Brass Prep for long range accuracy

Here is your custom die - for a lot less than $500.00. Best money you will ever spend. https://www.whiddengunworks.com/custom-reloading-dies/

Another great option, but not available in some calibers. Give them a call. Great people to work with. http://harrellsprec.com/index.php/categories/reloading-dies

Then get yourself an arbor press and one of these seating dies. https://www.brownells.com/reloading...hamber-type-bullet-seater-dies-prod36168.aspx
These are pretty interesting. I have a forster shoulder bump die, full length, and bench rest seater. Also sinclair neck expanding die. I can get less runout with the fl die without the expander, and expanding with the sinclair die, than using the bump die with bushing. RCBS press. Are you using their bushing or solid die? What are you seeing in runout in the finished cartridge? And what press are you using?
 
Just putting this out there. 40 years ago it was pretty much rcbs dies or custom. I was taught this for standard rcbs dies, and you can load some pretty accurate ammo this way... set up the sizer with a nickle of clearance between it and the shell holder. Size a case and see if it will chamber. If not, lower the die until the bolt will close with some, but light resistance. Set up the seater normally but only seat about 1/3 the way. Turn the case about 1/3 counter clockwise and seat about another 1/3. Repeat and seat to final depth. Much easier to do and show than type. You would be surprised just how good ammo you can load with standard dies, partial resizing and then seating this way. Bolt action rifles only though.
 
5" groups at 1000 is an accomplishment to be proud of. I have a .308 that will shoot in the 0's at 100. If it would hold to 1000 I could win world championships with it. 5" @ 1000 is good enough to hunt deer that far if you can duplicate it from field positions. I have spent a small fortune on rifles, reloading equipment, and components, and am a pretty good shot. I know full well that is very difficult to do with a rifle that retains enough energy that far tohunt big game. 700 is tough enough. AND I am talking about consistant groups, not just one that sometimes happens at any distamce. If you cant back it up on different days it is just bragging.
Exactly. Depending on temperature humidity and altitude my groups range from 2 to 10 inches or 1 moa. If I can't dope the shot I don't take,it. Usually on elk. Deer are almost,always under 600 yards.

Yes you can. Well said
 
True story. It took me a long,long long time to even attempt 1000 yards. I was intimidated to tell the truth.
 
Some are consistent and repeatable.
This is my .280AI lightweight hunting rifle. 175 Elite @ 2975fps




545 yards


851 yards



921 yards


921 yards, 5 shots.

Bushings. Have a Harrell's press for smaller cases, Redding Big Boss for longer cases. Arbor press with Wilson dies for seating. I don't check run-out any more. Only hunting and not shootings competition. My run-out gauge setup is gathering dust.

Over the years I have bought and tossed a lot,of equipment. I do like my Franklin Arsenal her as,prep station.

40 years can pass quickly.
 
Can anyone say for certain that these guys who full size are using a custom die that is very close to their chamber dimensions?

Also do they use a neck bushing in the custom sizing did?
I don't even use bushings. I only full length size new brass. After that I neck size only. There are good died out there but I only use ( Redding Premium Die Sets ) it's the black box. I get 5 rounds in same hole in my 260 Rem,243 Win, 22-250, 6.5 Creedmoor, 220 Swift. My 7 Mag and 300 Win Mag I can get under 1/2" 5 shot groups. Sometimes 1/4" groups. I've shot all my guns at 1000 yards. My 260 Rem, 243 Win, 7 Mag and 300 Win Mag I have shot past 1000 yards. I just don't see how you can shoot better than hole in hole.

Eventually you'll need to bump the shoulder, it's inevitable. If you're throwing you're cases away after 3-5 reloads I guess you can go for it. A 300wm will grow ahead of the belt within 5-6 firings to the point of needing FL sized as well. I have rifles that unless I bump shoulder, once fired brass will not chamber, and it's not the neck. Going around touting to just neck size isn't practical.

If this is the case why are you not cleaning up the benchrest circuit?
