Yes when I still shot limited I switched to a 6" for much that reason. It helped a little. Glasses would help more (or a switch to a dot division like I did.)

I think C-More uses the same LED in all of the dot modules, the aperture size is what changes.

This.... Some dot modules just seem to kill batteries quicker than others. I've hit this a couple of times ove the years and swapping the module seemed to solve the issue.

I was sceptical at first as well.
But I got the footprint for my gunsmith to do the mounting directly from the product manager at SigElecroOptics here in Wilsonville. He said this was the engineering recommendation.
He was saying that the mounting area is designed to take it, and that especially the front of the housing was not meant to take the impact, and
it seams to transfer directly to the glass above and cause more issues when fit tightly...
I cracked a lens on a romeo3max of mine due to this on my open gun... Since I have gone to a mount that doesn't fit as tight to the front of the scope body(and has snug locator pins) I have had no further issues.

I think those were either cpi base pads or maybe something sold by Wayne bergquist when he ran glade gun works? Best bet would be to look in the archive issues of front sight around the time you got into uspsa (early 90s?) and look at vendor ads.

Are you looking for some sort of adapter that lets you use a different footprint dot on a slide that's been cut to allow a direct mount of the viper? If so then what you ordered isn't intended for that. What you ordered is the adapter plate for a pistol with a multi optics cut to specifically mount a viper.

It is the AWT "Tomahawk" short action , which is based on the Remington 700 footprint, with a .440 diameter bolt face. We are waiting on my stock to arrive.
So I'm a little curious I guess, in a short action bolt gun why go with the necked down grendel instead of a 6 creed or a dasher or a 243 for more velocity?
I can see the 6 grendel or ARC in a small framed gas gun for sure. (I've tried to talk myself into building a bolt gun in 6 grendel or something like it and was curious about your thinking.)

Advanced Weapons Technology is building me a 6 ARC bolt gun. I am really looking forward to receiving it.
Which action are you going with?
-
And I'll 3rd that... Awwww.

Hope that doesn't cause consolidation of product lines... I've loaded Ramshot Silhouette for my major pistol loads for a long time. I'd hate to lose access to that (or accurate 2520 for that matter as it's my go to powder for my 6.5 grendel.)

I like Federal as that's what my gun is set up for. Winchester is also good. Between the 2 or those I can get all the brass I want.

well, thats what engineering is all about
years ago i wrote a suite of programs for invoicing, stock management, accounting etc.
it all fitted on a 1.2 MB floppy disk. a 120MB hard disk would store data for 3 or 4 years of work for a middle size company, with space to spare.
now i have a virtual machine with an empty Windoze 7 running on it. i just had to resize the virtual disk as at 40GB was already full...
I mean in this case you could shorten the thing and extend the battery life... But at this point I suspect they are content to sell them as is to the people who still want them and not incur the additional tooling and engineering costs.

pot's leg breaking must be quite unusual, never seen it happening. one of my colleague shooter had the pot knob breaking, thats the only cmore pot i have seen failing so far. i am in several clubs and i have a reputation for fixing electronic stuff so i usually know about broken things.
really not much going in inside a slideride...
Kinda a shame with all that board space they don't add an led driver (to give pwm) and ATtiny microprocessor or something to control it. But I guess simplicity and low parts count has it merits in durability.

You are correct about the overall process. I just wanted to improve the chance of passing using the first 3 rounds so not to stress out about it.
Makes perfect sense.

Per 37, one additional round is used. Could improve your chances or make things worse. It's a gamble.
This is why I calculated the Z parameter using only 3 rounds. I didn't want to worry about what happens next.
That's not the way I read that.. They take 8... Pull 1 to weigh. Then they shoot 3. Then if you don't make it they shoot another and take the 3 highest... If that doesn't make it they do it again and recompute. If that doesn't make it you have a choice on the 7th.. You can have them pull the bullet and weigh it... Or shoot it. The result is your attempt to make pf is actually based on the average of the highest 3 velocities out of 6 or 7 rounds depending on what you elect to do with the last round. Look at the part at the end where it talks about this will continue...

I've had that problem with them before. My fix was polishing the firing pin a bit to get it slicker(and lose a few thou off the diameter.)

Basically I agree. I generally shoot two separate magazine loads of 20 rounds each. (With lower count mags I shoot 20 test rounds by whatever means necessary). Out of this I would expect to see each test to have a SD of 5 and absolutely under 10. I also expect the individual tests to agree within 2 PF's and usually +/- 1 PF.
The Z test above is interesting but not necessary. Keep in mind that statistically in a normal distribution of numbers +/-1 SD represents 68% of the population of the sample and +/-2 SD represents 92% of the population. While I'm not claiming we are dealing with a normal distribution, we have little chance of dealing with anything else mathematically.
So if a get 167 Avg of 20 rounds with a 7 SD my actual sample predicts 68% of my rounds will fall between 160 and 174 68% of the time. That does not give me a strong chance of passing chrono when they shoot 3 rounds. No way I spend a bunch of money and time betting on success here.
So how about a 172 avg with a 7 SD. that looks a lot better but still leaves a nervous feeling when only looking at 3 rounds. Im not a lucky person.
I just finished approving my load for an Area match. I got two 20 round samples to agree perfectly at 173PF. One was 5 SD the other 6. So using the 6 I easily show 68% of my rounds are between 167 and 179 and 92% are between 161 and 185. I think I can live with that because the chance that chrono pulls two of 3 rounds below 165 is terribly small.
Frankly I would add that I have another criteria. I don't want any round of the 20 round test to fall below 165. So actually no matter what the math says I don't want any failures in my test. I have never failed chrono and I am not going to take a chance. Im still nervous though.
But what if they take the highest 3 velocities of 7 rounds (per item 37 and 38 of appendix C2) to do the calculation?
-
Why did you want to ream it? If you want more clearance why not just chuck the firing pin in your drill and wet some fine grit sand paper with a little oil and polish it down a little.

I'd buy an electronic copy.

Waiting anxiously on mine. I've used their over the ear muffs for ever. Be nice to have some decent in ear.

Body armor is all too common these days, so if you're going to the trouble of building/buying an AR, do with a rifle cartridge. This is my EDC backpack gun. LANTAC LA-SF15, 7.5" 300BLK with their BMD.
Trace if you don't mind me asking, what load do you use?

Right. I'm thinking I can afford to lose capacity. Currently I'm running 11 grains 3n38, mostly because I got a good deal on 4 pounds, and was planning on shooting 9 major. Making pf with the rather large case is pretty easy. So I'm thinking I've got plenty of room to try heavier bullets and popples. I'm THINKING I'll probably just go with 124's and popples.
The two matches I shot it at, I advised the ro's to double up on ear protection. The guy I talked to said he didn't feel like he needed both plugs and muffs. That's in a completely outdoor match though. If there's even like a roof overhang though, golly gee is she loud. Can't speak on actually being NOT directly behind it.
I'll give n110 a try, I think I have a pound of it

So I gotta ask why the popples? Is it not flat enough at the new PF? Mine with 124s and 180 pf (and something like 16.5 or 17 gr of N110) was essentially perfectly flat to the point of the dot actually dipping slightly (but more just vibrating a little)
-
I suspect with a bullet that long and a case neck that short you'll lose some case capacity...
I used to use n110 and 124gr bullets in mine back in the day at 180 or so powerfactor..
With the pf for major now at 165 I suspect either h110 n110 or even something like shooters world heavy pistol would do what you want with more or less smoke.
I suppose if you poppel it you can lose some pf and keep your charge weight up somewhat... Mine was bad with just a comp the concussion was so bad the ROs would argue over who had to run me. With poppels it would be much worse.

I shot it as a provisional division when they first offered it. For me (normally an open shooter) I was looking for production with a dot
I was using an m&p core with a first gen deltapoint. I liked the whole idea of production with dot.
I don't love the changes to turn it into open lite and so went back to shooting open when those changes were allowed. I understand the reasoning for the changes (and don't fully disagree with it and the way it has driven development in that space.)
From the perspective of growing the division and brining in folks who were looking for a place to shoot a gun with a dot (and making a place for normal guns with dots on them) , overall I think it's good... If for no other reason than when a shooter shows up at the match with a normalish gun with a dot on it I don't have to have to break the news to them that they are competing against full house race guns.
I picked up a bull shadow recently from a friend that's been milled for CZC optics plates and will probably stick a dot on it and dabble some more in it later this year. To see what I think about it now. This gun wasn't (I don't believe) avaliable when CO started nor would it have been legal (too heavy)
For reference I am a middle of the road open M and former (and occasionally still) Uspsa match director.

Yep I'd shoot it till I hear back from them... I have an open gun with a hybrid barrel that has a slot cut all the way down that part of the slide for the barrel rib. The crack starts at one hole and stops at another... Unless other cracks form (particularly headed back toward the lugs). It wouldn't worry me that much.

To get that you'd have to have a long dust cover gun shorten the slide and then fit a comp. You'd probably need a new barrel unless it was a bushing barrel and you threaded it for a cone style comp. Not sure of the attraction (other than a shorter gun with long dust cover monolith look?)
