C02 paranoia Purging cornies and bottles help

[newtonsshed]

Am I getting too hung up on having a bit of air in kegs/bottles or is it really needed? Like most I've syphoned off into fermenters, cornies & bottles but am now starting to look at ways to do it with minimal air being present and I quite like the look of the beer guns but not too sure how they work.

I have a kit bear that I'm going o knock up tomorrow and to ferment in a plastic narrow neck bucket initially will have top on with air lock until head forms. Once head established will loosen the top and ferment for 3-4 days once head subsides re seal with lid and leave to continue fermenting for 7 days or until slowed down I then plan to rack from the tap into a cornie via the beer out post on the keg. I will first purge the keg with C02 gas so lid be seated and sealed and hopefully under a blanket of C02, I have a couple of questions here;
1) Do I prime? It's a woodfords Admirals Reserve 5.5% abv at 32 pints fermentation before racking off into cornie to condition will be say 14 days in total.
If I do prime will this cause issues when purging?
Once I've purged the cormie do I release the safety valve to let the gas out or not?

Once I've got it in the cornie I plan to condition for 6 weeks - what temperature should I condition at? room or cellar and do I need to have it connected to gas or will the natural condition be ok?

Once matured in the cornie I plan to bottle, to do this I'm thinking straight from cornie via the beer out post and through one of those little bottler (plastic stick with a one way valve that is open when pushed to bottom of bottle and stops when lifted up)Am I right in saying the bottling gun is connected to C02 and the beer so you put a bit of c02 in to get the air out and then fill with beer and then cap? If so how do you stop air getting in between moving the temporary cap off and the crown cap on? Could you also make one yourself by getting a Y adapter one end to cornie and other to C02 and the other end into the bottle squeeze trigger for a bit of c02 and then allow beer in?

your right .you are getting to hung up on having a bit of air in kegs.

With cornie kegs, you can get (if you're not used to them) too hung up on the whole air Vs Co2 thing. Cornies are better when you force carbonate them. A constant supply of gas gas is better than a quick burst from a trigger. With that view in mind, you don't need any priming sugars whatsoever. The simple way forward for piece of mind is to pressure up to more than your serving pressure, say 20 psi, then burp it (release the pressure) which will expel surplus air. Pressure back up again to, say, 20 psi and leave. When your ready for connecting, connect, apply serving pressure and serve.

A G is vastly different from kits. With kits, you have to factor in the conditioning time. AG is around 2 weeks, Kits are (at best) 6 weeks,. This is where a conditioning bucket comes into its own and you try to drop as much yeast out of solution as possible prior to kegging.

The best train of thought is to treat the cornies as one massive bottle.
