Range Report Best Bullet for 300 RUM?

[Long Range 338]

I've got a Rem 700 Sendero in 300 RUM. I've tried a few different bullets with the heaviest being the Hornady 208gr. Accuracy has been "meh" around an inch with nothing being outstanding or terrible. What have you guys had good success with in factory barrels?

I just got offered a 700 in the 300rum with only half a box of ammo through it. Original owner said it was too much. So I picked it up. I got some factory ammo for cheap from another guy to start collecting brass. So far I tried the factory 150gr accutip, it was garbage. Next I tried the 180gr core lokt ultra bonded psp, that also shot like garbage. Next was the 200gr A-frame. Those shoot amazing!! At 220 yards I got a 3 shot group under 1.5” I marked my target and shot 3 more with the magnetto speed. Again 3 shots in around the 1.5” group. Super happy with the ammo.

It’s been quite some time since I have messed with my 300rum, probably haven’t touched it in 3 years. My 300 rum is also the sendero. When I was shooting it I was using the 208 a-Max with retumbo and was getting 3/4” or better groups. Not outstanding but decent and likely could have been smaller but recoil and poor recoil management had a part to play. I cannot remember what speeds I was pushing the 208’s at but likely it was not at the top end of the pressure range.

Not in an UM but in 300wm the 200 accubond is a great bullet and easy going to tune.
Not the highest BC but it's easy to find a load with them and they perform very well on thick hide and heavy bone.

I've spent a lot of time behind a .300 RUM, and the 220 grain SMK was my favorite. On top of a healthy charge of Retumbo. When I am developing a load i go straight to the SMK.

When my rem 700 Long Range 300RUM had it's factory barrel the best by far was 200gr Accubonds and Reloder 33. Right at 3200.
The new barrel is running 230gr OTM and N570 at 3120 fps.

215 Hybrids in Rem cases with Retumbo. My factory Sendero shoots them really good out to 1500.
