6BRX, 80 gr. bullet

[bob936]

Has anyone used either 80 grain flat base or boat tail bullets in a benchrest 6BRX with a .104 free bore? If so, what type of accuracy did you achieve at 100, 200 and 300 yards? What barrel twist did you have? I have been using an 8 twist with 95 grain bullets but I believe that the 80 grain bullets may require a 12 twist. The 80 grain bullets are made on a .900 jacket.

I shot 6BRXs also. What is your reason for using the 80 at 1000. Seems to be against the norm of 105 to 110 ? With 106s I expect to shoot 5 shot groups at 100 around a flat .2 as often as not.

Would really like to use flat base bullets at short range matches if I could improve accuracy verses less wind drift with the heavier boat tail bullets.

The 88 gr Berger #24323 is no slouch. It was my Fav. in one/ten twist barrel. mikeinct

Not a BRX, but See ....Advice for first 6BR thread....page 2
FB Berger 80 and Tucker 68 FB shoot great in 12tw....80 gr fb will shoot .25 moa at 200.
I have 10tw that shoots 88's as Mike mentioned above really well! I've heard great reviews on Bart's 80 Dominator

No it will not increase accuracy shooting a fb bullet. You are limiting the advantage of the BRX shooting a 80 gr.

 

[Longrange57]

BRX will certainly handle heavier bullets! However, due to OP....100-300 you will not go wrong with 80 FB or BT

80 gr flat base will work in a .104 freebore

 

[Dusty Stevens]

Check how much bullet is in the neck with a .104 and a flat base. If its not halfway youll need to shorten that freebore and go 12tw for the sweet 80s

I shoot the Bart’s Dominator in a standard BR with a .060 throat. The the junction of the boat tail and the shank is about 1/2 way in the neck.

The Bart’s Dominator is what I call a true short range Benchrest Bullet. It will agg at a sub .200 level. But at 300 yards and shorter, I can’t ascertain any wind bucking advantage over a regular 65/68 grn.
