338 rum

New sub. to this site but i read it all the time. I just had a new 338 rum built on a savage 110 action with a 30" barrel. I am loading 93 grains of retumbo with 300 grain bergers with no pressure signs. Can anyone tell me what my vol. might be. thanks.

I would run it through a Chronograph or your just simply going to be guessing.

I'g guessing he does not have one. I would invest in one no one can tell you for sure.

Re: 338 rum

I run a 338 LM with that same load and am at 2820 fps. I also have a 338 RUM and shoot the 250 SMK with 97 gens of H-1000. It's at 3021 fps. I could not get the 300 SMK to shoot well in this rifle. The TTSX 225 Barns shoot well with Retumbo in my rifle.

Hey Goob! (funny thats my bros nick name) I would bet your pushing 2800 fps. Its hard to tell without a chrono or a drop. the average speed for this load in a 26" barrel is 2725. ad 20 fps per inch of barrel you end up with 2805(low ballish). This load should push your super sonic to around 2k

Re: 338 rum

I want to get a chronograph. but i know nothing about them can anyone reccomend a brand. Also 95 grains makes the primer dents feel a little raised and rough is this signs of pressure?

Re: 338 rum

When your primer raises like that its a pressure sign. I would say that you would do well not to go above your 93 grains.

I have a 26" barrell on my .338 RUM and with 94 grains Retumbo Im getting right around the 2815-2820 at my elevation. you should be running a little faster with you 30" even though a grain less charge.

I cant stress it enough, a chronogragh is seriously as important to long range shooting as a scope with turrets or hold-over reticle... you cant be effective at it without one (even though I've seen some old timers do some crazy stuff with ol' kentucky windage, still not great). I tried for a long time estimating my velocity. when I broke down and bought a chrony my game got 10x better overnight.

*EDIT* I have a "shooter" chrony, cheap but it works.
