    I have a rifle chambered in 6BR with an 8 twist barrel. It is throated for Sierra 107 MKs which is my primary bullet.

    I would like to try some lighter bullets for paper punching. What Berger bullet would you recommend to try? If the 65gr BT Target would work that would be great!

    I'd like to try something in the 60 to 65gr range but I have concerns about the twist and throat.

    To give you an idea of the throat, while looking for a heavy bullet I tried some Berger 115gr Target bullets but I had to seat them really, really deep. DTAC 115's seat pretty close to the same place as the the Sierra 107's.

    If your only going with Berger you could try the 68gr fb for shorter range or 90gr bt which
    could go out a little further. I've used 75gr v max in a 124 fb. Had about 3/16" grip in
    the neck with 20 th jump. 5 shot group between .75 to 1" at 200 yds with 6br.
    The 90's shot real well but never tried the 68gr bergers. Not sure how long the 68's are compared to 75 v max. You may be able to seat the 68's as you said the 115's
    had to be seated pretty deep. Might try the 80 gr varmint though.

    Hey Steve, my first 6mm br had a ten twist barrel..That Hart barrel really loved the Berger 88 gr flat base #24323 varmint..I started with the older # match grade for paper punching..I think he still makes both styles..Mike in Ct

    Plus 1 Mike, I had a 10 twist straight 6BR that was great with Berger 80 and 88 gr..Won quite a few groundhog matches with it years ago shooting out to 500yds.

    100 and 200 yards. I am looking to get a feel for Benchrest type shooting without committing to a new rifle.

    I'd like to go light like 65 grains preferred but < 80gr would be ok. I have doubts about reaching the lands so I am looking for some input from someone familiar with the shape of Berger bullets compared to the Sierra 107, DTAC 115 and the Berger 115gr Target I mentioned.

    I had to seat the Berger 115gr Target bullets very deep so a bullet with the same ogive but less weight would probably be the ticket.

    Thanks!

    100-200 YARDS. Try the 65gr BT TARGET or 68gr FB TARGET BULLET. Its a TANGENT OGIVE design and very tolerant of jump. Should be very easy to tune. And at those ranges you don't have to run the bullet fast so you can use a lower velocity accuracy node. My apologies for the late reply.

    80 & 88 gr. Flat-Base Varmint Berger have shot excellent in my 6 mm BR 1-7.5 twist Bartlein that's throated for the 105's. - Seated to where they were right up on the lands (-0.002) and a 32.0 gr. charge of Varget.
