I have used the sierra .243 107 in my old Remington 788 with 1/9 twist barrel. 22 inch barrel.
My load is "work up" if you try it...reloader 19 = 44 grains chronographed 2960 fps...win brass and win large rifle primers.
Have not played with the 107 in years.
Go out and try some...let us...
I have done the .355 in 38 special. 125 lead RN well they are .356. Light load of bullseye or titegroup and your good to go. They have worked well in my S&W 637 and charter arms off duty guns.
