My coils don't kick in right away I am using 22g and 6/7 wraps battery's are fully charged and cleaned my points but still no joy

What battery are you using and what is your resistance? Depending on your resistance of the coil and your battery and it's limits . It might not have enough power to run the build.

That`s a really low ohm coil. Peeps is right, your battery may not have the amp reserve to push it, but it could stress your battery out and go BOOM!
What's the diameter of what you're wrapping the coil(s) around? Is it dual coil? Do you know the overall resistance of the build? What kind of battery are you using? What kind of rda? What kind of mod?
But, if I had to guess, I'd say you're using a lot of 22 gauge wire and that's why your coils are requiring too long to heat up.

2.5 mm ish is the diameter it's a dual cool round 0.3 ohms I think

Making your own coils really requires at least a half-decent mod and you need to take into account the maximum power of that mod. Coiling with anything under 24-26 gauge demands a powerful mod or mechanical and a very good battery. In general, anything else than a Sony VTC-4 or 5 is not recommendable for high amperage output. The lower the gauge of the wire you are using, the longer it will take to warm up and cool down. Avoid mechanicals if you don't understand Ohm's law properly,
Most people start coiling with 28 gauge and around 5 wraps for an average coil resistance of 1.3-1.5 ohms. The resistance will also vary depending on the coil diameter.
EDIT: 0.3 ohms dual coil with 22 gauge will need a LOT of power. You're really pushing the limit to the danger zone.

Tbh my thinking the smaller the wire the faster it heats up

The thinner the wire the faster it heats up. 22 gauge is THICK, so it will take time to heat up.
You still didn't say what battery you are using. Brand, model, mah, amp?

That diameter is way too big for 22 gauge. I wrap my 22gauge at 1.6mm or 1/16th. I can run duals like this and they fire fast. But IMO you need to move your gauge up a few notches. You have neglected to tell us what the resistance is of the coils are. Saying around .3 isnt going to cut it. Get an ohm reader if you plan on subohming that low so we dont have to worry about you hurting yourself or someone else for that fact.
I ordered one this week so I 100% know what the ohms are not just using my vamo

Good thing! But back to your main concern. The 22 gauge is really thick and it takes a while to ramp up those coils unless the diameter of them is very small (micro). This also means that you have to wrap more coils to pick the resistance up or else your resistance will be really low. I would suggest going up to 26 gauge. If your resistance isnt low enoug for you with duals at 26 gauge, you can always run them parallel. But be patient and wait for your ohm reader first.
Just a FYI, that battery is actually a 20 amp battery, not 35. Efest puts the "pulse" amp rating on the battery, not the more accepted maximum continuous discharge rating. Purple Efest Batteries Not As Advertised
0.3 ohm, and you really don't know for sure since you haven't measured it properly, is at the upper limit of a 20 amp battery.

Good posts. I agree with everything but the diameter being too big. IME larger wire needs a larger diameter on the wind to hold enough juice. This way the wick doesn't go dry mid pull.
What you need to be concerned with is wire length. This means less winds on the coil as the diameter increases.
@ 2.5 mm on 22 gauge I would shoot for 4 wraps and single coil... especially with that rebranded LG HE2 cell.
I run duals @ 24 gauge @ 3mm @ 4 wraps and they work just fine. Ramp up instantly.

A lot of new batteries coming out now. I just got a couple of Efan 40A (max discharge rate) They are also 20A current but are labeled 40A.
I posted a thread on those ones. Look just like the Efest purple marked 35A

Read, read, read on battery safety, Ohm's law, subohming and do some research on batteries, the vendor you want to buy it from (many many battery clones out there now) and your mod (many clones as well) before subohming. I recommend to everyone to start in the higher 0.7 to 1 ohm range while studying for lower ohm builds. You might even find that you can't even vape that low yet... subohming is often an acquired taste.
The only really safe batteries you can't go wrong with for low subohming are the Sony VTC4 and VTC5
Battery safety can never be stressed enough and low subohming can be much like shorting a battery out if you don't have the right combination.
