I'm booked to Mozambique this September for Buff, Sable, Eland and Chobe Bushbuck(2).

My Chapuis 450-400 is acting up. It "lost it's regulation a year ago and was re regulated. All with the same lot of Hornady DGX. It has seemed to have lost it's regulation again. JJ at Champlin is great to work with and he's standing behind his guaranty and he thinks it may be ammo related, the Hornady loads are not supper consistent and he's found them to be a touch hot.

The recommendation is to try Woodleigh .410 400gr and RL15 at 66-67 grains. If the barrels group consistently he will re regulate to the new Hand load. Make a sense to me.

If I can't get the rifle up to,snuff in time .... Am I ok with a 9.3x74r SxS and a 375H&H bolt gun?
