What are everyone's opinions/experiences on arrow weights?

409-422gr has worked fine for me.

A grain weight isn't really a important measure. KE, M and associated speed are more relevant. For example - a 400 grain arrow at 240 fps is a completely different animal than the same weight at 285 fps from two different people.

Focus on having the right broadhead for your specifications. And the right velocity for your desired range. If you have a lot of KE you can push a less efficient but maybe larger head through. Less KE focus more on broadhead design with higher penetration ability.

I personally like a rule of thumb like a 400 grain minimum for durability and a max 300 fps. Mabne 295 fps. Meaning you can't sacrifice arrow durability and get too light and when an arrow starts getting too fast it's less forgiving. Especially with fixed blades. There's always outliers though.

I have a 30" draw and pull 70+# for elk. Penetration at the KE & M level just isn't a concern. Even at 28" 60# and a modern compound you should have zero issues with a decent broadhead.

I follow the Ashby Bowhunter Foundation recommendations for hunting arrows. Their recommendations are based on actual animal testing.

I like 430 grains or so on the lighter side and 500 grains on the heavy side. My current arrow is 482 grains. 73# 28” draw. Go right through elk. I may drop down to 450 grains this year since the new lighter Easton FMJ’s came out.

With modern bows you don’t need to follow the Ashby method. To each their own but you don’t need a 600gr arrow and a huge cut on contact spear point broadhead to get a pass through or penetrate enough to hit the vitals on an elk.

A 450gr arrow that paper tunes good and most 3 blade fixed broadheads will do the job inside of 60 yards everytime at just about every angle other than the Texas heart shot.

I match my arrow and bow to what I consider best for my shooting style. I usually draw 75# with multiple bows. I build my arrows so that I have at least 13-15% FOC to ensure good momentum carries to target. My total arrow weight fluctuates a little depending on which bow I'm shooting. Let's just use my Mathews V3 31 at 75# I shoot a 4mm victory VAP SS it leaves the bow at 280 fps and weighs in at 490 grains with a cut on contact 125 grn fixed blade broad head. This set up is at a little over 15% FOC but has very little drag and great trajectory. I do not have to worry about vertical obstruction from 0-40 yards in the timber which is one of the most critical factors for me. It penetrates better than any other arrow I have shot from this bow and is extremely tough. I've had pass through on all the elk I have shot with this set up. When I build arrows for any bow I look at these factors and that is how I decide.

Solid advice here. I'm a fan of my setup with a 3 blade at 445 grains, moving 294 fps. Which is on the higher end of speed I like with fixed.

I’ve killed elk with 390 grain out of a slow Mathews Switchback up to 480 grains out of recent bows. 6mm, 5mm and 4mm shafts fixed and hypodermics and all did the same.

Best formula is quality head and heaviest arrow to ~280 fps

When I started to get interested in elk bowhunting, many years ago, and I was searching all the information I could find at that time, on an archery specialized forum and other internet sources (that's all I could do at that time, being located in Europe), it seemed that the concensus was a rather heavy arrow recommandation for elk, like a minimum of 500 grains and up.
Today I get the impression that the new concensus is more around 450 grains, with lots of successful elk hunters even using lighter arrows weighing between 400 and 450 grains.
The better understanding of bow tuning, better efficiency, faster bows, better arrows, etc, probably accounts for this move towards a lighter weight arrow for elk.

After seeing somewhere over 60 elk shot with an arrow from 360g to mid 500g there are a couple key takeaways for me;

Compound bows have energy to burn, An arrow of any weight from them is a dang killing machine

Match your BH to your arrow. If you are shooting a big inefficient BH, these function better with a little more weight behind them [mid 400g and up]. The very efficient COC BH's penetrate effortlessly and work well on any arrow.


A stiffer arrow is better than a noodly arrow

Perfect arrow flight is THE key factor....a slight wobble wrecks an arrows effectiveness.

 

[Skerhunter]

The high FOC craze and pod casts/social media kind of muddied the waters. Arrow weight is only part of the equation and there is no one perfect weight for elk. Properly spined/tuned arrow just depends on draw weight and length.

Lots of good advice on here!

There are a lot of things out there to read, watch, ot listen to, that muddy the waters. I listen to my shoulder talking. I passed on 2 or 3 popular brand, 60# bows, before I found one that didn’t hurt my shoulder, when drawing. My arrow total weight is 424, with 100 gr broadhead, and gets complete pass thru on bull elk at 30 yards. I have no idea what the speed is.

Interesting! Mind sharing what bows you shot and why you picked the one you did?

I wouldn't say that first part is a 100% absolute. Most people think the Ashby stuff is only about a 600gr arrow and EFOC. There are 12 factors they outline. The first two are arguably the most important, that's why they are "the first two". 1. Structural Integrity 2. Arrow Flight.

A lot of the issues I see and work on are #2, arrow flight, which you referenced in your second part. Paper tuning is part of it, but isn't the "be all end all".
