WOOD LIKE TO SHOOT LONGE RANGE 800 PLUS BUT WILL SHOOT ALOT OF 300YD
HELP PLEASE ....
DISCARD AND START NEW LADDER TEST ???
never hear guys running 32g of varget in there 6mmbr
should I go 29.5 down an look for a node ???? help

Either I've missed some info or I'm blind. Are you shooting a 6BR or a dasher? That 32 grn load is dasher territory and no way is a 6BR gonna take those pressures. Usually 29.0-29.5 is a good 6 BR load.

James you gave me a little scare there. I am testing near 34 gr of varget 14 twist and a 68 gr bullet. Rem 700 action. Primers cci 400s look fine. No bolt click. Did you state that because of the 105 bullet ? My ladder didn't flatten out until 32.2gr. at 300yd.

thanks :

this seems to be a theroy that is all wet...Tell me..If a load isn't gonna shoot 10 shot bug holes at 100 yards,how in hell is it gonna be good out to 1000...?

When I first got into the 1000 yard game in Williamsport,PA I had been shooting at 100 yards..And I won my very first relay there...I was sighted 27 1/2 inchs high at 100 yards,which was dead on at 1000....This was a 30-338 with 190 sierra match bullets and if I recall,something like 2900 fps...So I say your theroy is all wet...And I still do my load testing at 100 yards with my 6BR..i KNOW this is gonna piss some of you off...But I know...Have been there..This was 30 years ago....

How about me ?

Steve, I base my loads and equipment on the most controlled conditions i can get at 100 yds.. Even though i am using the same loads from last year i still go up and down on powder and in and out on seating depth and go to different neck tension. I don't want to leave anything on the table….. I had scope problems this year but that is behind me, and it proved it out on the last match.
I don't believe in ladder test, nor do i believe in mid or long range tuning but it is called a cone of dispersion and it will be at it's smallest at 100 yds. If i have a .1 or less gun i should be able to tune at 1" or less at 1000 and enhance it from there if all the tuning at 1000 and ladder test work. They can't because of the unseen conditions affecting you group. So i will guess i will muddle along with my out dated way of doing things…….. jim

I know, Jim. Just a little sarcasm. I do all my load development at 100 yards over a chrono. Targets are measured using On Target and a flatbed scanner, producing very accurate results and some useful data. My last .300 WSM barrel, when shooting my twenty-five shot validation string, shot a .218" agg of five 5-shot groups, two of which were in the mid .1's. The ES range was 5.9 to 8.8 for five shot groups and 12 fps for all twenty-five. That string was fired in 12½ minutes. The load, 230 Hybrids at ~2865, performed very well for me at both 600 and 1000 yards, holding excellent vertical. I, too, will continue to do it this way, because it works. [br]
Several times per barrel, I'll take a few remaining rounds after a match and shoot over the chrono at 100, assessing performance and ensuring that all is still well. If there is any deviation from the previous results, I determine why and, if necessary, run another series to correct it.

Steve, You hit the nail on the head….. Repeatable 5 shot groups 3-4 times is my way, that way i can also see if heat is moving the groups…….plus ES. and group size. ……. jim
