03cobra456 , I use shooter Choice solvent and hoppe #9 on my S&W 500 Mag. I use brass brushes in the bore and cylinders. I use a stainless brush inside the area where the gap is by the forcing cone and top strap. If you have a stainless gun, use the lead free cloth to remove the black stains on the cylinder, it works great, but don't use the lead free cloth on a blued surface.
I have a 4 inch 500 Mag and a 6 inch 500 Mag. I sold 2 of my 8 3/8 inch and my 10 inch PC model. I like the shorter 500 Mags.
If you want to talk recoil, the 700 gr. at 1250 fps and no compensator will get your attention quick. I have a custom end cap that was made for my 4 inch 500 Mag, so there is no compensator. WOW what a handful. I have shot the gun one handed for practice. Just in case I ever have to use it in an emergence situation. Yes 2 hands are better. To tight of a grip will result in a double fire, where the trigger gets pulled 2 times. So do not over grip your 500 mags.
I have owned a 500 Mag since 2003 when they first came out. My first 500 mag was a BFR in 500 Mag. Magnum Research actually beat S&W out on the market with there own gun. Magnum Research already had the platform and just needed all the spec's to make the larger bore barrels and chamber the cylinders.
I had an order in for a S&W 500 mag, and the gun shop called me as ask if I wanted a BFR instead of the S&W, because the S&W 500 Mag was delayed, due to some problems. So I went ahead and took the BFR and kept my order in for the S&W 500 Mag. About 2 months later I got the S&W. It was fun having both guns to do a side by side comparison.
All I can say is, I love them both. My BFR has taken quit a few deer, bear and hogs. My S&W 500 Mag has taken a few deer and a black bear.
