Lower energy arrow weight for Sevr 1.75

[flyboy214]

Assumptions:
- These are not giant corn-fed midwestern deer. I will only hunt deer or turkeys with this arrow.
- Bow setup is an RX-7 ultra drawing 28.5 inches and 62 lbs.
- I regularly pass shots on deer if the angle is not ideal. I usually get rewarded with a chip shot later.
- My aimpoint for broadside or quartering away angles is lower 1/3 of the chest in line with the opposite leg.
- I have killed deer out to 59 yards with my old bow setup (stinger 4 blade on 460 gr arrows).
- All broadhead blades will be touched up and stropped.
- I will shoot 125 grain Sevr 1.75 ( purchased a bunch on sale).
- the Sevr FAQ recommends a 60 lbs compound for their 2.0 cut, but does not mention arrow weight.

Please comment to add data points if you are having success with 2.0 inch 2-blade mechanicals and pulling 65 lbs or less.
-comment with results, broadhead, draw length, draw weight, and arrow weight.

Sonic with a collar, skip the brass there's no point in adding weight without strength. Fyi the new Easton 5.0 that is coming out that is a little lighter than the Axis.

Hit me up if you need anything I do custom builds.

Using the Sevr 2.0 at 27” draw and 67# draw weight, with a 410gr arrow I did not have pass-through on the three deer I shot with with them, but the blades completely ravaged the lungs and the longest runner was 60yds. The first was 35yds broadside. The second was 22yds slight quarter away, and the 3rd was 11yds from the top down through one lung and the h half the heart. Given the damage they did, I wouldn’t hesitate to use them again. Although I’m going to try the Megameat next year for comparison.

Here's some food for thought. I wrote this previously based on not getting a pass through with a 1.5. My vote is skip the 1.75 and do a 2.0 or 1.5 hybrid.

Let's look at @Bowhuntr64 John Lusk's data on the penetration of these 3 mechanicals to see what we can learn. As you can see in the below table - the Sevr 1.5 does penetrate more. However, the gain in penetration over the 1.75 in PT1 is zero and only 5% in PT2 - effectively no loss in penetration for 17% more cut. The 2.0 loses only 8-9% over the 1.5 while gaining 33% more cut size. These tests John does in cardboard and gel typically give a disadvantage to more surface area - so logically the losses shown from 1.5 to 2.0 are actually over stated in his tests.

My takeaway on this data is that if you're going to blow your energy load with a mechanical on a whitetail, antelope or mule deer - you might as well go full size 2.0 Sevr or eq and get the benefit.

RX7 at 62lbs and 28.5 draw is not really low energy set up!

I have had many pass throughs with virtually identical specs, all the way down to a 360 grain arrow.

I think right around 400 grains is the sweet spot for stand hunting, so either sonic would be my choice.

I would expect any of those arrows to work just fine.

And your pass thru hits were ribs and lung hits with a 2 in mech?

I don't expect to zip right through the scapula and shoulder blade with the sevr 1.75 like I did with the magnus stinger.

The practice feature, amazing flight profile and slick locking design made me Curious enough to try the sevr.

My uncle has killed 200+ deer with between 60 and 70 lbs and wasp jackhammer 3 blades. So if I wasn't trying to reinvent the wheel I'd just use that. I think he shoots 450-480 grains usually.

Yeah no heavy bones and mostly whitetail does.

I’ve punched the ulmer edge through the scapula of three mature bucks, no pass through but buried to off side.

Ulmer edge is basically the original sevr if you weren’t familiar, those three with with 450 grains from what I remember.
