Heavier BB's accuracy

Re: Heavier BB's accuracy

There are other up grades you can do to hops to impart far more hop over standard. There are a few people trialing some modified hop ups now with very good results.

All this follow through and wind is giving us a bad name...lol...

Follow through is keeping the gun still through the cycle. It was suggested the optimum barrel length was somewhere arround 300mm, mainly due to the fact people jerk the barrel arround. For accuracy and range, I would want something longer.

It was also trialed and found that the Element hop rubbers were as good as the Guarder clear.

Re: Heavier BB's accuracy

I've always found that .28's and .30's appear to fly further and straighter than .20's and .25s... Even in pistols. To be honest I haven't bought anything less than .28's in over a year...

Re: Heavier BB's accuracy

Funny you should mention this. I was doing some research today, the person had carried out endless tests on every different fps, weight everything. His conclusion was that you got better distance and accuracy with 0.3's than you did with any other weight at 350 fps.

With 0.25's giving the flattest trajectory.

And 0.2's having least range.

The variences are all feet mind, nothing earth shattering. But supprising none the less.

So best accuracy 0.25 with the least variance. Not a lot in it give it a bash.

Also his research showed that 0.3 was the best for 500 fps too.

Sorry to quote from near the top of the thread, but could you tell me where you are getting these results from? It sounds like its well worth reading through...

Thats fine, I'll pm you.

Re: Heavier BB's accuracy

For the love of christ, why do I have to keep seeing this topic come around and around and around!

There is a graph somewhere, it's interesting. .2s aren't ideal, .25s are in fasion, Range<>accuracy.

Re: Heavier BB's accuracy

In my svd firing at 460-500 fps i use .28's but i think .3's would be best and it hurts more

Re: Heavier BB's accuracy

because looking at graphs is a pain as i seen too many this year lol and its annoying to understand it when im trying to get estimations for people who tried them

Re: Heavier BB's accuracy

@kinglemon - that wasn't aimed at you. It was more the fact that someone asks the question, and the same people end up posting the same things every time. Can't we just save the thread somewhere so it shows up in searches. That said, the graph is very interesting. Various fps-weight-range comparisons. I probably should have just avoided the thread.

sorry major

Re: Heavier BB's accuracy

Z1 .2's in Pistols- Works surprisingly well in my 1911... about 30m range.
Z1 .25's in AEGs,
BAW .3's in Sniper Rifles.

Simples. Doesn't ever fail me, I run both an L96 and SVD on .3's with great results.

EDIT: Z1 really should bring out some own brand 0.3g BBs...

Re: Heavier BB's accuracy

Been using .25gs for well over a year now i all of my aegs and I've definitely noticed a diiderence in both range of accuracy even in my short barrelled weapons. In pistols I use .3g and again the accuracy and range is dramatically different to .2g. I wouldn't ever use the lighter ones again.

Re: Heavier BB's accuracy

the point is that i am trying to get a estimation of what range i will get with .28's

if the fps i shoot with .2's is 330fps

Re: Heavier BB's accuracy

In that case, 0.28g's you can't go far wrong. I'd estimate around 40-50m dead accurate range. Really depends how/where you play.
Don't forget a good quality hop can make the world of difference too...

CQB, w/a full auto gun- Use 0.2g's and hi/med caps. Spray the hell out of people.

CQB, w/ semi auto AEG/pistol/etc.- Use 0.25g's for that added extra accuracy and reassurance that you'll hit.

Open, e.g. Woodland, where wind and range are main attributes, any AEG at 100m/s or 330fps should really use 0.25g's or 0.28g's for that little extra range and accuracy.

Open, Woodland, Marksman/DMR/Sniper- As heavy as you like. I'd recommend some 0.3g's or 0.36g's.

But I only worked out the best from trialing BBs. Ask to borrow some when you next skirmish! Find a weight you like then, if you can afford to, try out brands!
Anyhow, good luck!

Re: Heavier BB's accuracy

hmmm.
heavy ammo + elongated v2 gearbox = energy creep.
Energy "creep" is a generic watered down term for higher energy transfer due to pressure build up.
due to the round traveling down the barrel slightly slower it gets the full amount of air behind it and it increases acceleration
so this means that
fps w/
.2 = 330
.25 = 340
(AA sa80)
is that breaking the rules?
because all weapons must be chronoed on .2s
