  1. Same....2.9 grains under 147 Blue Bullet Truncated Cone with OAL at 1.115 135 PF BC
  2. You can save a bit of money on the pistol grip by going with Magpul or any other AR15 grip. Smoke Composites was selected as their stuff was used on my PCC and the owner provided a significant discount once he found out I was a USPSA and SCSA competitor. The parts selected went for the lightest weight possible along with a left side charging handle. Being on the left side also ment that the bolt had to come from the same company as the receiver (link) and it looks like they have increased the price up to $274.98 from $250. That was just a personal preference, being right-handed it was just easier at "make ready".... Another guy that was in my squad last weekend at a SC match had the same setup in black and said his father purchased it from Volquartsen (link to rifle) and their price is $1,769 without an optic. That one has a right side charging handle. BC
  3. Receiver & Bolt - $250 Barrel - $300 Trigger group - $273 Stock - $500 Grip - $180 Total - $1,503
  4. When first starting with an Open division gun in USPSA many, many years ago, one of the Master class shooters told me to push the gun, muzzle up toward the target, then rotate the wrists while focusing on the very top edge of the glass. The dot will drop right out of the top of the lense. Absolutely agree. Muscle memory required to push muzzle up and rotate wrists. BC
  5. Raccoon Hunters has a full set of them (and tablets) for the Steel Challenge matches and was using them for the USPSA matches. They were the first club in this area with them. Detroit Sportsmen's Congress has some on order now and they should be in when we go back outside. BC
  6. After a two month wait, the AMG Labs Challenger timer arrived. For Steel Challenge, this thing is really great. Well worth the money and the wait. The Bluetooth interface transfers each string time directly to the data entry screen in PractiScore. No more fat-finger errors or flipping the numbers around when dyslexia kicks in (lol). Headed out to the December SC match at Brooklyn Sportsmen's Club in Michigan with the timer and an Amazon Fire tablet running the latest version of PractiScore. After selecting "Enter Scores", a stage and a squad, there will be a little icon at the top of the screen that looks like an alarm clock. Press that and it will prompt to connect to a timer. If you are running multiple timers, you will have to determine the last 4 characters of the device (MAC) address which can be displayed on the timer. Select that four character code on the tablet's display and you are on your way. Things to be aware of: 1. The same alarm clock icon is now in the bottom right corner of the time entry screen. Before each shooter starts his string, make sure there is no "slash" mark through the icon as that indicates it is no longer connected to the timer. Just tap the icon and the Bluetooth connection is re-established. If you don't do this, you can still manually enter the time, just be aware of #2. 2. If you are entering a miss penalty and accidentally fat-finger bump the time (or have to manually enter it) the next time sent from the timer will not go into the correct string. It could overlay that already entered time or "jump" down to the incorrect string entry. Solution: Press next to the time, just to the right of the last number and it will be framed in gray. Leave it that way. Now you are ready for the next string. When the competitor starts firing, the tablet will move to the next data entry slot and start recording the time. 3. Sensitivity setting - If you turn it ALL the way up to 10, it will record the Range Officer TALKING. Remember, it functions on pressure changes, not sound. Running it at 8 picked up all the shots, even from the rim fire guns. Since it was in the high 20's to low 30's everyone on the squad really enjoyed keeping their gloves on and just visually checking the timer display (which is HUGE) to the tablet. Tremendous technology improvement, you just have to be aware of the above mentioned items. Thank you AMG Labs and EUXX for the PractiScore programming to make it all happen. BC
  7. Outer Impact (link) and Sig Romeo 3 XL (link) with the 3 MOA dot (aim small, miss small) mounted on the Performance Center version with the carbon fiber barrel and Tandemkross Gamechanger PRO comp. As mentioned, all the weight sits right in your hand. BC
  8. Currently using the back pocket but due to this thread, will resurrect the Open gun's magnet. The plastic chamber insert already has a metal ring attaching the "Remove Before Pew Pew" bright orange flag to it. My routine at U&SC is to slowly pull the charging handle back so the chambered round falls out the bottom of the magwell into my hand, place that round in the back pocket while pulling out the flag. With the flag magnetically held on my belt at the hip, should make the whole process much more efficient. Before the next stage, take the round out of my back pocket and put it in the Barney mag. Good to Go.... BC
  9. Ran into the same issue when shooting the PCC so switched to "in ear" protection. They are a bit on the pricey side but don't interfere with the stock. Have started in Steel Challenge with PCC and rimfire rifle and as Sarge said, not hearing all the correct stuff can be a bad thing, like the round dinging the steel. These were at a price point that was below other in-ear models, have a recharging case and Bluetooth integration to your phone for controls. Walker Silencer BT Amazon has them for less than the Walker website (link) BC
  10. Just started SC about 6 months ago in PCCO division as that used my existing carbine from USPSA competition. Load is Blue Bullets truncated cone 147's over 3.1 grains of VV N320 at 1.15 OAL. That combination made minor comfortably in the 16"' carbine so started using it in SC. Came across this topic and ordered some Bayou Bullets 105 gn FP and worked up a load that would cycle the carbine without changing out the recoil spring. 2.4 grains of VV N320 and seated the bullet into the case to a point where the "funnel" portion of the bullet just met the top of the case. IIRC the OAL was 1.08. Was very, very soft but have not loaded any more to test for accuracy. Will let you know when the weather warms up a bit and can spend some time on the outdoor range. BC
  11. Two incidents at our club during matches: 1 - Shot himself in the leg during the draw from a Serpa holster. For those not familiar with the Serpa, there is a "unlock" button on the holster to draw the gun. It lines up with the trigger. He pushed the button and kept the pressure on as the gun came out and his finger hits the trigger.... hard. .40 round went into the thigh, then out of the thigh and into the calf. Came to rest just below the skin after breaking the fibula bone. He was lucky that the ER was less than 2 miles from the range and we had a physician's assistant shooting the match. She took care of everything, including chasing the guy away that insisted he had a medical background and demanded she put a tourniquet on him. When she asked what type of medical training he had, he said "I sell durable medical equipment". When the EMT's arrived, they look over the situation and told her "Great job. There's nothing for us to do except load him up and drive." Serpa holsters are no longer allowed at the club for USPSA competition. 2 - Racegun went off during the draw. Round went into the dirt just to the right of the shooter's foot (it missed). He was so shaken up that after the "Stop" command followed by "Unload and Show Clear", he didn't. He shot the ground AGAIN about 2" to the right of the first bullet impact as he was trying to re-holster. Non-standard command of "WHOA" quickly followed.... BC
  12. Walker's Game Ear Silencer Earbuds Rechargeable - R600 These come with their own recharging case which will charge the earbuds about 6 times before it needs to be connected back to a power source. Very comfortable with 3 different size inserts. Comes with two replacement ear "hooks" (left and right). Bluetooth interface connects to an app on your phone to adjust settings (volume, auto-off, mode, etc.). When interfaced to your phone, you can hear incoming calls. Very handy when the phone is in your range bag and someone is calling. Much better version than the one that uses hearing aid batteries (have used both). BC
  13. Thanks George.... much appreciated. Just to be perfectly clear regarding what George stated in his last sentence: Sweeping or pointing the muzzle of a firearm at any part of any person’s body during the course of fire. If the firearm is in a case and not in the competitor’s hands, sweeping does not apply. Reaching forward of the muzzle of a cased firearm to close the case is not a sweeping infraction, provided the competitor’s hands are completely clear of the firearm itself. So if they come to the line with an unzipped case (they took the cased rifle to the safe area, unzipped it and put the chamber flag in, then didn't zip the case closed) then arrived on their first stage, should the RO instruct them to return to the Safe Area and zip the case? Cheers, BC
  14. Similar... For PCC, started out with 6 Glock mags, 10 in each and reloaded after each string. For me, it was a distraction. Switched to my ultra-dependable Glock 31 rounder with MBX extension on it and load 37 rounds. On the last run, I release the mag, check that there's more than enough rounds left in it, re-seat it and run the last string. Not changing magazines keeps me further in the "zone". Shot my best times in that division using this method. On the 10/22 for RFRO, same thing. Three TandemKross DoubleCross magazines, each loaded with 10 rounds each. Since they are a standard Ruger magazine (just two of them mated at the bottom) the process is to flip one over between strings 1-2 and 3-4. Replace the magazine after runs 2 and 4. They only provide the outside "shell" pieces so each one requires the internals of two standard Ruger magazines. Finding it more dependable than the Ruger 25 rounders. BC
