6MM Dasher barrel length question

[40X Guy]

Looking at building another Dasher and was wondering what is the general consensus on barrel length? My first Dasher's barrel is 30" finished. I have 2 blanks one being 31 and the other 32 inch. If i use the 31 inch blank what is the maximum finished length for that particular (Bartlein) barrel. Can I squeeze 30" finished out of it or what would be a good length? I am thinking barrel nodes and have definately found the one for my first Dasher.

Frank ,
The guy's I shoot with are claiming 28-28.5" is the magic number for a Dasher.

26 inch doesn't do bad. I thought bbl length and powder burn rate should work together. Varget and RE15 shouldn't need a real long bbl. I may be wrong on this just my opinion.

You'll get about 30" out of it finished. What do intend to do with it?

I have a 28 inch Broughton, a friend has a 32 inch ?. He shoots 50 fps faster. I have a 28 inch krieger that is 125 fps slower than the Broughton. Didn't anwser your question but food for thought.

I'm at 29" and the talk is anything longer is just added weight.

I have 2, 6 dashers one at 28" the other at 30"

As well as a 22 Dasher at 30"

If the 30" tubes are too long they will be perfect in a rechamber or two......... ;D

I concur, I have had fine results with the 26" tubes and this allows me to make weight.

Thanks for the replies everyone, at least I know great barrel life is there. Currently shooting mid range BR matches at 5 and 600, and looking into the 1000 yard plateau next year. I am going to go with another 30" finished Dasher on a Pierce action and at least I know I can always cut and rechamber or set back down the road.

Frank, I went that route before 30" set back too29" but the lands are rounded,i don't know if it is worth it. It still shoots but it would have if i didn't set it back. I now plan to go with 28" i don't see a big gain in speed over 28" and they are hard to make weight and balance but what ever works for you is the right answer....... jim

I really think i'm going 26" this will be my first 6 dasher.. I want to use it as a 600/1000 light gun and also a live varmint.. I have had a 28" barrel'ed 25/06AI and just never cared for the extra lenght..I have had a few really good shooting 6 BR 26" barrel's .. so i said i'm going to due 26" and i can see most are useing 28" .
do you really think i would be hurt with a 26"?

No, I'm running 107s @ 2985fps and very accurate out of my 26in

I rechambered a 30 in. Brux no taper to 26.5 in. to make
the 17 lb weight limit. Had to go this length to get under
weight with a muzzle brake.
I was pleasantly surprised to see 2904 fps with the 115 DTAC.

I believe it was 2007 when the small group record in IBS 600 yd
matches was broken 4 or 5 times. Each time the barrel length
was 28 in. Larry Isenhour, Rodney Wagner, Mark Schronce, and
maybe Sam Hall, Richard Schatz all held the record for a few weeks that year.
The record shrank to under one inch.

For a while the guys Piedmont guys went to 30 in. but now most have returned
to 28 in.
Good thing is at 28 in. you can still get a rechamber or two.

Birdog, thanks for the insightful post, my smith also agrees with 28 finished length. I should still be able to get to that 3025 fps level with no problem. Good thread with real world replies and I thank everyone!
