Yes I can calculate for different velocities at different temps, but I am a rookie at this long range hunting and my target (whitetail) don't give me much time to do many extra steps before taking a shot.

There is a powder chamber that is larger than the bore. I have some h1000 on order. It tested about the same pressure as retumbo with a little higher velocity.

I'm using retumbo in a high performance .416 muzzleloader. Pushing a 375g cutting edge copper @ 2805 fps at 25f and 2745 fps at 70f. The hotter the slower. Colder faster. I'm getting great accuracy just don't like the velocity change with temp.

I have the burn rate charts. I was wanting to know if anybody knew of a more temp stable powder

I have been using Retumbo with some pretty good accuracy, but I found it is inverse temperature sensitive. Velocity goes down as the temp goes up. Any suggestions?

Here is a little more work I did with the new Swinglock at 840 yards. The muzzle brake really works. 7800 foot pounds of muzzle energy and it recoils less than half of my savage 10 ml2's

I have a Swinglock custom muzzleloader. It is in .416 cal. It launches a 375 gr bullet over 3000 fps with very manageable recoil. Very long range muzzle stuffin toy. This is a video of my very first shot from the rifle. The muzzle brake and the bumb buster recoil pad really do their...

I would like your thoughts on what is the best .416 bullet for really long range shooting/hunting (1000 yards and beyond) The gun is actually a muzzleloader being built by swing lock custom muzzleloaders http://swinglock.net/416lrt.php It can push the rocky men 450g around 2700 - 2800 fps...
