Butane Lighter!  BUTANE LIGHTER!   Against all that's holy to the Bullseye shooters, e-gads man, where's your carbide lantern?    ;)




I tried the carbide route for my silhouette gun, what a mess.  Then I tried the butane lighters.  They were okay.  But I settle on plain old candles.  I'm not doing this outdoors at the range so the candle route works for me. 


btb, don't know what size it is but the peep sight on the Ruger PC-9 is just perfect for me.

OK, bit the bullet and got one of the flip up fiber optic sights from Striplin Custom... works well, bright even in umbrella shaded shooting box... now I just have to get used to using a front sight and looking through an AR rear sight...  8)

Les, one of these:  https://striplincustom.com/product/fiber-optic-flip-up-sights/  ?

And by the way, I'm just a little jealous of you guys's (that's right guys's ) shooting so much.  You need some home projects like I have to stop all of that fun.  No one as old as ya'll are supposed to be having fun!

Oh, and also by the way, That Striplin Custom website has some interesting kit to consider.

Rastus... yes, they are a little pricey, but well built...I originally had an AR front sight tower, but could not track the sight quick enough for Steel Challenge...I changed to a 1913 rail fore end, and use the Striplin flip up fiber optic sight...I tried a couple of standard flip up painted sights, but went with the Striplin as I was familiar with his work... I have his thumb rest and extended safety on my Ruger MKIV... I like the standard AR rear carry handle sight, but still playing with the correct diameter of the aperture sight.. I'm getting close

I got my A card in optics, and want to play with the fixed sighted upper for a month or two and see what kind of classification I can get with it...I'm having firing pin spring breakage problems currently... regards... Les

well the 3/32 didn't work for me... too much metal around the fiber optic dot to acquire targets quickly... very accurate, but just slow... opened it up to the original 5/32 trial aperture as the best compromise... Les

So what's up with the firing pin?  How much life are you getting out of it?

Rastus... I really like the Bore Buddy firing pin due to the way the nose impacts the cartridge rim just below the rim edge...  I also use one of their wire EDM extractors ..my original (early) CMMG pins did not have a radius where the diameter of the pin reduced to go through the bolt face, a problem the newer CMMG pins have fixed...I broke a couple of OEM pin at about 2500 rounds... I'm shooting about twice as much now (1200 rounds a month) and broke the first Bore Buddy pin at 8000 to 10000 rounds ( I don't really keep track of things I should).. I've recently broken two of the Bore Buddy firing pin return springs but it did not effect the function... I switched lubricants and am now back to my old standard of Mercury Outboard Quicksilver 2 cycle racing oil...additionally I broke a RRA NM hammer in the .22...I have two CMMG uppers and a back up bolt group also with a Bore Buddy pin and extractor, but hold it in reserve... the CMMG units run well on CCI SV but the Ruger MKIV is not 100%, so I was getting SV and Blazer/Mini Mag... I've now standardized on the CCI AR Tactical in the 300 pack... Glen's Army Navy Outdoor usually has a good price, (you have to scroll down the page) and free shipping on $50 or more... I broke the feed ramp on one collar when I unknowingly used an old short collar on a newer barrel stub that shouldered on the feed ramp and not the nose of the collar.. so I plan on shooting the fixed sight upper to improve the poor stage I shot that day, and is figured in my classification..the upper with the Holosun 510c is a blast to shoot, now that I've gotten experience with the green reticle....regards Les

The good thing is you are getting to shoot a lot!!  I bet I haven't put more than 300-400 rounds through my oldest CMMG and maybe 50 through the new one (sale, could not refuse). 

Quicksilver, what's the focus on that for oil?  Handles dirt from the 22 rounds without gumming up? 

And thanks for the Glen's Army Navy heads up.  They have really good prices on that CCI Tactical ammo.

Rastus... the Quicksilver 2 stroke oil idea came from a friend (30+ years ago) that at the time had a go-fast boat that was running a Mercury 3L outboard... he had problems with spark plugs fouling ... the Quicksilver oil dissipated carbon for him, and at the time worked well for me shooting a 1911 (back when MB was shooting in the Tampa Bay area)... have used it since, but got away for a time using Hornady One Shot... the One Shot dry lube did not accumulate fouling, but didn't seem to lubricate the firing pins as well as the liquid oil... 

as for the number of shots.... Steel Challenge consist of 8 specific target arrays, and there is very active Steel Challenge shooting community here in the Tampa Bay area, offering lots of opportunity to shoot... and with the price of small pistol primers, I can shoot one .22lr cheaper than a primer alone ...one local range has a Friday and Saturday 5 stage match each month, and a practice match (3 target arrays we shoot twice) each non match Friday... the Wyoming Antelope Club in Pinellas Park has a 6 stage match monthly, and Gun Craft range in Ruskin has a complete 8 stage match monthly...5 shots (minimum) per stage, 5 runs is 25 rounds per stage x 5 or 8 stages is 125-200 minimum a match...so I'm averaging over 1200/month... the .22lr is much harder on equipment than any of the other shooting sports I've be in... regards Les

Now I know about the Quicksilver.  I will pick up a can or two if I can keep it in mind.

I know you dodged the hurricane but how about the birthday?   ;D
