What's the difference between Black Hills 5.56x45mm NATO Ammo 77 Grain Open Tip Match and Black Hills MK262 MOD 1-C?

Wow black hills cheaping out with the hornagay bullets. Lame.

Just throw 77gr TMKs in there and send it.
Meh, if my recent testing and dealings with Sierra are any indication, hornady might be better. Don't waste your time with 95smk .22 or 7mm 183smk. Junk ass bullets that vary .030" oal or thin jacketed they come apart. Hard pass

@RAVAGE88 great idea placing the mag blocker as far rear as possible.
I considered this but didn’t know if pressure on the DBM would have any influence on accuracy.

One other thing to consider, and likely this is accomplished by the 3 different lengths of mag blockers you’ll offer.
Lots folks are using 3d printed mag extensions which are wider all around and will interfere with mag blocker unless given enough space. I thought there was something mentioned a few posts back that your blocker will interface via ARCA. Assuming that’s the case, the 1.5” will allow for clearance of the aforementioned.

Good stuff. Love the concept!

I don't know if this helps anyone.. but it might.


FWIW...Ogive OAL measured with a Hornady Bullet Comparator.

Blue Bullet , PSA / AAC 77gr OTM ( current production lot ) Pulled Bullet only Ogive OAL... .606".... actual OAL of bullet... .9825"
Green Bullet , Black Arc 77gr Horn. ( just received ) ......... Pulled Bullet only Ogive OAL.... .6045"...actual OAL of bullet... .988"
Red Bullet, BHA D556N9 ( current production lot ) ........... Pulled Bullet only Ogive OAL.... .607".....actual OAL of bullet... .987"
Pink Bullet, IMI 262... 77gr SMK ( Brown Box ) ............... Pulled Bullet only Ogive OAL.... .608".....actual OAL of bullet... .995"
Orange Bullet, BHA Mk262 Mod 1-C, 77gr SMK................ Pulled Bullet only Ogive OAL.... .6035"...actual OAL of bullet... .982"

BTW, Current Production IMI 77gr Razorcore... did not have a cannalure..... Pulled Bullet only Ogive OAL.... .595"....actual OAL of bullet.... .9785"

FWIW... I have no idea how much "margin" for error there is on cannalure or Bullet ogive placement, or the actual bullet OAL... but the alledged Hornady 77gr OTM, certainly has a narrower cannalure width, compared to the 77gr SMK

"Back Yard" testing with 24hr soaked, dripping wet newspaper, while not perfect... can be enlightening.

Having a burn pile helps getting rid of the soggy newspaper, Lol

I used to do a crap load of it , prior to Ballistic Gel / the internet being available.

What I am saying... is it was better then nothing.

One surprising "test", was comparing .357 Rem. 125gr SJHP to a 9MM Winc. 127gr +P+... both fired from a 2 1/2" Ruger SP101.

They both had very similar muzzle velocities, and bullet weights.... but the Rem. Scalloped Jacketed made a FAR more impressive wound cavity.

What that showed , was bullet design mattered.

While I wouldn't want to be shot with either load... the .357 bullet Scalloped but was going to mess some one up far more than the Winc. 127gr +P+.

Both penetrated the same... but since you could "peel" away the inches of newsprint, the difference was dramatic.

Soggy Newspaper was good enough to see which rounds could lose their jackets, or if the HP would clog up repeatedly.

We did a crap load of rifle rounds as well... all the way from .458 Lott - .223.

At the time, it was all we had.

It may not be as repeatable as modern ballistic gel.... but it sure showed us young men a lot.

MTG wakes up to the fact, taxes are nothing but legalized theft

Property taxes should be illegal. You think you own your home? You’re just leasing it from the .gov. Stop paying your property taxes and see who really owns it.
this is the 1st basic truth of taxation. you,or the bank,don't own it. the gov does. don't pay,they will take it. resist that and they will be happy to kill you. income tax is different. they take the $s before you even have a chance to not pay. they'd have to kill too many people if paying was done after you got the $s first. the tax code is made so complex that anybody with anything but a W-2 can't understand it and will always break some law that even CPAs don't know about. also,creates the $300/hr CPA crowd that many are forced to use. i do despite my simple and limited income. keeps somebody between me and the IRS that has a vested interest in knowing and following the rules.
of course the bottom line on all taxes is the lack of representation before they are levied. our "representatives" are all corrupt parts of the brute force system which we pay for. does anyone really believe that there is any substantive difference between the USA,the USSR,Nazi Germany? China is just ahead of the curve but palantir will help close the gap.

Henry SPD Hush vs Marlin Dark 1895

The Henry design is superior to the Marlin because if it jams you can release some pressure on the action by removing the magazine tube.

Superior to both the Henry and Marlin would be a Winchester (Miroku or Chiappa or Taylors and Co) 1886 Takedown model.

Having had two Marlins develop the “Marlin Jam,” which cannot be cleared without tools, I will never own a Marlin again. I view the Henry action design with the same distrust as the Marlin.

Winchester 1886 / 1892 / 1894 Takedown models all day for me.

7mm SAW

Have not had stellar results with the 145 lrx and Varget or h4350. Decided to stick with the 162 ELD M and X.

This mornings range report:
42.3 gr varget 2.25” bto was the ticket for both. .5-.6” group average.

2790 fps with the eldm
2820 gps with the eldx

22” barrel suppressed.
Alpha brass.
Little to no swipes on 42.3. 42.5 had 20 more fps and about equal group sizes, but was having more prominent ejector swipes on every round.
