Hey Everyone,

I am just starting to get into this. I know youve heard that a billion times but, after looking at some peoples recipts on here i have tried stright outta the book. I'm currently loading Varget with hornady 55gr Vmax and WSR primers. Sadly i dont have a crono yet.

First trip to the range was today and it was cold. My first 5 shots were with 25.5gr Varget with an OAL of 2.210". ( i didnt know how to check against the lands before i had these loaded) My gun was way out so they didnt print on the paper. I have since reloaded these to a 2.271" OAL

After I got the gun back on with the cheap factorys i have i shot my last 10 rounds i loaded.

one was 26gr over the vmax with a OAL of 2.230" and they printed a 1.4" group at 100yrds.

the other was 24.6gr over the vmax, OAL of 2.271, and printed a 1.395" group.

I was wondering if it would be the powder amounts or the fact that I am now closer to the lands on the rifle.

Any help would be great, im really trying to get a yote load that accurate and then get into trying my hand a printing very small holes at 300. I dont plan on more than 300 with this gun right now.

Also, what happenes when you compress powder in the casing. I seen that some folks here are using 27gr pushing the vmaxs, but there isnt much room left in the federal/AE cases i am using.

Thanks Ahead of time.

You need to start measuring with a comparator, OAL tells you nothing. Start with your bullets kissing the lands. Find a powder load that produces best groups. When you find a powder load with the best performance, try small groups backing the bullets off the rifling by 5 thou increments. There should be a definite trend towards improvement rather than one good group out of many poor ones.
 
Well - Your experiment is too limited in scope to draw any conclusions.

1) Are you capable of shooting better than 1 moa?
2) The OAL is a "least" variable, dont get hung up on it.
3)Play around with bullet weights and powders - you can quickly see a good load.
4) Learn to be consistent, and take good notes.
