450/400 3” Velocity…is it enough?

Folks it was brought to my attention by TroubleShooter (Great Catch bye the way) that the Data that I presented on my post #22 was in error ... The Data I copied was for the 450-400 3 1/4" page 159 of Wright's new book the Data that should have been copied was page 157 of his book for the 450-400 3"...
I apologize for my error and thank TroubleShooter for his Eagle Eyes
 
Not to rain on the parade but friends don’t let friends run Hornady bullets on DG. All PH’s I’ve ever asked say “NO” to Hornady bullets… YMMV but I had great luck with Cutting Edge softs and solids in the same caliber - other options like Barnes or Swift AFrames would also be much better bullet choices imho if you can get them to shoot. I’d try for a bit faster as well, in the 2050-2100 fps if you can - possibly can be accomplished by a slightly different powder, again assuming you can get it to shoot. Cartridge is by nature low pressure so you can go up a bit (Starting low of course). Also, the new Garmin device is an amazing tool for measuring velocity. In the end, if 1950 is the final speed that regulates and is accurate then you gotta run what you bring and get closer!

View attachment 713145Hi guys!

Looking for some opinions..

I’m in the process of developing a load to regulate in my new to me double rifle.
After trialing about 5 different gunpowders en 5 different bullets I finally found a combination that regulates well in the rifle.72 gr of IMR 4831. As I increase the velocity the group starts crossing.

The problem is the regulation velocity is only 1950 fps out of 24” barrels.

Is this enough for cape buffalo?

Please share your thoughts

Cheers

F
Plenty! .. have a blast.
 
It will work but I would try IMR 3031, that may get you to 2050fps

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.
