Good idea #728.3

After having gotten a good look at the M-Lok attachment standard, it occurs to me that handgun makers should be abandoning the trend of putting Picatinny rails on pistols, and adopting M-Lok slots on them instead. 

They look less obtrusive.  If you don't want to rail anything on your pistol today, the slots won't get in the way, and will more cleanly conform to holsters, compared to the Pic. 

And tomorrow, if you want to put the weapon light or the laser on your 1911's dustcover, you can.  And when that doesn't work out the way you had hoped, the accessory comes back off and the pistol returns to its original envelope. 

The accessories themselves would be a bit lighter and less clumsy too. 

A 1911 or Gloock dustcover with slots would be barely noticeably larger than a dustcover with no doodads at all.  Best if these slots were blind so all the junk in the world will not pass through them and interfere with the pistol's operation.  Or the pistol ships with rubber slugs for each slot, which pop out with a screwdriver. 

The standard slot seems to be about 32mm long, which could be hard to fit on a compact pistol.  Maybe an abbreviated slot length could be had, if the accessories' toggles were closer together to match. 

Hey Polymer80, get on this willya? 


Savage Scout 11FCM and MEN milsurp NATO ball

not bad.  Now I need to download some Android app that can measure a photo of a shot group and pull out the group size. 

This is a five-shot group at 60 yards.  Flyer lower left.  The rest of that ragged hole was cut by 4 bullets, not three.  The group was shot with no defined point to shoot at, just my attempt at "center of the paper plate" using a Vortex Crossfire II Scout set at 2.5 power.

the tears in the paper plate are from spalls thrown from Grendel bullets hitting steel about 6 feet away, lower left.  Ignore them.  There's a story behind that steel I was pounding with Grendel but that story is for sometime telling in September. 

Lest one think that there's another flyer hidden under the nickel, same plate with the nickel moved:

Ammunition is MEN military surplus, 147gr NATO ball, lot MEN16E0836.  That ammo was priced very attractively about 2 years ago.  Shots were 2583, 2598, 2602, 2602, and yes, 2602 fps.  PACT chrono.  The widest extreme edges of that group (hole at 12 to hole at 3 o'clock) come in just under .750". 


Stripper clips and guide for 6.5mm Grendel

The case head dimensions for the 6.5mm Grendel cartridge are close enough to those of the 7.62x45mm Czech that their stripper clips work.  7.62x39 clips won't because they're curved to follow the tapered case body.

One or two eBay sellers had the stripper clips.  They're 5-rounders.  For a 25-round magazine (C-Products in this photo), 5 clips fill it. 

The GG&G stripper clip guides for 5.56mm ammo can be modified to take the Czech stripper clips.  Bend outward slightly the rails that attach the guide to the magazine, bend outward a bit more the rails that hold the stripper clip to the guide.  Your mags will get a little scratched. 

The Czech clips have bumps that stop the clips from entering more than about .500" into the guide.  The first clip will strip into the mag OK but not following clips, because there's too much gap between the end of the clip and the top of the magazine.  The cartridges pile up instead of schmoozing on into the mag.

Your Dremel, with a cutting wheel, can carve open a slot on each side of the guide to let those bumps in so the clip seats deeply into the guide.  The slots need to be long enough so there is barely enough space for one cartridge case head between the top of the mag and the end of the clip.  The bottom round of the clip should be almost touching the follower.

The slots will be the width of about two thicknesses of cutting wheel, to accommodate the bumps.  See the red markup on the photo.  A needle file down the insides of the clip guide rails will help the clips to slide in squarely. 

Wirebrush the slots to clean up your work.  If you're obsessive, degrease the guide(s) and reparkerize or zotch them with teflon/moly.

I think a rub or two of paraffin on the clips themselves will help the cartridges slip out of them. 


reloading 5.56mm with CFE223 and 55gr FMJ----with update

Sounds kinda boring and vanilla, right?

Lake City never-fired pulldown cases, still have the Uncle Sugar primer.  I miked a pile of them for head-to-cone length and separated them into cases with .003" or less under nominal, and those with .004 or more under nominal, and used these shorter ones for this trial.

Generic 55 grain FMJ (Hornady?  IMI?  Milsurp?  can't remember) but they've been tumbled in molybdenum disulfide powder in a pill bottle for a few hours.

Hornady's manual, on the page for 5.56mm NATO instead of .223 or 5.56 Service Rifle, says CFE223 goes max at 27.6 grains  Hodgdon's site says 27.4.  With a 20" barrel, a startling 3200 fps. 

So I rolled 5 each starting there and going downward to 26.6 gr in .2gr increments, so I would start shooting them at the bottom of the charge weights and move up, stop at first pressure signs. 16" Bushmaster barrel.  I should be able to stretch 3050 fps out of that with 55 grainers, maybe? 

Nope.  2826fps. The bolt wasn't locking open until I shot the 27.4 grainers.  Cases come back out with HTC of about .002" over.

Feedback, people.  Meanwhile I'm pulling all that are left, and starting over. 

Update 20190201:  Small sample size, but 27.6gr yields 2834 fps.  27.8gr, 2865fps.  28.0gr the MV dips to 2862, 28.2gr @ 2916fps.

I'm moving back to WC844.

another wish list item

I've always gotten an adrenaline rush from ELP's "The Barbarian."

Since youngest Toad, now in excess of 6 vertical feet of stature, has joined his school's marching band, I suggested that somehow The Barbarian could be arranged for a marching band.  I can hear it in my mind's ear. 

While looking for a marching band arrangement, this you tu b came up.  Who knew that, yet again, ELP repurposed a classical piece as spaceman progrock?

These guys---3 Hungarians and a Usonan---knocked it the fuck out of the park. 


well we just sit around here

Midway 1292:  new motor from Grainger costs more than a new tumbler. 

New tumbler:  Amazon is undercutting MidwayUSA something sick. 

Amazon:  "hey why not stream some music from a bearded Justin Timberlake while you are sitting around in your house waiting for your tumbler?" 

Midway 1292 tumbler

It just blew up. 

I was cleaning up some 6.5 Grendel brass and some Lake City 7.62 after success at a range.  Stopped the tumbler to have a look, figured they needed a little more cowbell. 

I flicked the switch, and sparks jumped out from beneath the bowl, then smoke curled up from within. 

Motor is smoked.  It had a good run, I probably bought it in '92 or '93, before joining my Sainted Wife in matrimony. 

Though running it on the floor of a dusty garage might have hastened its demise.  

Maybe somebody has a replacement motor.
