beautiful rifle!

Thanks ajax!

Not to brag or anything, but I think the pictures really make the rifle pop. I wish I had some kind of setup for outdoor product studio shoot, it would have been the icing on the cake :)

(I did some adjustments in the post processing of these pictures)
 
Hey Brian.... 4 grains of varget and load the bullets sideways. Don't bother trying it, just do it, I guarantee you will win the mach against Richard :evil: Also, these guns work better with sand down the barrel too.:rockOn:

Um, I would also wash your gun if I were you. I imagine Richard had a hard time explaining the picatinny scratches on his..., well, that was bad enough, but to have openly done it in front of Mick is just plain sick. Anyway, that is NOT cosmoline all over the gun.

Mostly all kidding aside..... It is so nice to see someone who starts off doing things well. Your gun was constructed by one of shooting's best gun builders. As to components, you went top drawer and that is awesome.

I do warn you, Cassidy is shooting with a 6BR now and she looks forward to stomping on you and publicly humiliating you. She was even practicing her Dr. Evil laugh, and from an (now) 11 year old girl, it is pretty funny!

My guaranteed fail-safe load for a .236 bore Krieger 6BR is 31 grains of Varget and a Berger hunting match bullet stuck 15 thou into the lands. Use light neck tension (1-2 thou) and a CCI primer (BR4 or 450) You have chosen the perfect cartridge and some of the best components for mastering precision shooting. The BR is so easy to get working well, and with an accurate gun, you learn to be an accurate shooter.

Richard is correct, there is a 5 and 600M match at Vokes this Sunday and there is a 300 yard match at Mission the Sunday after that.

My $00.02 regarding the scope height... I like a higher scope as it is better for making - and keeping a more consistent cant correction. (Those ACD's the stick up high are the best, as they allow less error... the closer to the rotational axis, the less precise they are).

Welcome to the fraternity, and I really look forward to the $hit-eating grins that are sure to cross your face!
 
I was wondering when you were going to chime in, Ian ;)

I was gonna hose down the rifle because of Richard's indiscretion with it, but the gun looks too nice to bother with (for now). :D

Usually in most competition, a 27-year-old male stacks up pretty well against an 11-year-old girl, but in this case, I sadly admit my lack of skills. But that is to be changed, my friends! There can be no more defeats! :)

I loaded up a boxful of rounds, from 30 - 31.2gr of Varget jammed 10 thous, behind 450 primers. Will definitely hit PoCo tomorrow and christen the BC Roll.

Speaking of seating depth, is there a better way of measuring/seating consistently? Mick and I made a dummy cartridge that had 2.410 at the zero point of touching the lands, but when I did the seating this morning, the OAL fluctuates about 5 thous, sometimes more... :confused:

I look forward to grinning, but do not enjoy eating schit. ;):D
 
If not a diet of excrement, Cassidy will ensure you have a 7 course meal of crow!

For seating depth, get a .243 comparator.... Take a fired case and squeeze the neck slightly out of round. Take a bullet and stick it in the end of the case and chamber it.

Extract the case and bullet, but be very careful to keep it straight as you extract: The ejector will want to push the cartridge out sideways and this will skew your measurement. Gently measure the length of the cartridge, and repeat this several times. This will give you a good "to the lands" measurement".

VLD bullets are very seating depth sensitive, so being accurate is important.

They sure do. Beautiful rifle, I look forward to seeing it (and yes, OK, you too :D) at the Farky.
 
You didn't leave yourself any excuses, though, in buying all that really nice top end gear. Very nice and good luck.
 
Headed straight up to the range this morning (I love how I live 3 minutes from the PoCo range :D).

First shot impression: Wow this thing kicks less than my old 204! ;)

The Sightron scope is pretty good, but today was only out to 100 yards so more experience will be required. As far as the rings height go, right now it's pretty good since I was shooting on the bench today, we'll see how it goes when I start to shoot prone.

Did the barrel break-in procedure as Mick prescribed with some Hoppes and a few patches.

Shot a few groups of 5, and guess what? CyaN1de's suggestion of 31.2gr Varget produced the best group of all (30gr to 31.2gr in .2gr increments). I'll never doubt the man again. :cool:



There is a slight vertical; how does one combat that?

Keeping in mind that this was with virgin brass and my first trip with this gun, I am VERY impressed and there is definitely potential to shrink that group size even more. I can't wait to stretch its legs very soon, perhaps bringing it to Mission (300 yards) tomorrow if I don't have work.

Awesome Brian!!!!

Try messing with the seating depth in and out by .002 increments and the group should tune in.

For example....If your .015 into the lands try .017, .019, .021, .013, .011, .009 (Or use even numbers for easier reference) [EDIT....I see now you had them .010 jammed....go .015-.020 and I think you will crack your face from smiling too hard. :D]

And stick with the 450 primers, I used to use the BR4's and the only difference I can see between the 2 is in my wallet.

Thanks Richard, I'll jam it a few thou's more and give that a try.

BTW, I have 20-30 once-fired Lapua brass from my previous 6BR lightweight rifle. I think I know the answer to this, but just wanna confirm: if I load these brass and shoot them in my new rifle, these brass will be fireformed to the new chamber, correct?
 
A fantastic start with new brass. Just redo with the new fireformed stuff and the groups will sort themselves out.

Small changes in case expansion during forming will have the same effect as varying your load charges or seating depths so I don't put too much thought into the initial results.

I look more for pressure signs and of course, interesting nodes. Once all fireformed, I get serious about testing.

I bet with the FF brass, you will see the groups settle down. I vary my charges in very small increments vs changing seating depths.

Works for me

New Lapua 6BR brass is absolutely outstanding. I have shot some of my best scores with virgin brass, and I have seen no real difference in final results between virgin and 1F brass. I won the Lt. Governor's prize shooting virgin brass that wasn't even weight-sorted. I don't think it is necessary to sort, as Lapua is just that good.

Your 1F stuff will indeed be fireformed to your chamber after the first go.

Run the already fired brass through your body die (assuming you are using Redding Comp) or FL Sizing Die and then load as normal.
