For the last few months, I've been testing many different loads for my 89 in 577 that require fillers...including R15, N140, and Varget. While I got respectable regulation with many of them, I decided to continue testing some that fill the case and do not require a filler. I tried 144 grains of H4831sc and both impacts were perfectly horizontal and only about 2" apart. Then I tried 145 grains and got what looks to be my go-to full power load using Woodleigh 750 grain weldcores, average velocity was 2042 fps, this group (circled) was shot off sticks at 35 yards:

To top off a great Labor Day weekend, I seemed to have found a great practice load as well, this one is 75 grains of IMR-4198 with open cell foam taking up the space and an accurate molds 590 grain cast bullet, average velocity was 1761 fps, also shot from sticks at 35 yards:

After I finished up with the Heym 577, I took my new (to me) Browning B-S/S out for a round of clays. I found a partial box of Federal 1oz foster slugs at the bottom of my large box of reloaded target shells, and decided to give them a go out of the Browning at 25 yards, just to see if they would even be close. The following picture surprised me, pretty good regulation for a shotgun choked mod and full if you ask me! These two shots were taken offhand at 25 yards, the other holes are where the wads impacted:

Nice work & great shooting !

I think you should have included a few photos of the rifle & the loads for us Gun Porn guys ?

Hey @frog stealer what primers did you use for the 577 NE loads?

Had an excellent classifieds transaction with JoninCO. A truly honest and standup member. I wouldn't hesitate at all to deal with him again. Thanks, J!

Hi Lance, Hope you well. I collect Mauser rifles and they are very much part of my cultural history in Africa. Would you consider selling the rifle now a year on ? I'd like to place it in my collection of Mauser rifles. Many thx

I saw where you hunted elephant with backcountry safaris in Zimbabwe.
Was looking to book an elephant hunt and wanted to know how your hunt went
and if you would recommend them.

Thanks
Mike
hi, do you know about lions hunters, leopard hunters, and crocodiles hunters of years 1930s-1950s
I'm new to Africa Hunting. I would like to purchase a Heym 450-400 double rifle. I'm left-handed but would prefer a non-canted gun. Is anyone in the community considering parting with theirs?
