Depends on how much penetration you want/think you will need to do the job.
In the FBI test series it avgs 11.5 pen, .50 exp, goes 12 or over 35% of the time. The +P+ is the same BTW. The 124/147 HS do 14-17 pen, .50 exp, 82.5%.
M&S have the 124 HS at 81%, the +P+ HS at 88%, the 115 +P+ at 93%.
The 115-124s, std and +P, from Rem, Win, Fed, and Speer are pretty much peas in a pod IMO; the differences don't really make much differnce. Use the most accurate in your gun, the cheapest, or flip a coin.
