I recently purchased a brand new PSE Bow Madness 34. IBO speed is 342. My draw length is 28.5" and I'm pulling back 65 pounds. Arrows are carbon express 350, and I shoot Muzzy broadheads - 3 blade fixed, 100 grains. I have a 3 pin sight, and was wondering what yardage others would sight the pins in at. Strictly hunting whitetail deer. I ask mostly because I used to shoot a PSE Bow Madness XS and wasn't comfortable beyond 30 yards with. This new bow is obviously much faster and I'm curious how other people would approach sighting it in.

That is a stiff arrow. How did it tune with field points? How did it broadhead tune?

Paper tuned and shooting bullet holes. But, I've only actually practiced with field tips so far. I'd like to get as dialed in as possible with field tips before I switch to broadheads.

CE has a newer rating chart DIY, CE 350 is what is called for with his rig at 65#'s and 28.5 length. Which CE's are you using wooden? Also which nochs and fletching as well as anything else to add in for weight. Need to know the total weight of the arrow to figure out an estimated speed. Even with my bows that throw a hunting rig at 320fps I still don't shoot past 40 yards on live game. Just my limit. If you are limiting yourself to 40 yards and have a relative speed of 300 to 310fps then I personally would set a 3 pin up to 20-30-40. From 0-20 the drop is negligible, from 20-30 the difference would only be around 2 -4 inches at best according to what fletchings you have and what setting you have them at, I.E. Straight, offset, helical. and then another 2-4 inches from 30-40 again according to your setup. One of my rigs I just use a single pin out to 40 yards. But that puppy smokes my hunting rigs out at 336fps with 1 degree offset fletch. with only 6 inches of drop from 0-40 and I know that setup like the back of my hand so I know my holdovers at 40 if needed.

Ive found that the CE estimator for what spine to use is too stiff for the guys that I assist and myself. CE says I should be using a 350 spine. I am a real stickler for these things. 350 was not the answer as the CE charts would lead a guy to think. Im getting great tears, and great broadhead flightwith fixed blades heads from point blank to 50 yards with 150's Mazima BLU RZ. If you were to believe the charts there is no way I should be able to do that. Broadhead tuning is where its at. Field points are too forgiving. Most guys have problems with broadhead flight because of too stiff an arrow so they think the charts are correct and they switch to mech or tiny heads to correct what is a spine issue.

Hmmmm, never had a problem with that myself. I paper tune as well as step back (pain in the butt) but I did just recently drop my poundage from 72 to 65 and haven't had the opportunity to tune in yet. Hopefully my 350's wont be too stiff. But if so, been looking for an excuse to get some new shafts to play with anyway Only problem with that is I still have 2 or 3 dozen of older CE hunters (pre maxima crap with all that FOC stuff) but I guess I'll have to bite the bullet and give them a try. Been using CE's since they first came out. Been a long standing dedicated user of their products.

The ONLY times I have ever encountered a problem that wasn't a tuning issue or the flight characteristics of a certain fixed broadhead was if that broadhead was really long. Changing the FOC. Since the mass is supposed to be the same, how can a broadhead cause a spine issue as long as it and the field point is the same weight. It's the weight of the tip creating the resistance to the forward motion created by the release of the string which is causing the dynamic flex in the arrow. If the mass= the same of both then from a math standpoint there should be absolutely no difference whatsoever. Only the FOC is differentiated.

Running the numbers through the bow speed calculator which I've found to be very accurate (http://backcountrybowhunting.com/articles/toolsOLD.php) and estimating your arrow weight to be 420 gr. (9.8 gpi x 29" plus insert and nock) I come up with a speed of 293 fps.
I don't think your 350s are too stiff. I had the same problem with my PSE DNA with almost the exact same set up as you 28.5" @ 63#. Shooting my 400s through the chrony I was getting 307 fps and it shot field tips very well. But I could not get my broadheads to match the field tip POI. I switched to 340s and all was well. A plus to using the 350s is they are slightly heavier giving you more KE.
As for sighting in - I'd sight my top pin for 20 yards. Then shoot at 30 and see where you hit. If the difference is minimal you can reset you pin for 30 and hold a bit low at 20. Now this is only if you have a multiple pin sight and plan on shooting at extreme distances as it should give you more spacing between you pins.
Good luck and enjoy.

Thanks for the feedback. Was thinking 20, 30, and 40 yards.

That will work fine.
