The old Remington 240 gr. jacketed hollow point is a mainstay in 44 Magnum handgun loads for whitetail. I have shot a number of whitetails and hogs with this bullet in both pistols and my Ruger rifles. Even though many may consider it old tech, it still does the job.
Deer are very thin skinned and penetration is easy, I have used the Remington 240 gr JHP with success. You are correct, the bullet is "old tech", but deer don't need high tech "boutique bullets" to bring one down. They are not as tough as elk and bear.
