can I make that work out of a 45 pound longbow?
-
depending on how much weight you put up front
you may be able to
i always used them for 55-60 # recurves cut to 30 in i draw 29 and used 125 grain and 145 grain tips
i think if you put 250 grains or more up front you may be ok
i am sure that someone that knows a lot more than i do will be along shortly

You would be better with a 1816 or 1916,you could get it to work if left long a load up the front end.But you will likely end up with a 2018 weighing around 600+ grains.A 29" 2018 with a 125 gr. point weighs around 525 grains.

Ditto what JRY said. I'm shootin 2018's outta the 45#'er and the 53#'er equally well. Cut to 30.5 and 31.5, weighing 555gr. and 570gr. with 140 up front. Keep them long and load them up and you'll be fine.

Mo Hunting, I shoot a 2018 30 1/4 125 gr fp at 49 lb. Shoots great. If you are shooting a shorter shaft, I would go to 2016, or use 100 gr points.
-
a 2013 is a better choice if you want to shoot arrows that weight 430-470 grains.if you want to shoot heavier arrows go with the 2016 cut to minumin length and more point weight.robert :thumbsup: :coffee:

you should try looking at the easton arrow spine chart then work from there!!!
-
i shoot 2018s out of a 44# hoyt gamemaster 2 cut 30.5"=525grs complete with point and i use a 27.5" 2018 out of a 52# hoyt gamemaster 2...total weight is 475 grs. they can seem slow but they have accounted for a few hogs...and thats with the 44# bow.

These charts are inaccurate at best and not helpful at all as far as picking the right arrow the first time. This is especially true with traditional equipment.
I shoot 2016 and 2018 31" w/125 and 145 grn heads out of 45-53# bows they shoot great from recurves to longbows. I like 2018's for hunting because of the added weight. Tough arrows!!!

I was going to post about this as I'm in a similar situation. Might as well bring the thread back up.
I use a 2018 with a 125g tip cut to 31". I draw to 30".
I have been shooting them out of a 40# Pearson recurve - but recently bought an identical bow that is 45#.
Should I bump the tips up to 145 when shooting the 45# bow or will I be okay?
-
145's will weaken the spine. I personally would prefer 2016's, but my arrows are cut to 27 5/8 or 28. I use the same arrows for almost all my trad shooting, just change the weight up front.
-
2018 cut to 30 in. with 145 -165 tip will work out of a 45 lb bow if thats what you want . I do think 1916 or 2016 cut to 29 in. with 125- 145 tip would be the best arrow for a 45 lb bow but the 2018 will work fine .

So I should either be shooting the 125s or a 100 even. Only one way to find out - I'll get the bow to the range next week and see how it handles the 2018s.

This is my setup.
I have a 66", Blacktail Elite TD recurve. It's 42# @ 30" and it's cut 3/16" past center. It loves a 32" cut to back of point, Easton Camo Hunter 2215 with a 210 grain point tip weight. My arrow is fletched with three, 5" RW parabolic feathers set at 120 degrees between each feather with eleven degrees of right twist. My total arrow weight is around 614 grains which comes to 14.6 grains per pound. Flies fast, straight like a dart and hits where I look. This arrow really wallops a target butt. I'll be buying some 2 blade glue on Tusker 190 Concorde BHs and fit them to a 11/32" Zwickey 36 grain long broadhead adapter and after sharpening, I figure I'll be close to 210 grains tip weight. Oddly enough, there isn't much drop in this heavy arrow at 20 yards since the 2215 is a medium weight shaft at 10.7 grains per inch. I shoot with a tab and shoot off the shelf. My nock set on the bowstring is set at 9/16" high off the shelf. My bowstring is Dyna97, but I don't know how many strands or loops. I''ll have to ask Norm Johnson how many strands and loops when I talk to him next since he's building a second Blacktail Elite TD for me. I tried a 2018 with different point weights from 125-210 grains, but it just didn't fly well.

I can shoot 2018's out of my 60# revurve with a 125gr tip. 29"
-
2018s here for a 60# Hill bow. Cut 29", 145gr points.

First of all, Easton's chart is not inaccurate, we use it inaccurately. The chart shows the actual deflection at 28", with a 1.94# weight.
There's nothing inaccurate about that. When we read it we need to understand how to apply it to our bows.
Now, if your bow is cut at or past center, you can use a little heavier spine than those that are not. If you use an elevated rest, you can sometimes use a wider variety of spines. The bottom line is a 2018 has a deflection of .420 at 28" length. That puts it in the 60+ poundage range for a 28" arrow. You would need to add a good bit of front weight, "unless" your longbow is cut past centershot.
Spines, and spine charts, are simply a starting point, and have always been such. There are so many variables that create dynamics in a bow that one must try different spines to see what the bow will tolerate. Example: I have a 42#, 1961 Bear Polar, 66" AMO length. I have an elevated rest on it and a TS-1 string. I shoot 28", 2016 arrows from it, 125/130 grain points with perfect flight. They should be too stiff by the chart....470 deflection.
Take five guys, with the same bow/weight/length of draw, stand them side by side, and they will struggle to be able to shoot the same arrow effectively. Individual dynamics will turn those into five different bows. The human equation.
One thing I like about archery is the individualism that is required. There is no "black and white" chart that will fit everyone. Same with brace height....same with nock height...same with string type and strand numbers.
Try the 2018. They will probably be too stiff. If you don't want an ultra-heavy arrow then you will probably need to get into a 1916. Or, a 2016 with maybe 160 grains up front. You see you are the one who will dictate what that bow will shoot, and you are the one who needs to experiment. Personally, I think a 2018 loaded up front is going to be on the line of dimishing returns. You have to decide, however.

Thanks george and the gang. My dad gave me a whole box of them he found new at a garage sale for not much. I have a couple good arrow combonations that I shoot now. I just wondered what poundage they are good for. I just recently got my hands on a easton spine chart. Like I said I have a couple winning arrow combos now. I will prolly find somebody some day to trade them for some more 1916s. Now they are just setting in my garage. Thanks guys.
