Easton 6MM Full Metal Jacket™ Carbon Shafts Review

Depending on your draw length I would recommend a 500 spine for that set up. The 175 grain point might be a touch on the heavy side.

It will depend on your draw length but tentatively a 500 spine should be right for you. I'm shooting a 64 inch spyder xl at 43 lbs. I have 175 gr up front and have tuned well with a 500 spine. 50 grains will make a difference in your spines, I would recommend a spine test kit before ordering arrows.

All of our arrows are measured from the valley of the nock to the end of the shaft.

I would recommend 9/32 in any weight you desire.

It looks like Eastons charts recommend a 320 spine. The nocks will be installed they are a press in style nock.

Looking at Eastons Charts they would recommend a 340 spine.

They look like a wrap but that is just a different color of the shaft. It has a silverish tinge to it.

390 I shoot a setup pretty close to yours

Dear Friend, I have limbs that bracket your 50lb (low 40's to upper-mid 50's), but my arrows are longer (31") and I typically use 250 gr heads. I shoot a border bow/limbs that packs a high amount of energy for the poundage. I suspect Blackwidow does as well, but I have no experience there. For my lowest limbs (probably around 43 lbs at my draw) I use 390's and 200 gr heads and they shoot good (though I don't use these limbs much). For my 49lb limbs I shoot 320 spine/200gr head. For my 56 lb (or so), I shoot 320 spine/250 gr heads. Keep in mind that my arrows are cut to 31 inches and wouldn't be quite as stiff as 29 inchers. These all shoot quite well out of my Border bow. I've always found that if I was to error I'd go with the heavier spine and then use heavier heads if needed. By the way, I also have an old (23 yrs old) Bob Lee (55lbs at my draw) that shoots these reasonably well, though without the same punch as my border. I also have a 52 lb ACS that doesn't shoot these well at all, but I think it has more to do with me and my mechanics with that particular bow (it just doesn't work for me for some reason). I only mention all these because sometimes your release, etc. will impact the spine that works best. I've included the link to Eastons chart below along my opinion of what I would choose, BUT FIRST I'd e-mail Blackwidow and get their opinion as I'm sure they'd be glad to help - they've always been helpful to me over the years for other things and I don't shoot Blackwidow bows (though I'd like to give one a whirl someday). The hunting selector chart from Easton would suggest that you use a 390 spine for your set up and that is likely where I would begin. https://eastonhunting.com/wp-content/uploads/2018/05/2018_Hunting-Shaft-Selector.pdf FMJ AND CARBON ARROW SELECTION CHART< https://eastonhunting.com/wp-content/uploads/2018/05/2018_Hunting-Shaft-Selector.pdf> eastonhunting.com FULL METAL JACKET Materials/Construction Inserts Points Nock System Nock Type Weight Tolerance 4 Straightness 1 Color/Finish Sizes 4MM FMJ INJEXION™ recision 775 alloy jacket Have a great day and happy shooting.
