Anyone confirm the nosler AB 210gr long range is .661 B.C.? Using 300 win mag. Thanks

Talks to much at open. Get to the meat…….

Or you could get an aftermarket shorter bayonet or alternatively cut the center out of your existing bayonet and weld it back together to make it shorter and fit on the arcangle stock

I had just bought a 590A1 the other day, went shooting today and had a hard time feeding. Thought it just wanted to play rough. But after a while I knew something was up. Followed your advice. Had burrs on both parts, which I filed down. Had to bend my one bar because it was too far away from the guide bars. Haven't shot it yet, but it seems to feed 100% better than before. I'll have to test it out and report back. Mossberg should have made the angled ramp longer or changed how it was actuated.

Others have commented on an adapter from Defender Tactical that allows the 500 series of mossbergs to reliably cycle mini shells and standard length shells. Defender Tactical now also offers an elevator with a longer tongue like you asked about towards the end of the video.

Now do G7

Wow. This video is total shit

whoooe, lots of talk talk talk. When does the bullshit stop and you start talking about "Ballistic Coefficient Explained start ?

The MIL version is nice and clean, the MOA version is very low resolution and not really editable. Do you have a high res version of it? Thank You!!

I don't have a 590 but another semi shotgun with a mag feed and same issue differnet parts. Would some grease along with your fix help the issue and solve the metal on metal contact?

I just use #1 buck with with pretty much the same powder and charge

In comparing various factory rounds, I hadn't realised that the projectile weight is baked into the G1 BC. The ballistics calculator that I was using (Hornady) has an input for bullet weight, and that makes no sense. Maybe the ballistic calculator has some other features I haven't explored yet. (or something). Now I understand why larger calibres with heavier bullets generally have much higher G1 BC numbers. I'll have to get the formula and learn how to calculate it myself (or right a program that gives more tailored tables).

To add one other note and prevent this from happening again. Have a look at the initial contact between the 2 pieces and bend the piece that holds the shells in the magazine back a hair and make sure that the initial contact is somewhat around 50/50. Mine was contacting at the tips of the angle causing it to blunt over the ends

tapco is garbage i put my gun in the tapco stock and it doesnt even fit and needs modifications which is GARBAGE

This is a fantastic video. Really helped a lot. Thanks!

Muito útil. Muito obrigado!

Great video but what a stupid flaw to have on such a "reliable gun" used the gun twice, maybe 70 shots total and already having this issue....

For anyone trying to visualize BC to understand it there is a simple demonstration I devised when I was an instructor . Take a sheet of A4 paper and try to throw it across a room . It will be very inaccurate and unpredictable . Now scrunch that paper up into a tight ball . It's still the same weight and the same material , it's just changed shape . Throw that and you can easily see the difference . The tight ball of paper can be said to have a better BC .

does it still work well?

... the new doppler based chronographs which measure bullet velocity at multiple ranges for each shot should be able to calculate the effective BC of the specific bullet being tested

I think I’ll just stay with the original wood stock…GEEZ!

How can i get a copy of your charts and doe you have ones for up to 20 mph? Thanks

Must check the results from the Olympics to see what guns won.

Have you seen the “Smith & Wesson Opsol Mini Clip 2.0 Flex For Mossbergs” I ordered on to help feed the mini shells.

Donde puedo comprar un rifle como este

A real simple demonstration of BC is to take a sheet of A4 paper and try and throw it across a room . Se how accurately you can throw it and how consistently it travels in the air . Now take that sheet and crunch it up into a tight ball and throw that across the room . instantly you will see the difference . Both Projectiles are the same weight and the same material but the crunched up ball has the better aerodynamic shape and therefor the higher BC .

DO NOT BUY THIS!! mine broke, the pins suck. You have to fish for the flash hole, primers go everywhere, huge mess, ZERO customer service, all sales final I tossed mine in the trash 🗑 Get the Frankfort tool( half the cost), or a lee decapper on a lee hand held press which is just

Defender Tactical kit is the best kit for mini shells for mossberg, have one for my 590A1 and it cycles every shell flawlessly

Gosh, both shot terrible

Great video! Had the same issue with my 590. All fixed now!

That was excellent, thank you.

fud... mounts are backwards, cmon man!

Such a great vid ... Thanks

Very interesting... and easy to understand the somewhat confusing Science of Ballistic-Coefficient.

Glad I found this little nugget

I wonder if it will interface with the autotrickler V4 or the new ingenuity precision system. I use a V4 with the ingenuity trickler. And the A&D120 scale. Always drifting and overcharging. I don’t know if it’s a response timing thing or programming but I’m ready to change scales and this looks like the best value. Any thoughts? Thanks for a great video.

Worked like a charm, Have a brand new 590A1 maybe put 200 shells through it. It had trouble feeding from the tube the first time i took it out, feeds better now that it ever has. Thanks!

Very cool. I do a .457 Round ball load in my .45-70 for similar purpose. ;) Kills ground hogs dead nicely.

Here’s a clip of the MP .311 Sledgehammer being fired from an airforce texan air rifle. 30 Cal AirRifle Vs .223 Reduced Load ruclips.net/video/myWYeUqY9zo/видео.html

I love low power .308 loads with cast projectiles. I have a .311 MP sledgehammer 140 mold that includes three different mold pins for a small, large cavities or solid nose. The large cavity hp will expand at velocities as low as 900 fps (air rifle) or performs well at 1800 fps with minor fragmentation. The video below is using little over six grains of W231. It produces low 1200 fps. The video also shows expansion. ruclips.net/video/9PWSlczdhAQ/видео.htmlsi=bCEBb7KMYJGwBdi4

Anschutz 54 shooting as 2+ inch group??? More data, different ammo and a number of shooters to provide a better study. This is a junk test. I own 2 Anschutz rifles and they shoot 1 ragged hole at 50 meters al day long with Eley match ammo. You'll never see a Bergara in the Olympics for good reason.

Stick with the original wood.

Any issues with the scale fluctuating and or errors.

👉💯👍

Nice video. So it's been a few years now, how have these magazines worked out? I'm looking at doing same modification to shoot heavies in a 22-204 cartridge, loaded to abut 2.620" OAL.

Nice video! Bring back the pretty lady at the intro and ending of your videos!

The number on the box is NOT marketing; the number correlates to the bullet profile under a controlled environment. When you're evaluating performance in real world settings, those values will obviously shift, but it's a reference point because you can account for different environmental conditions.

This is more of a personal preference than practical placement. Doing it your way would require training and a significant compromise to the effectiveness of the red dot, for a minor gain in target acquisition. If it works for you, then that's great, but a 45° offset is not much slower and you achieve greater field of view.

Excellent video.
