1st of all I've got to say thanks for a great forum, I've learned a great deal about this hobby from the many pages here.
I just starting to get into reloading. I'm loading for my Remmy 700 .270 Win w/ a 24" barrel. So far I'll be loading w/ new Win cases, BR2 primers and 150gr Berger VLD's.
In the morning I'll be headed to the range w/ my first 24 hand loads to try the "Jump Test" from the Berger site, with seating depths: .010", .050", .090", .130". All w/ H4831SC.
My question is which order should the following variables be tested to minamize loads required to find the most accurate load?
1. Seating depth (I'm guessing move'em +,- .005" or .010" after finding the best depth tomm?)
2. Powders (I've also got IMR 4350, RL 19) <thus 3 different powders>
3. Powder charge (guessing +,- .5gr?) <from 54gr to ~56gr or 58gr w/ H4831>
4. Neck tension (is this normally tested for accuracy purposes?) <I've got .300", .301" and .302" neck bushings>
I just can't see having to load hundreds of rounds just to find the best load w/ the same bullet, case and primer.
Is there some of those varibles that affect all the others and should be tested first or some of them that do not affect any of the others and should be tested last??
Sorry about the confusing shotgun blast of questions but I'm pulling my hair out trying to find some science to this madness w/out max'n out all the VISA's :(
Just trying to make the most accurate long range HOG BUSTER I can
Like I say I haven't even fired my first reloads yet so any and ALL info is welcome and appreciated.
P.S. On tuesday I sent Berger an email request for load data, still waiting.
Happy Independence Day!
