    Just another suggestion, but if you can get Quuckload, try tuning your load to the OBT (optimal barrel time). I've done this with 2 different rifles now and amazed with the results. Have a M38 in 6.5x55 that was always throwing a flyer. After many different attempts at trying to fix the gun (stock, crown on the barrel, etc...), I was convinced the barrel was shot out. Once I started getting better using Quickload I was able to tune the load to hit on the OBT node. The gun now shoots .4 inch groups consistently. All I do now is tune the load for temp swings larger than 20 degrees.

    I am getting really frustrated with the information being given with the use of acronyms. What the heck is OCW?. Post in front of mine wrote out what his acronyms is. I want to use all the information given but so often it is written in a foreign language.
    Please put the information out there in a manner that makes sense and is usable to the rest of us unwashed and obviously ignorant loaders.

    Not to be condescending, but Google is your friend. Until such a time as we get an acronym decoder stickied (maybe a good idea mods?), your best bet is to type in a search on your favorite search engine. "OCW reloading" will get you all you could need and more.

    It isn't optimal, but this is a fairly technical hobby-oriented forum. You aren't going to escape the jargon.

    Having been a reloader for over 45 years I did not realize that acronyms were the only way to describe something. I have a fairly decent understanding of reloading but don't understand the need for acronyms that may have multiple meanings when dealing in a technical situation.
