All I know is that is what I have used since getting to Texas in March 0f2022. Best cartridge for just about everything i have or will hunt. It is a Savage `110 in 7mm-08. I have shot 2 bucks and 4 wild pigs/ feral pigs. Every single has gone down with one shot. All of them but the last deer went right down. The last deer walked 30 to 40 yards and dropped. My 7mm-08 does the job right.With the new calibers coming onto the market , are my old calibers suddenly obsolete ? My 250 Savage, 22-250. 6.5x55, 270 Win, 25-06 7mm-08, 308, 30=06 will they not do their intended job any more ? Your thoughts please.
