Instructor’s takeaways from recent Guerrilla Sniper Course

[gregmanz]

While I can’t take a class, I can agree that suppressors make life easier but also make things dirty

That .300blk deflection is a lot, I know not to use that not

wonder what the deflection is using 110gr barnes bullets or similar solid copper supersonic 300 blackout.

I mostly run my suppressors on my bolt guns.

I bet it would be in between a 5.56 and a .308.

I run it on all of mine, find it to much more pleasurable. Less recoil and sound

I have a lot of gear to loan out for courses such as this, up to and including rifles and optics. Don’t let a shortage of kit keep you from the course.

If 2-3moa is the recommendation I think I got that covered as is.

Hell by Christmas I'm liable(trying actually) to have a bolt gun... thats the next buy. If the ODT show ever happens.

But yea thats why I'm asking this early. To know what I need to do and bring to get the most out of the course. Including more practice until then.

1. We shot through various types of residential double pane glass, with the target set approximately 12” behind the barrier. When shooting through automotive windshields, the distance to the target was from the windshield to the headrest of the front seats.

When shooting through different types of glass and polycarbonate, the general trend is that heavier is better. Students used a variety of 5.56/.223 loads with bullet weights that included 55grn, 62grn, 64grn, 69grn, 75grn, and 77grn. Additionally, I shot some Hornady TAP 5.56 70grn GMX Barrier Penetrator. The heavier bullets had less deflection from POA than the lighter bullets, regardless of bullet construction.

Within the same weight class, purpose-built bullets had less deflection. For instance, the Hornady TAP 55grn GMX Barrier Penetrator had less deflection than M193 ball, but not to a significant degree. A 77grn Sierra MatchKing, which is not an especially tough bullet, had less deflection than the 55grn TAP GMX, but similar deflection to the 70grn TAP GMX. The solid bullet design of the GMX aids slightly over the FMJ as they didn’t tumble or yaw, as the FMJ’s oftentimes did. You could tell on the residential glass that the softpoint rounds mushroomed. On the windshields, they either missed the target entirely, or we were unable to find the exact bullet hole due to so much spalling causing secondary projectiles. When the round mushrooms and makes a jagged hole, it’s difficult to tell from larger glass fragments. Clean holes and keyholes are much easier to locate.

A 168grn .308 had significantly less deflection on automotive windshields than a 140grn 6.5 Creedmoor. A 175grn .308 had slightly less deflection than the 168grn .308. I have some Federal Gold Medal Match .308 loaded with the Berger 185grn Juggernaut en route......very excited to see how it does. I am also curious as to what effect velocity has on the deviation. I plan on loading some 175grn .308’s at various velocities to see how the same projectile reacts at different speeds.

I made a few shots with a 16” .300Blk using 220grn subs. I don’t recommend it as a barrier round. For instance, after going through a 3/8”-1/2” sheet of curved polycarbonate (side door window out of a typical piece of earth moving equipment, like a dozer or skidsteer), the bullet deflected almost 4” and keyholed. This happened within 12” of exiting the poly.

2. Practice at shooting outside your comfort zone. That piece of readily available artificial support may not always be that perfect height. In all the time it takes to fiddle with it and make it perfect, or you going to miss the window to take your shot? Know your abilities and limitations. At the distance you are at, know how stable you need to be to make a certain shot. Unless you just want to be a recreational distance shooter, practice various standing and kneeling positions. Learn how to use a sling for support, even if it’s just a hasty sling.

3. Suppressors make life easier.

4. Doesn’t make a difference how accurate your rifle is if you’re having to clear a malfunction every 2-3 rounds. If you usually run your AR suppressed, you need to give some critical parts a cleaning now and again.

5. Make that first shot count. Steel targets are nice and patient, they’ll let you try that follow-up shot or two. Most critters, regardless of how many legs they have, will not.

6. Clear communications with your partner or team are critical. Two guys running around are twice as good as a guy by himself. Two guys that communicate and function as a team, however, are a million times better than a guy by himself.

7. For making precision or critical shots at distance, milsurp ball ammo ain’t your friend. Whatever ammo you choose, know what it is and how it behaves. It’s not good when the Instructor asks you what ammo you’re using and you can’t give the correct bullet weight.

8. It’s a good idea to both know how to dial your dope AND use your reticle for hold-offs. FFP scopes make things easier for hold-offs, but SFP’s will work as long as you’re at the correct power.

Semper Fi!

I don’t run a can on my 5.56 gas guns very often. If I were going to, I’d build one specifically for it. I spent 40 years of my life without a can, including my time in the Corps. I can do without one without a lot of heartache on my AR’s. I’ve gotten very used to having them on my bolt guns.

Are you finding the heavier bullets are more accurate in your .308? What rate is your rifling. My Bergara seems to prefer heavier .308 rounds, but the trend is toward match ammo in the 168 gr category, not hunting rounds.

Mine is a 1:8" twist.

Nowadays, there is a much larger selection of match ammo for .308's in the 175grn range than in the 168grn. Of course, with everyone buying up ammo, there may be a shortage of the 175grn as it tends to be the more popular of the two.

If you aren't handloading, try the 175grn-178grn loads from Federal, Black Hills, Hornady (their ELD loads are superb), and the IMI Razorcore line. Surplus M118LR/XM118LR is great stuff, as well, but I don't see it as much as I used to.

If you want to try out some 175grn loads and can't find any, let me know. I can either help you find them, or float you some of my stash.

I'll I've fired out of the Bergara so far are 175grn rounds. I bought a case of 185's, but haven't got to the range yet.

With a handload of mine that is a duplicate of the M118LR load, I usually put 5 rounds into .33MOA at 100yds, and shoot .5MOA or better at distances like 400-600yds. That rifle with that load has been run out to 1,000yds by one of my students with no issues at all.
