Due to the packaging and shipping process, case necks are often slightly dinged or bent and need to be rounded up and sized to give proper neck tension. New and/or fired cases must be full-length resized or have the expander ball of the sizing die run through the case neck prior to loading.

Great brass, will be used in a TC Contender.
Glad that Graf stocks this product.

Great brass. Just bought a TC Contender barrel in 45 Win Mag and appreciate that Starline carries this caliber. High quality. Plan on loading soon. Will buy more later.

This brass is nearly perfect. All 100 cases are right at the proper Trim to length. All primer pockets were free of internal burrs and the proper depth for seating WLP primers. All I did was expand the case mouth slightly and loaded them all. Out of the 100 cases, only one had a slight dent on it, but was fine for loading. I have had the similar excellence with the 45acp cases.
If Starline produces the cases I need, I always use Starline brass.

Very good quality brass and great price.

Hard to find, excellent quality as always with Starline

45 Winchester Magnum is a special application cartridge. I have property in settled areas that have deer and other big game. I build custom rifles in 45 Win Mag, which are loaded with a custom 335 grain cast bullet at 1050 fps. This load will break both shoulders of a deer or hog without rattling the neighbor windows at 6 AM. No worry that the animal will run off and bleed out on someone's driveway. No suppressor necessary with 24 inch barrel. Too bad no commercial repeater is offered. Best cartridge i have found for this application.

Excellent quality brass with a great price to boot! Definitely keeps the cost of reloading this caliber down compared to buying ammo.
