6 BR 1/14 twist

[Gsidden]

What velocities are you or anybody else getting with this combo in a 13 or 14 twist, 24-26 inch barrel?

I’m at 3150

the reason for me to get a BRX is to have the juice to get 105 class out to 1000! for that seems like i should use an 8T or mabie 7 1/2. what you say Ackleyman???

PS. my 6br will do it but i can definately see it losing steam past 600

Quite a few records have been set with 6BR at 1000 !

true and that encourages me to see what i can do with mine, and another one im putting together, at 1000. I dont have plans getting any of the “improved “ variations at this point—- thanks

All I own are 6BRs and I totally agree with you on the variants . IMHO they are over rated .

IF, you can switch to AA2230 or H335, you will more than double your barrel life vs R#7, I learned a hard lesson this way. N130 is also very, very accurate along with H322 but they too eat up barrels faster than AA2230. Lot# of this powder vary, but the Accuracy node in a 27", 12T, zero freebore is 3930 or there abouts where the groups at in the 3/4" area at 300 yards.

I wish you the very best. If you decide to get teh 6 BRX there is no down side, add another 200 fps on all bullet weights. I have the Dasher with slow twist and .020 freebore also, and much prefer the 6 BRX over the dasher. For the BRX, you can buy the 6 Dasher brass, run it through the full length BRX sizer, and have a perfectly formed case!

As you know, the 55g Nosler has a better bc than it's 22 counter part, and with the 6 BRX, you are beating teh 220 Swift in ballistics. I shoot the 70 blitz king at 3700 fps plus with H335, tiny groups with rem 7 1/2.

Al, I realize that I am preaching to the choir here, just thought I would pass this along.

Years ago the rabbit population was in it's up swing. I ran a 6 BR Reamer in .100 deep after a fellow in Ga. recommended it to me. All we had was Rem brass but the ballistics' were incredible, with me being able to shoot the 60g Sierra at 3850 with the Remington primer pockets staying intact.

Does anyone have any information about the effects of IMR 8208 XBR on barrel life compared to H-335 or H-322 ? Ackleyman , chime in here and educate us please. 8208 works really well in my 6 BRs as well as my 6 GT with the 70 Gr NBT...

What is a good bullet weight for a 6BR with a 1/14 twist?

Did you ever say what you wanted to use the rifle for? For strictly accuracy BR type shooting I always had great luck with N-135 and 65-68gr FB bullets. Recently been more interested in varmints and ended up with TAC and 65 V-Max @ 3600+ from a 24" barrel.

 

[JoeDuke]

With a 14 twist, keep the bullet length under .825.
One particularly great bullet is the BIB 65 gr on the .790 J4 jacket.
Good shootin' -Al

Pay attention to this post if you are doing any competition at all.
If not competing try most of the 58 to 68 grain bullets recommended above.

Would AA 2230 powder work well in the 6bra with an 80 grain bullet in a 12 twist barrel with .60 free bore or are they better powder choices / options considering easier/better barrel life and getting more velocity?

 

[AckleymanII]

IMR XBR 8208 burns very HOT! I shoot this in a Rem 700 SPS in 223 with the cci 450 and 55's at 3450, hammers hard and shoots very tiny groups.

However, the 8208 due to the Heat Index of this powder, walks the throat out pretty fast, noticed this issue using it in my Krieger 308 also. H4895 is also hot as hades.

My 6BR is 14 twist, 24” long. Zero freebore. This is for vamints. Likes 55 to 65 gra bullets, probably 70 TNT also but don’t remember trying them. Load development was all done back in 2004 and 2230 proved to be the best. The stuff can vary and production may differ. Chosen load is 2230 powder, 7-1/2 primer, 58Vmax. Accuracy nodes at 3708 (.250”) and 3855 (.200”) . I don’t mention powder charge because 2230 can vary and this was 20yrs ago, plus that 3855 is a hot load but fine in this rifle.
