Tuning Recoil same FPE but different projectile weights?

[MushroomPsyche]

What do you think will be more sensitive with guns shooting the same FPE but different pellet weights? The reason I asked is because for a few years, I've shot a Taipan Veteran Long .22 15.89gr at around 30 FPE and never had issues with hold sensitivity. I never even thought about hold sensitivity at all with that gun. Now, I'm shooting a Taipan Veteran Short .25 25.39gr at 25 FPE and I feel the gun is so much more hold sensitive than the .22 gun ever was. I feel the .25 Short really likes to be held tight against the shoulders. What do you all think? MOST of my shots are between 30 and 40 meters for either guns.

I've found the bigger the pellet the bigger the "recoil". Larger caliber and heavier in weight the more sensitive it can be. Granted shooting lower power should help but just how I see it.

Seems that's what I'm seeing as well. Also, the slower speed of the .25 (longer lock time) surely doesn't help either.

I'm not familiar with the Taipan Veterans (don't think they are available locally) but did take a look at them out of curiosity.

Agree that a different in recoil can affect shooting but I think that the compactness of the Taipan might be the issue.

I'm just basing that thought that (in my experience) longer rifles are more stable and shorter ones more sensitive/twitchy.

Personally, I prefer a rifle with the center of balance more forward on my target guns and centered on my plinking, pesting, hunting guns. The weight forward is less inclined to move and the more centered ones quicker to handle.

Just a thought.

Cheers!

That darn Newton. It is all about mass. Heavier pellet accelerated from rest requires more energy than the .22.

Been a few years since I took a physics course but I believe the term was effective mass. Time under acceleration, velocity and origin mass make the pellet appear heavier to the source mass (the gun) when fired. The effect on source mass varies according to its mass. Lighter gun, greater effect.

At least I think that's how it worked 50+ years ago.

Well, your .22 is shooting over 900 fps, and the .25 only around 700 fps. That is a substantial difference in pellet barrel time. Couple that with the shorter rifle, which is inherently more difficult to hold, and I think you have your answer. I would tune the .25 up as much as practical, which might require a regulator adjustment. But, with the shorter barrel, you will be handicapped with the .25.
