After much research, study and practice- I've finished my 1st batch of 300 Savage re-reloads...But...
Primers look funny after shooting
The three on the left are factory Remington Core-Lokt 150 gn. rounds
The two on the right are my reloads
All shot fron 1930's "G" model 99 - all shot were very accurate...
Used Reloader-15 with Rx Used - all power charges were measured one at a time....
"Hornady's 8th edition lists Reloader 15 with a 150 grain SST in the 300 Savage
with a starting charge of 37.2 gr. @2300 FPS to a maximum load of 43.1 grains @ 2700 FPS."
Bullet 150gn Nosler Ballstic Tip
Reloader 15 - 37.5 gn
Trim length: 1.860
Is this an issue with primer - this is my first batch to reloading !! so go easy on me...
Is 37.5 gn of Reloader 15 too hot....
