Thanks fellas.
LaOtto, you may be right about my questions being too open ended, but hence to cause for "discussion!"
I agree with the philosophy behind your answers and you're correct about bbl lengths for the two rimfires. I'm a big believer in the .22LR and while not even a dabbler in the .17 Hummer, have studied it to better know the .22 WMR.
However
optimum bbl length for the .357 Maxie I would think would woul be no longer than 22 inches (and probably less) because it is a straight-walled case with an ample expansion ratio. I have always thought optimum bble length for the .357 Maximum would be between 18 to 22 inches and probably closer to 19-21 inches. My whole goal is to determine the (somewhat) perfekt length
but no more!I run into shooters and their opinions who seem enamoured with 16 inch tubes in a whole range of catridges and their uses, but my questions about the .357 Maximum were to try and learn from others' experiences where they found the "balance" between
'not too much of this to too little of that'. For myself I've decided anything shorter than 20 inches or even 21 or 22 inches in the .223R, .222 and .221 Fireball (in a rifle) and I'm sacrificing performance. Funny you would mention the Fireball as it is on my list of Encore barrels to get, if not rebarrel my .223 to that round.
Plus I like those evil black rifles Jim Zumbo disparaged. Most times I wouldn't want an AR with a barrel less than 20 inches which is the length that round was designed around!
But a straight-walled case like the .357 Maximum ..... I'm thinking I will try to draw "data" from what seems to work well with the .45 Colt, .45/70 and other rounds similar to them - without sacrificing performance and creating excessive muzzle blast (if I chopped a barrel that short!!). Of course there's the whole issue of trying and selecting the correct gun powders too! Which may prove to be the biggest factor in this whole deal.
A general rule of mine I tend to like shorter (vs longer) barrels for shotguns for field use (not the trap range, but the
bird "range"). Howqever I'm just the opposite when I select the "optimum rifle package."
I like longer rifle barrels - usually. But in a .357 Maximum I would limit bbl length to 22 inches if not chop it down to 21 or 20 no less than 19 - 18 1/2 inches. The purposes I'd shoot .357 Maxie's include from a tree stand for deer (at normal ranges 50 to 150 yards), or as a truck gun or 'back up' to a .357 Magnum revolver (a camp gun or hiking gun). I know the .357 Maximum excels best when staying with that ammo and cartridge, but it is versatile and safe enough to allow shooting 'Magnums' and .38 Specials
althogh accuracy would like suffer substantially.
Before leaving the idea for the "ideal .357 Maxie barrel" I realize some folks will want to shoot that round in a rifle in the smallest, most compact package they can! Which would require chopping a barrel to as close to 16 inches as they can and still be 'legal.'
For a survival, or truck, or back-packing gun those would each have their place. And personal preferences are VERY FUNNY THINGS!
Range performance -- The idea to compare bullet perfomance to remaining foot-pounds of killing energy is probably the most-measureable method folks could agree on. Before you mentioned the '1000-fpe convention' when deeming what's an ethical deer-killing round, I had forgottern about that convention - altho I have used it before! (when using .223Rem reloads to bag my deer).
To wrap this up I will probably settle on 20 inches if I chop my Handi barrel, selecting to reload with the slowest powder I can that will be that perfekt balance between powder volume versus velocity when shooting 180 - 200 - 220 grain bullets.
Also there is a small following of the .357 Maximum who shoot it in Contenders or Encores, and if shooting a HR didn't quite satisfy an itch, I could always settle on 21 or 19 inches if 20 inches wasn't close to "perfekt."
But thanks for your comments and inputs!
