ok i have a bit of a rant it seems all these bench racers on here cant pony up real advice, it seems you have always answered my questions unbiased and truthfully, the question is about the 7mm ultra mag and your 7mm AM, i would like to build a new ultra with a 28" tube to shoot the 168gr bergers or wildcats when or if they become available again this would be my muley/light game rifle, what velos should i expect with this weight bullet and and bbl length? it should be suitable for light deer muley and under to 900yds right? i know shot placement is critical at any range. ok for question #2 your 7mm mag and 200gr's in a similar 28" bbl gun what twist would i need for 200gr wildcats? what velo should i expect from that combo to i have seen some posts of yours but do not recall all that good info and i will go straight to the horse on his on stuff. any help would be appreciated, also do you have formed brass available for the allen mags? i know the 7 is based off a 338 lapua and is shortened, as you know when hunting out of country it helps greatly to have matching headstamps and bbl markings.
