I’m surprised that wasn’t a more popular cartridge. I know it did have some popularity, but it certainly lagged far behind the 30-30.
Maybe because it was less powerful than the 30-30 and it was chambered in the same rifles that cost the same amount of money?
I have a few rifles chambered in 25-35, mostly Savage 1899s, a couple of Winchester 64s, and a 94 made in 1949. When I was a kid, I used a Savage 1899 ASR in 25-35 to shoot 'chucks. I loaded 75 grain Sierras over IMR 3031 in an effort to maximize its velocity potential and had some success before my Father decided that I needed a better 'chuck gun and gave me a Remington 660 in 222. I still have the Savage and probably some of those 55 year old handloads are squirreled away somewhere.
That said, the 25-35 was a lot more popular than either of its direct competitors, the 25-36 MAR and 25 REM. Marlin 1893s chambered in 25-36 are very seldom seen and Remington 8s, 14s, and 30s aren't much more common. The Steven 425(?) and Standard pumps and semi-autos being even more uncommon.
