd do it for nothing and make some comparisons. A Hornady so-modified should open fast.
