2016 and 2018s

[Mryan2176]

I have a kodiak mag thats 45@28. Both 2018s and 2016s fly like darts. They are both cut at 29 inches with 175 grain fiield tips. How is it possible they are both bare shafting well at 20 yards? And the dilema, should i use the 2016s or 2018s ? The 2016s are 50 grains lighter. They weigh 524 the 2018s areabout 580. I'm leaning towards the 2016s , my only concern is getting pass throughs on big deer. The 2016s are gamegetters and are considerably cheaper in cost. Any of you guys hunting with the 500 gamegetters with a similar setup. I think i might be overthinking this, but i can't decide, thanks Matt

Can't tell you which you should use.  I assume you're concerned because they say they're spined for a 70-ish lb bow.  I shoot a 45 lb Shakespeare and 2018's are great.  If they both shoot well about the only difference I see is that a heavier arrow penetrates better (and costs more).  In the real world I'd say you're going to get pass throughs with either one, so, cheap guy that I am, I'd buy the cheaper arrows.

I would go with the 2018's for the extra weight which will give better penetration and the thicker walls of the shaft which makes them more durable.

Me too.

2016's are the 30/30 rifle round of aluminums. They have accounted for a lot of deer. Use them with confidence.

Yeah, only reason i tryed 2018s is because a buddy gave me a few he had lying around. I use stus calculator and the 2018s apparently have a dynamic spine of 61 pounds my bow requires a dynamic spine of 50. The 2016s are almost an exact match at 49.3. I know this is all based on theory, but it has worked like a magic 8 ball for me. Well until those 2018s shot so well. I'm starting to think the stick on rest is magic, ever since i put it on iit seems the k mag is twice as forgiving and now somehow arrows that should be too stiff fly like laser beams. So any way its worth the extra cash for the 2018s and 55 more grains you think?

The 2016's are 11.64 gpp for that bow and the 2018's are 12.88 gpp.  You have plenty of weight with either one.  If you already have the 2016's, that is what I would use.  No deer will be able to tell the difference after they zip through following a sharp broadhead.

If you look at the total of Stu's calculator it suggests that a personal form factor can also be an important ingredient in the recipe...I believe that super good form with consistent clean releases can compensate for some rather large deviation in spine...give yourself a pat on the back for great form and stop overthinking the whole situation...shoot the less expensive 2016's and spend the extra money on keeping your shooting skills sharp

When I am feeling kind of sloppy and need forgiving I will always pick up one of my 1960 Kodiaks with a featherrest...I generally shoot my bows off the shelf but all four of my Kodiaks have featherrests...one has one of Trap's excellent new designed rests and the other 3 are original...something surreal about shooting arrows off a 53 year old rest

I'd go with the 2018s because the thicker walls would help them to stand up to a little more abuse.

x2...

As always I like to preach flying straight is a more important factor with penetration than weight. Paper tune them and see which ones straighten up first and use it. I would want to use the 2016's. There is plenty of weight there. With your 45 pounds they will fly flatter also.

I shoot an older one piece martin saber and have a 29" draw, bow is rated at 45# at 28".  My arrows are 2016 gamegetters cut at 30" with 125grain tips. I have harvested quite a few deer with this setup using both 3 and 2 blade broadheads.  Not all my harvest have been pass throughs, but I do not expect 100% pass throughs.  What I do get is clean kills and very accurate shooting.

The only way I would not use the 2016's is if I used the 2018's. :^)  

 I don't think it will matter. Use whatever gives YOU the most confidence.
