I was told I couldn't bow hunt them with my current setup posted below. Does anyone agree not agree and do you have a setup recommend for me thanks for all advice
Dl 25"

I would check the regulations in the state you are planning to hunt. For example the minimum arrow length in Idaho is 24", that way you have a starting point for length. If you got a heavier GPI arrow, heavy insert and 125 gr broad head with a .400 or .350 spine you should be able to make it work. You might have to cut the .350 a little longer to soften the spine. What is your brace height and axle to axle? I can run a couple options through the OT app.

My brace height is 5" and axle to axle is 28

That's complete B/S. My wife is 27.5"/45lbs/325IBO and she's fine for elk, you are far above that.

Not much downside to having an extra long arrow (I prefer to keep broadhead away from my hand too). You will find different opinions on this, but majority here (And myself) think a heavy arrow is best for elk due to retained momentum.

Easy to reverse engineer it: aim for arrow 450+ grs (which would get you 259 ft/sec and 67 lbs of energy which is great according to http://backcountrybowhunting.com/calculator/). Figure out your arrow length (look at regs as mentioned), say a 26 inch arrow to make example easy. Looking at day six's spine chart (my personal favorite) and that puts you at a 350 spine w/ 125gr head or just at 400 w/ 100 gr head. Just add up all the numbers (shaft length * gpi, insert/outsert, point, wrap, vanes, nock etc) and figure out what puts you where you want to go. Day six HD, black eagle, easton (injexions or fmjs), gold tip (kinetic, possibly pierce), etc all make heavy GPI arrows 9-11+ grains you'd need to hit that 450 mark.

Then use a cut on contact broadhead (expandables use far more energy) with less width (1 1/4" or less) and fairly swept blades + bleeders so you get really good penetration. Some great suggestions are slick trick vipertricks, rocky mountain cutthroat, day six evos, iron wills if you're spendy (and don't mind maintenance), etc.

You're done! Nice solid arrow with plenty of energy and penetration to kill an elk every day of the week. Put a good shot in the right area and enjoy!

Looks like an Axis .340 cut to 25.5" 75gr insert and 125 gr broad head would put you at 475gr and the spine would be a little stiff, but it shouldn't be an issue. A set up along those lines should be fine depending on what you are wanting to build. There are a lot of folks on here who are much smarter with archery hopefully they'll chime in.

Thank you both this give me light at the end of the road.

OP, plenty od guys shooting through critters with low energy Stickbow setups. In fact, I've shot a couple hogs in the last 5 weeks with my 45# recurve....both arrows blew through and into the dirt so far I never found them .

Low energy setups benefit from a couple things; Heavier arrow weight....and a very efficient BH.

The heavier arrow absorbs more of your bows energy...and the efficient BH [tapered 2 or 3 blade cut on contact] maxes out penetration.

My elk setup is a 50# recurve with a 560 gr arrow COC BH....and you have a lot more potential energy than I do.....

I’d run as heavy an arrow as you’re comfortable with and let her rip
