Got out today and once a week or so ago to do more testing of this new bullet from Lehigh. As stated the bullet is labeled .458 as it is truly built for 45-70 barrels that have been converted to a muzzleloading barrel. At .458 it is somewhat difficult to get through the crown of the regular 45 cal. muzzleloader, but once through the crown it loads very well. I have chosen to size the barbs on the bullets to .454 allowing it to pass through the crown of regular ML bore easier. I have really good luck shooting this bullet and really good groups! But, all my testing has been done with BH-209 powder. The test today was to see if I could get similar results using T7 powder, which I normally use. It is just so much less expensive to shoot. Plus in Idaho where I am required to use cap ignition during ML season, I was really interested if T7 would get the job done. Today proved T7 works just fine! but it needs to be noted the bullet needs to be loaded in a dry barrel! This picture shows the result of today's run to the Rock Pit. Back in March I did another test shoot trying to compute the BC of the bullet and completing a Ballistic Chart for the bullet. I will tell you the group shot could have been tighter and would have been tighter if I was not so concerned about shooting through two chronographs especially the one at 100 yards. It would be a real pain if I were to shoot one of the chronographs. I also developed a 'Bump Stick' to help me get the bullet through the crown and started down the bore. The rains came again this afternoon and cut the shoot short, but I got what I needed done - would have just liked to have shot a little more.

I believe the bullet is a very good all around bullet way more than you need for a antelope, deer class animal but will be very good for elk. Your NEF with the 45-70 barrel should be near perfect for the bullet as is - I don't think you will need any resizing. I have shot it to 170 yards and it got there just fine. Have not shot it to 200 yet. The CF style bullet from Lehigh works really well - this is one example I have handy

Really neat info. Have a lead on another Lb of 4759 so I'll consider using it under the bullets. Here in VA it's ML just have to be loaded through the muzzle and be 45 bore or more and 35 cal bullet or more. So mostly SML for me. Bet that 458 be a WHACKER in my Omega/Bestill 45 Brux. I'll get an order off and see how they do. As usual accuracy rules, of course safety 1st. 10
