Nebraska402 Report post Posted May 13, 2020 Hey I'm looking for some load data on the above round for a 300 rum using retumbo. I'm hoping someone has a berger book and could take a pic of the page for that? Thanks. Marshall Share this post Link to post Share on other sites
SO I HUNT Report post Posted May 14, 2020 I use them in a Christensen Arms Ridgeline 300 rum loaded@ 85.6 of retumbo 3.65 overall length and they shoot lights out! Brass norma and 215 primers. you can do a search and on google and find all kinds of information too.. Share this post Link to post Share on other sites
lancetkenyon Report post Posted May 14, 2020 I am not at home, but I have loaded that combo before. Start way lower, but I got up over 90.0 with the combo. Safe in THAT gun. Think about the 230 too. I push them at 3113 in my 28" .300RUM over Retumbo. 1 Share this post Link to post Share on other sites

Loads for Retumbo are not listed. I assume the reason is that Berger considers it a very slow option for the 210 or 230g bullets in the 300RUM. I'd go to the Hodgdon powder web site for load info. A tip when trying any new load. Find your bullet touch on the rifling and always start your load at a minimum of ten thousands off the rifling. Hornady makes a bullet seating guage and there are others that will render great results when looking for a proper seating depth. It is very dangerous to try any load with the bullet jammed into the rifling! A safe load can turn into a very unsafe load with the bullet jammed!! Share this post Link to post Share on other sites
