so quick numbers show me this for my set up. currently 376 gr arrow giving me .45 MO and 62# of KE if I move up to a 420 gr arrow I would be around .48 MO and 63# KE would there be any reason to go up to 420 gr? any real advantage? going up any further and I start getting negative returns...
I hear ya. I also keep reading about getting to at least a 400 gr arrow for hunting with 60lbs. going up to 420 I would lose about 15 fps. and only gain minimal KE and MO... short draw length does hurt me.
I prefer heavy arrows with high FOC...I like the pack the best punch not the fastest. What negative returns do you mean would exist if you go to 420gr?
above 420 I begin losing MO and KE and speed. not enough draw weight/length to push that heavy of an arrow I guess.
Hold on OP let me figure it out. If you want a heavier arrow get a heavier arrow. The 15fps seconds lost is almost nothing and will make no difference at all.
the 15 fs is not the issue, if i lose that and gain KE/MO then I am for it, but if it is going to do nothing then I guess it's no advantage?? Maybe make my bow a little quieter?
Personally I hope to someday spend the cash on the tapered high FOC Alaskan BowCompany arrows and get at least the 200gr heads offered by them. Bone crushing penetration and the difference made in my normal shots from 15 to 35 yards is going to be minimal...if I cannot handle it I should probably stop bowhunting. I will say though I'm a Midwestern guy...most of my set ups (except a few) are shots much over 35 yards even possible or planned for....if I were like say Dustin Decroo from Wyoming (BHOD) I would probably stick closer to what I have now which is heavy to some but still plenty light for just a tick more flatter trajectory as shot chances are longer hunting open terrain features like present out there. But...I'm personally of the mindset I want to blow through a deer if at all possible...ribs should stand no chance of stopping a pass through IMO and a second hole will always leave a better blood trail than if my arrow only does one.
This is definitely a nice benefit of a heavier arrow, but wasn't the decision behind my choice to go heavier....cherry on top type thing.
yes, but In my case it may be the only benefit. and my bow is already pretty quiet. I never even thought about KE or MO until this year when I went to 60 lbs and Rage 2 blade heads. I shot and killed a deer saturday and hit a bit forward at 12 yards and it went thru the first shoulder and stopped when it hit the second shoulder breaking it but not punching through. Deer tried to run but only made it 30 yds and died within 5 seconds. I believe it would have put two holes in the deer if I was a little further back and /or maybe a bit more KE/MO.
I'm not sure why you think you're going to lose momentum by going increasing your arrow weight by 46 grains. You'd have to add a LOT of weight before you reach the point of diminishing return in the momentum department. You said you shoot 376 grain arrows now and your KE and MO are 62/45 respectively. I had to play with the calculator to get the numbers close and that was at 243 fps. Assuming that is right (or close) below is what that calculator says will happen if you increase to 420 grains and you lose 15 fps. You would lose a tiny, insignificant fraction of your current KE but you would gain MO. Assuming you lose 15 fps for every 46 grains you add, your numbers would be: 61.09 KE / .503 MO for a 466 grain arrow moving at 243 fps 59.09 KE / .518 MO for a 512 grain arrow moving at 228 fps 56 KE / .526 MO for a 556 grain arrow moving at 213 fps In short, you could increase to a 556 grain arrow and only lose 6 pounds of KE and you'd see a huge gain in momentum. Of course, you don't want to go that heavy, but the O N L Y things you're going to lose by going with a 420 grain arrow is a few fps and an insignificant smidge of KE.

Force kills not speed, I buried a 470gr arrow 10 inches into the dirt this weekend at 25 yards after blowing through a doe. If you aren’t shooting far than speed has very little impact on success Sent from my iPhone using Bowhunting.com Forums
I will sacrifice a little bit of speed for a harder hitting arrow, especially when using an expandable like a Rage.
Going up your momentum is more Important then KE for example I shoot 505 grains at 24% FOC with .56 slug of momentum and around 73 ft lbs of KE but my slug at 100 yards is only .529 so barely anything lost. Heavy arrows carry momentum longer Sent from my iPhone using Bowhunting.com Forums
Already heard of 2 stories where an expandable..will not specify...couldn't even make it through a rib...a rib. I am not an expandable fan, but a rib my friends should be blown through every single time. Arrow set up is wrong most often with penetration problems not the choice in head...but if I were using an expandable (especially large diameter) I 100% agree...I'm loading up higher on weight and FOC.
well it looks like going up to 400-420 is a win win deal... so littlechief, that bump in MO is significant?
