That is an innovative approach to the modification.

Removing a little material from the bottom will save you a lot of bolt grinding.

That is what I was going to do, after I cut the
Pin to lenght. Then fit the pin to the bolt.

i am not the best at silver soldering ,but it is a firing pin now.
now all i have to do trim to size, then finish the bolt then test.

Somebody tell me why simply shooting the rifle upside down through a chronograph wouldn't answer the question without fabricating anything? Maybe shoot straight down from an elevated platform and then shoot it straight up! That would put the six o'clock speculation to rest in a hurry. You guys are trying to pick a spec of fly crap out of a pound of pepper.

Ain't heard me that one before. 👍

On topic. Tinkerers going to tinker. For BR autos it might amount to something. For the HP ammo I shoot at varmints and game.... Although better is superior and all that....

Most of the things you read on forums are anecdotal. Few people actually get out there and do work, record results and present the results for review. I linked to what I thought was an outstanding experiment and not a whisper. I saw a couple of things that jumped out at me.

I was hoping to shoot through a chronograph next week, I'll see how I feel. I am convinced I am the only person that owns a chronograph on this forum so that may explain why it hasn't been done yet. For all the interest and discussion on the 10/22 forums, I find them to be the least curious about hard data. This forum thrives on anecdote. That's fine, it's fun, but...

Having said that, some people just like to tinker. You?

You're going to scallop the face into a 12 o'clocl/6 o'clock strike leaving the center unsupported, right?

If so, check the rear of the cases for pressure signs. I doubt there will be any.

Well, the pay's nothing to write home about but it's honest work Bigbore

I love a good gedanken experiment and this thread is certainly thought provoking.

I suspect that a simple consumer chronograph will not have the precision necessary to differentiate the slight ignition timing differences between firing pin locations but am certainly willing to wait and let your data tell the story.

Got me thinking about a full rim firing pin like a bushing. Take a heckuva spring to crush the full circumference but it'd cut down on FTFs.

Good fun, thanks for the brain food, looking forward to nit picking your results

Happy Thanksgiving Everyone! With the 12 and 6 o;clock positions, the only way your going to have consistant;even ignition is to hold the rifle perpendicular to the ground so that all the powder in the case is back against the primer. Centerfire, lead bullet shooters have been doing this for years to get the reduced powder charge resting against the primer, then slowly lowering the rifle into a parallel position to fire at the target.

With 3 and 9 o;clock position this would not be needed because the powder would be ignited from both sides of the case where the primer impact is directly behind a powder charge.................

You would probably get more co-operation from somebody in New Zealand or Australia. I think they are still allowed to own .22lr rifles.

You are kidding I hope. Maybe you can document how long in milliseconds it takes for the priming compound to burn from the top of the case to the bottom. This whole conversation is a joke. To bad not many of you recognize it as a joke.It's pretty tough to reinvent a wheel.
