I can’t speak to “stable enough” in the way Randy did, but here is some real life experience for reference.
Had a 15-14 1/4 that shot real good. Not internet good, but won half the super shoot good. Feeling real ambitious went to shoot in low 30’s. Something was really wrong. 1” gun at 100 yards. Went to look at Bullet holes. Not round. Gun shot at 42 degrees. Bullets measured 864. Found some boat tails that were 850, maybe a little less. Shot a hole. Shot another hole. This was a wake up call for me on how close we are cutting it on twist rate. Randy May be correct, but I follow the herd w 13.5 and haven’t had problems.
For the real techies, I was about 850 feet elevation.
Here's THE deal, as Mark states, and observed, we know that marginal stability, "works", and may work very well in certain conditions (air density, as he observed in the colder environment can be a deal wrecker) . . .
if one has that "good/great" barrel - even most of the time.
As most do, one can purchase multiple marginal twist rate barrels looking and hoping for that "
hummer", which must test/defy the laws of physics! Or, from his favored barrel maker, purchase a barrel with a twist which produces Sg1.4+, and enjoy, "
one of the best barrels he's ever owned."
Of course, in the PPC world, employing a "faster" twist amounts to heresy, or, getting out of line and not going over the cliff . . . for the individual who can afford only a barrel, or, two per season, and insists on staying in line, the hummer quest can be epic - possibly one hummer every ten to twelve years - a LOT of dinaro, head-scratching, and lost time!
Or, the average bloke, can purchase a properly twisted barrel and, unless he's been fortunate enough to score a hummer along the way, very likely
have the best 6PPC barrel he's ever owned . . . and almost certainly, the least finicky 6PPC barrel he's owned. Oh, there is NO precision penalty/loss via a soundly stabilized BR quality bullet.
Yes, some barrels will shooot better than others: however, ho-hummers and bummers will be a thing of the past . . . amazingly, the lemmings just keep going unquestioningly over the cliff.
The correct question(s): Who do
YOU know who has tried it; Do
YOU know someone who knows someone who has tried it?
