300 Tejas

[Ryan55555]

Can't seem to find much info on this round. Does anyone have any experience with it?

I believe it is a 300 RUM improved with a 50 degree shoulder.

Is it that much of an improvement over a 300 RUM?

How much more case capacity over a 300 RUM?

Is brass life better / worse?

Any info would be great.

There is a member here that I had the pleasure of hunting with last fall that I believe has a rifle in this caliber. The more I think about it - it may be a 338. Tejas. You can try shooting him a PM.

The 300 Tejas is Brad Stairs round. His shop is Wasatch Precision Arms in Ogden Utah. I think he is one heck of a gunsmith. I have had three rifles built but not in the 300 Tejas. I do believe it’s off a 300 RUM case. You can also go to Shooters Oasis.com under gunsmithing There is a comparison on the 300 Tejas.

Can't remember where I read it but I think .300 Tejas is like a .300 Weatherby improved. Or is it .300 RUM AI?

I have a 375 tejas and it shoots a 300 grain bullet at 3200 fps with 111 grains of imr 7828ssc and 350 grain smk at 3000 fps with 108 grains of rl25 from a 31" brux barrel.

338 Bruce,

What is the parent case for your 375 Tejas. From your powder charge I would suspect its on the big Wby case or something similiar. Are those actual chronographed numbers or estimates?

Only reason I ask is because even the 378 Wby will fall WELL short of the velocity your reporting with max loads.

Just curious.

Wouldn't that be considered light artillery? JohnnyK.
