Good morning to you sir, I trust that this first Sunday in November finds you doing acceptably well.
With apologies to those who've already read through this thread, I'll link a good discussion we had last year regarding the capabilities of the old Swede military round.
https://www.24hourcampfire.com/ubbth...ssue_Damage_-_.270_vs._6.5x5#Post9248055Shortly after finishing that thread I went into the garage, set up the barrel vice and twisted the action off of the rifle being discussed as I'd found a gunsmith who agreed to try an idea that the retired smith in the Kootenays had suggested.
That is to install a bushing on an original military barrel from a 96 and thread the bushing to fit a 98 action - which is what was done. I should note this wasn't/isn't the inexpensive way to go in all likelihood, but I wanted to further play with a deep groove, fast twist barrel and the military ones were both.
I've since shot a second rack mulie buck - 116lb carcass weight - maybe 150-200yds - with a 120gr TTSX that exits the 21" barrel at 3000fps. The bullet struck where I was aiming - right scapula, roughly 2" above the joint with the humerus, then took out a rib, traversed both lungs, took out another rib and exited.
The buck was at a mineral lick when I spotted him and this was one of the very few times in my experience where the animal was very much flipped onto it's back with all four feet in the air - and stayed there. Well it had rolled onto it's side and was very sincerely dead when I walked up to it.
There was one shard of bullet in the meat on the entrance side which weighed 3 grains and another on the exit side that peeled off and made a dime sized exit hole in the rib cage before lodging under the hide - it's 5 grains.
Lastly as you can no doubt infer from the linked thread I am one of "those" folks who do buy into the idea that twist rate is a factor in tissue damage, especially when coupled with bullets which perform well either with higher initial velocities, higher rpm or both.
Hopefully that was useful information for you or someone else out there this morning sir. Good luck on your rifle choice whichever way you decide and all the best on your remaining hunts this fall.
