Omega-Lehigh's @ the Farm
#1
Decided that i wanted to get out and do some shooting today so I grabbed the Omega and headed to the farm.
Those that have read the information on other sites already know about the .400/200 Lehigh being to long for the 1/28 twist, unless you shoot them @ 2300 fps. I shot them from my 50 cal U-Mag @ about 2000 fps with a 1/24 twist and they really performed well - got some outstanding groups @ 100 yards.
I then shot them from my Triumph with a 110 grains of T7-2f and could not get a group tighter than 2 1/8" group @ 100 yards. When Dave, Lehigh Dave, ran the numbers they computed out to need a velocity of 2300 from 1/28 twist.
Thought I would try again today with a different rifle and 120 grains of T7-2f. You can see i was getting around 2100 fps and the group showed some promise, especially if you factored in the "wind" at the farm. I estimated 5-10 on the average but there really was some decent gusts also.
Next, I decided to shoot the .452/250 grain Lehigh. Remembering that this is only a 75 yard target, but those 250's shot awesome again considering the wind... #8 is 'Semisane' shot - one of his rules applys here. It truly was 'operator error'
The final experiment of the day was to shoot at a clump of new spring wheat that lasered 201 yards. The field was fairly dry so seeing the dust from the hit was not a problem. The calculated BC is .147, but for .147 bullet it outshoots my .200 Nosler.
I normally shoot a .451/260 Nosler partiton in this gun. It is sighted in for that bullet and I have shot it quite a bit at all ranges to 200. I KNOW - that I have to hold on the second cross hair to get the Nosler on target at 200 yards. Well, my first shot with the Lehigh, I did exactly that - held on the second ballistic line and took the shot - the bullet was a little high! and left... That really surprised me I really felt it would be low. Loaded up again this time I held directly on the clump and shot. Elevation was RIGHT on but still a few inces left. Third shot I held on and on the right edge of the clump - results - right elevation and right on the left edge of the clump of wheat.... The point all three shots would have been kill shots on a whitetail. The bullet is real! and the BC is low.
Here is today's target shot @ the Dinger Farm...

This is the Target from my U-Mag shot a couple of weeks ago..

Great shooting and a good report Sabotloader. Those are some impressive velocities you're getting with the Omega. I can't quite get there with the short barrel X7.
You can't blame me for #8. I just checked the post on The Ten Gods Of Muzzleloading (http://www.huntingnet.com/forum/tm.aspx?m=2933626) and it seems like we missed one -Dangdaflyer.

That's some very fine shooting and a nice detailed report. I know Dave appreciates all the extra effort in trying these bullets. Wait till you see how they perform on game. The other bullet companies have nothing even to compare to this bullet in performance on game.

The targets look OK on this report but they are not my most important issue here. One of the main reason I wanted to shoot the 200's is that I could shoot from 0 yards to 200 yards with the same sight picture, never being higher or lower than 3". Well today, with a bullet that has a supposidly low BC I did that exact thing. I would not hesitate a bit taking that 200 yard shot, well I should not say that -that flippitantly(sp if it is even a word) 200 yards is a long ways out there.
Although as I have aready stated - really makes you wonder about published BC's of other bullets.
I am excited about using either of these two bullets, the 200 or the 250, but at this time I really think it will be the 250.

On another forum I was asked about Harvester Short Black vs MMP HPH-24... I think I might like to add my repsonse over here also..
I have tried the Harvester sabots. and like yours mine is an older Omega and does have a more open bore so I do not need the CRib sabot. I can load the regular MMP - Harv Short black or long Black - even the MMP Orange .458/50 cal sabot.
I really do like the MMP better than the Harvester from the Omega. I can switch to the Harvester and see no difference in POI... It just seems to me that the 24 loads smoother all the way down the barrel.
The other thing if you look at a 250 grain Lehigh, it is longer than a typical 250 grain copper lead bullet - so I kinda like the bit if extra support + the extra length might grab more surface of the riflings and get better rotation. If you look at the body of the bullet you'll see that it has, what I call a longer barrel to the bullet - so putting it in the longer sabot might make it grip the bore better and the cannur rings in the bullet help it grip the sabot.
I see you're using MMP sabots for both the .40 and .45... How do these load in your Omega ? Have you tried the Harvesters ?
My Omega (older - 2005) really likes just about any .452 bullet in the Harvester short black with T7 or BH209.
