7mm RUM Barrel length
Is the 7mm rum be better suited with the 24" (31/32 dia) Barrel or the 27 ?" (7/8 dia) barrel?

Most material I've seen on both it and the .300 (which is what I was looking at) shows the longer one. I do have experience with a 26" 7mm STW and it definately performed better with the longer barrel.
These are my opinions (take it accordingly), I did shoot the 7mm over a chrono before and after I had the barrel shortened and recut and it did lose some velocity.0 -
to make adequate use of the powder volume in the 404 jeffries case,.you truley need NO LESS than the 27 1/2" BUT I would go 28" or even 30". Mine is finished at 1" at the muzzle. If this is not a carry gun,....go HEAVY,..and long. Make use of the slower powders and the heavy bullets. Use a 1:9 twist and 168 or 175 gr pills with as high a BC as possible. If you want less barrel,..use less case capacity. The 26" barrel in factory guns is beacause of sales lagging were the company to offer longer tubes. The average shooter doesn't want to carry the long heavy barrel,..which is why they don;t need an ultramag. This is why weatherby went to a 28" barrel on their 30-378 accumarks. It just doesn't really get going until you give it enough barrel to burn the slow powders they were desinged for.
why chase the game when the bullet can get em from here?....

I have had expierience with 2 7mm rums. They were both standard 26" factory barrels (one SS & one blued). They were both very accurate with factory 140 gr nosler partition bullets (less than 1 moa). The problem was the length of the casing caused the powder to burn both ways (with hot handloads) causing a backflash effect. My casing was collasped at the neck.

271/4" hands down if wanting half decent performance designed for.
When Remington intro'd the 300 RUM (I call it/them RUMmy), they bamboozled the public by using in tests, and publishing results on:
> A 28" barrel. You can't get a factory stock 28" barrel.
> A test barrel was used. Not a production barrel.
> Competitors ammo was their down spec'd factory fodder. Making the
RUMmy look good.
Have no problem with the RUMmies, just the poor way of how companies are misleading people.
I call it, "Pinnochioitis" after the way Pinnochio's nose grew.
If hunting in large open fields/plains, the longer barrel is preferred.
If woods hunting, stalk hunting, then a rifle with a shorter barrel, and more efficient cartridge may be more enjoyable.
