Gauges for various aas

Well i was just on spotinjections.com and saw the various gauges that they recommend for different sites, but was wondering if anyone knows of a list or thread that maybe talks about which aas can pass through which gauge easily. I'm sure there are other factors as well, such as oil and etc. Thanks for any info.

most oil can be shoot with 25g. you can draw with a 22g to make it easy and then chang to a 25 or 23g to shoot.

i currently draw and shoot with a 23g. so dar have only done ass shots. getting ready to do delts here shortly. gotta work up the nerve. then pecs. we'll see how dealts go 1st.
