375 Tejas?

[FOTIS]

Ok guys, I know this is a 375 RUM Improved but I have heard some unbelievable velocity claims with it.

I have heard:

3300+ with a 260 gr
3100+ with a 300 gr
and 3005 with a 350 SMK

What gives? I have had a few 378 Wbies and none could safely come close to these claims.
Are these people using 40" tubes?

Anyway what do safe loads really produce?

This is what I found,
http://www.longrangehunting.com/forums/f19/375-tejas-rum-improved-45360/

and I got this from another website,
(375 ULTRA on the high road forum)
"My rifle is a rem 700 sendaro 375 rum improved (tejas) with a 31" brux barrel 1-10" twist. The 300 load is 111 grains of IMR 7828 ssc at a velocity of 3200 fps. the sierra 350 smk load is 108 grains of reloader 25 at a velocity of 3005 fps. Im still searching for the perfect load as the reloader 25 has a little too slow of a burn rate . I cant get enough rl 25 in the case ."

Yup one of the ones I have read. Just seems so unrealistic........

Fotis,

Can you SWAG it with Quick Load?

That is some serious HP they are getting from the RUM case, granted it might be way over pressure, but man, that is some speed. Scotty

It seems like the regular 375 pushes the 260's to 3K, I can't think of anything that needs more.... Whats a couple clicks on the elevation or maybe an extra for windage! That is some serious firepower. I like it! Scotty

I think I know what my next rifle is going to be. :lol:

I gotta wonder how long of furrows a guy could plow with the recoil from that monster.... 8)

Q/L does not agree with #'s posted. No surprise there.

Here read this..... towards the end

The only thing I can think off is that since the rum brass is so tough (as opposed to the softer WBY) pressures are running at insane levels.
I can not see any variation of a RUM brass outdoing the 378 BEE which is so much more capacious.

This is my rifle and the pressure is about the same as it was when it was a factory 338 rum shooting 300 smk at 2740 fps and 250 hornady at 3050 fps. It does have a 31" barrel. It does hurt the brass if pushed harder and on a hot day with a warm barrel the bolt will get a little stiff. The gunsmith also chambers a 7mm tejas pushing a 180 berger at 3400 fps with more than 2500 rounds and no loss of accuracy.

What kind of accuracy are you getting from this rifle? and how is the recoil?

 

[375ultra]

My accuracy is about .5 moa out to 900 yds with the 260 AccuBond and 1260 yds with the 350 smk. I havnt tested beyond that yet. You would think the recoil would be worse as it broke off the scope base screws and I cant keep the scope from slideing. I had to install size 8 base screws. I had to use a 3/8" bolt to hold the bipod on as it would break the sling mount screw in 20 or so shots. But it dosnt hurt the shooter, my 120 pound daughter dosent have problems. The recoil is slow but very long.
