300 RUM handloading question

[BULLBLASTER]

i know a few on here have the same rifle as me and i am hoping they will chime in. i have a sendero in 300 RUM and have a couple reloading questions. i am loading berger 210 grain bullets over retumbo. my gun shoots real well at 90 grains and 2830 fps. i read of people pushing these bullets over 3000. at 91 grains, where the firing pin hits the primer pops back out, showing pressure. 90 grains doesnt do this. also i bought a box of factory 180 sciroccos that dont shoot real well, and these are showing more pressure signs (primer popped back out and extractor mark on teh case.

i would like to get more velocity with the bergers, or at least someone to tell me that 2830 is plenty. anyone have any insight?
thanks

BULLBLASTER,

I have the 700 REM in 300 RUM. I shoot the 180 scirocco's and thats it, they shoot very well out of my gun and I never have and signs of pressure.. Sorry I cna't help ya with more than that...

I have taken atleast 4 elk and 8 deer with this combo. Never had one take another step......

2830 seems real scaled back to me. I used to load for a pard, the exact gun, 180 siroccos @3460 average. Had one go over 3500! After seeing the handy work of a 210 berger in a 300 RUM first hand this hunting season, I wouldn't shoot em, ever! If you wanna go big, try the 208 A-maxs, or make damn sure you hit bone like the BOTW boys, ie; high shoulder shot... Later

what was wrong with the berger?
i always take high shoulder shots with my rifle.
this gun consistently shoots 1/2" groups with the 210 bergers and retumbo.

They don't expand. Saw a pard shoot a 80lb speed goat at 600 yards, I called a miss, cause I saw dust fly up behind him, no reaction whatsoever from the goat. It ran about 100 yards give or take and laid down. After watching it for a while, it laid down dead. Gutted it out, looked like somebody poked a whole through it with re-bar, pinky hole in, pinky hole out.  That may be fine in open country, but over here, thats a lost animal. He also had trouble on a bull, and muley buck last year. I've killed enough critters I know what I like. I like to hear a loud shhhwwwaaaack when the boolit hits, and I like the engine compartment to look like raspberry soup. You won't get that with said combo. If you like high shoulder shots, they'll prolly work for ya. Shoot 96 grains of RL 25 with a 180 sirocco and see whatcha think! grin... Later

If it shoots that good I would not play with it. A few more fps wil not make to big of diffrence unless you are shooting very long range.

The pard is shooting 200 accubonds outta a win mag @ 3080. That RUM should be rippin em out there a hellava lot faster than 2860. I disagree, squeeze every last fps out of it, with good accuracy, Barrels are cheap.

Thats the thing If the groups don't stay small and there are pressure signs why mess with it

[257 Wby Mag]

Because they make more powders than Retumbo?  I would say he's shooting long range, given the boolit, and chambering.. Lotsa other slow powders, give em a try, don't get stuck on one. Later

[carpsniperg2]

150fps more at 500 yards with that 210g would only be about 4-5" less drop. With it shooting 1/2 which is very good for a mag, I would take that and stick with it myself. Most people should not shoot past 500 yards in my mind. I spend 1,000's in ammo and countless hours on the range to do it

I also know that some loads use the h50bmg you might check that out, one of the slower burning powders out there.

[257 Wby Mag]

Good then. Thats why I shoot a 257, not a 25/06. Or my 300 Roy, not a 300 Win Mag. My theory, if your gonna shoot a magnum, shoot a magnum, why not load it to its full potential? Maybe he should be shootin a 06?

[carpsniperg2]

  Just a couple extra clicks on the scope

Oh and I will put a 25-06 against that 257 any day

I think he said he is already shooting 90g of retumbo which is 1grain more then that load you listed and he is 2830fps and that load data from someone on the net says that with 1g less it's 100fps fatser Unless barrel length is diffrent.
