has anyone had any accuracy changes with cfe223 when the temp goes from the 80s to into the 100s . I went from .5 groups to 1in. groups when the temp went up

My gun didnt do very good for the first 100 or so. keep shooting and cleaning it will get better

I use imr8208xbr and get ¼ in. groups with the 50 gr bergers in my 1 in 10 twist

I had a rem 700 with a 1 in 12 twist that didn’t like anything bigger then 32gr . I now have a white oak AR .204 with a 1 in 10 that likes 40 and 50gr

i did the same thing lol. the next upper will be a 6.5 grendel

i have shot 500 rounds through my ar. i am happy to say i have tried three different weight bullets and three kinds of powders. it likes them all. my starting 100 yrd groups were 1 in. now they look like clovers

my upper came in the mail today!!

bow shot what upper did you get?

update on my upper, I call and they told me three more weeks (one week ago). talked to euro optics they got me a vortex viper pst ffp 4-16x50 in the mail should have it by fri.

i dont have the upper yet. when i called them they said two more weeks. it has been six weeks so far.

i got a RRA lower and a White Oak Armament .204 upper in the H bar contour to take a little weight off.
