Trail Boss achieved excellent accuracy with my LHPs but velocity maxed out at 920fps. Not even my 30:1 alloy would expand reliably in wet newspaper at that speed. That's why I made the switch to Tin Star. It would seem finding a suitable replacement might be challenging. I will double check my load notes to see if I tried Red Dot. It might work.
Thanks, Dinny
