Im going to a 40 LB bow. Just wondering if anyone shoots 1820's? I heard they are tough shafts.

40#, you might want to try a 1916, by buddy tried them out on his 40# and they were like darts. I use the 1916`s on a 38# too.

I bet the 1820`s are tough

Unless you have a long draw or leave the arrows long they would be fairly stiff.

I draw 27" and use them cut to 28" in bows that are 45-50# with 125 grain heads.

This is my group with a 50# Mamba with a low-stretch string at 22 yards.

They do hit hard and are tough!

At what arrow length. Kind of important.

Ahhh, the old hit hard statement. That's likely because they are 12.25 grains per inch, nearly identical to a 2018 in mass. So what is it you want? More mass will be quieter, most likely, and also slower. But at 40# they may likely be too stiff unless you are at 30" and draw a full 28". Depends on the bow as well, and the string....and centershot...and??????????

george, since I just got the bow Im not sure. But Im gessing minimum 29.5.

1916's

I have two main questions about these… First is whether you can use a standard size nock with the skinny arrows… (Or do you have to go to an extra skinny string to use the undersized nocks?)

And can you get RPS inserts for them so that you can use whatever point you want?

I just switched the small throat nocks and went to the large throat nocks and use the same string. And second question,yes they have RPS inserts so you can use whatever point you want.I just bought a bag of 100 from 3 Rivers.

looking at the 3r calculator 1916 might be a better option. But since this is a vintage bow Im tempted to go with wood.

1820's are one of my favorites. We have scads ofcthem around here and have used them for years.

One of the reasons folks get a weak indication is because of their small diameter. Like any other arrow shaft if you don't tune the bow and arrow together they shoot terrible.

1916's, 2016's and any other shaft or material will give you the same result if you don't tune for them.

I have never used 1820. I do used 1816 or 1916's out of my 40 lb longbow. they both fly great. I have them cut to28 & 1/4 with 125 gr.

Based on my actual experience using these arrows in a dozen different bows they would be too stiff for a 40# bow. I use 1816’s in 41-45# bows.

I use Deep-Six nocks as they are stronger and accept standard width strings.

Picture is a 52# Howatt Monterey with 28” 1820’s. I draw 27” so 50# at my draw. That’s good arrow flight.

I loved the idea of them but they are heavy in physical weight for what they spine, about #53 if I recall correctly. I couldn’t get them to tune off of bows over about #35 and therefore were pretty darn heavy for such a light bow. Plus I was paying extra for inserts and new nocks to fit my strings and by the time I did that the “value” in them fell behind more common arrows like 2016…

SM -

A full length 1820 spines to about 53#. Your call.

Viper out.

I don’t know how some of you guys do it but I do have a 30” draw and shoot a 30.5/31” arrow.

31” - 2016’s with 125gr point on my bear takedown 45lb@30” bare shaft weak.

I use 29” 1816’s out of my 40# bows. I draw 27”…they have always flown great for me.

I would think at a true 30 inches draw,45#s and a 30.5/31 inch long arrow you would show 2016s to be weak out of your Bear.

Those long arrows and your long draw make a big difference when comparing to a 28 inch draw and 29 inch arrow that alot of guys would be using 2016s successfully out of 45 # Bear T.Ds.

1816 or 1916

Guys -

Lets be clear. Sure and 1816 or a 1916 can "fly great" from a 40# bow, but only one will TUNE from that weight bow.

Then there's whole "tuning" debate.

Viper out.

I tried unsuccessfully to tune 1820’s from a 45 pound bow and I have a 30” draw. Would shoot ok with field points but broad heads were a disaster.
