The Remington is the same rifle as the wood stocked Benjamin XL Nitro piston rifle which also broke scopes and walked scopes and even broke the welded on rail.
So what portable (7 pounds or less and under 40 inches length) quality .25 springer is suggested that can make 24 to 30 fpe? Is there an under lever or side lever .25 in that power range?
There is no such gun, as you know, but no need to be, either.
In my early springer days, I used a Spanish lightweight breakbarrel for all my airgunning needs. As the lightweight gun broke down from ordinary use, I checked the German springers online: oh man, they sure are HEAVY. Who would want to carry a 8 - 10 pound gun in the woods? Then I started to actually buy heavy German springers, and learned that a) they are heavy for a reason and b) heavy is a 100% subjective thing. One man's heavy is another man's just right. In no time at all, I was carrying c. 10 lbs. of springer wherever I needed to. That became the new normal, organically.
Many of the HEAVY springers are actually quite compact, and balance really well - like my sidelever Dianas and my LGV. They carry well and point even better. Weight is only one variable. I'd rather take a short, heavy gun than a lighter weight flagpole to the woods. Of course, many guys opt for compact AND lightweight guns, but those do no meet my needs, as springers are not a squirrel sniping / target practice tool for me.
One thing is for certain: once you settle for small, lightweight guns, even medium-weight, medium-size guns start to feel surprisingly heavy and awkward. It's so very subjective. And once aging sets in, there's no going back. Use it or lose it. YMMV.
