I will give the Sierra 90 grain bthp another plug. It has proven to be the most accurate bullet in the 25 caliber rifles I have owned with one exception being the 1-14" ROT Savage 99s.
Just curious as to what issues were you having?
The only thing I could determine was both barrels had a ROT close to 1-15"
Issues regarding them not being dependable.
