20 tac is superb. you don't need to case form for it if you dont want to. as you can buy 20 tac brass over from reloading solutions, midway uk etc. it is Dakota brass made by lapua so its top brass.
two of my mates have 20 tac's and one has a 204 there really isn't much in it between them. one is for sale though has he is giving up shooting due to losing local permissions.
pm me if your interested. its a semi custom 20 tac with redding comp dies, cleaning kit,etc etc.... all for the price of what a standard sako would be in the shops these days !
