My memorysays:
6 MMP HPH-.458 Orange sabots - the machine was purchased from Knight
6 Speer 350 grain .458 JFP - jacketed flatpoints
6 Hornady 350 grain .458 RN
That group into the upper target looks really promising and the same for 2-5 in the bottom. When I shot them, I was using a hoter load (100 grains t7-2f) and getting pretty decent groups also. This is the first target I shot when I was testing the .458's

Did you notice any physical difference between the knigh .458 sabots and the MMP sabots? Did one load harder than the other? I wan on the Knight web site the other night and could not find that Knight was offering the .458 sabot any longer.
The main reason I sent the projectiles to cayugad is the he is a more rounded tester than I am. He will shoot any projectile for testing purposes, and I guess I will too, but I am really only interested in flat-quick bullets at this time, although If I were hunting hogs these loopers work get under 100 yards. And they carry a lot of energy with them.
The orange Knight Sabots I have seemed to load as easy as the MMP sabots you sent me. All but the two flyer's. I really had to lean on the range rod to get them down to the powder charge. Even though I had swabbed the barrel between every shot.
As for the powder charge, it was the same you were shooting. I took my volume powder measure and set it at 100 grains. I then poured out 10 charges. I weighed each of those charges. I added all the numbers together which came to 680.00 and divided by 10 to get the 68 grain average. I then went back and re-measured and adjusted all the loads to equal 68 grains. The charges varied between 70.0 and 66.8 grains from the volume powder measure.
I will be getting some of those 350 grain Hornady Roundnose .458 projectiles. I like big bullets since all my shots are close normally. This allows me to really put a hurt on anything I want to shoot.
They did shoot well for you. I think those big 350 grain might make a good hog load or for black bear around here.... thanks again.
