Found 'em. Thanks

Think I'll make a trip down there see if I can "gleep" onto some and do some testing while down there.

RUMLUVER · #62 11-22-2005, 01:42 PM

Let me know how it turns out for you and I will do the same when get my hands on some and do some testing with my .338 RUM!

338 Win is nothing to sneeze at.

fired a Sierra 250gr game king at a 2 liter bottle of water (end ways) target was the cap. Base of the bottle was against one of the railroad ties (8 inch width) at 200 yds.

Miss the end cap by a breath. Explosion was really awsome. Some parts of the plastic bottle just dissappeared.

The amazing part, at least to me, was that the bullet fully penetrated the 8" of railroad tie and kept on going. I was and still am impressed.

Also, if I shoot a 1/2" - 3 shot group at 200yds which happens on a regular basis, the second and third shots penetrate the 8 inches of wet blow sand (really fine).

Sounds like like you got yourself a helluva rifle there Roy! I can't wait to see what I can do this summer with the new 250 TSX's. I will do some penatration tests just for the hell of it and to see exactly how far these bullets will travel. Thanks for the story about the Win Mag!

As soon as you get some accuracy experience on those TSXs please post.

I've had no luck with Barnes and accuracy.

RUMLUVER · #66 12-07-2005, 10:38 AM

Roy,

I was always told the same thing that the standard X bullet was inaccurate and was a realy bad copper fouler. I tried the TSX bullets in my .300, .338, and .7mm and so far they have been accurate and easy cleaning. My brother shoots a 130gr TSX out of his .264 and shoots groups at a 100 yards that are the size of tylonal tablets. But when I get some test results from that 250gr TSX I will be sure to post the targets. By then I may have a digital camera to get them on this site. If its and good to you I shoot a 210gr and 225gr TSX and 1/2 groups with those quite regularly.

Reading about Roy's 2 liter and tie reminded me of some steel plates we shot. The one below was shot with a 300WSM and a 338RUM. It is a 3/4 in plate that was shot at 200 yards. If I remember right we had a few go all the way through. The 338 was loaded with Hornady Soft Point Interlocks and I think the 300 was loaded with Nosler Balistic tips.

Front side.

Back side.

Dale,

What are you using for a load with those Hornady Interlocks and grain wieght are you using just currious?

Dale · #69 12-08-2005, 10:19 PM

88.5 grains of RL22 & a 225 gr. Interlock.

RUMLUVER · #70 12-08-2005, 10:48 PM

Dale,

In my .338 RUM I'm using 92.0gr of IMR 7828 with a 225gr Interlock and getting 3150fps with 5/8in and better groups. I'm also using 90.0gr of IMR7828 and 250gr Interlock and getting 2987fps. What are you getting for velocity?

Dale · #71 12-09-2005, 09:09 PM

Don't know. How's that for an answer. I don't have a chrony yet and it doesn't look like Santa is gong to bring me one. I plan on adding one this next year. Book velocity puts it around 2900. Wont know for sure till I get a fast bullet measuring thingy.

RUMLUVER · #72 12-09-2005, 09:26 PM

Maybe if you were real nice this year Santa still might be considering it! If not hope you get one soon it gets real intresting when you find out what the "book says" and what your load and rifle are actualy doing. I know I've been surprized more than once when I ran some loads through a chrony. Most recently it was some loads for my .300 RUM and some Barnes bullets.

RUMLUVER,

Well, I'm about to do it.

Its getting pretty boring shooting the 338Win after all the kinks are worked out. Its probably one of the better shooting rifles I've owned but as some said, "It ain't sexy."

Found a new/unfired 338 RUM bbl in sporter config. at a super price and from a trustworthy gunsmith. I'll put another 225 or so into it getting the bbl and brake switched and add a tubbs recoil lug then we'll go to playing with it.

I'll pillar bed the stock then probably re-skim bed it.

That ought to stretch my range several hundred yards.

It'll be a neat cartridge/chamber/barrel comparison. The Win gets the 225 Hornady to 2900 and the 250 Sierra to 2850. I would expect to get the 250 to at least 3000 with the RUM with a decent level of accuracy.

Also think I'll get it throated so that the base of the Wildcat 252 RBBTs is at the base of the neck.

Also it will be a single shot so I don't have to have the rails messed with. The smith will "glue" in one of those single shot inserts.

I don't mind a single shot at all except if me and a griz ever get to scuffling over something I shot. Then I'd do my shooting from a bit of a distance then put the muzzle at the entrance wounds and shoot again. Figure that brake would make some unmistakable powder burns.

Otta be a pretty good excuse wouldn't cha thinK

Roy,

Sounds like your going to be having alot of fun with that .338 RUM project. Let me tell you that you will not be dissapointed when your done that .338 RUM is a very accurate caliber and with what your doing there it will be a tack driver. Also with reloading it won't take much to get 3000fps from the 250gr slugs I have 2 loads that do it now. You must post some pictures when this project is done. I want to see the end rusult. I will post pics of my .264 Win Mag project when I'm done with that but as for right now I'm still waiting on my barrel.

royinidaho · #75 12-17-2005, 01:22 AM

Here's my plan.

After the RUM bbl is installed I'm going to do the standard Lilja barrel breakin procedure and see how that goes.

Then I'm going to do the Final Finish/Tubbs thing with the abrasive bullets and polish it up a bit and see how that pans out.

Then after that I'll.............................
