RE: One Target With .40/200 grain Lehighs
TNHagies,
That's a very good question. There have been other animals shot with these 250grn bullets out of a Muzzleloader. I would bet they were at a much lower velocity then i was shooting. I will get that information asap.
In my opinion they will perform the same at standard Inline velocities. 1600fps and up i see no problem at all. That's just an opinion and i will find out what loads Dave's (Lehigh)nephew shot his Deer with and the results.

RE: One Target With .40/200 grain Lehighs
My next try with the .40/200 grain Lehighs will be out of the Renegade's .45 caliber GM LRH barrel. It has a 1:30 twist and gives me two-inch 100 yard groups with .40/200 grain XTPs over 80 grains T7 FFG. Velocity with that load is 1760 fps. I can get the XTP up to 1930 fps with 95 grains T7 FFG, but the groups open up to four and a half inches. So it will be interesting to see how tight a group I can get with the Lehighs with 80, 90 and 100 grains of T7 out of that barrel. Then the question remains - will they perform as designed at velocities as low as 1760 fps?

The 200grn Lehigh bullet wont stabilize going that slow in a 1/30 twist.
I know "physics is physics", but guns and women are strange things and you never know `til you try.

I ordered some Lehigh bullets today, if I get every thing to gather I will be doing some calling and getting a pig hunt together. Just for fun between friends I will try and match your best group that has been posted with both the 250 and the 200gr bullets I willtry with the new Endeavor but if I am getting beat up I might switch to the Triumph. Let me know the measurement center to center of your best groups so I know what I am trying for. Lee

I'll definitely post target pictures and group size Lee, but I probably won't get to the range again for another two weeks.

sabotloader, Grouse I think we all agree you need to push them hard out of a 1/28 or you can slow them down in a 1/24, my thoughts are how does the bullet perform on actualgame. I think we've figured out how to make them shoot accuratly. I'm wondering what the limits of brass are. We all know you can't push lead too hard and there's ranges that XTPs and others perform best at. I am humble enough to admit I have no idea what the limits areof brass, that's why I'm asking. I'm just wondering if those who choose not to shoot 2300+ will be able to see the same (or similar) results. At this point it appears they make an excellent wound channel and keep driving. But if you knock 600fps off of them, how do you think will they perform?

The optimum velocity for the bullets terminal performance is anything exceeding 1300fps. Below this velocity, the bullet performs more like a conventional, jacketed mushrooming bullet with the petals only opening to about a 45 degree angle. Many jacketed bullet designs do not have any expansion at all at this velocity. The other advantage of the Lehigh bullet at a low velocity is the large metplat (flat nose) and open hollowpoint cavity which does impart a tremendous amount of energy to the animal.

[/align]In short, speed kills and we should attempt to hunt at a velocity that is the maximum level we can shoot accurately. We all know that recoil is a rather insignificant event in the field so we need to condition ourselves to this event while bench shooting. For recoil sensitive shooters on deer-size game, the new, 185gr bullet at a high velocity would be a better choice than the 275gr at a low velocity at the point where both loads produced the same recoil.
