HI John & Glenn
Speer made a number of rounds during the yellow plastic box era. Perhaps sometime during the era of George F. Fairchild’s import business with DWM ca 1964, which failed, but I think most of that was in white paper boxes & Fairchild was not an employee of Speer at that time. Later, ca 1967, Ray Speer partnered with DWM. So although Ken doesn’t state your 8x57 from a plastic box could perhaps be from that time.
Reading further he also notes “The centerfire ammunition brand was changed to CCI in 1978. After the introduction of Blazer aluminum cased ammunition in 1981, the CCI brand and head- stamp were designated for that alternate shellcase material, low-cost, high value ammunition while the brass cased ‘premium’ ammunition reverted back to the SPEER brand.”
So, sorry nothing definitive, but I’d think your 8x57 is from the early 1980’s.
Also from Ken Alexanders book, The Brothers Speer, their Companies and Products (1942 – 1975), the Weatherby 7mm, 257, 270 & 300 case types were ca, early 1950’s.
So Glenn, since you pulled the bullet, does your .270 Newton have a reflector base? As I think all 270’s 450 Watts were sold as just “cases” not cartridges your loading mark on the primer is, in my mind, just fine as a keeper. Might be better if never loaded, & just a new case, but you takes-em as you get-em.
A Nitrex 7mm Rem. Mag. box has Blount Inc. of Lewiston ID on the back as maker.
Ray I’m envious, two fingers, dang!
PS my next sale (I’m working on it so don’t ask when, cuz I don’t know when) will feature Gene’s collection of Wildcats and other goodies from his collection, so probably in there somewhere. He had a GREAT bunch of wildcats, took me over a week to sort & lot up. A .270 Newton would very likely not be in the Lab as it isn’t military.
