My stepson gets MOA groups with his. It's no fun to shoot, kicks like a mule, but i've shot 4 inch groups at 400 yards with it. Barnes 180s TTSX with 100 grains of Retumbo. We neck size only using a bushing die.

Mine shot like that before I developed Retumbo Load for it. I'll have to check the load data for you. My load data is for a 180 accubond although it shot extremely well with a 200 gr nosler partition and was more predictiable. Also, for some reason mine only shoots accurately with new brass. Once fired brass causes erratic bullet behavior in my rifle thus I only reload new brass. I haven't had to reload since 2007 but I do remember that mine does not like a long bullet. Stick with the factory oal if your not already. How deep are you seating your bullet?

Re: Rem 700 300RUM poor accuracy

It's really important, for the sake of accuracy in the RUM, that as your finger lights the trigger that you keep both eyes open and your cheek welded to the stock. Kidding but also a serious point.

It sounds like you could benefit from a new barrel. If Remington sent you test targets after doing nothing (recrown) and said it was GTG and it was still producing 3-4" rebarrel it or sell it and start over.

I have heard that a lot of folks have had best luck with shorter OAL's using shorter bullets.

I have a heavy barreled 28"Krieger and shoot 190 VLDs touching the lands, 98g's of Retumbo with excellent results. My last trip produced 2.5" at 500yds.

It always suck when you pay good money for poor results. Hope it works out for you.

Re: Rem 700 300RUM poor accuracy

if the barrel is getting hot slow down, can you shoot better groups with other guns? try putting it on a lead slead. my 300 RUM will shoot sub moa with every thing i try retumbo with 200gr accubonds or 210 smk's all the way down to 150gr ballistic tips. at first it didn't shoot very good, then I stoped flinching;). did you break your barrel in properly?
