Ramblin_Razorback: I have some extensive firsthand observations regarding a SUPERB 223 Remington factory offering for Deer/Antelope and on one Mt.Goat! This factory offering is the Remington 55 grain PSP (Pointed Soft Point) cartridge. I have seen this round kill NUMEROUS Mule Deer, Whitetailed Deer and Antelope literally in their tracks! This includes a 31" (very mature) Mule Deer Buck killed with one shot! It appears your interpretation/conception of lethality is premised solely upon bullet weight - it's not. Lethality is premised upon a well placed shot and the proper transfer of a proper bullets energy (explosive or shocking power) inside the vital heart/lungs area of said game! I have a friend here in SW Montana that for some reason has been killing Deer with his 204 Ruger and 40 grain bullets for several years now - again no secret just well placed bullets and a complete transfer of all the bullets energy in the vital area of the Deer. Don't overlook the 55 grain offerings in the factory 223 Remington ammo - they work very well indeed! Hold into the wind VarmintGuy
Varmint Guy - Thanks for the input. I wasn't making any judgment on bullet weight - I was just listing the loads marketed by major ammo companies as being intended for deer. As far as I know, Remington doesn't market any of their .223 ammo for deer, but it is good to know that the Rem 55 gr PSP works in that application. I know others on the Campfire have remarked how their 55 grain handloaded Hornady .223 rounds have performed well on deer-sized game, so I don't doubt that some 55-grain bullets work for the task.
How does the 55-grain PSP hold up through shoulders, or is it a strictly through the ribs proposition?
