I saw on YouTube on a few videos different ways that you can make your pellet both heavier and hit harder. It is also said it gives it more fps.

In a nutshell you would use a hollow point pellet then superglue a BB on to it .

I saw that using a BB or other Ball bearing would be better because it is made of a harder material than using a heavier lead pellet & and according to the people that did the video it would also hit harder and do more damage.

Personally not knowing much about this kind of thing I would guess it to be okay but I’m not sure that’s why I am asking all of you.
If you all do think it is okay I was wondering if a BB was okay or should I use a smaller ball bearing.

I would like to find out if doing that is advisable and or will damage the Barell of an airgun.

Why would you want it to be harder hitting?

If you are using it for your P17 - I doubt that there is enough fps to warrant it.

If a pellet becomes heavier by gluing something to it, the pellet cannot go faster. The laws of physics do not permit this in these circumstances. To "hit harder," means to hit with more energy, which is a relationship between mass and velocity. If either is increased the result will be more energy. But with a given source of power (i.e. the power plant of the gun in question), the power remains relatively constant. Generally speaking, if the mass goes up, velocity goes down and vice versa.
In a low-powered airgun such as the P17 it is unlikely that gluing a BB onto a hollow point pellet will do anything remarkable at all, except perhaps reduce accuracy because it may not be possible to glue anything onto a pellet with consistency.

I enjoy watching/hearing of people cool and maybe innovative ideas. But you working on designs and ideas, don't recreate the wheel! BB embedded pellets already exist, a few companies make them now.

If "hit harder" is interpreted as Momentum instead of Energy.... and there is merit for doing that.... then adding weight to a pellet will do that.... However, the velocity will decrease for sure....

Why not post this question with the specialists at the youtube page features this video, in the comments section? The users here are more interested in common sense stuff, you know, your dull target shooting with ammunition that won't damage your gun's barrel or waste their limited time making some mickey mouse BB when they could be shooting their guns instead.

Last year I glued phosphorus from wooden matches (careful ground wet, then dried once finely ground) into the backs of some pellets with BBs glued on top. Figured the steel BBs would help the powder ignite. But I still haven't had time to get out of town to a safe plinking spot, so I have no idea how well they'll work. I do know that when I do eventually get around to it I'll be shooting around 500fps from my Atomic carbine, and that the potential for the BB coming back on me at closer target ranges is relatively high, so I'll be going for 30 metres and beyond and see what happens. A silly thing to try, but as has been said very well above, zero potential for increasing power. Increased mass equals lower velocity. There is perhaps some slight BC efficiency to be gained from the rear-mounted BB converting a normal waisted pellet into a semi-boattail... but I've no way of computing that, and someone vastly more expert here can likely dispel such thoughts with a simple bit of physics explained. Basically though, you'll have to increase the power output of your airgun if you want a heavier projectile to go out the muzzle at the same velocity as a lighter one.

The op did specifically say ... " Personally not knowing much about this kind of thing I would guess it to be okay but I’m not sure that’s why I am asking all of you.
If you all do think it is okay I was wondering if a BB was okay or should I use a smaller ball bearing."

If you are looking for more punch on delivery at target then a better option is to get heavier pellets; manufacturers do offer pellets in different weights.
As stated before .. some already offer pellets with BB heads, but I have yet to see one with steel BBs (not to say they don't make em) the ones I've seen are copper or copper coated.
Copper being softer, doesn't chew up the barrel as plain steel would. So if you absolutely MUST try this, then go with copper.
Keep in mind that there is a lot of pressure at the breech & all through the barrel, besides the lead deposits you really don't want any other build up .. like glue residue.

Anything else you wanna know - ask away .. this is the best place to do it :)

ps: for different pellet weight offerings Google JSB or H&N pellets.
Plenty available online & some local Princess Auto etc.

Did it with crow magnums and bb's, shot through my XL1100. Shot gophers for a couple hours. Accuracy suffered. Trajectory was a little more loopy.

Would I do it again. No, but I can say I tried it.

As for the bb ricocheting as stated above, the bb's/pellets I recovered from shooting them at soap and things I could recover the pellet from, the bb was completely enveloped by the pellet. Quite amazing.

You can play with it if you want, but don't put a BB onto a 177 pellet, only larger bores. You don't want that steel BB touching the rifling because it is likely harder and will damage the lands. BB's are also often not exactly round and can get stuck in the bore which will most certainly cause damage. So if your gun is 177 then you need to find some bearings that are smaller, maybe .014 or less. There really isn't any point (pun intended) to doing this mod other than breaking glass, punching holes in sheetmetal etc. Lead pellets typically splash like a raindrop when they hit glass or steel, but there's little point unless maybe you want to shoot a hole thru a penny or something for fun. If shooting vermin then the BB tipped pellet will pass thru it easier leaving a smaller hole and much of the energy passing thru. A lead pellet, especially a hollow point, will transfer more energy to the animal and do more damage to it. So for animals I'd say it's a bad idea. Then there is the huge hassle of doing this so it would only be for a few pellets for entertainment, and there is a much bigger ricochet danger. BB's bounce like super balls, lead pellets bounce like soft clay. Then there's the problem of them not being precision so they won't be as accurate. The weight added will drop power in a springer, but likely increase power in other guns, but not by much. I think an easier way would be to buy the pellets with the steel balls on them, or by alloy pellets with are also rather hard compared to lead and work good for shooting holes in things like coins, breaking glass etc.
