Well guys I have been away in the Kootenay's for a week and haven't been able to get on line much so wasn't able to answer this question for you until now...
I have 2 consecutive #ed stainless steel 5.5" barreled Ruger Bisley Vaquero's in 45 Colt that I load up to 345gr bullets into. My 330gr WLNGC's do 1280fps to 1300fps but I haven't had a chance to chrono the 345gr'ers yet so can't give a velocity.
These are extremely strong and accurate handguns... I can when I am doing everything right get all six rounds from both guns into an 8" X 11" target @ 100 yards with my 330gr loads.
When shooting these loads in a Vaquero the gun pounds into the web of your hand where as the Bisley grip allows the gun to roll more giving me the impression that the recoil is better/easier to handle.
This may not be the case though... With these heavy recoiling loads the Bisley grip actually snaps my wrist very hard compared to the Vaquero style grip.
If the loads are heavy the Bisley grip is far harder on your wrist and the Vaquero grip is way harder on your hand. In other words if you do not have strong wrists I couldn't really recommend getting a Bisley.
There are other advantages to the Bisley as well... The hammer is far easier to #### and I find the trigger far nicer as well.
Considering that the Bisley style handgun was designed for competition shooting it may also be a more accurate gun as well...
Anyway those are some of my thoughts...
