Bullbarrel?

DocHolliday331

Please tell me - what is the significance of a "bull" barrel. I know it does not require bushing but other than that I know nothing. Is it accurate?

Mr. Lobo

It is my understanding that there are two advantages you gain with a bull barrell. One is better heat transfer so you bullets will keep better percision durring continuous fire. The second has to do with harmonics that are created when the bullet is fired throught the barrel. The barrel actually whips which in turn looses percision. The bull barrel's larger diameter aids in minimizing this problem.

I'm not sure if we're all talking about the same thing. Was the original question about a "bull" barrel in a colt 45? If so , the significance would be entirely different. In that case, the barrel is made larger in an effort to dispence with the barrel bushing.

all barrels have a whip when a bullet travels down the rifling. The amount of steel around the bore, will have a rating of how much strength it has. This rating is refred to as "tonnage". The tonnage of a bull barrel is considerably more than a standard barrel, and therefore, it requires much more pressure in the bore to create a whipping or vibration while the bullet travels it's length. This in turn forces the bullet into a tighter spiral, and therefore a tighter group.

A great rifle with a junk scope,....is junk.
