Based on the 338 Lapua case with the case taper reduced and a 30 or 35 degree shoulder with a .500 case neck length. Or maybe a 470 Mbogo




Plan on using a CZ 550 in 416 Rigby that I have.
 
470 500 grain TSX, 350 Grain TSX and 270 grain 375

The Mbogo looks fun.

I always thought about the 470 Capstick. Is there a 470 based on the 505?
 
From Sir Ron
"
470 Mbogo.
Same case capacity as a 470 Nitro Express.
Use 470 NE load data for plinking loads,
or use the 470 Mbogo to test loads for 470 NE, saving wear and tear on the double rifle.

The 470 Mbogo at same pressure as the 460 Wby can make a 500-grainer go faster.
That 500-gr TSX for the .475-calibers can be sped along at 2700 to 2800 fps from a 470 Mbogo
versus the 460 Wby 500-grainer at 2600 to 2700 fps.
That .475-cal./500-grain TSX is a pretty bullet, much better proportioned than a .458-cal./500-grainer.
2500 fps is the happy MV with that bullet in a 470 Mbogo."

Jake, Sorry to bug you again. I was wondering if you could share a. couple actual pics of this crossbow with me?

Xpedition Archery USED Scrapeline390X Sniper Gray Crossbow XACW1001 - Light Wear - Needs Bolt/Arrow Guide Spring UA5689​

If it is in a decent shape, would you be willing to sell it for $100 shipped? IS it missing the retention spring that goes over the bolt?
Thank you Ferenc

Good morning John, I just read your setup procedure for the northstar duplicator ator. I found it very hand and I did learn some things. I have the same machine and I am having a problem i can not figure out and was hoping you could shed some light on the subject.
