ORIGINAL: roundball
Yes, I agree it was BS...assumptions repeated often enough over the years become reality in the speaker's minds.....kind of like the old wives tale that 1:48" barrels don't shoot PRBs accurately.
(Cay, from the sound of it the old timer was referring to some other ML longbefore the Omega came out)
Roundball.. I think you're right. He probably seen an old model something or other when they started coming out in faster twists, loaded the wrong projectile and since it would not shoot, it was because the barrel was too soft.
As for that 1:48 joke, people still think that. I just rush into the house and get a T/C Hawkins or Renegade and roundball and hammer the bull for them then....
