Glad this came back around... Yes, the above load is a very Good one...for Me, with softer 230-240 gr Boolits.
But, with the Lee 255 SWC there is alot of Boolit In the case, so 5.8 gr of Trail Boss is where I settled (based on available powder space)
Yes Very Soft Shooting... But, with the Contender, sweet shooting.. Haven't shot them with the SBH, but, Might be Fun in that... tho 200 gr Rf, over SR7625 is what it Likes
