I am trying to improve my groups out past 500 up to 800 yards for target shooting. Have any of you done this and how has it affected your groups? Do you reccomend it or not, and why or why not?
I have done alot of it for 300RUM and 338 and 7mmSTW. Seems the bigger cases, its hard to get consistent neck thickness from cheaper remington brass. Neck thickness varied from .012" to .018". Thats alot but the extreme case. But never take the necks down below .014" in my opinion.
Beware, you might need to use collet dies or redding bush dies after this to get enough neck tension cause necks may be too thin.
Also, it works the necks some, and I suggest annealing the necks after so does hornady, but of course they sell a annealing kit but I agree with em.
Another case is if you have a tight necked rifle built and have to do it.
I have the sinclair Intl. kit and you will also need neck thickness guage to see what your doing. Most people I teach how to do it if they come to my house change thier mind after seeing the time spent.
The kits and time annealing, and etc. cost a pretty penny. I suggest everyone finds some decent brass and cull for neck thickness instead of turning.
Thats pretty well the route I am taking in the future.
Sounds like a lot of work. I am working with a buddy on this since we shoot the same gun.We are not going to those lengths.I think the neck turner is a K and W. Not 100% sure though. It is blue. I am sure there are a lot of them out there.
What we are doing is turning about 180 degrees around the entire neck so we are taking off the high points. To clarify we are rotating the brass 360 degrees in the turner but we are only cutting approximately 180-200 degrees of the neck. Make sense?
What have you seen this do to your accuracy and consistency in velocity?
Shooting a factory out of the box Weatherby 30-378, 180 gr accubonds.
I have been shooting the; 200 gr TSX and groups have been 1"3/4 at 300 yards. I am looking to tighten them up out to 500-800 yards.We are using RL25 and found it is very temperature sensative and we are starting to see some case swelling after 4-5 reloads. I want to do some long range target shooting with it to improve my skills. Hopefully that answers your questions RR. If you have any more feel free to ask.
is your weatherby pillar bedded?
when you start burning over 100 gr charges about any powder will develope some sensativity in warm weather.
In my 7mm Allen Mag I shoot WC 872, its way slower than re25, its a ball powder and also subject to temp sensativity, I just shoot 5 gr less above 70 degrees, and still shoot 3500 fps with a 160 nosler.
Try working up a load with a 200 gr matchking or even a wildcat vld, these are awesome bullets, your shooting .6 MOA out of a factory barrel so don't expect dramatic results from a rifle that hasn't had the action blueprinted. also put a level on your scope/base, that will help a bunch ( a 4 degree cant of your scope can cause a miss on a deer at 500 yds, I know this!)
You may try some retumbo, its sposed to be an extreme powder (less temp. sen.) also shoot heavy for cal hi BC bullets at a lil less than max, Hi BC will outrun velocity every time, and moderate loads shoot better and are easier on brass.

We are now working with Retumbo. I heard the same thing on that powder. Our weatherby's are pillar bedded. I would like to stay with a hunting bullet like the accubonds throughout the process incase I HAVE TO take a long shot to finish an animal I want to know what the bullet is doing.
Back to the subject.....will neck turning (the way I described above) help with accuracy out to 500-800 yards?
To clarify...we are using K and M Services neck turner.

The Wildcat VLD's are great hunting bullets, so are the Berger VLD's. They might at least be worth a shot. I am starting to work up some Bergers for my 7mm rem mag, lets hope they shoot good.

A golf course is a willful and deliberate misuse of a perfectly good rifle range.
well hows your bullet runout? if its within a thou or 2 than no it won't help, if you shoot a 5 shot group whats it look like? are 3 close togather, then 2 close togather away from the other 3?
You may try annealing the necks, that should give it more consistant neck tension. I never turn casenecks unless I hafta, and right now I hafta on one rifle, a 6.5 Gibbs.

Outside neck turning??
