Ruger guide gun (m77) with Hornady dgx and dgs 400 grains.
Gizmo,
From the get-go I will say that it appears to me, the Swift A-Frame is the very best premium soft point I have seen, in terms of consistency in performing as advertised.
They do not necessarily always regulate well in doubles though.
On the other hand, the DGX and DGS seem to have been designed with doubles in mind.
In my photos there is a picture of DGX bullets, two recovered from animals plus one in unfired condition.
There are some folks who say DGX bullets are not right but so far, my very limited / two animal experience seems to suggest such folks have been brain washed by glittering advertisements from companies like Barnes and are to be pitied, LOL.
I would however not use the DGX in any super velocity type cartridge (Weatherby and such).
When I shot the buffalo, fatally wounded, he dropped to the shot but got back up and ran.
So, I shot him again with a DGS from my other barrel.
Again, he dropped to the shot but this time stayed down.
This solid was not recovered unfortunately.
By my way of thinking, the DGX and DGS are the absolute perfect shape/profile bullet for hard hitting, yet not so "flat and square" as to make feeding in repeaters impossible.
I like the fact that the jackets are soft (malleable) steel, plated with gilding metal to go a bit easier on the rifling.
My prediction is that you will do well with them on your pending safari, I did.
Cheers,
Velo Dog.
