Question for 300RUM Owners

So here is my question for anyone having any knowledge or owns one.
What brand and weight of bullets do you use???
What powder do you use & how many grains do you use???

Re: Question for 300RUM Owners

Hi, my first post here. I shoot a Remy 700 XCR and I'm shooting 100.5 gr. Retumbo with a 180gr. Barnes ttsx bullet. According to my chronograph it's averaging 3325fps. Of course it's only a 26" stock barrel, my 100 yrd. benchrest groups for 3 shots average .68". I've only had the gun for a year but so far I love it! Going to bump up to 200gr. bullet this spring and step out a bit with it 500-800 yrds, and pay my dues and put in some serious time practicing. Hope you get her dialed in, mine shot ok at first but I went ahead and pillar glass beaded the action, floated the barrel, and tuned the trigger to 3.5 lbs. Made a difference for MY gun, this is a hunting rifle and am quite happy with the results so far. Good luck.

Re: Question for 300RUM Owners

Before I even shot the gun I had a gunsmith work it over, bed it and float the barrel and work the trigger up. My wife has a Remington 300SAUM and it was very easy to get sighted in. But her gun only seems to like the 150gr accubonds. For all the money I have spent on berger bullets I really hope its not that my gun does not like berger bullets.

Re: Question for 300RUM Owners

I would have shot it before putting money into it. I have a Sendero II in 300 RUM, and it's a sub 1/2" grouper box stock.

My light recoil load for friends (and the wife) is 85gr of RL22 behind a 180gr Hornady Interlock, and it shoots 0.4" groups. Velocity is just a scoach under 3100, which is sad for the RUM, but like I said it's a light load. Just something for you to try. I'm still working on my top end loads for the 200gr Gamekings and 210 Bergers.

Re: Question for 300RUM Owners

Did you buy your RUM new ? Do you know how many rounds you have down the tube? I shoot a 300 sendero I bought mine new and when I had the factory barrel on it I shot 155 AMAX'S it loved them If it want shoot AMAXS good or better than what your shooting now then something is goign on . my gun didn't like the 168's but loved the 155 's I would feel confident to say that it should shoot the AMAX very well . Now I have a custom barrel and it has taken a little work to get the bergers to shoot but they shoot ! I'm not the greatest when it comes to hand loading but I seat my bullets to were it will barely fit the Mag. try that if you havent already oh and try some retumbo some one once told me that retumbo is your friend in the RUM boy was they right! Good luck.

Re: Question for 300RUM Owners

Yes I bought the gun brand new. I have probably only shot 75 rounds through it, so the barrel is probably not even broke in yet. Today I loaded up some Scirrocco's and loaded up some more 185's and 190's, I did seat them closer to the lands, they will still fit in the magazine. But it could be that my gun won't shoot berger's. If these don't shoot then I will pick up a box of accubonds and try those, if they won't shoot then I am heading back to the gunsmith and see if he can figure it out.
Am pretty much using only Retumbo for the moment, I have a 8lb jug of Ramshot Magnum, hope to get to use it.
