Same boat for me.
30/06 Sherman loaded hot with 200grain'ers and no MB is still uncomfortable at the shooting range,,, not that bad on the hunts since I normally get the critter in the first shot,,, sometimes the second to dispatch it fast... The 2 rifles in 30/06 were 11 lbs,,, the sporter unit was 8 3/4 lbs all in with bells and whistles for each of them...
So I turned the sporter into a 6,5 A Square,,, thickend up the barrel and tap it kool on the charge,,, 11.9 lbs with no MB using a 25" pipe...
140/47gr boolitz,,, it feels like a souped up 25/06 or a tamed down 270,,, what a dream to shoot,,, and shooting free hand is very similar to my Feather 22 rimfire...
I can free hand 5 shots in various targets at different distances from 135 meters up close to 60 feet in 7 ish seconds on closed fist targets...
Add a fraction of weigth to the rifle,,, keep the powder charge in check and find lighter / longer booltiz to Rattle the thick skin critters...
I limited my Sherman to 180gr and liter boolitz with a softer charge at the shooting range,,, but she loaded hot when I take it into the wilds... Ha.
I hope that my 65 pencil boolit rifle works this fall since I have 3 thick skin draws to fill """if""" given to opertunity to pull off a up close and personal encounter...
Good luck finding what works,,, we only get to find out how things play out with boots on the ground.
Cheers from the North
