It appears that nobody has answered your question so I'll speak up. I do not know how much handloading experience you have so I gotta give the generic response. If you are a seasoned loader, then you may not need to keep reading. If you are a nu-b, read on.

It sounds like you have the components lined up, but when it comes to "What is an MOA load", well it doesn't quite work that way. You might get an answer from somebody else that may work just as well in your rifle, but you may, get a load that patterns instead of grouping.

Generally, you look for a starting/finishing load and look for your rifle's sweet spot in that range.

according to Hodgdons 2014 manual - m Oops, I reread your post and saw you have 139 and 154 bullets, I thought I read 162 for some reason.

I'd replace what I originally said here with a link to Hodgdons site.

If it were me, I'd work in 1/2 gr increments through that range. I'd load 3 rounds of each and test shoot those rounds looking for a sweet spot. If I find one load that is clearly the best, then I'd load rounds .3 up and .3 down from that load in .1gr increments.

It's a lot of loading and shooting, but when you are done, you'll know what works in your rifle. Good luck and have fun

Thanks mt sourdough I took your advice and did some different loads with very small changes in the charge and went from just about 1 inch to thispost-5984-0-17633300-1400734244_thumb.jpg

 

Thanks for the info and push to give it one more try. With my new weaver grand slam I will knock them down

Very nice group Sherman.

What ended up being the 'perfect' load combination and COL?

Great advice MTsourdough!

It was 59.8 gr imr4350 cci mag primer and the COL was 3.290 it should be somewhere around 3000 fps. Now I am glad no one traded. I had gave up with this gun til this. And my dear friend hoghntr found me the scope at a great price. Dang now I wanna go shot some 400-500 yarders
