Have been diligently practicing with my WARF with 36lb limbs for just over a month. Can consistently hit vitals area out to 25yds 90% of the time with 10% shots being low at longer distance. 20yds and under I am at almost 100% and if I miss I usually can figure out why or what I did wrong (lack of concentration, dropping bow immediately no follow through etc..) sooooooo I want to move up to hunting weight 45 or 50lbs limbs. How much will this effect the trajectory of my arrows? I bought my arrows a bit overspined so I would not have to replace them when I moved up in weight. Shooting gamegetters 500's at full length with 125grain tips right now and get good straight flight, no porpoising. What should I look for moving up in weight?

The trajectory will of course be lower than with the 36# limbs.
But it is very difficult to tell.
You have things like drawlength, total weight of arrow etc.
since you are shooting a warf, are you then using a plunger?

If so you can probably use the same arrows, but it seems that you might get a little underspine.

but for a 45@28 I think your in the zone.

Whenever you make a change, you need to recheck your setup for good arrow flight; and retune as necessary.  If you have good flight now and increase your bow weight 10-15 pounds, I'd guess you will probably need to make some adjustments in the way of shortening your arrows, reducing point weight, or going to a heavier spined shaft.  Trajectory may be flatter to some degree (but not necessarily if you change to a heavier shaft), and you'll need to practice long enough with your new setup to recalibrate that computer between your ears.

yeah I am right at 28DL and flipper rest.

If your shooting the same grains per pound on the bow your trajectory will be about the same as you go up in weight.

If you go to a faster limb it will flatten somewhat.

Trust your instinctive ability to account for any added draw or arrow weight. Usually can account for any difference within 10 minutes.

Trad archery is much like throwing a ball. Baseballs & softballs are different size & weights; but, you don't have trouble throwing them. Same with the bow & arrow.

If you do have a change in trajectory your brain will quickly adjust after a few practice sessions just make sure you are still tuned and arrows are not to light when going up to that weight with the same arrows.

Thanks, now to find some limbs LOL. Hopefully some pop up used on the classifieds.

The change you experience will only amount to a few inches at normal hunting ranges. You will adapt to that very quickly.
