What are yall guys velocities out of a 300 RUM 26 in barrel with 210 gr berger and retumbo power?
My 300 rum likes the 210 vlds going 2985 to 3000 fps. That is with 90grs, i did try it with up to 92grs and it went 3050 to 3075 but accuracy went way down.
What was the accuracy like at 92 grains?
The accuracy wasn't horrible, it was approx 1.25 at 100yds. The 90grs I sacrificed for accuracy. It puts 5 shots just over a 1/2 inch. If I would have messed with the seating depth it probably wouldve tighted up.
I load my RUM with 93.5 grains of Retumbo behind a 210 seated .015 off the lands. Velocity is approximately 3180 FPS and has proven to hold nearly 1/2 MOA out to 1,000 when I'm doing everything right.
hey elk how are you getting those bergers to your lans arns the rifling 4.10 out in my 7mm rum i cant get anywhere near the rifling
I have a custom barrel on my rifle so the chambering gives me 3.035" to the ogive and approximately 3.7" COAL.
My buddy is getting 3130fps with 93.4grs of Retumbo, 215m and Rem. brass 210VLD seated to fit in the magazine of his 26" factory tubed Rem. 700 XCR. The last time we shot he put 2 at 1" apart at 440yds. First 2 cold bore. Gotta like that!

Accuracy will vary from rifle to rifle. Mine shot that load in about the .5-.6 MOA range.
I went with another bullet.
