Hunters / Rifle Enthusiasts,
HORNADY:
I took the Buffalo in my avatar with the Hornady 480 gr DGX and DGS, one from each barrel of my .450 No2 NE.
The recovered DGX is shown in my media photos.
It worked very well from the buff's point of view.
However ...... my regulating load (very accurate for a double) was only 2050 fps muzzle velocity, from 28" barrels.
The DGS was not recovered.
The DGX is jacketed in mild steel.
But sadly, the ogive jacket is formed much thinner than it is on the shank.
The steel needs to be same thickness all the way from the base of this bullet, to the excellent shaped flat tip.
Furthermore, the lead alloy core needs to be bonded to the steel jacket.
WOODLEIGH:
For double rifles, the Woodleigh bonded core bullet is usually preferable (surprisingly, Woodleighs were noticeably less accurate than Hornady, in my particular .450 double).
If one must use the DGX, as others here have already said, I caution you to keep the velocity down.
SWIFT:
In bolt action and single shot rifles for heavy game like Buffalo, from what I have learned by befriending PHs and fellow clients alike, is that the Swift A-Frame is the best of the best premium bonded soft nose bullet.
There are others that are about as good but none better, especially when one also considers how wide spread available the A-Frame is now.
Stay on that front sight!
