338 Rum

Have a custom edge and was kicking around a light weight carry 338.. Have a chance to get a new 700 ss 338 Rum 26" barrel. First i would install a break but wondering of opening it up to a edge how it would perform with that light factory barrel. Second thing would be let it alone and work witht he standard 338 rum. It would be a lr and elk rifle thinking the 300 smk would be to much what would be another choice of bullet for this purpose?

Re: 338 Rum

I have that exact rifle and to 1000 yards the 225 grain cutting edge bullet .64 bc does very well at 3150-3200 fps. Before that I was shooting the 225 AB in it. You will not gain anything by rechambering to the 338-300 RUM. Same thing/same performance. Both shoot the same numbers and loads.

Re: 338 Rum

+1 on what LTLR said. The 225s are pleasant to shoot and can still reach 1000 easily enough, especially if you go with the CE's. I shoot 300 SMK's in my sporterwieght, it deffinatley under 10lbs but im not exactly sure of the weight. Its the normal Rem XCR.

Re: 338 Rum

Angus, What powder you shooting in your sporterweight? With the old H1000 I could hit near 2800 fps out of my 26" barrel with the 300 smk but the accuracy was at around 2735 fps with 91 grains. I get good brass life with the lighter load. I use it for backpack hunting and under 1000 yards. Last summer I tested the 225 grain D 62 CE bullet .64 bc and the accuracy was best in the 3150-3200 fps range with much less recoil. When I ran the numbers for the range I use this gun the 225 with 400 extra fps looked pretty good. With a 225 grain bullet there is energy to spare so that is not a concern.

Re: 338 Rum

Appreciate the info, what 225 bullet are speaking about? Do you need a Wyatt box for it? What vel. should i except out of a 26" factory rum.

Re: 338 Rum

I use 92 grains Retumbo with the SMK for right around the 2800 fps mark. I pushed it to 94 for 2850 and still had good accuracy but I wasnt getting good brass life and the pressure was on the high side.

Actually with this rifle I have found loads with every bullet form 210 TTSX's to the 300 SMK's that will go into 3\4. not bad for a factory rig. The SMK's better yet.

*edit* that velocity has only been chronoed form my "shooters" chrono. It does match up to my drops though.

Re: 338 Rum

I currently use the 3000 smk out of my edge but figured they wouldnt be as effective out of the rum.
