Trajectory effected by pellet weight and design?

What effect does pellet weight and design have on trajectory? I changed pellet brands and weights trying to see what my break barrel likes best. was doing well with some domed Crosman 10.5gr. domed. Got tighter groups with RWS superdomed 8.3gr. Then got some Barra 10.03 domed (more like a pointed dome) and they are shooting high. I mean like missing the paper . I am shooting 25 yards , not far . Do heaver pellets hit high at that distance ? Or are these pellets just not for my rifle ? Thanks for your reply's.

.177 pellet with least variance in manufacturing

Have a Walther Lever pellet rifle- Wells Fargo model. Love the gun. Bought extra magazines, have the original model- uses 2 12 gram co2 capsules. Usually use one new capsule, one used. Get about 7 magazines, 8 shots per so about 55 shots before changing it out.

As I load the magazines, sometimes the pellets just don’t fit so I discard those . Thought initially it might be the magazines but switching out the pellets solved the problem and prevented jams.

Am using Crosman Wadcutters. Will spend more money to get better consistency in the pellets. I believe I am seating the properly so it would appear to be some inconsistent manufacturing.

Any recommendations on another product and or seating advice is welcomed.

What are some over sized .25 pellets? For loose bore .25

I have a hatsan 125 in .25 with a over sized bore. My tuner says it's losing velocity because of how wide the barrel hole is. Do you have any pellet recommendations for this. I want a wider diameter skirt not the head. Hatsan will not replace the barrel. Apparently this is a big issue with hatsans. I've had the gun for 4 years and I like it. Just looking for some ammo to get full potential of power and accuracy with the gun. It's accurate it's just losing about 80fps because of the bore diameter. domed and pointed pellets are my ideal type of pellet but I won't be picky if someone can provide a good pellet.

Vevor air compressor

I purchased a VEVOR air compressor exactly two years ago, have used it twice. I went to use it the other day. I attached it to my gun, Made sure the bleeder was closed. I turned it on, let it warm up, then turned on the compressor, in about 15 seconds everything shut down. Has not started since. Any thoughts of what it might be?

Huma air contact

I contacted Huma through their website contact option, and they reply by email requesting some picture. So I hit replay on that email that I got from them, attached the pictures and sent them. However haven’t received an answer back yet. I did replayed a second time to that same email, in case the first one did not go thru, and nothing. So I was wondering if that email you get after contacting them thru the website can be replayed to… or do they have another email that has to be used that am unaware of? Any help is appreciated. Thanks

Fixes for Hatsan 125 .25, barrel hole is over sized?

I was getting my hatsan 125 tuned and the tuner called me and told me my barrel hole is over sized. The pellet fits snuggly in the breach but after that the pellet fall through til the end of the barrel where it gets tight again. Kind of like a choke. The tuner said the barrel is so over sized its actually slowing the pellet down. He has experience with hatsans and says if I buy a new barrel from them there is a big chance I'll get another bad barrel. What would be a good fix for this? Are there any airgun barrels for these that would fit it ? I need recommendations.

whats the best way to make a dope card for my particular PCP gun and my ammo ?

I have been studying rifles and scopes and reticules ect and im realizing that all of the info i studied is for normal guns with factory ammo that fire roughly the same fps and fpe every shot and all of the mobile apps are really technical and dont seem to apply to my setup at all, although an MOA is still and MOA so i figure this can still be done

my AEA megalodon 22in .58 cal is not even regulated but for the first few shots its roughly the same and is strong enough for 100 yard deer hunting but im not sure how to make dope card that will be reliable in the field so that i will know what moa adjustments i to make once i know the range of my target

I dont yet have a chronograph to test my fps so i would for now rely on youtube videos where they shoot the same exact gun and same exact ammo to get my average fps of 750 with a 335 grain slug with the scope zeroed in at 50 yards

I might be missing something as all of this is pretty new to me, anyone here have hunting or 100+ yard shooting experience with these big bore airguns ?

what kind of cheat sheet can i make so i can quickly and accurately take a shot at 100 yards or 150 if my scope is zeroed in at 50 yards, or zeroed in at 100 yards and i wanna take the shot at 50 yards or maybe im on a hill and deer is 200 yards out maybe thats possible with this gun im not sure yet more testing needed, any wisdom shared will be greatly appreciated thanks

Tuning  Regulator Question

I have a HUMA regulator set to 140 BAR in my .22 700 Panthera. I shoot this rifle tethered to a Nuvair external regulator. Up to now, I've set the external reg to 250 BAR because the HUMA internal reg seems to recover faster with high bottle pressure. The question is: Does the internal HUMA reg respond better, considering both performance and wear, to a large pressure differential (250 BAR/140 BAR) or would it be better to turn the external reg down to say, 200 BAR.

Benjamin  Tuning help? SSG and Regulator questions .22 Marauder silent backyard shooter

Original Gun:
.22 Benjamin Marauder LW barrel
Pellets: still experimenting but usually 25grain ish JTS are current faves but haven’t tried JSB. Apollo are trash lol.

Goals:
I don’t want to disturb neighbors but I want to be able to kill gophers at up to 40 yards (12+ FPE)

This is my first pcp and I’ve made a lot of modifications already. Some things I have already gotten rid of like the Airgun Revisions SSG and a hill depinger as I’ve found new things that are better suited. (One day I’ll be able to sell these on the classifieds :p). I’ll be honest, I’ve got most of my info from ChatGPT but I feel like I’ve hit a wall.

Heres what I’ve got currently installed.
1. Hill Regulated parts kit- this is a big kit that involves; high flow transfer port, Hill Valve with lightest spring, super light aluminum hammer with PEEK striker, barrel inlet port drill bit, de-burr bit

2. Jefferson State TSS and SSG- I will say, it was weird needing to buy the TSS to use the SSG but I got extra springs out of it (one useless though) but I think this is a sophisticated SSG system so I went for it. They give you a new back end to your hammer you can screw the SSG into and make lots of adjustments on the fly.

3. Huma Regulator XXL - ChatGPT told me having more air would allow me to not hit the valve as hard for the same power so it would likely be quieter. Made sense to me.

I have some other fun accessories but that’s what’s important in terms of tuning.

ChatGPT had told me to set the regulator to 2200.. that was no good. It said oh my mistake let’s try 1800 so you can still be quiet but still have some room for extra power. The shot isn’t the problem it’s the mechanical noise of the valve and the hammer.

Right now (1800psi) I can get the noise near silent at around 550fps (25grain), but when I load up my hammer more the noise increases. I think I could get more out of my shots than I am already if I used a heavier spring but I was able to raise the power up to about 830fps but I was getting a considerable ping again, and I think my hammer was bouncing again despite the SSG.

What psi should I be aiming for? I have a feeling the back pressure on the valve is still significant enough that I am needing to increase spring preload more than necessary for the velocities I’m aiming for. As much as I love degassing (can’t use a tool with PEEK striker) pulling out my regulator and adjusting psi and then hand pumping from 0 over and over.. I’d much rather hear from someone who has some experience help me out here.

Additionally, if anyone has experience with the JSAR SSG could you help me understand how to tune with it as well? Theres two differentl Allens you adjust big/small.. the bigger one makes more sense to me, the farther in the more power in the spring. The smaller one makes less sense to me..

Thanks in advance to anyone who can help!!!
