You better start over, as you completely missed the bullseye. LOL You would not believe how many inexperienced &/or non-shooters have told me that over the yrs & why I seldom show anyone anymore. Talk about making me speechless!
Anyway, yep, looks like your there. IMR 8208 XBR is a great powder & friends & I have had excellent results in both our 223 & 22-250's with it. Except for my
223 that is, which only reconfirms that each gun is different.One question. Did you subtract .308" diameter from your over all .625 score? It appears you arrived at that # measuring from outside to outside? That group appears MUCH smaller than .625 in other words, but pics can be deceiving however. Always nice when finding a great load.
