congrats, Cerdan, welcome to the club.
i've enjoyed Smith 29's over the years, the classic 6.5 inch dirty harry barrel length, has the most graceful lines for barrel length, imho
as you try, diff. models, i think you will find diff. recoil and handling, esp. between a blackhawk and a 29.
gentleman's rule, don't blast away indoors with other shooters around, or even outdoors too close to other shooters you don't know, while we enjoy the blast, others can get bother and have their own shooting ruined.
with the 44, i shoot about half power loads with hard cast bullets, then do 2 or 3 speedloaders near the end, which helps clear the barrel a bit before taking home for scrubbing
for me, if i shoot up to the 45 auto, i hold my gun with the right arm fairly straight and tensioned up, then sight with my chin on the arm like a rifle extension, but for the 44, the upper arm and shoulder are bit relaxed, letting the gun recoil, but the moment the gun comes down on its own, then using the sights still in line with target, fire the next shot. (watch the dirty harry technique, it works well just like the movie)
the rest of the 44 mag club, what are your thoughts on how best to shoot this caliber? regards to all
