Rifle Compensators Compared

Cool article at The Truth About Guns:

http://www.thetruthaboutguns.com/2014/11/jeremy-s/556-muzzle-device-shootout/

#1 is the Precision Armament M4-72 Comp ($89)

#2 is the JP Tank Brake

#3 is the venerable Miculek comp

Missing in the article are the JP Bennie Coolie, SJC Titan and Rolling Thunder brakes. The Liberty Mystic Suppressor comes in middle of the pack, verifying my observations that a suppressor/silencer is not as effective as an actual muzzle brake/comp.

3gun, Frostproof, 11-22-14

Open Division:

• S&W-JP 15: Meopta, Sightmark offset, Fiocchi 55 gr and Fiocchi and PPU 69gr ammo
• Open G34 – 147gr BB FN ammo
• Saiga – Federal and Winchester 3DRAM and Fiocchi low recoil slugs

Stage 2

• Rifle + pistol, IPSC rules (can’t leave the shooting area): go out and back, shooting with rifle, return to beginning, then 1 shot strong hand with rifle in weak hand on a plate
• Rifle seemed ok until I was told of 2 FTNs. Short range rifle, these are easy hits. I’ll blame lack of practice.
• Strong hand with pistol failed; I quit after 3 tries. Need to practice strong hand with the Open 34.

Stage 3

• After the debacle of that stage, I decide to just go first at every stage.
• Start with shotgun on 8 steel, with the last being an activator for an array of 4 rolling downhill.
• 1 FTN on the last of the rolling array.

Stage 4

• All shotgun with 2 slugs (select drill). I plan out the mag loading so slugs are where I need them in my shoot plan.
• I do as I planned, but could have gone better without the dud round (no jam, just no fire).

Stage 5

• First run is a disaster as I miss a target and again give up on a piece of far steel. Time isn’t recorded so I am mercifully given a re-shoot.
• On the re-shoot, I perform my original plan of tripping the port door early and taking some target prone, instead of running back and forth.
• Clean.

Stage 6

• Saiga runs fine (the last malfunction was ammo, and not the gun), steel is one for one.
• Paper is clean, thanks to shooting the quick swinger with more than the required 2 shots.

Stage 1

• 100-150yd steel, mostly off-hand.
• Fatigue set in near the end, holding the heavy rifle off-hand. Practice with the MP15-22 is good with off-hand shooting, but it doesn’t replicate the same feel and weight.
• Not the fastest, but not the worst.

Not my best work, but I’m out of practice. It’s amazing how missing a weekend of shooting can affect performance. That and not getting enough sleep. At least it identifies weaknesses.

 

147gr 9mm and Longshot or Titegroup

Quick note on a future load with 147gr BB FN and Longshot:

Start: 3.8gr LS, 1.100OAL – 850fps; right at minor pf floor

Max: 4.7gr

Why Longshot? It’s not really recommended for 9, but I have a whole lot. It’s slow burning – #52 compared to Titegroup (14), WST (18 – current), WSF (36), and Power Pistol (33). It’s mainly for the Open 34, which may soon get a comp – even for minor – as this article shows:

http://www.shootingtimes.com/gunsmithing/reducing-recoil-traditional-vs-bushing-compensators/

But in the same article, it shows some reduction even with the use of Titegroup. Not as high as the best performer Accurate #7 – ranked #50 on the burn chart (hence the choice for Longshot), but still showing 38% reduction.Or maybe I should also just use Titegroup, something I have a lot of as well? And I don’t need to worry about non-compensated guns.

Start: 3.2gr TG, 1.100OAL – 855fps; right at minor pf floor

We’ll see…

3Gun, Manatee, 11-8-14

Open Division

• SW-JP15, Meopta primary, Sightmark secondary, Freedom Munitions and Fiocchi 55gr ammo
• Saiga 12, Winchester and Federal (blue box) 3DRAM ammo
• Open G34, 147gr BB FN ammo

Stage 1

• 50-200 yd steel, from low ‘barricade. The barricade wasn’t as solid as I thought, so I took a few too many extra shots, also from the second position/barricade a few yards up.
• Target engagement sequence was dictated, which I thought was unusual.
• Too many makeups on steel with the pistol.
• 3rd

Stage 2

• Offset dot for the close target, then 4x on the Meopta for the far head shot. Again, engagement was dictated: 2 to the body, 1 to the head; close to far. 4 mikes on 3 headshots, and 1 body shot. Need to work on this drill with the 22 – 2 to the body, 1 to the head, using reduced targets with the 22.
• Again, too many extras on steel with the pistol. I realize I miss shooting the Open Edge.
• 16th

Stage 3

• From behind the barricade, with the rifle, for 4 ‘amoebas’ on the left, and 3 on the right. Meopta on 1 x. While trying to go fast, I settle on a constant rhythm versus 2 quick shots. Dat-Dat-Dat-Dat, vs DatDat – DatDat – DatDat.
• Steel with pistol and I realize the shots are high, so I aim low and the hits come easier. Need to re-zero the pistol.
• 7th

Stage 4

• Offset dot for the “2 to the body, 1 to the head” paper (again) with the rifle. This time I pepper the targets for insurance; on the move. Clean.
• A few shots with the pistol on steel, with some on the move, using the offset I learned from Stage 3.
• Saiga runs well cleaning up the remaining steel.
• 3rd

Stage 5

• Cancelled because of a schedule conflict by the range.

Finished 4th overall.

USPSA Ruskin, 11-2-14

Open G34, 147gr BB FN rounds.

Stage 3

• Start at center, then mirror left and right, all up close, all open. Hose ’em up.
• 10th. 2 seconds off the pace of 1st, and down points because of minor scoring.

Stage 4

• Stage 3 modified to only the insides; more of the same.
• 10th, 2 seconds off, points on par.

Stage 5 

• L – shaped, with 1 far target at the top of the L. Walk down the line for some on the side, then some more at the base of the L.
• A shooter from the previous squad shared the tip of his 2 sweet spots. I shared the info with the squad as well. I ran through the plan but decided to shoot the course on the move instead – continuously shooting as I walked the L. I get to practice shooting on the move at medium to far targets. Ok, maybe not shoot the far ones on the move, but I’ve resolved to practice shooting on the move and to choose to shoot a course on the move when possible.
• 1 mike; no biggie.
• 12th, and my time was actually better (just by a few seconds) than someone who ran it using the sweet spots.

Stage 6 – Classifier: Tick-Tock

• 4 around the clock surrounding a no-shoot. I start at 3 so the no-shoot is last.
• 13th.

Stage 1

• More on the move shooting, but splits could stand to be faster.
• I shot the furthest target 5 times – 3 the first time, then I re-engaged. On the move didn’t work for the no-shoot and that far target. I should’ve shot the open target on the move first, stopped, then taken the far open and no-shoot target last.
• 7th.

Stage 2

• Big poppers with an array 3 no-shoots surrounding 2 paper, and a half target behind them. Big disaster factor.
• A buddy said: “it’s gonna suck”. I thought to myself that he’d already given by saying that — and he’s a great shooter!
• Big poppers go down 1 for 1, and to mitigate the no-shoots, I go for the heads. Unfortunately, I only get 1 in on each. The half target is good.
• 28th

Finished 10th overall out of 47. Keep doing what I’m doing, and add when possible:

• dryfire for dot acquisition on the draw
• range time with Bill drills for splits, and dot torture for accuracy, or small plates at 15-20 yards, also for accuracy
