I have two 300 RUMs that I use for hunting and target. In fact, I am going out for cow elk today and tomorrow (in the Uinta mountains of Utah). Both actions are Remington 700. One is a stock Remington action and the other Defiance. I use Manners stocks on both rifles (same stock) and Jewel triggers. I have a Proof research barrel on the Defiance action and Krieger barrel on the stock action (both barrels are 29" and I shoot both rifles suppressed). Both barrels have a 1:10 twist which works well at the altitudes I shoot, however, when it is time to rebarrel, I will use a faster twist. Both rifles group well but the Defiance/Proof rifle is slightly better. I attribute the improved accuracy to the stiffness of the Defiance action (that action is awesome). In addition, I would rather hunt with the Defiance/Proof Research barrel for obvious reasons (it is a lighter rifle).
I run the same load in each rifle. My load is 230 gr Berger Target Hybrid with 88 grains of Retumbo. I like the Target Hybrid because it has a Hybrid ogive so it isn't as critical to seat the bullets so the ogive's are super close to the lands. The 230 grain bullets are so long that I need to seat them so they will fit in my magazines. To fit my magazines, I seat the bullets with the Ogive more than 0.050" from the lands. I run Norma brass in the Proof Research barrel and Nosler in the Krieger (I need to use different brass in each rifle to avoid mixing up the brass). I use Federal 215 GMM primers. I get 3005 fps from the Proof barrel and 2998 fps from the Krieger barrel.
I've killed a lot of animals with Berger Target Hybrids and Berger Elite Hunters (I use those in my daughter's 270 WSMs). I don't not see a difference in terminal performance between either the Target Hybrids or Elite Hunters. I use the 300 RUM rifles for Elk, Mule Deer and Antelope. My longest kills using the 230 grain Target Hybrids were; Elk 850 yards, Mule Deer 500 +/- yards and Antelope (a doe) 900 yards. In all cases, the shots were well placed and animals died quickly.
I also use the 300 RUM rifles to shoot steel (we also shoot 1 gallon milk jugs at that distance). I also have two 338 LM's and use 300 grain Bergers (MV of those rifles is around 2780 fps). At one mile targets, I have to dial in an additional 1.5 to 2 meters of drop on my 338 LMs than I do on my 300 RUMs. Said another way, the 230 grain bullets have a high enough BC relative to the 300 grain 338 Bergers that the 230 grain 30 cal bullets out perform the 300 grain 338 bullets.
I cannot recommend the 230 grain 30 cal Target Hybrid bullet enough in the 300 RUM for both hunting and target. I think the 300 RUM is the best chambering in 30 Cal for long range hunting (for Elk, Mule Deer or Antelope). I absolutely love my Defiance/Proof Research rifle.
I hope this helps.
I just wanted to add, that I have tried H1000 and 7977 in the 300 RUM with the 230 gr Target Hybrid bullets. Those powders worked well but had lower MV's than the Retumbo. I use the 7977 in my 2 270 WSMs (I use a 170 grain bullet in those rifles).
