Interesting to see the .35 Rem. ballistics with the 200gr. RN bullet.
I checked a VERY old Hornady manual which has 4 loads for a 250gr. RN Hornady bullet to 2,800fps.
It also has 275gr. Hornady RN data with 5 loads(dif. pdrs) to 2,600fps.
I have a written in load listed for 300gr. at 2,670fps. I suspect this was from a gun magazine article from the 1970's.
In it's normal front page description writeup, Hornady notes that Norma brought out this ctg. in 1959.
