I’m very new to airguns, just bought my first one and shot for the first time a couple days ago. But I’ve already bought several kinds of ammo and I’ve noticed some have deeper cones than others. What effects does cone depth have on velocity and accuracy?
Pellet cone depth

Hope you didn't go out and buy yourself a Hatsan Sortie the guy Was only kidding you know... Yo!

I didn’t realize he was joking, he suggested it twice but either way I didn’t care lol. I knew what I wanted and I got the Sig M17. I’m enjoying it a lot so far.

Don't worry yourself about cone depth as long as it shoots straight right where you're aiming at. Just shoot the pellets that your gun shoots the best with then you'll be fine. Yo!

Right now I am just using for target practice. I know different weights, shapes, materials etc perform differently but for purposes of this discussion I’d like to just focus on cone depth. Not because all those other characteristics don’t matter, but because I am after the simple answer for now lol. Let’s assume all the other characteristics of the pellet are the same or as similar as possible, besides cone depth, would the deeper cone perform much better? Also thanks for keeping the thread on topic I really appreciate it. You said what I was thinking but much nicer lol.

Will depend on several factors, they might affect or not, here is an example https://www.airgunnation.com/topic/art-barrel-daystate-rw-hp-and-jsb-pellets/

I don’t understand the problem with Shooter’s reply. I also don’t understand people’s need to reply with disdain.

Oh I don’t have disdain. I’m just yawning to add some tired and sleepy effect here.
JSB pellets. They are awesome. Try some H&Ns also. Yo is right, you will probably have to shoot a few to see what your gun likes. If it is just target practice then it only matters what hits zero.
Shape does effect how far a pellet will travel in a mass, but since you are merely doing target practice I would say it only matters that your pellet is aerodynamic past 10 yards. You are running subsonic as an air rifle enthusiast, so spend some time learning about that and it will lend to your knowledge about pellets. Under ten meters it doesn’t even matter for target practice unless you are doing something official. Same goes for the type of cast the pellet is. Doesn’t really matter for target practice if it is on paper.
Best of luck

I don’t understand why a question has to “matter” in order to warrant a detailed answer. I’m asking because I want to know. If you don’t know or don’t want to answer, that’s fine just move on. No need to waste thread space.

the cone depth differs mainly with the weight on the pellet. and contributes to its ballistic profile. Some with deep cones may not load properly if the depth of the cone is deep. its skirt with possibly hang over the transfer port some. Shorter cones will easily clear the port. But then again it will depend on what type of pellet probe is in the gun. Pin style versus flow thru.
For instance H&N seems to like the deeper cones, where as JSB and Air Arms like the shorter cones from my experience in 25 cal. Now with my casting. My pellet weight is dictated by how deep my skirt cone is.

Your question was “What effects does cone depth have on velocity and accuracy?”
That depends on what gun you are shooting, the conditions, the alloy, and so on. Maybe you can be more specific so we can help you better. As I said above though, you are running subsonic so it isn’t as much about velocity as it is about accuracy. If you find a pellet you like, and it is accurate, then that is the one you want. Why I said to learn about subsonic ballistics is that pellet stabilization is an odd thing and there is a lot of balance between the head and skirt. You will learn a lot about accuracy with tutorials on subsonic pellet travel. If you are wanting mere velocity, go for the lightest material. They have some non lead options that are very fast and very inaccurate. The lighter and, to use a crude word, pointier it is, the faster it will go, at least when it comes to very short distances (again under 10-15 meters).
Again, best of luck

Looks like the troll ShooterMcGavin got banned or deleted his account.
Anyone else noticed this? That or his account got deleted or disappeared.

If you compare a JSB 18.1 and a 15.89, you will notice the cone depth of the 15,89 is deeper. Both pellets perform fantastic in multiple guns so I don’t think it’s a big deal. One could be better balanced because of how it carries its weight but that’s above my pay grade.

Yeah. Hence my “yawn” above. I like to yawn at trolls, as I am too tired to give any gogo juice to them
