Berger 69 gr Hi BC 6mm

[tclaunch]

I have a 6BR 12 twist and no experience with this combination. I read this was an outstanding bullet in their varmint line. Accuracy out to 350 is the goal. Any comments appreciated and welcome.

all I could do would be guess where to start,,maybe you will have it sorted out by the time I can get a bbl,,

from the studying I been doing on it I was told H322 RL10 LT32 and others in that faster burn rate,,

I bet your gonna like it

My local powder supply has LT32, RL10 , and I have H322. Looking forward to this one as something for pure fun to mess with. I know there are many bullet choices, but just am focused on the 69 Berger.

Tim, how long is the barrel on that BR?
Two things you might want to try..... N133 or N135 with the lighter bullets.

And if you have any really good 80gr bullets, might want to run them through there too for a look see. WD

Sir, I think your going to really like em. I just finished up chambering my piddle fart varmint gun. I ordered a .040 freebore no turn 6mm br from JGS to shoot the 60-70 gr bullets. The reamer i got in is pushing the 69 Gr berger around .280 in case neck so i got a little extra boiler room. I started off jamming .020 in with 32.0 gr H4895 and ended up forming at 32.7 4895 cci 250. This is not a real warm load in my barrel which is a 1-12" at 25". I have ran the 4895 up to 34.1 Gr with a drop tube at .020 jam and never got into pressures and had 3550 velocities. 32.5-32.8 is what mine is a liking around 3325 on the lower node with .005 jump. I know the 4895 is a tad slow with the lighter bullets, but shooting very well in mine and got close to a 3/10 node. Bill

It's 24.5". The 80'S will eventually get some testing, just want flat shooting out to 350.

I shot them from a 12 twist 6br.

H322 was the powder of choice and they shot very well from that setup.

Lots of fun inside of 500 yards.
