The BH 50 TSX has an expansion velocity threshold of 2300 FPS.
The Barnes 70 TSX has an expansion velocity threshold of 1800 FPS.
Given this, I’m trying to figure out the maximum distance for expansion with the following barrel lengths:
50 TSX (Black Hills)
11.5”
14.5”
16”
70 TSX
11.5”
14.5”
16”
Any and all help would be greatly appreciated. Trying to find the most optimal barrel length and ammo combo.
Some one of the TOD did some work ups on this. I have the spreadsheets saved. I’ll DM them to you later today/tonight.
AQ planned for years and sent their A team to carry out the attacks, and on Flight 93 they were thwarted by a pick-up team made up of United Frequent Fliers. Many people look at 9/11 and wonder how we can stop an enemy like that. I look at FL93 and wonder, "How can we lose?". -- FromMyColdDeadHand
