I find that some people, for completely mysterious reasons, have an aversion to email. This behavior typically falls into several categories: 1. As you mention, not using it even if it is readily available. 2. Having a published email address, but checking it very infrequently. 3. Reading incoming email, but not responding, even when asked a direct question with a question mark. I know several like this. And these people are otherwise fine folks. I guess that they regard it as something foreign and synthetic, and not genuine personal communication. Or, perhaps deluged with unwanted but well meaning attachment email from friends, combined with spam, they regard email as an annoyance. Beats me.

Agreed. I think most people are most interested in paying for a class at the beginning of the "season". Early April sounds nice ...

40 caliber primer comparison 9/10/09 Bullet: Precision 185 gr RN (186+ grains by actual weight) with 4.61 gr VihtaVuori N320 powder. Cases: Various, loaded to 1.179” OAL + - .001 Observed differences between 3 primer brands. As shot from STI Edge, 84 deg F. Measured with Pact Mark IV Chronograph with 48” spaced skyscreens (increased distance to minimize skyscreen transducer error contribution) 8 samples were fired for each primer type. Gun allowed to cool to ambient between each sample group. No malfunctions. Vel mean rounded to nearest integer. Winchester SP Vmean 919 fps PF 170.9 SD 14.4 ES 40.8 Federal SP Vmean 924 fps PF 171.9 SD 16.1 ES 48.9 Magtech 1-1/2 (SP) Vmean 935 fps PF 173.9 SD 10.2 ES 29.8 Related to this, using this powder with this bullet, Win primers, 1.179” OAL, shooting from an STI Edge, I’ve collected the following averaged trend data over the last 2 years. The image is from a spreadsheet that an unknown author (on this forum) sent me. The user inputs load data and velocity results, and a linear trend line is interpolated. It has different pages for different user-supplied loads. YMMV Chris

You will make mistakes. Admit them, learn from them, and be fair. Many scorekeepers get only on-the-job training, with little preparation. For this reason I put together a web page tutorial on how to do it - with an example of a properly completed scoresheet. This way many of our new folks have a bit of a heads-up before they get "volunteered" to do it - and it does appear to have helped.

I have not used Gimp, and must say that for the cost sensitive, it looks interesting. But I don't think anyone who works in the graphic arts industry will deny that the Adobe suite of software is the standard by which others are measured. There are other products that beat the collection in some sectors, (for instance Premiere is not even close in professional popularity to Avid or Final cut) ( Illustrator also has some equals) but Photoshop has been the flagship product for a long time and remains King. For pro use, the cost is pretty small. Price IS the issue for hobby users. I am always very hesitant about investing significant time (and all pro products take time to learn) in software that is not a contender for best of breed for my purpose when I need to use it professionally.

Aside from the obvious collection of versatile tools Photoshop has, one of it's amazing features really shines if you do anything for web pages. An often newbie-neglected web photo issue is file size and load time. The companion 'ware Imageready is supplied with my version of Photoshop - this lets you do an amazingly effective job of minimizing file size while maximizing resolution, color depth and detail. I understand with the latest CS Photoshop series, these functions have been integrated into PS itself ("Save for web"). I've not used Fireworks, but that product has related features. I have an older version of PSP, but find it pretty limiting. More recent versions may be better. I hate Adobe's overpricing, registration requirements, and marketing, but like it or not, it is pretty much the industry standard. Chris

Your next "must have" will be an electronic darkroom called Adobe Photoshop.

Count me in!

Well, alright - Lewisport ( Very close to Owensboro - ORPCI.org ) is my home club. I'm interested. Uh ... when ? Chris

For a given velocity, with slow and fast powders, the MEAN pressure will be the same, but faster powders will have higher (sometimes much higher) PEAK pressure. The most experienced shooters all seem to agree that for non-comped guns, fast powder and heavy projectiles are most competitive in our game. This may be a purely empirical and subjective "feel" factor. The limit is safety - (Clays with heavy projectiles can Kaboom) You may notice heavy or "magnum" pistol loads will usually be prescribed with slow powders to minimize peak pressure.

Conventional wisdom with non-comp guns is to propel the projectile at design speed, but burn all the powder by the time it leaves the barrel to avoid further unnecessary "jetting" of gas which adds to felt recoil. This promotes faster sight return. Carry the idea too far with really fast powder and heavy bullets, and the peak pressures can get out of hand.

The quick method I use which coats the outside without getting inside the case: Spray the lube into a gallon size ziplock bag. Drop in two large handfuls of brass. Seal, rotate, agitate for 10 seconds. Unseal, pour lubed brass into machine. Chris

I've been using Firefox for years. Our entire organization of 2K employees has switched to it. Also check out adblock and no script add ons. Chris

Imagine bullets launched at 6 feet (eye level for a tall guy) pulled high, impacting the 6 foot level of a 7 foot berm that might only be 12-14 inches thick at that height ...

Pasters look better and obscure less perf per paste, if only they would adhere better - in hot or damp weather the things fall off making scoring difficult. Another local match uses masking tape - looks like hell but seems to stay put.

Range design safety seems to be a grey area depending upon who one talks to. I've been to quite a few practical ranges, and the side berm heights vary considerably from "darn safe" to somewhat worrisome. Few practical ranges I've seen have berm heights in compliance with the NRA range handbook guidelines. So, assuming a standard triangular piled earth type berm, with another squad shooting next to you, with you downrange pasting targets, what is the minimum height you would feel safe with? Obviously, cost is a concern, otherwise they would be 15 feet. I ask you to respond to the poll only if you have been to at least, let's say 7-10 different practical ranges, and have noticed side berm heights, or have seen incidents relating to side berm heights. Too bad there isn't more practical guidance on this subject. Thanks for your opinion.

Just about the time I decided to try the Chip McCormack AR trigger, nobody, including CM has any stock, and isn't expecting any for at least two-and-a-half months - due to parts problems ... Anybody who has stock on this - please pm me.

I used a manual mill for maybe 10 years or so, and am in the finishing stages of building a 3-axis CNC mill with Mach3 software - of similar size to your bridgeport. It's hard to tell in the photos, but if you don't already have DROs (digital readouts with no backlash) that should be high on your priority list of accessories.

According to one very well known top shooter; Use the lightest value recoil spring you can and still get 100% feeding reliability. This is optimum for best control when shooting fast. There are two downsides to running a light spring - at some point, it won't have enough energy to reliably shear rounds from the mag and chamber them. The other is increased shock to the frame which may eventually lead to cracking (this can be helped with shok-bufs). He also said to use the lightest slide you can (minimize reciprocating weight). This guidance is from the standpoint of competitive advantage, not reliability.

Unlike DC speed controls or "lamp dimmer" speed controls, AC motor drives do not reduce the electrical energy at lower speeds - instead they "remanufacture" the AC waveform entirely - and instead of it changing polarity 60 times per second as in normal 60Hz power, they vary the frequency of the remanufactured waveform. And the AC motor stays synchronized to the incoming frequency. That is not to say they have infinite range, but they're a lot better than other methods.

Now that inexpensive AC motor drives (solid state speed controls) can accept 240 single phase and output 3 phase, all of the other phase converters are largely obsolete - it really is the way to go - and gives the great benefit of fine rpm control too.

Today we "broke ground" on our new bermed 5 bay practical range. Several years in the making, we finally got some money allocated, and began construction today. It's in a very low area, but not so low that flooding will occur. I've put up a web page with pictures that I'll update during the construction - expected to last another week. Now that we won't have to set up on the rifle range anymore, we can do some more elaborate stages. We expect USPSA sanctioning of our pistol matches in a few months. http://orpci.org/content/bg/bgrange.htm

No rebuttal, several thoughtful points have been made. It has crossed my mind - WHAT IF. What if we took in a new, semi-rambo shooter for a match, who turned out to be a total psycho and tried to commit major violence to a squad during a match? A few would probably suffer gsw, but I think he would be stopped in about two seconds, even with everybody unloaded and holstered.

I'm definitely going. Check will be in the mail Monday.
