Tams,
I take exception to your positions rarely, and then only with trepidation. However:
1) My larder has a few hundred rounds of 200 grain, Georgia Arms, .45 Colt, Gold Dots that provide 1100 FPS velocities ten feet from the muzzle. Recognizing that is a relatively mild .45 Colt loading, it still has plenty of potency (IMHO) for personal defense.
2) Re Silvertips, I agree it is an older design, it sometimes sheds material, doesn’t always fully expand, and can separate. However, I believe it is still a reasonable defensive projectile -- as are its chronological peers from Remington, Federal, etc. I would agree they are not optimal, but you and I still carry 158 grain LSWCHPs, which remain effective despite their “seniority”.
My belief is new is sometimes -- perhaps often -- better, but that does not mean older is inadequate (perhaps I feel this way since, in another 18 months, I’ll be 60; therefore, this philosophy applies to a good deal more than cartridges).
Merry Christmas and many thanks for your continuing education -- Roy
