No, it isn't coincidental. It's part of how you control the timing of the gun, which is in fact part of it's basic function. Yes, the locking lugs bear a great deal of force, but another area subject to significant forces is the impact face of the frame. Shoot a hotter round, you have no choice but to wear things faster, but there is as fast as you have to, and as fast as you can. Playing the spring game can keep it down to as fast as you have to. Right on the first part, which is why you don't want to use mroe spring than you need for a round if you want maximum lifespan of the firearm. However, shoot a hotter round, and what's optimum changes. Yes, once again hotter round = more wear. I never said otherwise. However it will NOT increase recoil. A given bullet X imparts a certain amount of energy. That energy is going into the gun other than what gets turned into heat when the spring compresses, which is negligible. By and large take the same load, and stick a lighter spring under it, and people will tell you the recoil impulse is sharper. Mainly because you get more flip as the push comes suddenly when the light spring gets compressed quickly and the slide smashes into the impact face of the frame. Put a heavier spring in and the recoil impulse tends to get a bit more pushy as the impulse is spread out over the longer period to compress the spring. You tend to get the whole gun moving rather than muzzle flip, but you also risk getting muzzle dip on return to battery. Seriously? Bullet weight and velocity are interelated with pressure like Watts = Volts x Amps. I would guess JMB focused on pressure because copper discs in a test fixture were probably easier to integrate into a QA test for production that the math involved in using a ballistic pendulum to measure velocity. Today, modern timing circuits make it much simpler ot measure velocity. No, you said something between inaccurate and apocryphal, and when called on it replaced it with a more accurate statement. What you described initially would have ot be magic. What you replaced it with is closer to reality. In that I would tend to agree with you. although +P in 9 and .45 isn't that absurd, especially in a modern firearm. 9mm with it's subgun history is very capable of being run much hotter than the factory pistol loadings we have, and moder guns have the toughness to take it in stride given they are usually good to go for ammo that is as abusive as +P 9mm. .45 +P is still so low pressure that given modern metallurgy, you probably aren't pushing things too far. +P+ I feel is just stupid, If the manufacturer needs to go past +P pressures to get the projectile to perform, they need ot work on their projectile.

They are nice little guns. Trigger is so-so. for the price it isn't bad.

Really, so the slide doesn't slow any compressing the recoil spring or main spring eh? Doesn't store up any kinetic energy or anything like that? That's some slick physics magic. JMB figured out the right weight spring for 230gr ball ammo going about 830fps. Change the weight of the bullet, or the velocity of the bullet, and optimum spring weight changes. Also, just because JMB came up with an optimum wieght doesn't mean that is what shipped in any particular gun manufactured today. Also, if you are just going to feed your gun expensive +P+, might as well get a .460 rowland conversion kit and be done with it.

I Guess Aks Are So Simple A Monkey Could Use It...

Is this viral ad getting pushed again for the DVD relase or something? -
Let's put it this way. You'll shoot worse than the gun. If you put in the time to be insanely accurate, you already know who will build you a gun with guaranteed accuracy above and beyond a production pistol. Note, it won't be a run of the mill custom pistol. Unless you are prepared to drop some serious cash on a pistol, you will spend a LOT more on the ammo to practice getting good. If you are shopping in the over $4k range, the odds of you spending half on the gun and half on ammo to get decent is pretty low unless you are some kind of phenom. You can get pretty good guns under $800k that will take you pretty far.

http://roseactionsports.com/shotguns.aspx Have had them cut down and thread my shotgun. Turnaround was quick and work was well done. Cutting to lenght, new bead, and threading was $90 including return shipping. I suspect jsut threading is cheaper.

A second for the M&P. If you are looking at the glock and the XD, you should be looking at the M&P as well.

I don't put any of my opinions or affiliations on my car unless required to. You don't need to know me very well to know I'm into guns, but strangers don't need to know jack about me, and my vehicle gets a lot of face time with strangers. Like I siad, this extends well beyond guns.

Personally, for learning I like the lee reloading manual. They have a LOT of good info in the howto half, and it is cheap. You want at least two howtos, and at least two load guides, so you can compare their info. Anyplace they disagree, go online and do some research in forums and on websites to see if you can find a tie breaker or a more detailed explanation to make it make sense.

Anyone With Facts On The "indefinite Detention" Bill?
raz-0 replied to EngineerJet's topic in General Discussion
I really do have to wonder who thought it was a good idea to push things so far that the governments disapproval equals being disappeared down the hider hole for good. If speaking your mind can cause that, you might as well just shoot them if you don't like them. If it passes unamended, I wouldn't be suprized to see a bill to strike it with very little fat attached. Nothing makes for good campaign fodder like saying my opponent supports imprisoning us citizens without due process. -
Uspsa Classification... December Update
raz-0 replied to Maksim's topic in Competitive & Fun Shoot Discussion
Get used to that pain. Especially as you get to high b levels if you can't stop caring about match points at the classifier. You'll know you didn't kick butt, sandbag a little to try and not screw your average, and get whacked wit the high 50s/low 60s and need 6 decent performances to erase it. A gives you a lot more freedom if you just feel like getting stage points for the match. You should have no problem getting a if you don't slack off. Master will take a lot of free time and some regular live fire practice I suspect. -
Uspsa Classification... December Update
raz-0 replied to Maksim's topic in Competitive & Fun Shoot Discussion
That's what I said when I got my c card. I actually practiced and junk. Got my b card like 5 months later. The a card took 6 more years. Like I said the b card isn't that hard. Shooting solid b level at matches is much harder, because you need b level movement, and the classifies are pretty much stand and shoots. If you want the card, a timer, some dry fire practice, and Steve Anderson's refinement and repetition will make a huge difference. He breaks down all the classifier skills into easy to practice chunks. If you want to shoot high b level at a match, it'll take more, but it should improve your shooting foundation. -
Just in case you didn't know - stock up on light bulbs!

Btw, the lightbulb thing was just defunded. The reality is as we headed into the 60w "ban" even LEDs wouldn't be ready to meet the efficiency goals. -
Uspsa Classification... December Update

Getting out of c and into b isn't as hard as it seems. B is a huge PITA. You can screw up pretty bad and it still counts so you do a LOT of dragging your average back down. You're aiming for 75 to get out, and everything down to 55 counts. -
Polygonal rifling aside, you don't use lead in a DE because the lead will fould the gas port. It's a gas operated pistol.

1lb=7000 grains. It's simple math.

That doesn't assure you that the case hasn't been weakened, just that it hasn't lost any mass. I'm not saying that steel media would cause thinning ina case wall, but it might peent he neck over a bit and increase the likelihood that the normal reloading process can damage it.

How Many Rounds Do You Shoot Per Month?
raz-0 replied to this_is_nascar's topic in Firearm Hobby / Sport Discussion
Peak was about 750 a month centerfire. average for a long time was 475. Now, it's probably less than 300. It's time, not money. -

I got my l-10 average up to 77.something, which is the highest I've been. Gotta decide if I want to shoot production again or stick with l-10. -
The first time he tries to clear it, it looks like a failure to eject or a double feed. Later in the video it looks like there are several instances of operator error, probably from stress and assuming everything going on is related to the initial failure. It looks like he is trying to clear a jam when the bcg is locked back. It looks like gravity is the only thing making the charging handle go forward. As for failure, I'm guessing bum mag or bum ejector for number one possibility. Number two possibility is him being a victim of logistics. They have had issues with ammo stored in direct sunlight too long getting too hot and having the powder get wonky and increased pressure from the rounds. One of the main issues stemming from that have been primers backing out or getting blown out of the brass. It's possible he cleared it like a double feed, but the foreign objects gumming things up were spent primers. Which might explain the locked back bcg at the end might have locked it back so he could try getting them out of his trigger group. Only way to really know is to ask the guy in the video.

Obrpc Uspsa December Classifier
raz-0 replied to hd2000fxdl's topic in Competitive & Fun Shoot Discussion
This isn't IDPA, it's USPSA. You can reload whenever you want to as long as you reload when required to during a classifier. Virginia count means that there are a specified number of shots and hits. Lets say a course is 6 targets, 2 hits each, 12 shots. You shoot 13. one penalty. You shoot 14... 2 penalties. If you go score, and for your 14 shots, there are 13 hits.. 3 penalties. Only 12 hits for your 14 shots, 2 penalties. extra shot is -10, extra hit is -10. If you aren't a USPSA member, the classifier match isn't for you as space is limited, and the scores couldn't eb filed for you anyway. -
Obrpc Uspsa December Classifier
raz-0 replied to hd2000fxdl's topic in Competitive & Fun Shoot Discussion
classifiers are all sorts of lengths. 6, 12, 18, and 24 are very common round counts for VC classifiers. Given what classifiers will fit indoors, 100 rounds should be more than enough, even if you need a reshoot. Technically, I believe they could fit 3 18s and a 24, but probably won't. -
Uhh.. to buy online it has to go to an FFL. If it doesn't, it is ALREADY an illegal sale that is banned. How will re-banning something already banned help? How will banning something that has nothing to do with the other thing help?

That's going to cost you more than $750k.
