What is optimum barrel length for 100-200 yards competition

[marchx]

6BR. 1.25 straight tube.

 

[BRGUY]

21 or 23 inches in overall length.

If you cut your barrels back and re-chamber, then I would opt for a 23" barrel. Otherwise, I would go with a 21" barrel length.

 

[marchx]

how much does velocity matter for short range, e.g. 100y?

With what velocity you can safely get from the 6mm B-R at 100 and 200 yards, it's not going to make a plug nickels worth of difference.

Is there a rifle weight restriction you are working around? If not, go with as much barrel as needed to have a nice balance point on the gun.

It does not say much. I assume any length in the 21”-23” range will give that nice balance.

Should you intend to attend either IBS, or, NBRSA registered tournaments, except in the "unlimited" class, the straight taper is not legal: scope out the rule books. Other sanctioning bodies may well allow straight cylinder barrels. Per Rick (post #5), I'd opt for balance over length. RG

Old School Thinking go 28"or 30" if setting back is in your thoughts ?? More Bang for your $$
I shoot 30" 17 Taper on my Dasher's ?

Not picking on the OP but once again not enough info given for an intelligent response. If guys would give their equipment info plus what discipline or types of shooting they are doing they would get better advice. All I will say is if you try to make it an equipment game you probably will not be consistently competitive.

You are right about the rules. However the club hosting the matches I am going to attend issued their own rules and according to them straight taper is allowed.

Once again thank you. The rationale for the rifle is the fact that I have one spare barreled action “28 6br and decided to make use of it in short range competition.
I am not building it from scratch. I will do some load development and assess whether I could be competitive with it.

24 or 26 would be my choice. You get no points for an extra 15fps. Shorter also means stiffer.

following this line of reasoning: why not 22”?

 

[JEFFPPC]

Or 23, pick one.

In the Houston warehouse experiment, Virgil King said 21 3/4 was the perfect barrel length for barrel harmonics! They did a lot of testing back then and I'd wager somewhere around that length would work well for you! Granted this is for his load. I've also talked to guys who said to use a Heavy bull barrel (1.250 entire length) Keep the barrel as long as possible and if the barrel is a shooter, you can cut some off, rechamber it, and keep using it!

 

[wildcatter]

To use in sporter or Light Varmint it's 10.5# max, complete with scope. With a full bull 1.25" barrel my guess is 19.5" but 19.0" to 22.0" is ideal.

Anyone who shoots and competes in Bench Rest knows this is ideal for annal extreme accuracy. It's also a fact that most top shooters use there 10.5# gun in both LV and 13.5# HV class.

If you want extreme accuracy, don't confuse Bench Rest rifles with Varmint rifles!

Another plus is you are almost a foot closer to the target.

For me balance is the important piece. So find where it balances well with your stock, rifle, scope, etc.

On a gun for this purpose, 100 to 200 yard Bench Rest, with a barrel of this wieght, rest placement and spacing (front and rear) will determine the correct balance.

Again, Bench Rest, is totally different than varmint use. Key word "competition".

I am going to use the rifle also for 300m competition with bipod. My bullet of choice will be 95gr vld- I just have 3boxes of those. I did some modelling and I can push them at about 2800fps with N140.
