As we get older, sometimes we get "set in our ways" - I killed many white tail and mule deer with 308 Win using 165 grain Speer HotCor and RL-15 powder - worked fine many dozen times - I have enough on hand for the rest of my life - no reason that I know of to change anything there. That was a change from 165 grain Sierra SPBT - that bullet came apart once on me - I usually only get to take a few deers a year - so I switched to Speer HotCor, and have not experienced a failure that I attribute to that bullet not doing its job. And 7x57 - I got many dozen deer with 150 grain Partition and RL-19 powder - again, I stocked up - not likely to change much, until I get to try different rifles and they want something different. I found out that life is too short to chase after every "latest" and "greatest" improvement or gizmo - I found what works, a long time ago, and got enough on hand - so I do not care about "modern" prices, or "modern" ideas of what is "best" - I know what has been working for me - I chose to stay there.
