  1. If the edge of the extractor cut (leading into the chamber) is sharp you should ever so slightly polish off the sharp edge. Do not remove a lot metal and expose too much of the shell rim – just round off the sharp edge
  2. In extreme cases you may have to cut it with an abrasive cut off wheel. Place a thin shim between the crush washer and barrel shoulder to avoid contact the wrong part with the cut off wheel.
  3. I see a trend here. Stick with 1200 fps or faster with 1 1/8 oz. of shot for the best results. Winchester AA Heavy Target (1200 fps 1 1/8 oz. of shot) is my go to in the M2 and 1301. The 1145 fps load runs most of the time, but with the 1200 fps load ammo related issues are nonexistent.
  4. Interesting....Does the machined out area leave 2 post to set the Dot on to, and have a radius on the front of the cut?
  5. The Marlin mount is a fraction lower than the Sumtoy.
  6. Yes I do. Take a look at using the Marlin rifle base in this link. We have installed that mount system on several hunting guns. Burris red dot on a shotgun using a Marlin rifle base
  7. We have drilled / tapped quite a few guns including M2s for Weaver, Picatinny and custom type optic bases. The rear section of the M2 receiver is thick enough to securely hold most optic mounts. Sumtoy (and maybe others) make custom bases that set a Fastrife and similar dots lower on the receiver that rail mounting
  8. Are you continuing to press the bolt release while you insert a shell into the magazine tube? If so you are also pressing the shell latch against the shell that is being inserted causing it to hang as you noted. There is no need to have to "uncock" the gun before loading. Cycle the bolt to cock the hammer, engage the safety, load the magazine tube. Now press the shell release button (rectangular tab near the rear/center of the loading port which will eject a round from the magazine tube onto the lifter. You can cycle the bolt to put that round into the chamber when you are ready.
  9. https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=2ahUKEwjNmsrI7aLoAhVvUN8KHc_YBtcQFjABegQIAhAB&url=http%3A%2F%2Fns.hodgdon.com%2FPDF%2FMEC_BUSHING_CHART.pdf&usg=AOvVaw2N734AOC7yzsY7X1Brqbtb Link opens the MEC bushing chart as a PDF file
  10. How much of the vent rib do you see in your sight picture? If you see any of the rib (between the front sight back to the rib's “ramp” a couple of inches in front of the receiver) the slug POI is probably going to be high at 50 yards....gotta say though that 3' high at 100 is quite extreme. ABarrow's question about a barrel clamp comes into play too, pressure from some clamps can put upward pressure on the barrel causing the POI to rise
  11. I checked Amazon and Brownells...no luck. Same with BassPro... You probably need to check with the guy that invented them. Last I heard he was somewhere North of EDEN...Wyoming
  12. Does a shell exit the mag tube and remaining laying on the lifter when the bolt locks open? Does this happen when firing the gun - or only when you hand cycle the shells out of the mag tube? When you manually activate the cartridge drop lever (sliver tab) will shells exit the magtube - or will the shell move side to side and sometimes fail to get past the shell latch?
  13. Has the loading port been opened significantly? Has the shell latch been "tuned" in some way?
  14. The bolt release/cartridge catch part is a different part # on the 1301 TACTICAL vs the 1301 COMP. That A400 / 1301 Tactical part may not work in the longer COMP receiver.
