My REM 700 in .35 Whelan never misfired. But I only used Remington Factory ammo & cases.
Neck-sized brass only, never had a problem. But the extractor probably held the case head tight to the bolt face.
By the time I got around to sending my .223 Handi back for a .35 Whelan bbl, it was too late.
Parrot1969 is right about one thing.
The Original 250gr Factory RN Load does shake your Head and Rattle your brain. And cause your eyes to cross. But it only takes 2-3 minutes to recover for the next shot.
The 200gr RN #358318 Is a great plinker.
Geez I miss that Rifle.
