I'd call it a barrel maker's dream come true!

for sure will be a barrel burner at least, its basically a 300 rum with a la ackley shoulder for a 10% gain in case capacity, yes you can go up to extreme a use very hot loads with very short case life 2 no more than 3 loadings and get the velocity up, think the .300 Win Mag will always be the king. if you want something with more authority go to the .338rum or .338edge they mark a difference.
by the way sound good .300 tejas,hihi

Re: 300 Tejas

Just read this old post,

500 round barrel life at the most, COME ON GUYS!!!

Coming from someone that has designed and released over 25 wildcats in my Allen Magnum and Allen Xpress and Allen Tactical families of wildcats that MANY of which have expansion ratios that make the 300 Tejas look like a 308 Win, you will get MANY more rounds down the barrel then 500 IF you take care of your barrel, limit shot strings to 3 rounds and keep the barrel clean.

I have many dozen 338 Allen Magnums in the field that have well over 500 rounds down the bore and some pushing 1000 rounds down the bore. This round makes the 300 tejas look like a popgun with its 145-150 gr powder charged and driving 265 to 300 gr bullets to 3300 to 3550 fps.

Not trying to flame anyone here but the claim that overbored chamberings are nothing but barrel burners is simply a falacy these days. With our modern barrel steel and modern powders, its not like it was many years ago.

My 7mm ALLEN MAGNUM for example has a slightly larger case capacity then the 300 Tejas and necked down to 7mm and when cared for properly they will last close to 1000 rounds down the bore easily.

Just can not sit back and hear this bashing as its simply not true. I feel its based more in inexperience more then anything else.

That said, if you want a rifle that you can put 100 rounds through every shooting session, get a smaller gun because you will burn the throat very quickly. If you want to shoot 10 shot strings, get a smaller chambering.

These rifles are designed for long range precision big game hunting, not high volume shooting, use rifles as they are designed and they will last a LONG time. My personal 7mm ALLEN MAGNUM has been in heavy use for over 8 seasons now, It was used originally for load development and ballistic testing for R&D for that wildcat, and not overly nice to it at times. I figured it would be ready for a new barrel several years ago and have a new barrel sitting on the rack ready for that use. Its been sitting there for 4 seasons and last year when I varified the 100 and 800 yard zeros the rifle shot a 3/8" three shot group at 100 yards and a 4.5" three shot group at 800 yards. This out of a 7.5 lb bare rifle weight rifle in one of the most extreme chamberings on the planet and after around 800 rounds down the barrel.

When I released the 7mm AM all I heard was how you would not even be able to develope a good load for it before the throat was burnt, BUNK. Don't fall for the opinions, learn the facts and take care of your rifles bore and do not overheat it.

Just wanted to add some solid information for those that may read some of these opinions and become spooked by the very short barrel life charges. I tell potential customers all the time that if they use the rifle as designed, they will last a very long time, barrel life has more to do with how the owner uses the rifle then what the rifles chambered in.
