Been tinkering with the tsx in my7 mm STW with 140's and 168's in my 300 wsm
. in the STW usually holds around 3/4" but no matter what i do nothing better. in the 300 they are extremely in consistent. best grouping is with 63grs of H4350 just under 3/4" unfortunatley you can take the same recipe go out the next day and get 1". Accubonds shoot well in my STW and have yet to try them in the wsm any thoughts. Would also like to try 150's in the wsm as well.
