2 Questions

Post by frank » Sun Jan 04, 2009 11:20 am

#1 I've had some issues(again) with Fed bulk packs. On advice, I stoned (just a bit) the side taper of the firing pin on my MKIII 512. Didn't make any diff as far as I can tell. CCI blazers work fine. Q- Would a harder hit make any diff in weak loads? I've got a particularly bad batch- I had one yesterday that I swear I could see to the target. Needless to say, it did not cycle the bolt.

#2 As a senior, I have sight issues. Anyone tried making a pair of shooting glasses with short(sight) focus on the right and long focus on the left?

Typically the priming compound is the weak spot in rimfire cartridges. How deep or pronounced the firing pin case hit is doesn't usually matter in poorly primed cartridge cases - as you have seen by your own experimentation. This is one reason why rimfire match ammo is so much more expensive, as it has more consistent, priming methods to detonate the cartridges more uniformly. Bulk ammo is not made that way tolerance wise and therefore typically has some ignition issues.

This would be something you should discuss with your optician. He could make a specially constructed pair of glasses of this specification. I could see binocular (depth) issues with a set of frames constructed this way but since they are just for shooting could be swapped for any regular vision issues like scoring targets. Another way is to get a set of shooting frames, like Knobloch's, that have diopters extended out from the shooter's eye. This style frame can be used in concert with regular glasses and have the proper diopter lens for close shooting on the frame. You can swing the special lens away from view when performing any task that requires normal vision.

Your experience with fed bulk is typical. I get 1-2% failure rate, even after multiple strikes. Just the way it is. Look at it as a training aid to see if you are anticipating recoil 8)

As for eyesight, I guy in my club found a little plastic film that fits to regular glasses to sort of turn them into bifocals. He puts one on his shooting eye when he shoots iron sights and says it works great for him, cost about $2. Your mileage may vary.

Good suggestion, I hadn't thought of that option. Here's a similar product. http://www.stickonbifocals.com/

Here's what I've done. I've taken 2 pair of reading glasses--one 1.00 and another 1.50 and married the 1.5 right eye lens with the 1.0 left lens.

I planned to use them in our indoor league tonight, but couldn't make it.

I'll have to wait till next week.

I look forward to hearing how that works out for you. You may be on to something for those with optically challenged eyes - like myself.
