Thanks for your help in advance…paul.

Your C: Not a proof unless a “tinned” stannic-stained case, The Remington HPT of that era used nickel plated cases.

Remington ball rounds of that date give the appearance of a red base, but it is just primer annulus sealant, not effectively applied.

Hi Paul,

“A” is a Black Hills 77 Gr Match HP Moly Coated (bullet made by Sierra).
“B” ia a Speer 42 Gr Frangigle RHT (Lawman RHT line; bullet made by SinterFire, Inc).
“E” is a Federal 62 Gr Bonded SP (LE Tactical Bonded line).
“G” No. 1 is a Simunition Greenshield Frangible by SNC Industrial Technologies Inc., and No. 2 is a later version of the same by SNC Technologies Inc. Nominal weigth is listed as 2.3 g (35.49 gr) and/or 36 gr (2.33 g).

Regards,

Fede

„F“ is a short range.

With the same kind of bullet also available in 7,62x51 and .50 BMG.
in ball and Tracer.

Hi Dutch… I thought it was short range, but my bullet weights 42gr when it should weight 47gr. For such a light bullet, one weighting 5gr lighter would reduce it range alot I would have thought. So need to find one more the same weight as mine, or is mine an experimental as it came from a collection with lots of experimentals and no paper notes!

Your Speer, the “NT” is non toxic or a lead free bullet.

many thanks…paul

Paul,

Cartridge ‘C’ with headstamp RA 54 is an XM196 tracer round (LOT RA 223-131).
I have the same, also with red paint-remains in the lettering.

Photobucket is back online, so here are the pictures…
