Finally got to the range for the maiden voyage with my Krieghoff 470 Nitro. I've had some loads ready to go for a while, but our range has been closed for a couple months undergoing a major face lift. Construction finally completed, it reopened a couple days ago.

Anyway, I had five loads to try out. I loaded four each of five different charges of 5744 with my cast bullets. They were just air cooled wheelweights from my custom mold I designed and had Mountain Molds cut. The bullet is 500 gr. gas check design with a 70% meplat.

It was interesting to watch the regulation come together as the velocity increased. Some other guys had reported their doubles regulated well with 45.0 gr. of 5744, but that seems to be a very mild load and I wanted something more mid range, so I started at 48.0 gr. From my results, I don't think my rifle would like 45 grains anyway. As you can see, the lighter loads actually had the barrels crossing.

I shot two from each barrel at each target off the bench at 50 yards. The sweet spot was found with load #3. Two shots from each barrel measuring just 1 5/8"

Load #1) 48.0 gr. @ 1500 fps
Load #2) 51.0 gr. @ 1610 fps
Load #3) 54.0 gr. @ 1751 fps
Load #4) 57.0 gr. @ 1849 fps
Load #5) 60.0 gr. @ 1960 fps












After I reached the 57.0 grain load I think the pressure may have been starting to break down my alloy, because the regulation still looked pretty good. Accuracy from each barrel just began to open up. I'm going to try those last two loads with a Lyman #2 alloy and see if they tighten up any. Although I'm tickled to death with the #3 load, I'm somewhat surprised it was that easy to stumble on a good reduced load. I say reduced, but that dude has about all the recoil I would want for punching paper. Should make a dandy whitetail load too. Don't laugh, bambi's in deep trouble this year.

After I got home I inspected the bore. Not a trace of leading, just some light streaking that a couple wet patches took right out.

Overall a very good trip to the range. I guess the next project with be to come up with a full power load (2150-2200 fps) using RL-15 and my cast bullets with a harder alloy.

Looks like afun day at the range enjoy it.

Shoots pretty darn good, even if you were getting punchy after twenty rounds!

My the rifle serve you and yours very well!!!

looks like you have a keeper!!!! With a DR, just remember to hold it the same way each time you fire it. When I shoot off sticks, I rest me hand on the sticks and the DR in my hand

I LOVE MY FIREARMS AND SHOOTING, THAT IS WHY I AM URGING EVERY ONE TO GET THEMSELVES, FAMILY AND FRIENDS TO VOTING BOOTS !!!!!!!!!!!!!!!!!!!!!
