Re: 7 mm Ultra Mag Reloading Tips ( 7mm Tejas )
I did some 7mm-300 RUM's in 1999 and never did any more. Severe throat erosion at 500 rounds. Good luck with yours but from experience I would work up a load quickly and put it on the shelf for limited hunting duty only. That way it can last you many years. This is not a rifle to shoot in the off season. A shot before season to zero, kill your game with it and park it till next season.
Predictions are difficult, especially when they involve the future
