Being a notorious "recoil junkie", I chime in on this subject...
S.Sumner, it may be true for some, but between both of my 500 MAG's I have well over 2000 rounds fired.
First, I don't think that he was intending to single out certain posters but making a general state like "when recoil goes up, accuracy goes down".
And Yes, as a general rule, when recoil goes up, be it rifle or handgun, the shooter's ability to shoot the weapon accurately goes down and in many cases exponentially.
When speaking in generalities, there will always be exceptions to that general rule. I have zero doubt in my mind that you are extremely proficient with your 500 Mag but that really isn't the issue. You are the exception to the rule and not really the focus of the statement.
My accuracy is just as good with my 500 MAG's as it was shooting in my Redhawk 44 MAG. These big guns are not for everyone. Some of us are recoil junkies.
Is your accuracy with your 500 Mag as good as your accuracy with lets say a vintage Colt Officer's Target 22 lr?
I can honestly say that I have seen experienced shooters jerk a 22lr around after just 6 shots from a 44 mag.
I can honestly say that I have seen guys that will bounce a tennis ball down the range w/ a 1911 completely miss an 8" target at 25 yards on his second shot from a shorty 475 Linebaugh.
Honestly, I think the 44 Mag is too much recoil for alot of shooters with the standard 240 grain load. Forget about it with a normal 300gr load, they are way more than most shooters can handle . If that doesn't get them, I have a great 340gr LBT LFN @ 1490fps 44 mag load for my Redhawk that will be too much for most of the guys that handled the 300 grainers.
Heck, we have people on this very message board that think the S&W 329PD is one of the most violent handguns that they have ever shot. Frankly, I'd tend to believe them.
Anyway, I just think that the extremely experienced handgun hunter, like I assume that you are, tends to forget that the average handgunner neither has a regimne to check for recoil related bad habits or shoots enough to total put recoil out of their mind.
Remember RedHawk, we are the exceptions...
