I'm glad I am stocked up on all my ammo and even got stocked on all my Reloading supplies, but my little family shoots a bunch. It's just my Daughter, Girlfriend and myself and my Girlfriend will pick up ammo if she sees a good deal, so I am very VERY Blessed. I haven't bought ammo since February and we haven't slowed down on shooting. I will however slow down a bit before I go out and buy ammo at the retarded ass prices now or be contributing to this B.S "ammo shortage". Have a wonderful day, stay safe! 🤙🏼

They had problems because the powder manufacturer wasn't allowing the powder to dry before shipping because the military was wanting it too fast. It was designed for Afghanistan, I was issued it and can tell you it did stabilize. I didn't in USAF guys with A1 uppers and SOCOM issued slower twist barrels that were old stock after SOCOM crossleveled a ton of guys in 2009 - 2010. It was explained to me by the L3 rep who was our sme on the ground at Bagram. We also had problems with the SR25 and Mk4 scopes around the same time because SOCOM swelled to almost 3x it's normal size in 9 months. I have a couple mags that were tucked into my tough box by my team after I was wounded if you want a few rounds to test.

A few years ago I had started working up a 262 load, and though I didn't finish the full workup I had gotten to 23.9gr of Accurate 2460, which had the velocity I needed (2750) and good accuracy out of my SPR build (~0.6" group @ 100). One of these days real soon, I'm gonna start working my load up again.

I agree. This is what I'm in the middle of in my reloading currently. I'm up to 24.3 grains of CFE223 and the non-cannelure 77SMKs. So far the accuracy is hovering around an inch for five shots. I may up them a few tenths but not until I run them through my chronograph. I have a batch of Varget loaded as well but have had a fit trying to find an opportunity to hit the range and test the Varget loads.

Thor's Axe777 Quantico is a US MARINE CORPS base. I was stationed there, I also shot on the base rifle team. If memory serves me correctly the Marine Corps Rifle team received Black Hills ammo and broke the rounds down weighed everything individual and reassembled into matching lots. Bullet weight, charge weight, case weight. At least that's what they did in 99-02. Capitol letters--not yellin just tellin haha Hoorah

I saw something on maybe the History Channel, years ago back when they did actual history shows, and they were showing a marksmanship team (don't remember what they were officially called) attached to either the Army or the Marines. They may have been your boys! They would sort the bullets according to variations in weight from the manufacturing process and then stick them all together so that each box contained projectiles that had the *exact* same weight. (They also made/customized their own barrels in addition to ammunition if I recall correctly.) Crazy. I hope to be a good enough shot one day where I can notice a .1 gram difference in weight of a ~168 grain bullet shot at a target 500 yards away. Shit, except under very particular circumstances I probably can't tell a difference accuracy-wise between a 62 grain and a 75 grain .223. The variations in my own groups are greater than the difference in point of impact at the close ranges I shoot at. Ah well. Some day. Maybe. Hopefully.

I think you're right in the assumption that the Black Hills is using the Nosler 77gr. I have both Nosler and SMK 77gr bullets and I just went and weighed and measured. The Noslers are exactly like your Black Hills: 0.996" and all weighed 76.9-77.0 The SMK 77s measured 1.010 to 1.015 and they all weighed 77.0 to 77.2 Ive had good MK262 cloning results with TAC, BL-C2, IMR 8208 and believe it or not H335...and I wouldn't worry about blowing your face off. Most all blow ups are due to obstructions. Getting 2750FPS out of a 18-20" barrel isn't too hard I personally like using hornadys 75gr bthp or Noslers 77 bthp over the SMK because of expense. The 75gr Hornady is a superb bullet and you can get them for a good price. I get outstanding accuracy with it using IMR 8208

Just getting one thing at a time helps build confidence in what pieces of info you have and then you start putting them together. Once you get good at putting them together you can start experimenting and it snowballs from there. It's really satisfying to build up your own rounds and it's kind of hard to go back, especially with how much money you save.

Great Video Johnny. I have been loading Sierra 77gr HPBT with great success ahead of 24.0gr Varget and 22.7gr TAC. The velocities 2726FPS and 2725FPS. The accuracy was MOA with me shooting which probably put in the most amount of variation. 24.8gr of TAC produced 2908FPS but the groups opened up. These loads were worked up using a Windam 1/7 chrome barrel but WOA 20" produces MOA or subMOA groupls depending on the shooter. As economical 77gr load, I am going to try the Nosler 77gr and TAC combination in the near future. WOA barrels rule!

I shoot it in US Service Rifle Competition from a match conditioned AR-15 A2, which has a 1/7 twist match grade barrel. I get an average muzzle velocity of 2750 fps. Groups are sub MOA at 100 yards, prone and iron sights. I use the load for 100, 200, and 300 yard events. The loading helped me to finish my quest for Distinguished Rifleman Badge.

Glad you did this exercise. I went through the same thing and have XXXX's of home brew MK262 Mod 1s. The pseudo-cannelure is Sierra. Nosler cannelure is real cannelure. Dr. Corbin, who makes the cannelure tools says it is not a good cannelure unless the cutter wheel rim is impressed into the brass forming circular lines above and below the teeth. Rumor was Sierra did not want to risk ruining the high quality of their OTM, by wrecking it with a deep cannelure, which infuriated the Army. I am pretty sure that the primer is CCI #41s which are specified in other places by the military to minimize slam fires in the ARs. My mystery powder is IMR 8208 XBR.

Primers used were tula small rifle magnum and winchester WSR. No crazy pressure signs. Primers seemed to flatten just a bit...on some of the rounds...I was shooting on a day that the temp was around 36-40 degrees @ about 2000ft elevation. Needless to say i was shocked because with all that said...the grouping was very good and consistent over 10 rounds. I would not rule out TAC as being the powder that they used.

One thing I'm concerned about is that I'm hoping I didn't make a mistake by going with the CMV QPQ as opposed to the stainless! I've heard they are great barrels but haven't seen the proof in the pudding yet. I'm really liking that White Oak barrel you picked up, that was in my top 3 list when I ended up going with this one.

You should be including Brass cost in your price estimates, the Marine Corp Service rifle/High-power Competitors often use the 262mod1 and the pressure reached by it makes the brass pretty unusable. They literally couldn't give their brass away at the Western Creedmore Cup matches in Phoenix, AZ or at Camp Perry the one time I made it up there as guys didn't want to risk only getting a load or two more out of them before separation issues start happening. (Flattened primers were common to see during the match from their brass on "mild" mid Oct Phoenix temps of 80-90F...) I used CFE233 to good results with all my handholds for competition in 69 and 77's and didn't have the pressure issues, but I never chased the 262mod1 velocities. Good luck and careful with your brass and face....

You sure like to have lots of projects going on at the same time. Do you have any plans to do 277 wolverine down the road? I decided to try and put an ar upper together for the first time and am going to try and work up some of my own loads for it. keep up the good work.

With Hornady Frontier Ammunition loading theirs with 75gr BTHP Match 5.56 at 9.99 a box of 20, i think they have a good option for those looking for similar performance from this caliber off the shelf.

I believe Black Hills used Vihtavouri for this load. N540 is suggested for heavy bullets but 25.5 gr of N140 should get you real close too.

I went ahead and loaded up some 77 gr. Nosler Custom Competition with 24.3, 24.1 and 23.9 grains of CFE223. I only have a 16" FN barrel from PSA but I figure I'll give it a shot. I have not been able to find the NCC 77gr. with a cannuler. I'll shoot them Friday if we do not get this rain from the storm in Texas.

25 gr. of Accurate 2520 and you are welcome, lol! I've been duping this load for years with 2520. Quickload is off a bit here. Max load data from Accurate is 25.5, with 62,500 psi pressure.

Great video as always. This inspired me to look through my stock of .223/5.56 brass to find any of the Lake City brass that I may have. After sorting through it and finding what seemed like 50K pieces of Aguila brass, I now have a pretty good stock of LC brass to follow along with. That being said, how do you follow this up with at scale review after getting me all excited about this load?

It has been mentioned here and everywhere, MANY times, how match type bullets have an irregular tip. We all know the bullet base is much more important than the tip, but it would be interesting to test what, if any, accuracy difference "wonky tips" make. How about making up a jig to trim the tips perfectly straight and square, and test them against irregular tips??

I don't know about your experience, Johnny but my leftover Black Hills brass was complete junk! I lost a significant amount of neck tension and the primer pockets swelled up beyond serviceability. Alliant has Power Pro 2000MR, which was formulated for heavier bullets, without putting pressures at dangerous levels.

I load 77grn Sierra's for my 18" 1:8 using W748. I use 24.1 grains and achieve 2650fps with a Wylde chamber and zero signs of pressure. My Lyman manual (49th) shows that as being max. 2275 fps from my 10.5" SBR if anyone is interested. I noticed you had listed 23.6 grains as max from your Quickload. I had also tested 23.9 grains on that same session @2490 fps. Maybe you should double check the 23.6 as max.

The boss man has stated the powder in Mod-1 is a proprietary blend. The best us mortals will be able to do is duplicate velocity paying little or no attention to all the other powder variables requested by SOCOM.
