What barrel length and brand would you guys go with for the above calibers?

Function:
This rifle will be used for long range hunting and I would like to keep it under 10 lbs for just the rifle.
 
Re: Considering 300RUM or 338 Edge hunting builds

for sure the edge go 28" medium palma fluted in 10 twist. I got mine from benchmark barrels and it shoots 1/2 moa and better when I do my part. their info is at the bottom of my signature. I don't work their or get any kickbacks I just love their barrels and they are good people to deal with.
 
Re: Considering 300RUM or 338 Edge hunting builds

A little confused here. Is there that big of an accuracy difference between a Light and medium Palma?
 
Re: Considering 300RUM or 338 Edge hunting builds

With as many configurations as he has probably done by now, I think giving Shawn Carlock a call would be worth your while in figuring this all out.

Not knowing where you are in ID since you didn't list it in your profile, Shawn may well be right down the road from you.
 
Re: Considering 300RUM or 338 Edge hunting builds

i dont think you need the 28-32" tubes for what you desire. the one i just finished is 27" and makes 2875 with the 300mk and retumbo. i would think 26" would be fine. i too LOVE benchmark barrels. they treat me very well.

Re: Considering 300RUM or 338 Edge hunting builds

I agree I should give Carlock a call. I really want to keep this thing as light as possible due to carrying it for miles each day while hunting. Then again, I would be more than happy to lug a little heavier rifle if it guaranteed me more accuracy for that crucial first shot. Is the medium Palma worth it for the extra carry weight if you are hiking a lot?
 
Re: Considering 300RUM or 338 Edge hunting builds

i have two medium palma blanks ready to build on as we speak. they are pretty close to a sendero contour if that is what you are looking for.

Re: Considering 300RUM or 338 Edge hunting builds

AT SOME POINT A RIFLE CAN GET TO LIGHT FOR LONG RANGE ACCURACY AND SHOOTING THOSE 300GR SMK NEEDS A LITTLE WEIGHT TO HANDLE RECOIL. THE SENDERO CONTOUR SEEMS POPULAR FOR THESE BUILDS,BUT WITH NIGHTFORCE OPTICS THEY END UP AT 13 1/2 POUNDS. I WOULD GO WITH A MODIFIED PALMA CONTOUR, SAY .040 OVER LIGHT PALMA,0.0790 AT MUZZLE. SHOULD PUT YOU IN THE 12 1/2 POUND RANGE.

My Edge is 19lbs loaded up,with a 28" Fluted #7 Mike Rock.

Scott,
I would like to have that gun my friend! Beautiful! It is a little heavy for all day packing, but I bet I could just set up in elk camp, take out the game and leave it in the trailer till I get done packing it out

Re: Considering 300RUM or 338 Edge hunting builds

What bullet do you want to shoot and how fast? Do you reload?
I am not trying to stir the pot, but just want to make sure that you aren't putting the cart in front of the horse so to speak. Between the two cartriges you are talking about, I don't really think you are gaining much either way in terms of terminal performance in a hunting role. Without getting into the ethics discussion regarding hunting at ELR, I really can't think of a hunting scenerio where the difference between the two chamberings would make any difference what so ever. There are a lot of nice 30 cal. hunting bullets available that will be terminally effective well beyond any distance that I would shoot at an animal.

So if you don't reload, the answer is pretty obvious, 300 RUM.

If you do reload, then go with what you want, but of the two options I would still chose the 300 RUM if the central focus of the rifle was for hunting.(Just because in a pinch I could find ammo for it.)

Actually, for hunting, I would go with a 20-22 inch 300wsm or something in 7mm but that is a different discussion all together.
 
Re: Considering 300RUM or 338 Edge hunting builds

Norwiscutter,
Yes I do reload. If I go for the 300rum, I would like to lob 210gr VLDs. Velocity to me doesnt matter so much as consistency of POI. I have a 300wsm, but it is a Browning A-bolt that I got some work done on. It shoots nice, but I want something that is built to reach out and touch things. It has a twig of a barrel and I don't think that helps with the accuracy. I am thinking of selling it and putting all my eggs in one basket with a nice custom rifle. I agree, the 300rum is more than enough for anything in North America.
 
Re: Considering 300RUM or 338 Edge hunting builds

Well, I agree with getting rid of the Browning, but am not real sure how to take the wsm can't reach out and touch things comment. I guess it is all a matter of perspective. Now I just finished a heavy rifle build in 30 cal. for the sole purpose of shooting the 208 amax. and 240 matchkings at distance. I went with the 300 Roy simply because I had the dies and the brass for it. 28 inch m24 conture tube manners stock, etc, etc. But here is the thing, it is a fricking boat anchor, and likely won't see to much hunting use. Now the real advantange of say a 300wsm is that it provides efficent powder utilyzation in a shorter barrel, which of course translates to being lighter. You mentioned a desire for consistant POI over velocity, which should lead you more in the direction of a shorter, heavier contured barrel. I won't delve into this much more, as there are some great threads on this in both the rifles section and the extreme long range section here on short barreled rifles in 338 lapua, 300wm, etc. so that ground is pretty much covered. Now don't get the impression that I don't like the 300 rum or 338 edge, because I do, but it is just that they wouldn't be my first choice for a lighter weight hunting application, that is all.

Now I will say this, the shorter you go with the barrel, the more I would maybe lean towards the edge. Maybe a 22 inch edge build with a can or something of the sort.
 
Re: Considering 300RUM or 338 Edge hunting builds

I simply meant the A-bolt I have is not built to reach out and touch things like a custom barreled 300wsm or rum would. Nothing against the wsm, I have really enjoyed it. I love the 30 cal stuff and I want a real long range hammer and the 300 rum does that with those 210 vlds. Would a 300wsm with a 20" barrel be worth it? Velocity, energy, accuracy, weight?
 
Re: Considering 300RUM or 338 Edge hunting builds

I've got all my parts on order for a 338 Edge build. Barrel is a 30" Kreiger, (6) 1/4" flutes, MTU contour. Weight wasn't a consideration for me though. If you want to get under 10 lbs on the rifle then definitely go lighter than an MTU. Sendero contour might be a good default and compromise.

The donor rifle (action) I'm using for my build is my Rem 700 Sendero II in 300 RUM. It's a fine round in my opinion, but I really wanted the higher BC of the 338s... and almost more importantly for me is the better barrel life on the 338. Most people say 1-2K rounds before a 300 RUM is toast. The 338 is supposed to be a significant increase as it has the same powder charge but bigger "hole" (not as overbored as the 300).

For a long range rig, I think the whole "you could find ammo for it in a pinch" argument is moot. Even if I did forget my ammo, and I could find some factory 300 RUM somewhere, it's probably not going to be a what most of us would consider a "good" LR load. Additionally, you'll have no data for that load in your rifle, so what good is it? The argument just doesn't hold enough water for me to not build what I really want. Easier to just go prepared...

I respectfully request that you immediately stop posting this picture. Everytime I see it I stare longingly at it for way too long.

Can't wait to have mine built...

I can't really answer that one for you because only you can define what constitutes sufficent velocity, accuracy, etc. to get the job done on whatever it is you are shooting at. What kind of load/velocities with the 210's are you currently getting out of the ABolt? For me, on a perfect day, with no wind,at a known distance, and in an area I will have a reasonable chance of tracking the elk should I fail to miss the vitals, 700 yards is about where I would draw the line. With that decided, for me it is simply figuring out what will get that job done, and 300wm/wsm will, as will the 7mm mags. Everything is a compromise, and for me, giving up a certain amount of theoretical maximum range in favor of a lighter more manuverable rifle is worth it. Your mileage may vary.

I guess I should add that if you happen to be independently wealthy or have multiple custom rifles, than disregard my opinion. Either of the options you are talking about would be exceptionally fun chamberings to have. I just wouldn't choose them as my go to all around hunting rifle. Perhaps you should keep the abolt for busting brush and build the 338 edge specificly for long range applications, that way you wouldn't have to wory about the weight issue.
 
Re: Considering 300RUM or 338 Edge hunting builds

i have 2 matching long range hunting rifle they look exactly the same 1 is a 300rum and 1 is a 300wm. both are under your weight requirements. one has a nightforce the other has mark4. obvioisly the leupold rifle is even lighter. i love the rum the best hunting round ive found so far. i dont ahve an edge but i do have a 338 lapua which is a great round as well. good luck heres a picture of my longrange setup that i used last year
both have 26in carbon barrels and trued remington actions.

good luck with this
 
Re: Considering 300RUM or 338 Edge hunting builds

A better question to better help us understand what your really trying to achieve is how far are you wanting it to shoot with say 1000ft/lbs at the target. There are good options that don't requiter a RUM cartridge.
 
Re: Considering 300RUM or 338 Edge hunting builds

I want to practice out to 1000 yds but only hunt out to around 600, or whatever I can hit a 12" steel at 95% of the time. My 300wsm shoots well, but I dont like the twig barrel. I am really considering a carbon barrel after seeing some of your nice rigs. Would it be worth it to put a nice barrel on my browning A-bolt 300wsm? Maybe a 20" fluted medium palma for a backup rifle?
 
Re: Considering 300RUM or 338 Edge hunting builds

I'd stick with a 300wsm or 300WM, Both will go well past 1000 and with accuracy. No need to shoot a larger rifle unless your going to Africa and expecting to be hunting the big 5.

On your point about barrels and there contour. Its not necessarily the thickness of a barrel that makes it more accurate(for use in hunting a playing at 1000). While ultimately yes, thicker is better, many many guys use thin sporter match barrels in hunting rifles to keep the weight down. The big disadvantage is the inability to do long strings of fire without heat issues. If it were me I'd look into something a little lighter than a sendero contour or maybe a sendero with flutes at 24". That would fit the bill just fine.
 
Re: Considering 300RUM or 338 Edge hunting builds

Flyboy,
Thanks. I want the perfect blend of light weight and accurate. I read a few articles that pushed me toward the light palma with flutes. Since, some guys on here told me go with a #6 or medium palma type. Ideas?
BTW, what do you fly? I am from the Herk community.
