Do you have load development for 450 Dakota to share? 500 Grain Bullets? Swift A-Frame, Swift Break-Away Solids, Barnes TSX.
What distance did you zero to?
Off bench or sticks?

Bullets?
Powder?
Primer?
Results
-FPS?
-Accuracy at 100 Yards

Thank you!
 
Ok. Did it the hard Way.

450 Dakota - New Brass
500 Grain Swift A-Frames.
H4350 - 100 Grains.
Federal GM215M
COAL - 3.701
2296 FPS

50 Yard First. To validate new scope.

Finished with 100 Yard Zero. Same results.

Last night I loaded 10 rounds of 500 Grain Swift Break-Aways with same recipe.

I’ll shoot those next Saturday to confirm results. My shoulders need a rest.

I shot from a bench using a rifle rest that was very stable and has padded V rests and adjustable elevation at both ends. Open butt so I could get a firm rest on my shoulder. Only downside was having to shoot from a sitting bench. Little sore today…

I also had several boxes of various loaded ammunition to include custom loaded of Woodleigh, Barnes, Cutting Edge, Swift that came with the rifle and some I picked up that was loaded by one of our members. I shot from 4 boxes ranging from 400 grains to 550 grains. I shot 2 rounds from 4 different boxes and recorded velocity and results at 50 yards. All grouped well at 50 yards with speed from 2283 to 2474 FPS. I still have 6 boxes to test. Unfortunately, I have no load data from those boxes.
 
That's a lot of options and I can definitely see the need to give your shoulder a break. That's the great thing about the 458, there's a huge range of options on bullets depending on preference and intended game. You have the ability to make a great one gun safari rifle if you choose to do so. Keep us posted on your results.

Good Evening. I am very interested in you hunt for the spiral slam. March in 2028 would be fine for me

Couple of quick questions:

1) Can we add some additional species on
2) what do you want for a deposit?
3) how do you want me to sign up

I'm on whats app or email

I think forum prohibits making reference or giving personal references to PH/Outfitters that don't advertise on this forum.

But you can call me. I would be happy to discuss Cape Buffalo .
