7mm Rem Mag

Then my vote would be buythe Sendero in 7 RM and bore the chamber immediately to 7mmSTW before ever firing a shot. I love my 7mm RM, but for 1000 yards and beyond abilities, I wouldn't even fool with it....That is simply my opinion. If I had the coin, that is precisely what I'd do this very day.

I would never intentionally steer a fellow gun nut and LR hunter into a bad direction, purposefully. I am trying to be as honest and helpful as I can.

I don't like the RUM's. They have horrible throat erosion and horrible barrel life, yes, even compared to the STW, which is a moderate in that category...not the best, but certainly not the worst.

And to the OP, if you do go through with the 7RM or buy it and convert to 7STW, I can give you some smokin loads to try that should shoot nicelg out of your Sendero. Just let me know if I can be of any belp in any way. Feel free to PM with questions or anything. Just trying to help a fellow shooter.
 
yes have decided to go with the sendero but for the sake of this current thread i never specified which .300 cartridge i was considering. Somehow a WM got the popular arguement and there was just plenty of great info floating around that i myself never mentioned the .300 RUM. Does the RUM change things? As for the 7 STW, ive heard about it but know nothing about it other than ive heard it eats up barrels....Does the 7STW trump the 7RM and the .300WM considering all of the factors we have discussed on this topic? How hard/expensive would it be to convert the 7Rm to STW?

thanks for your consideration, i will keep your offer in mind!
 
If you have cocerns about the 300 WM recoil, don't even think about a 300 RUM unless you brake it or use a slip-on decelerator recoil but pad. That said, the 300 RUM will get you an additional 150-200 fps over the WM using the 215 Hybrid... or shoot the 230 Hybrid at about the same velocity or a little more than the 215... I would use the 230 and will be as soon as I get some.

It will basically give you about another 100-150 yds of "effective range" over the WM and 7RM.

For your stated goal, the 300 RUM would be my choice because it will give you more a good bit more smack @ 1000 yds. The barrel life will be about the same as the 7 RM.

There ya go, short and sweet.
 
Southpa,

I'm starting to think of the kid who walks into the candy store for the first time with his friends and looks behind the counter with all those choices. All of those goodies so tempting and the mind running on anticipation just how each one would taste. But the little kid only has enough for one candy. The baker shows the kid all his favorites assuring each one is made to perfection... the choices the choices. Pick the white one, says a friend. No pick the yellow one says another. Maybe it's time to leave your friends outside and pick the one that you have that gut feeling for.

I'm confident whatever decision you make won't be the wrong decision. Learn as much as you can with your selection and strive for perfecting the rest of the equation. LR shooting can be a giant beast with the gun only one piece of the pie. Research, practice and when possible find someone with experience to assist when you have difficulties. You can always expand once that first success and addiction sets in but we all have to start somewhere.

Good luck and I wish you the best.

The OP, being a novice shooter, is NOT John Burns.... hell why stop there? Lets give German Salazar a call... or better yet, lets call David Tubb. You sir are comparing apples to oranges.

A well built & fitted rifle WILL mitigate recoil but it cannot make up the difference in internal performance.

I have shot against/ with German ; but not david. AMAZING with iron sights no less!

They don't eat up barrels like most folks who've never owned one will claim they do. I've had my Sendero SF that was a factory built 7STW for 11 years now (since new). Barrel is still perfect. Granted, I've probably only put a couple hundred down the pipe over the last 11 years, and since reloading recently I have been shooting it alot more.

Barrel life is not the best, but it certainly is not the worst. The RUM's eat barrels up significantly quicker than the STW does.

It shouldn't cost more than a couple hundred bucks to have the chamber reamed and then have the head-spacing trued when he re-installs the barrel.
 
You know where I stand on the 300 RUM :) As I mentioned, I chose that over the 7 mag, 7 RUM, and 300 win. The major deciding factors for me were flatter trajectory (only about a foot of bullet drop at 400 yards means I could easily hold for that shot instead of dialing) and more killing power further out. I could also use one round for all big game animals in Colorado including antelope, deer, elk, and moose.

I know it is a little added recoil, but nothing I can't handle without a brake. I have considered a brake for it, but I do a lot of hunting where it could be closer quick shots without the opportunity to put in ear plugs and my hearing is bad enough the way it is! The only other downfall I saw was barrel life, which didn't concern me too much. By the time I fire 1,000+ rounds through the barrel and it is shot, I will want a new barrel anyway! :)

The RUM is one bad boy, properly setup & coupled with the 230s should trump pretty much everything except the BIG 338's. The down side is, you're touching off another 10-15grains of powder, that equals a pretty significant increase of recoil. I would not set one up without a brake. You're going to be in the 90.0 - 93.0 area as far as powder charge vs 75.0-80.0 for the STW. I didn't hit the recoil calculator because I didn't think it was necessary, 50grains more bullet + 15grains more powder :rolleyes: that's gonna kick a little. :D


Now as far as bbl life. The STW & RUM are both uber performance cartridges & both will toast a bbl relatively quickly... well, quicker than the RM or WM anyway.

Accurate shooter's bbl life calculator states:

7STW w/180 Berger
75grains of H-1000
BBL Life= 1309 rounds

300RUM w/230 Berger
91grains of H-1000
BBL Life- 1230 rounds


Not exactly a deal breaker at 79 rounds, then again, that is simulated data. Get them hot & continue to shoot, you can torch one in well less than 1k rounds.

MudRunner is right on, a rechamber job is ~$150 & not a bad idea at all. One thing I was cautioned on was, sometimes the reamer can get a little goofy & FUBAR your brand new barrel.... i've had a couple rechambered & it has never happened but is possible.

If a Smith goofs my chamber, they owe me a new barrel, and the labor to put it on. :D

Yes, it's possible for something bad to happen, but find a good reputable smith and you should be just fine. The odds are very slim of something going wrong during a routine chamber reaming. I am lucky to have several good smiths in my area. We have several here on the site. I bet Kirby could do it pretty quickly, too. Rechambering don't take long at all.
 
Rechambering to an STW will get you about another 150 fps, so a little better external ballistics than the WM, but the WM sti ll has better terminal numbers. With the cost of a rechamber you could put a brake on 300 WM or RUM.

I am looking on Gunbroker at Sendero's. Are they really costing $1650 new?

I could go find an old Vanguard/Howa for about $200-$300, (which IMO is a better action than a 700) and
Custom match grade barrel $350
Manners Stock $550
Smithing $600

And have a custom grade rifle for about $1800

All components superior to the Sendero for another $150 or so.
