I've had my LAR since it was new and hunted with it since 1987. Factory rounds weren't sufficient for hunting so I started reloading. No other brass holds up better to the high pressure loads like these from starline. Easily reloaded ten times. Great stuff !! I will replace the rest of my reloading brass for all my calibers with Starline.

I own 5 Lar Grizzly pistols , all chambered for .45 WM. Thanks to these great Starline cases I can shoot those magnificent guns. philimandias - Belgium

45win-mag. I have the grizzly-6inch/7shot mag mark1. this brass is the only stuff that will not split.I have had this wepon since 1998 and I shot 230grFMJRN at 1350 FPS that I reload for my-self and know after 10 times. This brass is still OK.

I purchased Starline 45 Win Mag Brass from a dealer to try out reloading for a 30 M1 Carbine Conversion to 45 Win Mag and found the brass very well made and to SAAMI dimension specs. I am loading to the 30 Carbine Overall length for my tryals and will report further after trips to the Range.
