Iím not surprised that itís shooting well for you at that velocity, 2850-2950 seems to be the sweet spot for 105s in the BR variants. Iím with you, Iíll take 1/4 MOA over 100 FPS. Iíve got a 7 SAUM that prints 5 shot groups under .2Ē at 100 with a 168 at 2860 FPS. Itís well below the performance I could get but it shoots so well I just leave it alone.

This was the speed today over the chrono when I went to sight in a new scope and check the powder charge. Shoots very well at this speed and holds accuracy well out to the 1000 i shot today.
Struggled a little while zeroing because the scope has 1/4 mil hash marks and I was thinking they were 1/2. Took me a few shots to realize why it was over correcting so much every time.   :chuckle:

chris doesn't zero with chrono attached I'm quite certain.

I can assure you I do in fact know how to zero a rifle. Believe it or not...  :chuckle:

I typically donít but with this gun for whatever reason it makes exactly zero difference with or without chrono.

I shot it both ways at 100 yards today and the zero didnít change.

The 0.95 inch muzzle diameter might have something to do with it.

Just trying to help. I learned that the hard way a few years ago.

I took the 6 BRA out last Saturday and did some powder testing along with some scope tracking/poi testing.  First time out with powder and shot a nice 1/2" group at 300 yards.   I will be taking it down to the 600 yard match in Eatonville in a few weeks and see how it does.

Just about anyone would be happy with that group at 100 yards, let alone 300.  Nice job and well done!  :tup:

Itís slightly under 17 pounds and is a full on bench gun.  I was really happy about it to.  First time playing with it.  103 Vapor Trials.  About 2930.  There was some worse groups with lower powder charges.  But only show the best ones!
