Re: weighting cases
canuk,
If you're anal about it, sort into 0.5 grain groups. If you're not anal about it and just want to sort, sort into 1% of the average case weight groups. Most folks won't see any difference, since you have to uniform primer pockets and flash holes, along with neck turning to achieve maximum consistency. The exception of course, is if your brass has a wide range of cases weights, i.e; +/- 10%.

Re: weighting cases
all has been done
primer pocket
neck turning
flash hole
will go with + and - one grain
thank you DocB

Re: weighting cases
I see you cast bullet just like me
when I shoot cast I do the same thing as you
just started long range shooting
so I tought that it was a good idea
well less work I will drop it
weight them and they are all -+ 2 grain from each other....
long way to go before I catch up to you guys
but I think it the fun of the game
thanks....

Re: weighting cases
canuck,
Best thing to do is load some up and see if it does anything to reduce your vertical spread, which is what you're trying to accomplish. Take about 10 with really close weights and 10 where five are from the lowest weight and five are from the highest weight, then shoot two groups. If it makes a difference, you should see less vertical with the close weights.
You'll find out if your load or you shoots well enough for it to make a difference. Might want to work on both.

Re: weighting cases
will do DocB
also I heard that constant bullet velocity is very important
what powder is good to achieve this
after a search Varget seems to be good
I will be shooting often in the 40 to 55 degrees
and is Bench rest primer worth the extra $

Re: weighting cases
Consistant velocity is what you mean canuck
Everything needs to be consistant in this hobby... if you take away as many variables as you can then you have consistency, and consistant ammo combined with a trained shooter gives accuracy and precision.
Canuck, in regards to your powder choice, tell us the caliber of the weapon and the projectiles you intend on using. Theres a wide variety out there, and depending on availability in your area you may be restricted to only a small group of powders, but hopefully thats not the case.

Re: weighting cases
vman, powder and primer, all available
bullets, Sierra Burger will have to see on that certainly I have more choice
rifle Sako Trg22 26 inches barrel (green) and sako bipod and muzzle brake should be in my hands this week I did not choose the mount yet considering NEAR or SPUHR
bought from Wolverine in Canada
scope also coming S@B 5-25x56 with P4
tell me if I am mistaken Burger seems to be very accurate shot them in my tikka and ouffff clover leaf at 100 yards....

Re: weighting cases
This spring I opened a case of Lapua 6.5 x 47 brass and weighed it all. 1000 rds. to divide and sell to some hide members. Total weight spread was 1.5 or 1.6 grains. I use Lapua and do not weigh now. It is so uniform. Also, I do not think your case prep will gain you anything. If you wish to test, YOu could take the worst bullets, cases, etc and load and shoot against the best at LR and shoot 10 groups with each. You will see no difference IMO.

Re: weighting cases
rth1800
I agree with you
I shoot a lot of cast bullet to practice my form and doing so I have all mix case rem, win, fed, etc and I to have not seen any difference
last night weighted a bunch of Remington and was surprise they where all + - one grain
thats OK with me
taught it made a difference for long range

If all your case are prepped dimensionally the same (on the outside), and some cases are heavier, then its likely that the brass is a little thicker on the heavy ones, which would mean less internal volume. Cases with less internal volume will produce more pressure (and slightly more velocity) than the lighter cases that have a slightly larger volume.
It probably is a waste of time if you are using quality brass, but I did it anyway.... can't hurt, as long as you aren't mixing different lots.
