Daystate mag question

[5thumbs]

Very interesting post. Thanks to all for this information. Yesterday I opened up my 6 magazines (5 for Red Wolf) and used a Dremel Tool to grind down the tip of what is described as the "hook". Put back together and groups tightened up. Granted, the RW shoots great on my patio @ 20 yards but the "one hole" groups are smaller (maybe better said as there are less of the larger one whole groups). I may grind them down a bit more to see if there is further improvement.

The new magazines are self-indexing. No indexing pin necessary.

Yes, but if you want to use the old style too, you need it. My point, there seems to be no need to replace the index pin with a new style. There is more than enough clearance in the bottom of my new mag to avoid the pin contacting the magazine. That's what I meant by there appearing to be a change made. There has been discussion about the pin slamming into the bottom of the new mag and breaking it. The recess in my new magazine appears to provide sufficient clearance for the pin when it pops up, more clearance than in the bottom of the single shot tray.

As far as I know, AOA has been removing the index pins for people choosing to use the new magazines.

Rich didn't mention it when I ordered my mags, but he said yesterday that I needed one, and I just received it. But I believe Daystate has made the recess in the bottom of the mag deeper, mine measures .115", which is deeper than the SST recess, and the clearance appears sufficient. I'm going to make further inquiry.

I recently received a .177 Pulsar HP. It came with new mags (I did not make any specific request, thinking that I would modifiy the mags if old style were received). There IS a pin in the hole where the indexing mechanism sits. The space in the mag overlying that location is quite deep and could not be contacted by any pin that wasn't at least 1/4 inch long. Surely seems to be confusion over exact procedures being followed.

I got a big accuracy improvement from a small modification to my old magazines. Shooting a Regal XL .22, the magazine groups were were previously 2" at 30y. Horrible! In between then and now I resealed the pellet probe, transfer port and valve body. I modified all my magazines by scraping/leveling inside where a metal brace is molded into the plastic to hold the escape lever. I believe the edges were scraping swarf off an occasional pellet. I observed those fragments under a microscope at dissassembly. I smoothed (round knife edge), cleaned and reassembled.

Although I haven't tested beyond 100 pellets the magazine shoots 'almost' as accurate as the SST. In the test groups the SST won 2 of 3, close enough that I can call them equivalent in accuracy.

But - I don't have long term data to indicate whether the smoothed edges or the clean magazines were the factor.
