I re-barrel the Marlin 336's for 445 SM and this brass is perfect! This cartridge really sings from a rifle and this brass is robust enough to take heavy crimps, lever actions, and multiple reloading with 265 / 300 grain bullets. Thank you Starline

Was given a MGM 15" Encore barrel in 445 Super Mag for Christmas. I ordered some Starline brass and was extremely impressed by the consistency. I loaded up 50 rounds with a healthy load of 296 and the 250 Sierra... My shots were touching at 50 yards.

I have a 445 Super Mag from Dan Wesson. I have used the 445 Super brass since 2001. No problems or issues whatsoever; this brass is designed to sustain much greater pressure than the 44 Mag brass (445 goes about 45 to 50 thousand PSI). The brass is thicker to be able to take the increase pressure of the 445 Super since this caliber cannot be loaded light. It is durable and worth the prices. Some of my cases have taken five firings without any problems. It is the only brand available and it could be much more expensive but it is fairly priced and because of the quality, a good investment.

This brass has functioned well with no sticking cases at this point. It is nice to be able to shoot my DW .445 Supermage again with NO brass sticking issues. Thank you for saving this great cartridge!

Excellent brass. Have reloaded some cases as many as 10 times without any problems. Would highly recommend anyone reloading .445 Super Mag to use this brass.

Originally I had some brass stamped "Gates". I had many problems with that brass. Then I tried the Starline Brass. I've loaded the brass approximately 10 times now without any problems whatsoever. I wished I would have tried this brass sooner.
