hoppes-no9,
Great minds think alike!
If that is the only goal (and one does not intend to take advantage of upward-pointing "jets") why not save some money and shoot lighter loads? Most people serious enough about their game to consider porting have access to light factory loads, or load their own.
Yep, too true, but as it happens, the "jet" porting fad occurred before the present lite and super-lite load fad.
Regardless, I still contend that unless you have blown off the masking tape in your hypothetical situation, you have not redirected ANY gasses, and therefore cannot have ANY effect on muzzle jump. How can this be otherwise?
Agreed. My point was that the pressure may no be sufficient to blow off the tape; but, with the tape gone it could contribute to the energy reduction. We don't know if
Bones placed a small bit of tape over the holes, or wrapped the barrel with few turns, ergo my concern over a lack of data and the subsequent tailpipe example.
Edit to add: IMO, of all the things that matter in competitive target shooting, porting (in an attempt to reduce recoil/muzzle jump) is very low on the list. Much more important are things like gun fit, technique, gun fit, mental preparation, gun fit, vision, and gun fit. In that order.
Correct, but after all that has been done, the comp shooter may be looking for additional ways to possibly improve his scores, no matter how low on the list. Years ago, I was sucked in and shelled out over over $100 for special shooting shoes.
Long after my
Shoot Boots were retired, three of us AA types were practicing skeet with a rookie shooting last. I happened to notice the three of us were wearing CostCo's inexpensive Court Classics and the newbie wore an expensive name-brand pair. The three of us came off station 8 clean. The rookie missed one or two targets and commented that he needed a lot more practice and wanted to know if there were any secrets. I pointed to his feet, and with a straight face commented, "You've got the wrong shoes." He looked at our matching CostCos and thought I was serious until the others started laughing.
