kk, this all sounds good! so when it comes to TB barrels (6.01), the BB's to use are:
1. Metal Tech MFG
2. KSC Perfet
3. BB Bastard?? or is this brand not good enough to use in a 6.01?

Those are good but anything from Japan are really good. They invented airsoft they know what's right and what's wrong

I have used all three of those in my tightbores with no problem. The one I have used the most is BB Bastard, but all three have worked fine for me.

Does anyone sell .23?

KSC perfects work in everything, flying colors work in my 6.03 but i wouldnt use them in a 6.01, and I dont know if it was just a real bad batch, but I tried metal techs in my M4 once and they were just shooting all over the place yet my KSC perfects shot real straight.

Go with KSC perfects.

.30's in a sniper. They're the most economical... (Cost wise Vs. Quality)

On the contrary. All of my products work well in tightbore barrels, which are also the only barrels I use in my own guns. You should get good results, particularly those running PTWs...

but do you use 6.01mm tightbores?

I used the KSC's for a few years and they were great untill I tryed using them in the PTW and I guess the Nozzel hits them too hard and you can see little chips in the hop up,so I just use AE's in the PTW and AE's and KSC's in the other AEG's.I like the two,but the AE's are,gummy is the only way I can think of describing them,and the KSC's shatter on impact where as the AE's crack.All my other units use Promethus 6.03 tight bores and the PTW is a 6.04.They all seem to work well depending on your set up.All thow I may have to try a new brand to see how they work lol.

KSC don't work in my CA SR-25 or in Systema's.

I use Airsoft Elites, they are just superb.

Retailers? BB Bastard?

No they dont, madbull does, check airsoftparts.ca

The only two BB's I've ever had jam my guns were airsoft elites and metaltechs, it's safe to say every gun differs in its taste for ammo...

After shooting around ten thousand rounds of BB Bastards in .25 and .28 I have never had a jam, with or without a tight bore barrel.
