Hi Folks!

I recently got a Big Boy in .44 mag and love it. I'd like to sight in for 100 yard zero, but don't have that kind of distance where I live. Has anyone chrono'd a 240 gr JHP or similar round for MV? With this info, I can input into Nikon zeroing program and calculate aim point at shorter distances for longer distance zero. Alternatively, actual experience with this round in a Big Boy would suffice.

Thanks for the help!

Welcome from CT, John. You're in good company here and I'm sure you'll be getting helpful replies to your question. Glad you joined the conversation.

I'm looking forward to hearing those numbers as well .... the numbers I've seen run in the 1745 fps

No numbers but I sight the 44mag two inches high at fifty yard and good to 150 yards. Done it that way about fifty years I guess. Dead on at 25yards shoud give you about two inches high at fifty.

This is my "go to" reloading site http://www.hodgdonreloading.com/data/pistol
W/10" barrel and Lil' Gun powder and 240g JHP max load shows 1582 fps. Obviously more w/rifle {I forget the formula]
H110 slightly lower

Add ABOUT 50' per 1' barrel length for MV. That would give you near 2000 fps. [not carved in stone !]

a 240 gr JHP out of a 44 Mag with a 2000 fps muzzle velocity would be one heck of a round .... out to something over 100 yard, I'd think it would have a relatively flat trajectory and deliver outstanding impact and penetration .... I'm more excited than ever about developing such a round our of ours
