I used the same setup last June on a buff and plains game hunt, CZ 550 Safari, worked up loads using Hornady DGX and DGS to zero the rifle and practice, probably 75 rounds. Off the bench was a proper bitch with recoil until I got smarter and used the LeadSled. I switched to Swift A Frame and Swift Breakaway solids, both 400gr, for the hunt. I think that the muzzle velocity was in the neighborhood of 2350 fps. One thing became immediately apparent between the Hornady and Swift bullets, when loaded to the exact same cartridge length, when trying to put 4 cartridges in the magazine, the Hornadys would not feed up the ramp into the breech (both DGS and DGX) whereas the Swifts (A Frame and Breakaway Solids) fed without a hitch. I suspect it was to do with the profile of the bullets themselves. The Swifts were accurate enough for hunting and worked flawlessly, no pressure issues and when hunting the recoil was unnoticeable, offhand and on the sticks. Adrenalin works wonders. The load in grains for the Swifts was considerably less than the Hornadys but the point of impact was almost identical. I managed to get the Swift softs and solids to shoot to the identical spot and I was very impressed in their performance on the animals I harvested. Bill Hober, President of Swift bullets suggested to me at SCI that the load for the Breakaway solids should be 2 grains less than the A Frames to have the same point of impact, he was right on. I can get the load I used to you tomorrow when I get back to my gun room.
