well she's a keeper. worst group was 1.125, best was just under.625 . POI didn't really change as it heated up but group size did. She sure does need a new trigger . I had forgotten how bad the stock stuff was.

Years ago I bought an AR in an 11.5 pistol. I put about 2 mags through her , and shes been in the safe ever since. Over the years I have ended up with a few extra pieces, But Today The UPS man brought me a 18"WOA SPR barrel. I had completely forgot about it since it had been order 5 months ago...

Re: tubb final finish kit its a remington model 7 in 22 250, has about 3 boxes through it. its awful to clean too, scrub and scrub and always black residue coming out on the patches. Thought about a rebarell to 6mmbr, and still might. just thought I could try the ff kit to see if it would help.

anyone used one of these kits, What do you think? . Good, Bad, Ugly. Im thinking of using one for a so so shooter of mine. never does better than 1.25 at 100. Clean or dirty and no matter what you feed it.

Re: siera 69gr 223 load OK I ordered a chrony, now how do I use it to get an accurate load? Am I trying to copy the load data Velocity? I understand ES and SD, I think. what is considered acceptable ES, the more es you get the wilder the load right?
