.338 R.U.M. fans

[RUMLUVER]

Looking for anyone that shoots a .338 R.U.M. and has any useful reloading data to share or just plain wants to chat about them. I am currently shooting one and I abosultely love and wished I hadn't waited so long to buy one!

[Evan03]

i have no intrest in anything with rum in it but id like to here about yours and how well it shoots, how fast. what weight bullets you use and the game you use it on.

im kinda into little calibers 25 6mms 3006 and 277s.

but theres nothing wrong with the RUM unless its in a drink.

lets here about yours and drive alittle more intrest to your topick

I have one and absolutely love mine. I have only used RL22 and never wanted to try anything else because that works so well out of mine.

The best load I have shot out of mine is with a Hornady 225gr SP Interlock. With 88.5 grains of RL22 My best groups are between .5 and .75 inches. (I had all of my group sizes and etc. on a spreadsheet, not backed up of course and lost the hard drive, so I have to go from memory and start over. At least I had my 'favorite' loads wrote down. )

Next best load was with 89 gr. of RL22 and a 210gr Scirocco.

I was not happy with the results I was getting from the Nosler 225gr Accubond or the the Sierra 215gr SP BT.

I might be able to improve on those last two with different loads, but am not sure if I want to try, I am getting such good results with the top two.

Are you loading for yours yet? If so let's hear how it is going.

[RUMLUVER]

I'm glad to see intrest in the .338 RUM! I'm currently finding great results with IMR 7828, RL22' and RL25. I'm shooting a 225gr Hornady INTLK at 3148.68fps average velocity with a standard deviation of 8.60. This load using 92.0gr of IMR 7828 cuts right under .5 most every time I shoot it. I also have a beautiful shooting load using a 250gr Hornady INTLK and 90.0gr of IMR 7828 that averages 2951fps with a SD od 12.72 this also produces .5 to .75in groups. This year for deer season I'm starting with a 210gr Barnes TSXBT and 96.0gr of RL22 this is an accurate load for me that produces a .75in groups with an average of 3395fps and SD of 14.31 wich produces 5374 ftlbs at the muzzel! This will be used for deer and the next will be a 210 Scirocco and 96.0gr of RL25 this load produces and average of 3236fps and a SD of 14.21 this load also leaves with 4883ftlbs at the muzzel. These are a few of my loads. I admitt this more than is required for deer and antalope this year but I can't help myself it is so accurate and damn fun to shoot. Hope this intresting enough!

[Evan03]

that is interesting.

thats heck of alot of powder but man are those 200 plus pills movn.

ummmmmmmm did you try tripple shocks just curious on your results if you did.



Evan

[RUMLUVER]

Yes I did try triple shocks and they work wonderfully. 210gr triple shock with 96gr of RL22 just right and 225gr triple shock with 96 gr of RL 25. The first travels at 3396 average velocity and the second at 3086 average velocity. Both with group at 3/4 to 1/2 in. when I'm doing my part. I have seen the performance of these newer Barnes bullets and have no complaints thus far. They are just flat ass devastating on game!

Well Evan, to pique your interest there is a wildcat out that is a 338 RUM necked down to 6.5MM (http://www.z-hat.com/Ultracat.htm).

I have a 300 RUM LSS. I had to order the thing seven times before they got the correct rifle in. It is my second favorite rifle, after the 25/06.

Is the 338 RUM based on the same case as the 300?

All the Remington Ultra Mags are based off a .404 Jeffery case. The case is as big around as .375 H&H case is at the belt. The .338 RUM is different from the rest because the case is shorter than the other RUM's. The .338 RUM has a standard case length of 2.760in and the rest are 2.850in. I asked Remington factory reps why this was and they told me that they got the best ballistics from the shortened case. So no the .338 RUM is not just a .300 RUM case necked up eventhow there is that wildcat available. Hope that aswered your question. I also have a .300 RUM and absolutely love to shoot it but not as much as my .338 RUM!

Thanks! I vaguely remembered reading that the UltraMags were based on the .404 Jeffery case, but was not sure. I also remember it was a big deal because it was not a belted case.

I do enjoy shooting it. I always got a laugh at the range I went to in Alaska. Everyone was a .338 fantatic and the .300 was a "pea shooter". I got condescending smiles when asked what I was shooting. Until the first shot. Pea shooter or not, there is a lot of powder in that case! Then everyone wanted a go.

The first time I took it to the range, I borrowed a range stand to hold my home made stand up (forgot my sandbags). It was made of 7/8" rebar and held my 1"x2" framed stand upright nicely. First sight-in shot I saw something move in my scope. It is a Vari-X III and I was a little concerned. The shot was high so I adjusted and shot again. Still high, so I adjusted again and shot, and saw something move in the scope! That was it, I was taking it back to the shop. Too much money to fool with. I go out to get my stand. As I am picking it up, I see two chuncks of 7/8" rebar on the ground. I had placed it in the center of my target, and those shots cut off a chunk of that rebar. I can't tell you how relieved I was. I took the pieces up to the range officer and offered to pay, but he laughed at my story and said it was payment enough.

Whoops.. got long winded.

Great story you are absolutly right their is nothing about that .300 RUM that says peashooter. The only advantage that you have with a .338 WIN MAG is the bullet diameter. With the bullet selection we have today I would not feel under gunned shooting at anything short of cape buffalo in Africa! The big reason I bought and shoot a .338 RUM is that I grew up reading some of my dads books and he was an Elmer Kieth fan and as we all know the .338 was the best all around caliber there was. So it was kind of a childhood intrest to buy one and around my town most people think you need a lanyard to shoot one! But after I shot it I was hooked. I absolutely love it and since then I havn't realy done much with my .300 RUM but it isn't going anyware either it still holds a place in my rifle case and always will.

[HPBTMTCH]

Yes, i don`t understand remington`s thinking here. The .338 edge is made by necking up 300 rum brass and is a bit faster, so i don`t get the short case. It`s interesting also, the 338 rum is the ballistic twin to the .338 lapua. Had a .338 rum in the LSS, till a buddy talked me out of the barrel, so i found a new 7 rum take-off. The .338 shot good, but never got below 3/4 of an inch. His rifle was a .300 win mag, and it shot horrible from the start. Now with the barrels swapped out, both shoot half or better, go figure that one. RUMLUVER, have you tryed the 250 and 300 grain sierra matchkings yet? The 300`s are impressive, they go through half inch of mild steel at a 1000 yards, and do a fair job on groundhogs. I can`t figure out if the bullet expands and does the damage, or if it`s absobing all that energy that makes him go poof, lol.

[RUMLUVER]

No I not had the chance yet but will soon. It should be intresting to see what happens!

Isn't that kind of like killing a fly with a sledgehammer?

RUMLUVER...
As stated in another thread, I'm currently working with a 338 Tomahawk I was attempting to get the 225 Accubonds to shoot and could to a point. Meaning I have shot some groups that would measure in the 2 or 3's but not consistantly. Personally, I think there was more bond and not enough accu put in the bullets I had. The first box of 50 I went through, it seemed that I could get 2 in one hole and one out with various loading of Retumbo. Switched to H1000 and the one out tighened up and gave a few tight groups as mentioned. Other boxes of 225's produced enough fluxuation that I went to another bullet. I went back to Retumbo, 250 SMK's, loaded 100.5 grains, ignited with a GM215M primer and the results were more consistant. I'm getting about a 5fps deviation with a velocity of 3120 out of my 32" Lilja barrel. That may not be the end of my testing yet but at this point I am satisfied with the performance of the gun and the 250 SMK's and somewhat less pleased with the 225 Accubonds for my set up. With some more tinkering, I may get the 225's to shoot but at this point I can't see taking a step back.

Have you tried the 225gr Hornady SST yet? I have used Hornady bullets in everything from my 22-250 to my .338 RUM and have had consistantly great results. I have personally shot groups the size of tylonal tablets using 129gr Interlocks and 140gr Interlocks in a .264WinMag and 6.5x55 mauser. Both of the rifles are factory model 700's! I shoot 180gr SST's and Iterlocks out of my .300 RUM and regularly turn out nickel size groups using H4350 and H4831. In my .338 RUM I shoot the 225gr Interlock with 92.0 grs of IMR 7828 and have an average velocity of 3148 with a SD of 8. This load also cranks out groups under 1/2 an inch. I also get great results with Swift Scirocco's and Barnes TSX's. I might try using some Sierrsa's this next summer but as of now I have naver reloaded them. I just have never realy reloaded anything for myself that I wouldn't hunt with. I have never seen first hand what a Gameking bullet has ever done on game with any kind of velocity. In another vein I am not a Nosler fan I have seen first hand what their bullets do to game Ballistic Tips & Partitions and have never bought or reloaded their bullets and don't plan to. I don't hold any high hopes for the Accubond either. Just my opinion thats all many have disagreed with me but thats OK.
