Ok so it look like this retailer has been holding onto that Winchester ammo for 13 years which explains the bargain prices.1. 2010 (loaded with 500Gr Nosler Partitions & 500Gr Nosler monolithic solids at 2100fps).
2. Barnes does 2240fps with 450Gr TSX all-copper hollow points. You mentioned the Federal with 400Gr bullets. There is nothing faster.
3. Hendershots Custom ammunition offers 300Gr & 350Gr loading options with the Barnes TSX bullet. And 400Gr loading options with the Swift A Frame bullet. You could also persuade them to load you up some ammunition on special request with Speer Jacketed Hollow Point, Hot-Cor & Jacketed Soft Point bullets in 300Gr, 350Gr & 400Gr weights respectively.
Any concerns with shooting 13 year old DG ammo from a safety point? I'm guessing that's not actually that old but I don't typically hold onto ammo longer than 2-3 years.
From a performance perspective I'm guessing this "new" Winchester 458 ammo won't be plagued with any of the initial powder clumping or velocity concerns.
