Cool! The 41 is really blowing the doors off of people's expectations! Im currently building a Savage Axis that I will be posting videos about, but a friend of mine was talking about possibly building an AR 15 in the 41. I'll let him know what you have going on. Thanks! Keep up the good work!
The 41 GL is the most impressive round I've ever seen perform in the AR-15 platform outside of precision long distance rounds. I'm very excited to be part of this project. I'm sure your Axis will be the best performing deer rifle you've ever owned.
All I and most deer hunters in the midwest want to know is if the brass case is UNDER 1.8" or not Then its legal to use in most if not all midwest states to deer hunt with Now if you can just get Ruger, Savage and CVA to make bolt rifles chambered in it Right now my public land deer cartridge is the 450BM I can push a 240grn Bear Creek copper bullet at an MV of 2550fps and my 245 grain Hornaday Interlocks at 2450fps but still only a 300 yard deer rifle. Will hope a reputable bolt gun company offers a model in this caliber soon Unless someone is manufacturing an AR upper or rifle am thinking reloading dies aren't yet available either Use Hornaday Custom Grade reloading dies for my HG and all straight wall rifle cartridges excellent quality dies
@@arthurdirindinjr1792 Yes the case is less than 1.8". My company is manufacturing uppers now and coming out with a bolt action in 2025. Idk if you know how long the 450 Bushmaster was out before Ruger picked them up, but I can say this. It will be a while before a budget rifle comes out. That being said my partners who designed the round have presented this to Ruger, CVA, Savage, etc. We figure if Obsidian Rifle Works can sell enough rifles it will show those big companies how much interest there is in the round.
@@arthurdirindinjr1792 Also Lee is making the dies for the 41 GL. Check out the Facebook page 41 Great Lakes Shooters to learn about the companies involved and how to continue.
Great question: Here in lower MI we're not only restricted to straight wall cartridges, but those cartridges must fit within specific parameters such as OAL cannot exceed 1.80" which means we can't use the 444, 45-70, or a host of other historically excellent rounds. In this video I just compared the most utilized/popular rounds in lower MI. Gotta love how regulated/restricted our freedoms are.
Of the "straight wall compliant" options, 350L and 41GL seem to have the principle advantage of component commonality with the .223 and .308. And should we want anything else? They're cartridges created by legislation, they should be made as little of a burden on manufacturing as possible. What lives by legislation, dies by legislation. 350L added value by bringing new powder capacity to the .378 rim diameter, 450L didn't and is actually less performant than it's parent .284. 400Legend is just in the weeds compatiblity wise; who cares about sharing a rim with the 6.8SPC? The 6.8SPC failed in it's mission, the military didn't adopt it, the .224Valk didn't take off. That rim diameter barely has any presence and creates additional component dimensions which ultimately mean rifle manufacturers need a whole new gun, not just a new barrel. I really hope 350L and 41GL are the future of this segment, so that a working guy can just spin on their pre-fit barrel for hunting season and be done with it, not buy a whole new gun.
As of yet Douglas barrels is manufacturing the custom barrels for all 41 GL rifles. If you contact them you should be able to get a barrel for your current bolt gun. We're making the AR barrels currently, and working on the 700 barrels for the future.
I didn't tell people for a long time, but the information is out there now. Parent case is a 30-06. If you'd like to learn more, there's a Facebook group dedicated to the round called 41 Great Lakes Shooters. Check it out.
That was significantly higher than what I expected as well. I guess the guys should post a video with the dynamometer for comparison. This does depend on which rifle platform, muzzle device, and ammunition utilized obviously.
With the energy levels you expressed for the various bullets, it sounds like it’ll be capable for more than just deer, at reasonable ranges. Possibly a wonder cartridge that might find favor with hunters doing hog eradication in states with those issues. No doubt it would be good for bears, too. Looking forward to more updates. P.S. Ron Spomer had a short video recently touting this new cartridge. He seems impressed with it.
Would you say the 450 feels like 10-15 lbs of recoil? If so, that's because the standard butt pad is 4"-4.5". This recoil measurement is taken per square inch. If you were to take 40 lbs divide by 4 inches = 10 pounds of felt recoil. We're talking specific 1" measurements of recoil. If you could please engineer a better, more accurate way to measure recoil. I'd love to test it, and will recant my statement if your device proves me wrong.
That's a great idea! I'd love to see the ballistic performance. Please load up those 150gr, shoot it on a chronograph, and tag us in the video. I'd love to see the data. If you're handloading the 360 you should get better performance than factory loads. I'm basing our data off factory loads of the 360, and so far they all fall short.
Check out Gabe's testing of a few different 41 GL loads: th-cam.com/video/W7tlhocqmAU/w-d-xo.html Compare the velocities on the video to what Remington lists as their velocities for similar weight rounds: www.remington.com/360buckhammer.html If you do the math to figure out energy difference between the 41 and the 360 you'll see the performance difference.
The 225 Gr Fury projectile, BC .210 @ 2,475 matches the energy out at 400 yards. It's not apples and apples because we're talking a straightwall vs necked magnum, but it's outstanding nonetheless.
@@ObsidianRifleWorks I calculated every factory Hornady load they offer in 7 Rem mag and its not even close in energy at any distance.. The .41GL is slightly better than a factory loaded 450BM 250gr @2200fps. Hopefully in time we will see better bullets and loads for it, but its to close to the 450BM to really care tbh.
That's great insight. While standard commercial 41 cal projectiles are for pistol loads, we use 41 cal rifle projectiles manufactured by several different companies to maintain performance out to 400 yards. You're absolutely correct that using pistol projectiles at those distances is at best questionable. Check out Gabe's testing of a few different loads: th-cam.com/video/W7tlhocqmAU/w-d-xo.html
Absolutely correct! The Pro Staff hunters in MI have been using this round for 4 years now, and a few have reached out to 550 yards. While I don't advise the typical hunter to attempt this, the energy is still capable out to that range, the drop is just insane.

Was the 444 not considered because it doesn't reach out far enough?

Can' wait to try it. When will this be available?
Heavily discounted Pre-orders are available now at obsidianrifleworks.com, the uppers will hit the shelves in January, not including the discount.
40-60 lbs of felt recoil on the 450 BM? Negative.
That was significantly higher than what I expected as well. I guess the guys should post a video with the dynamometer for comparison. This does depend on which rifle platform, muzzle device, and ammunition utilized obviously.

Absolutely more than a deer round. It's taken everything North America and Africa has to offer (hasn't been attempted on an elephant).
Make 375 great again!
OMG, do not give Gatehouse a run for his your money, he will be dribbling all over how his (insert cartridge here) is the 'Real King' !!
Wait, whadya say? 450bm 40-60lbs felt recoil and 350 has 5.5 to 6.5lbs? Nah… error!

360 buck hammer walks all over 41 gl
Load the 360 with 150gr projectiles and then compare. 😂

wow
Straight wall cartridges are low performance & exceptionally boring. I’ll keep them in wheelguns & pistols.
In many states it’s the only cartridge allowed for deer season.
Out perform a 7mm Mag out to 400 yards? Yeaa ok, with a BC of .21? 😑
Yea that's a pile of bullshit!
I didn't believe it at first either, but if you take the velocity, projectile weights, and do the math...numbers don't lie.
@@ObsidianRifleWorks Im curious to what projectile weight, bc and velocity was used for your math? I would love to be wrong.
The 225 Gr Fury projectile, BC .210 @ 2,475 matches the energy out at 400 yards. It's not apples and apples because we're talking a straightwall vs necked magnum, but it's outstanding nonetheless.
