i have only 3 SMR builds, but a nice little round forstaock looked best to me...they are THIN in the buttstock area....neither near 10#....in fact until someone shoulders them, they think they are 'childs' rifles.
small calibers, small barrels, iron funiture, cresent buttplates, no patchboxes...thinthinthin.....
'V' shape could work also, I just liked the oval/roundie type...still only 1/8" thicker than the barrel, and the wrist barrel+1/4" thick....then all tapers back to BP...
and...spend a little time, and put that 'lollipop tang' on it.....really dresses it up~
just have a 'cuss jar' ready......youll need it!
