Yes if the bullet is magnetic it may have a steel core. It can ricochet and is also more likely to ding up the steel leaving small divots which further increase ricochet/spall.

That about covers it. Thanks all!

Thanks for clarification. As a general point, I tend to tell shooters never to stop themselves and expect a reshoot. Second question, can a specific rule be pointed to saying the target must be scored? I feel like I've seen one previously but couldn't find it last night. Also a finer point, in the case in question, competitor was shooting 40 and existing holes were 9mm. But, if the competitor was shooting 9mm and existing holes were 40 the argument is that a 9mm round could pass cleanly through 40 hole and a reshoot is required? Found that case by searching these forums.

Tried searching on this without a lot of luck. Background is target was not pasted after a previous run but calibers were different so the target was able to be scored. Rule states that "If there are extra scoring hits or questionable penalty hits thereon, and it is not obvious which hits were made by the competitor being scored, the affected competitor must be ordered to reshoot the course of fire." However if a score can be determined, is it the competitors option to take a reshoot or must the target be scored as is?

See this occasionally but regularly at local matches where people setup the corner shots a half step in from the rear fault line, except it's shooters milling around in those areas and not ROs. I tend to try to shoo them away and if they are new shooters explain why you are technically allowed to stand there, but that s#!t can also happen, and it's probably not the smartest place to be.

3lb on the dot. Rolling break, i.e. no wall. Sent from my Moto G (5) Plus using Tapatalk

I'll third or fourth the recommendations for the TTI GM kit. I have a couple 34s with these that I used to shoot in production. Been playing in single stack and limited but every time I pull one of the Glocks out I have to admit that the trigger feels real nice, even in comparison with the "tuned" xx11 triggers.

Interesting post. I have 3 9mm 1911s and use the 10 rnd ETM mags pretty much exclusively with a handful of factory mags thrown in. Some are older and some are newer but I have at least 13 of the ETM mags in rotation. Old 9mm load was a 147gr extreme loaded to 1.145". Not exceptionally long but I experienced no issues with the ETM in any gun with this load. Switched to coated bullets for new ammo but my wife is still shooting out the stash of the old plated load with these guns. Sent from my Moto G (5) Plus using Tapatalk

I just did my first experiments cutting sears on two of my guns. Used EGW kits with the standard sears and was removing material with the Harrison TR jig at the .402 quadrant. One was a kit and the other just a near sear as it already had EGW parts. Curious what portions of the jig you are using for each of EGW long nose, EE, and Harrison (is it the gunsmith sear?) ? I'll end up having to go longer eventually and wouldn't mind writing it down for future reference. I've test fired one and didn't mess with the sear spring at all and it's at 3lbs pull and clean. The other one I have down to 1.75lbs, haven't test fired it yet, but passes all safety checks. Sick of bending springs or I'd add about half of pound back in. Before this experiment, dropped a Brazos kit in yet another gun and beautiful trigger pull resulted right at 2.25 lbs crisp with a bit of a wall. No safety modifications required. Not sure what hammer they use, but harmonics are nice and it has a pretty little ring in dryfire. Pre-fit Brazos was nice as I spent about $400 on tools and parts for the experiment. Was a bit frustrated until I figured out the spring bending technique but now happy I can kind of do it myself. Was under the impression that the EGW kits are not prepped in any way, but under magnification the sear surfaces looked polished to the same degree as the Brazos.

10lb is factory I believe: https://forums.1911forum.com/showthread.php?t=209416 A lot of people prefer 9lb for minor loads: https://cdn11.bigcommerce.com/s-5t3ceeio/product_images/uploaded_images/wolff-recoil-spring-chart.jpg (from dawson precision website)

I have a Specialist Commander I've been shooting USPSA with. It makes weight with the stock magwell and no basepads, but it's a shorter gun, and drops my 135 PF load down to about 128-130 (147gr Blue w/ 3.1 N320 @ 1.10") which is getting a little close to the line for my comfort. One of the Brazos ignition kits dropped right in for a 2.25 lb crisp pull. Shoots real flat and accurate as well. The ball end mill cuts on the Specialist can make holster selection difficult. I have a Bladetech DOH for a railed commander that fits it just fine. I also have a Springfield loaded target 5" gun with trigger work that while also is nice, I suspect the chamber is out of spec or on the tighter end of things and I'm going to end up having some work done for reliability. I had to change my OAL to get one load that would run reliably for all my guns and the Springfield was the PITA. The fit and finish isn't as great, and from a satisfaction / time factor, I'd trade it in for a PM9 in a heartbeat.

I picked up a loaded in 9mm here used. It's an older model in stainless. The front slide serrations are great and I consider this a must have feature on slides now. The gun runs great, was tuned up quite a bit by the previous owner trigger wise, but the fit and finish is a bit below standards set by higher end guns, none of which bothers me much. I may start filing on the beavertail at some point and the slide to frame fit is just a little loose which is at the bottom of my care about list. You'll probably want a strip of grip tape to put on the front strap.

I have two 9mm single stacks with different ramp types and haven't experienced any feeding issues with 10 round mags and 147 rn. One of these is an older bull barreled commander Rock Island that I consider a gem considering it was inexpensive and runs really well. Almost switched .40 bullets to a round nose when the other gun was given me fits but a good local smith got it all sorted out.

It's a common problem more to do with the feeding geometry than any type of mag. Google around and you'll find better descriptions than I can muster here. I have a set of 10mm Tripp mags I use for a .40 that used to have this problem. I had a gunsmith recut the feed ramp and after a fresh spring the gun was running fine with 10 rnds and truncated nose bullets. EGW makes a raised mag catch that is another commonly suggested fix.

I was at 1.18 oal

Fwiw I just got back from chronoing 180 xtreme with the flat tip from a 5" 1911 with Titegroup. 4.2 was avg 841 fps 4.5 was avg 893 fps 4.6 was avg 923 fps which is close to 165 I'll end up settling around 4.7 most likely. My gun has a tighter chamber so I also used a slightly tighter crimp.

There's a choice between two pains in life. The pain of discipline or the pain of regret.

Clinton county farmers and sportsmen's in Wilmington also does a monthly 3 gun.

...No I didn't do it. I've been reading through load data on here, and there's some accepted loads then you get into the grey area where one guy/gal is shooting something that another guy says is unsafe. I'm OK with moving slightly and slowly outside of book max loads and looking for pressure signs, but I'm very curious as to what anecdotal or actually tested data where individuals have actually blown up guns (typical competition handguns, not magnum revolvers) from a strictly overpressure situations. Has anybody witnessed this happening or even heard about it happening unintentionally? Has anybody witnessed or heard about any controlled tests where guns were intentionally blown up?

Thanks. I'll be checking this one out.

Everything makes sense. I was mainly interested in figuring out how consistent the timers are and if there is an "industry standard" so to speak. I take away that there is a bit of an ad-hoc standard, but nothing formalized.

Is the length of the beep generally consistent for all shot timers? Do they all begin counting at the start of the beep? Does USPSA have an official list of allowed timers?

For me, the irony of this discussion is that a few years ago there was one or two Olympic shooters who were disqualified because they were using performance enhancing drugs: tranquilizers. It slowed their heartrate so they could shoot more accurately. This was probably the only time a shooter has ever been disqualified for performance enhancement, and it was for the opposite effect than what we're discussing!It's an interesting question. For the small bore events where you're trying to hold to an X ring the beta blockers or whatever they use may help. I think a modest dose of caffeine is probably not a bad choice for USPSA, but not at a dosage level that would trigger a failed test.Another interesting fact is that nicotine accelerates the rate that the body processes caffeine. I think it may even be an antidote for caffeine overdose.
