With scope unloaded it weighs 12 lbs. My handload is either a Swift 570g A-Frame or 570g TSX at 2300 fps recoil is 88.12 ft lbs recoil velocity is 21.74 fps. Recoil is sporty but it's still fun to shoot. I have loaded the TSX up to 2510 fps but at that speed the fun index went to zero...
Is this a Ryan Breeding custom rifle? Is it built on a GMA Magnum Mauser Action? If so I'd have Ryan put a 24" 505 Gibbs barrel on it. Then you'd have something!
My .375 caliber 300g A-Frame that penetrated a 9' brown bear diagonally starting at the right shoulder still weighs 299.5 grains. Your friend got a 10 1/2 foot bear I'm jealous what a monster!
I don't know what type of single stage trigger Wayne put in my CZ550 but it's perfect. Breaks at a crisp 2 1/2 lbs Not for the uninitiated with my 500 Jeffery
Good luck! I'm sure it will come out great. CZ 550s are great rifles. Here's my CZ 550 in 500 Jeffery. Wayne at AHR did the upgrades (3 pos M70 type safety, straighten and fill bolt, and single stage match trigger). It came with the barrel band an NECG front sight. Kevin Weaver worked on...
44 Magnum is more effective for sure, but my Springfield V16 in 45 Super is easy to carry, shoot and a Buffalo Bore 255g hardcast at 1100 fps (from my 6" barrel) is nothing to sneeze at. I bought it from the Springfield Custom Shop a long time ago. I recently sent it back to have the front and...
My CZ 550 in 500 jeffery weighs 12 lbs with Talley steel QR rings and a Leupold 1.5-5x scope unloaded no sling. I wouldn't want it any lighter. It came from the CZ Custom Shop with 2 mercury recoil reducers in it.
We (my sons and I) have both M70s and a CZ 550. I think the M70 is preferable in 375 H&H being lighter and a slimmer stock. I think the CZ 550 in 416 Rigby, 450 Rigby and 500 Jeffery is just right. The action is as solid as a bank vault. The action might need a bit of smoothing but a little...
Wouldn't it be great if they invested in new CNC machinery and put a CZ 550 in big bore calibers with the 3 pos M70 type safety and single stage match trigger Wayne put on for me at AHR. I think at $1500 they couldn't keep them on the shelves.
That's just because you're running the 500 jeffery at the original 1920 pressure levels. With a strong action and new brass you can easily attain 2500 fps with a 570g bullet with the 500 Jeffery.
If I was going for a caliber like a 458 Lott I would look for a good South Carolina Model 70 in 458 Win Mag used and have it rechambered. You don't need a massive action for that cartridge.
Here's a 300g A-Frame using 375 H&H Remington Premier Safari Grade Ammunition. I shot my brown bear at 13 yards through a bush. The bear was quartering towards me, we had startled each other. It entered just behind his right shoulder, the bullet was found in the hide of the opposite thigh...
CZ 550 in 500 Jeffery. AHR CZ#1 Upgrade (3 pos M70 type safety, single stage trigger, straighten and fill bolt), Kevin Weaver put on the ebony forend and grip cap and machined the magazine follower so it feeds and functions like a dream. My favorite rifle. I use it for everything.
I prefer A-Frames but on soft skinned game. Bears, feral hogs and elk the .509 caliber TSX's have performed well in my 500 Jeffery. I'm switching over to 570g A-Frames as long as they shoot as well as the TSXs I'm sure they will.
I’m very happy with my CZ550 in 500!Jeffrey. I bought it new from CZ Custom shop. I was lucky to have Wayne at AHR add his CZ upgrade #1 For $500. It’s a great rifle.
