When F.L. Resized, with my Hornady Die, the cases measured 1.293" in length.
They have been trimmed to 1.290" length, with a RCBS hand-crank trimmer, and de-burred.
Case mouths have been slightly flared to accept a bullet base.
I was wrong on the brand of 110 grain RN jacketed projectiles, with exposed nose, that I photographed. They were made by Sierra, (#2100).
(I have several boxes of Hornady 100 grain projectiles, with 1/2 jackets, and got confused).
Attached photo shows trimmed & flared Armscor resized cases, (trimmed length 1.290").
Lightly inserted Bullets (L to R) are ARMSCOR 110 grain, Sierra 110 grain exposed RN, and 1/2 jacket - 100 grain Hornady.
