Well lets start by saying im more of a compound person myself but id like to try and get my first kill with my recurve. I have an old recurve that is 45# at 28 inches. Im only drawing maybe 27 So its not the full 45#. When shooting at my target(reinhart 18-1) i only penetrate 4 or 5 inches into the target from 10-15 yards. Im worried that this may not be enough to kill a deer and i sure don't want to go out and wound one. So what do you all think? Would this penetration be sufficient enough to kill a deer or should i hold out and stick with the compund?

It should be about 42/43lb @ 27" so it is enough to take a deer just use a really sharp COC head on a heavy arrow, you might not get a complete pass through but it will get the job done if you do your part.

Besides what what mentioned, shot placement will be critical.

Of course as it is in compound hunting too. Im confident in my shooting ability as to im limiting myself to a 15 yard range at the max. What weight arrow would you suggest me to shoot and how long? and anything else i would need to know. Thanks

Of course, I just wouldn't crowd the shoulder very much.

Weight wise, I'd say between 420 and 500 grain will keep you on the normal 10-12 grain per inch category. I'd stay closer to the upper end if possible. Arrow length will depend on how they fly. Just like a compound the setup will need to be in tune.
