Interesting shoot - thanks Sabotloader
Rifle Used: .50 caliber Knight Disc Rifle
Powder Used: Triple Se7en 2f
68 grains weighed per charge
Primers: Remington Kleenbore Primers
orange disc
Distance: 30 yards
Sighting: Open sights - fiber optics
Swabbed between every shot
Projectiles: .45 caliber .458 -
350 grain Semi Pointed Lead Nose
.458 sabot suspected of being a Knight
.45 caliber .458 -
350 grain round nose lead projectile
.458 Orange Knight Sabot
Sabotloader will need to help me explain the projectiles because I lost my notes on the projectiles and the sabots. All I know from putting them on the scale was that they weighed 350 grains.
The powder used was Triple Se7en. I first measured out ten separate loads. I used my volume powder measure and got readings from as high as 70 grains to 66.8 grains. The average was 68.0 grains. I then re weighed the charges making them all 68 grains. I funnel poured them into the rifle.
My first group of six shots
I fired the 350 grain semi pointed projectiles first. The #1 hit on a clean oil free barrel out of the Knight Disc rifle, Iwas more then pleased with the shot. I then swabbed (identical as possible between shots) and fired shots #2 through #5. Again I was not unhappy with the results. For shot #6, I adjusted my POI going to a full cover hold instead of the open six o'clock hold and was not surprised where it hit.
My second projectile used
These .458 diameter .45 caliber round nose projectiles with the same powder charge shot very well. As you will note on the target I had two flyer's. As many of you can relate, when I loaded those two shots that turned out to be flyer's, they were #3 & #5 I knew when I was loading them they did not load like the other four bullets. These were very hard to get down the bore, unlike the other bullets. As far as the grouping of the other four shots, I was very pleased with that.
Sabotloader can tell you the make and style of bullet better since he was kind enough to mail them to me for my testing. I had it written down, but like all things, lost it. [&o] Over all. I like the way the round nose projectiles loaded and the way they grouped with the open sights.

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.

Yes I'd have to agree with sabotloader the top
group definately has promise. Looks like you had
some fun shooting, wish the weather would let up
on us. Snow today with a projected low of 15
tonight. Did I read correctly " 68" gr. powder charge?
Have you had an opportunity to use any of the
harvester crushrib sabots yet? I would be very
interested on how they would shoot for you.
Any way any time your shootin your havin fun.

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.

Another surprise I had was with the 100 grain by volume or 68 grain by weight charge and that big bullet, there was real good down range thump to them. They were hitting the steel back of the trap and really making a ringing sound...

Here is a target I shot last weekend. There was to much snow to get a 100 yard shot so I settled for an 85 yard. This test was to test an MMP sabot with a Harvester Crush Rib for my Austin and Halleck + I wanted to shoot a new bullet that I had just purchased. I had never shot it before.
Hope this might answer your question about the crush rib.

My error in reading your post, you said plainly in the body 68 by weight 100 by volume.
Last summer when I was shooting those things either RN or JFP at rocks in the rock pit they would really crush into the basalt. It got to the point where I was picking a chunk of pit run rock laying on the pit floor then shoot it to see if I could split them. I really like breaking things with bullets, punching paper all the time gets old.

I am not surprized at all I have been telling you folks for a year about the 265g Hornaday interlock spfp it is one of the most accurate bullets I have ever shot in my life. I just use the cheap T/C sabots with them and they work great. I think the lack of a hollow point makes these projectiles more accurate.

Sabotloader I bought a bunch of those crushed rib sabots but have not really tried them yet. I guess I better get them out. I even got some of them in .430 and figured I'd try some of the Hornady XTP's in that size.
That is some good shooting, even at 85 yards. You would have no problem taking out anything you wanted to shoot at. Also on your other picture it gave me the fps of that big roundnose so I can run a few ballistics with it to see what I could expect.
I kind of like them...
