Do .25g BB's make a difference?

Re: Do .25g BB's make a difference?

the point badger makes about them stinging a bit more is due to heavier bb's holding on to their energy for longer than lighter ones, so basically as you increase bb weight you should see slightly improved "killing power" at longer distances

And the reason they 'hold on' to their energy is because they have a higher terminal velocity due to their higher mass. The terminal velocity of a 0.20g bb is actually quite low (in the mid-200's iirc) so as soon as you fire that bb is decelerating rapidly because it just can't sustain that velocity. A heavier bb has higher TV. I don't know what it is for heavier bbs but it should be relatively simple to calculate.

Good point about gas expansion in gas guns!

So what you're saying is.. your gun is hot and you shouldnt be using it?

You dont know what his site limit is he never said he chrono`s on .20`s or that his site limit is strictly 330fps, but you do make a good point.

heavier bbs, not only help in groupings, but also in range.

I personally use guarder 0.28 they are great

Re: Do .25g BB's make a difference?

i use .23s excels in my aegs work great but for pistols and gas rifles use .28s(ie gaurders) or heavier the dont really loss much fps and seem to have better range by far and accuacy as the gas builds up more behind the round. infact a custom meu i built also cronoed at 310fps no matter wat was in it .2 .28 .4 etc didnt matter.weird?! but the .4s went bout 20ms further lol

Re: Do .25g BB's make a difference?

Yeah I seem to remember seeing reports of strange behaviour with gas guns and heavier weights. I can imagine the reactions in my head and understand why but I find it difficult to verbalize the explanation.

Its sort of like, once the gas is released it carries on accelerating outwards behind the bb as opposed to just air which just sort of... flat-lines in terms of outward acceleration.

Anyhoo, I like gas guns and I use Guarder .30's in mine and I believe they're far more harder hitting and definitive with heavier weights...

Also, on that note, I've owned all the Marui shotgun's and I found that they work so, so well on .28's and .30's... Notably better.
