41 Magnum Load Data Center
Posted: Mon Mar 06, 2017 9:49 pm
I'd like this thread to be a central repository here for all things 41 Mag/Spl
If you are already a FortyOner then you know the excellent characteristics of this great caliber. Reduced recoil as compared to the .429 magnum, outstanding inherent accuracy, conservation of powder as opposed to larger calibers with the same energy level, conservation of lead for casters of at least 10% using standard weight bullets, etc.
I have been a fan of the 41 since the early 80's when I carried a 5.5" Ruger Redhawk on duty as a deputy sheriff in a rural Texas county. Due to very hard times I had to sell off all my guns about 20 years ago and the last one I let go of was my Redhawk. Long story short when life got better a 41 Blackhawk was one of my first guns I picked up. I've been reloading for it again for the last few years and was blessed to receive a 5.5" Redhawk from my girlfriend as a birthday present last year, yes she is an awesome. Earlier this month I sold my 308 rifle to finance a Henry BBS in 41 of course.
Anyway enough rambling about me lets get down to business.
Here is a link to a spreadsheet of 41 loads that I have compiled from both reloading manuals an web sources. There are over 800 loads listed
https://drive.google.com/open?id=0B4yeP ... TVYa2pjWTA
The spreadsheet is usable on any of the free spreadsheet programs but if you have any problems with it PM me your email address and I'll send the file that way.
All the usual warnings apply to this data and I am not responsible for any damage to your firearm, yourself or others resulting from your use of the data.
As I haven't had a chance to take my BBS to the range yet I don't have a range report yet but I had loaded up dummy rounds to check function. My BH and RH love the 225-230gr Keith style from NOEs mold so I had several of them seated and crimped. The BBS needed me to work the lever with authority but did function okay. The Keith is a long bullet with an OAL of 1.700" to 1.710" and they were all sized to .412". I had to get a jewelers loop out to see what little damage functioning them did to the bullets. There was no damage to the driving band only a little on the meplat. Next I tried to function the BBS with a dummy round with a Ranch Dog 255gr bullet. As cast these actuall weigh out at an average of 263gr seated to 1.585 OAL. The Ranch Dog round would not fully chamber and I did not attempt to force it closed. Examining the round I can clearly see where it began to hit the rifling at 1.460". I dont know if this would still be an issue if the bullets were sized to .411" but will post here the results of any further testing with the Ranch Dog. When I measured the Farthest end of the forward driving band it measured 1.385". So this tells me that the rifling begins somewhere between 1.385" and 1.460".
I slugged the barrel of my BBS and measured it with a quality vernier micrometer and got .4096" and .4100". Right now all my lead is sized to .412" which I think will work well in all my 41s as my BH and RH both slugged out to .4095".
On a side note if you have a 41 wheel gun it is well worth the money to have the cylinder throats reamed to .4125". Both of my Rugers had chambers that the throat measured .409" which meant that the cylinder was undersizing the bullets before they ever got to the forcing cone. Having the cylinder throats reamed shrank my groups from 6"+ at 15 yards to one ragged hole at 15 yards with my pet load of 8.0gr Unique under any 215-230gr cast bullet.
I will post any further findings here and strongly encourage you to share your stories, information and data. Sadly I do not have a chronograph so if you do please share any results you have.
