hey yall, new guy here!
i am considering a 20" .264 barrel for my next build, but a major factor i'm thinking about is weight vs accuracy ratio. this rig will be mainly used for stalk hunting out to 400 meters, so weight is a factor. i'm pretty set on a 20-22" barrel.
anyone know what the weight diffrence is of a spiral fluted 20" bull versus a standard contour 20"? i know the accuracy nod will go towards the bull but if it is significantly more heavy, i'll go to the standard profile. most shots will be taken from a cold bore.
thanks!

Hi Rusbellows,
First shot accuracy is not affected by the profile (thickness) of a particular barrel. The bull barrels have more mass and larger surface to dissipate heat than the standard, light, and pencil barrels and therefore when they get hot (after repetitive shooting) are more likely to keep the same point-of-aim- point-of-impact. If you are going to be shooting more than 12 rounds/min then the bull barrel is what you want, but for your description of the purpose for this rifle I would lean more towards the standard or even light profile....it seems you will be affected more by carrying a heavy rig all day than by the change in the point of aim when the barrel gets hot. Personally, I think it is more important to be familiar with your weapon and every shooter should know how the heat of repetitive shooting will affect their rifles. That way you can make the necessary adjustments rather and be surprise by deviations due to a hot barrel.
22" standard profile barrel with target crown will make a great and accurate rig. You can make it lighter by fluting it and it will still be stiffer than a light barrel of the same weight. Just my .02 cents.

I have no idea on the fluting weight difference but I would go with a standard profile 20" vs the bull on a stalking gun. I think that would be a great information table if they could do one up. Remember the DCM boys shoot plenty far with those non-bull barrels and do well.
The ones you have be reading about here on the board are all standard contour not bull barrels and they are shooting very well.
I think you will be pleased with your caliber choice.

hey greg, would you guys be able to fabricate a 22" standard profile? if so, how much extra $$$ would that be?

hey greg, would you guys be able to fabricate a 22" standard profile? if so, how much extra $$$ would that be? ;D First of all I'm on the Pro Staff. That means I'm a bit more involved as a shooter and a resource for you guys on the board. I'm not involved in the production end as I am in Phoenix. If I were at BHW I would spend every penny of my wages on their goodies!! Now looking over the price sheet I bet you dollars to donuts that there would not be more than a $10.00 extra charge for the 22" tube if anything. I would call BHW on Monday and get a quote, drag my heels and place my order during the January Special. 15% is nothing to sneeze at. Let us know what you do because I get as much of a kick out of other guys acquisitions as I do on my own. I guess that's why I share my new ones. Greg |

haha, sorry Greg! just kind of assumed you were on the payroll because you seem to know a ton about BHW hahaha.
well, i'll be damned... did not know about the January discount! sounds awesome, if i can combine that with the LE/Mil discount, there is no reason not to jump on it asap. i think i made a decision on my barrel then; it's gonna be a standard profile 22" with spiral cuts, target crown and bead blasted. i'm going to throw it on a LAR ops-4 side charging upper. i'll have to put it together part by part (to keep the wife from going cyclic with the frying pan to my noggin), but i think it will be worth it. i'll keep you all posted!

Cyclic? Is that where she hits you once, winds up hits you twice, waits a minute hits you three times and FINALLY hits you four times for a HOME RUN?  Greg PS: Good choice and that will be one cool looking rig. |

My wife cyclic rate of fry-panning is the same as the M240G Mideum Machine Gun (650 to 950 round per min, depending on the gas settings).
I feel your pay, brother.

Hi,
Actually the concern should be more of weight vs. speed.
All other things being equal a shorter barrel is a more accurate one. this doesn't mean than a longer barrel cannot be very accurate or even more accurate right off the bet but might be more picky with the loads on average. 20 inches is good, 22" is good too, beyond that ,the pole factor starts to get noticed.
lighter profiles and/or fluting always help.
The purpose is the main thing that helps define the ideal setup. It is always a world of trade offs.
I hope this helps.
