Ammunition for the 300 SAUM isn’t exactly plentiful, so I was very pleased that it is available here. I have found several hunting bullets that shoot very well in my gun – at, or under, 1 MOA. My favorites are the 180 gr BarnesTipped TSX and the 185 gr Berger VLD Hunter. Great service and a fantastic product here at Hendershot’s. Mark C.

Great service!! Very surprised with how quick the order arrived after searching for many months to find this ammo! And the ballistics charts should prove helpful on longer shots. So far, holding about an inch pattern at 100yds in my REM. BDL. Thank you Hendershots!

Just received my order from Hendershot today; an early Christmas present since .300 Remington SAUM’s are impossible to find today. Online ordering was a breeze and I was impressed with the fast turn around. Can’t wait to get my rifle on a bench and start testing these rounds. Will definitely order some Hendershot again in the future. Thank you!
