Hi guys, just wanted to bring up loading the 500 S&W. I recently purchased a 500 S&W BFR revolver and looked here and elsewhere for midrange loads. I didn't find nearly as much info as I do for more common calibers so thought I would share my experience for others who may find themselves in my situation. I knew I wanted a 50 Cal but also knew I didn't need all the 500 S&W had to offer with its huge case and high 60k max psi. I was actually looking for a 500 JRH but the lack of brass and reloading info was a problem.
So I bought a used 500 S&W BFR for $735 and went about looking for less than full power data. Problem was the most common data for that was using Unique or Tightgroup powder which barely puts any mass in the case which has the possibility of double or even triple charges going unnoticed.
I ended up using starting data for IMR 4227 and found that it filled the case nicely, did well with putting plenty of power downrange, but still had very manageable recoil. In fact I was able to fire it one handed. After hearing about how vicious the recoil would be I was actually nervous to pull the trigger. I found out due to the fairly heavy mass of the revolver coupled with the fact that the pressure was only around 44 Mag levels that it was actually very enjoyable to shoot.
For load info I am using Lyman data. Cross checked with Hodgdon's data.
350 gr Berry's plated using 37.1 gr IMR 4227 (they start at 37.3, but my powder throw settled on 37.1 so I just went with that) with an overall length of 1.985
They claim it's in the 1500 fps range which is plenty enough for me. I didn't check it over my chrono but plan to at my next range session. Accuracy was good as I was hitting very close to point of aim and forming nice small groups. My next outing I plan to bring the chrono and a tape measure. This first outing was very informal and just to see if I even liked the gun and ammo. Turns out I loved it and am very much looking forward to getting it out there again.
For the next outing I have more of the same load plus a load of 40gr H-110 under the same 350gr Berry bullet at the same 1.985 oal. So more to follow and just want to let other new to 500 S&W guys out there know it's a fun gun to shoot.
