Noticed that Sellier & Bellot FMJ 2903 is listed in my table as having a G1 BC of 0.255, while the manufacturer webpage states 0.300. They are also apparently a little unsure as to whether the bullet is 55 grain or 3.60 gram. https://www.sellier-bellot.cz/en/products/rifle-ammunition/rifle-ammunition-fmj/detail/180/

Found a large test done by Lucky Gunner Labs in 2013: https://www.luckygunner.com/labs/brass-vs-steel-cased-ammo/ 10,000 rounds were fired through each of four Bushmaster AR-15's with 41 cm (16 in) barrels. Muzzle velocities and accuracy was presented for these cartridges: Federal 55gr – Brass-Cased – Copper Jacket Wolf 55gr FMJ – Steel-Cased with Polymer Coating – Bi-Metal Jacket (steel and copper) Brown Bear 55gr FMJ – Steel-Cased with Lacquer Coating – Bi-Metal Jacket (steel and copper) I asked the author, but the raw data was not available anymore. Anyway, the following tables are based on reading the graphs: Muzzle Velocity (3.56 g, 41 cm brl) Muzzle Velocity (55 gr, 16 in brl) Rounds Meters per Second Rounds Feet per Second Federal Wolf Brown Bear Federal Wolf Brown Bear 0 913 911 919 0 2995 2990 3015 2000 908 908 911 2000 2980 2980 2990 4000 899 910 908 4000 2950 2985 2980 6000 892 899 887 6000 2925 2950 2910 8000 896 872 872 8000 2940 2860 2860 10000 881 881 860 10000 2890 2890 2820 Barrel Accuracy Barrel Accuracy Rounds Milliradians Rounds Minutes of Arc Federal Wolf Brown Bear Federal Wolf Brown Bear 0 1.2 1.2 1.2 0 4 4 4 2000 1.0 1.2 1.3 2000 3.5 4 4.5 4000 0.9 1.3 1.2 4000 3 4.5 4 6000 1.2 4.1 1.7 6000 4 14 6 8000 1.2 3.5 3.2 8000 4 12 11 10000 1.2 3.5 3.8 10000 4 12 13 i.e. 1.2 mrad = 12 cm at 100 m i.e. 4 moa = 4.2 in at 100 yd

For reference, I made this "small" bullet database of 5.7 mm (0.224 in) bullets. The table is based on http://www.shootforum.com/forum/bulletdb.html , and there may be some typos. We all know the 5.56 AR-15 isn't a long range rifle, but still a good bullet is nice when trying to stretch its performance on those long range stages.

What would you guys say are typical muzzle velocities and ballistic coefficients of various .223/5.56 ammo? I’m primarily interested in factory ammo, but handloads are also somewhat interesting. Would like CHRONOGRAPHED data from an 18" AR-15 (or similar barrel length), since we know ammunition manufacturers usually use data from bolt rifles with pretty long barrels, which gives unrealistic numbers for our application. Also interested if anyone has data on how quickly and how much the muzzle velocity drops as the barrel wears out.

Tried to make an overview of all roll pins used on an AR. 1/16" x 1/4" (1.59 x 6.35 mm): Trigger Guard Detent Pin Forward Assist Pawl Pin (New round type) A1 Rear Sight Wheel Retaining Pin 1/16" x 5/16" (1.59 x 7.94 mm): Forward Assist Pawl Pin (Old teardrop type) 1/16" x 7/16" (1.59 x 11.11 mm): Ejector Retaining Roll Pin - (Btw, this size seems to be a rare special order type which is hard to find) 5/64" x 5/16" (1.98 x 7.94 mm), alternatively a 2x8 mm should fit: Gas Tube Retaining Roll Pin Charging Handle Latch Roll Pin 3/32" x 1/2" (2.38 x 12.70 mm): Bolt Catch Retaining Pin Forward Assist Pad Pin 3/32" x 5/8" (2.38 x 15.88 mm): Forward Assist Retaining Roll Pin 1/8" x 7/16" (3.18 x 11.11 mm): Type D Stock Sling Swivel Retaining Pin 1/8" x 1/2" (3.18 x 12.70 mm) Front Sling Swivel Pin 1/8" x 5/8" (3.18 x 15.88 mm) Trigger Guard Pivot Pin 1/8" x 3/4" (3.18 x 19.05 mm) Rifle Buffer Pad Retaining Pin 1/8" x 7/8" 3.18 x 22.23 mm Type D Stock Swivel Bracket Retaining Pin Hope I got that right. All these might not be used on a race gun, but here you have it nonetheless. Note that some aftermarket parts use different pin sizes. I think the image below sums up the most essential ones:

The competitor list has been released: https://rws2019.com/registered-competitors/ Here are some quick analysis based on the news. Major? Interestingly, it looks like about 10 of the Open shooters will be shooting Major, some of these being Tim Yackley and Trapr Swonson. This probably means some of the said shooters will be entering using .300 BLK instead of .223 Rem like the rest of the field. The American Women At the USPSA Multigun Nationals, Rebecca Yackley came close to Lena Miculek with 93.97% in the Lady Open division. While it's difficult to compare across divisions, I would however say that the 85.31% Overall that Ashely Rheuark accomplished in the Tactical division seems like a stronger performance. At the IPSC World Shoot they will all compete against each other in the Open divison, so if you ask me Ashley should be seeded as Number One in the Lady Open division. A strong team, at least! However, the Norwegian, Swedish and Russian teams should not be underestimated The American Juniors Riley Kropff (USA) won Limited division Overall at this year's USPSA Multigun Nationals, and may therefore be a favorite to challenge the reigning 2017 Junior World Champ Andrei Kalinin (Russia), still competing in the Junior category this year. The Overalls It seems like Daniel Horner and Josh Froelich will not be going (?), but Scott Greene and Tim Yackley are. When it comes to the Overall in Open and Standard, however: Sorry guys, either the Finns or Norwegians are going to take this. Or else I'll have to go and eat my hat! Also, I found it a little weird to see that Jerry Miculek has been entered as a Senior, since he should be eligble for Super Senior. Either it's a mistake, or maybe he's getting younger?

Capacity and reloads are the big issues for me. What if revolvers had one round per target? That would rougly half the number of reloads. Also, the point value for paper targets could be multiplied by two to drive the hit factors up.

It is confirmed that Lena Miculek is going. Irene Canetta is also going, She's the Lady Open gold medalist from the 2015 IPSC European Rifle Championship in front of Maria Gushchina. Irene also has two Open division Shotgun World Shoot silver medals. Will be interesting to see them all compete in the same division.

Seems like each of the biggest regions have been allocated 24 slots in the first round.

Why do USPSA have to specify a rule about not being allowed to carry magazine(s) in the mouth? And why does it not apply to Open, Revolver, Limited-10 and Limited? Is it only okay if you wear pink?? I am rolling on the floor right now..

And here's the link to Guns & Ammo: http://www.gunsandammo.com/editorial/a-history-of-pistol-mounted-red-dots/248367 1 1/4 inches is 31.75 mm, while 9×19 mm factory ammo seems to be specced to 29.69 mm. Did those extra two millimeters effectively ban 9 mm major, and for how long?

I think this is a misunderstanding. The IPSC rules clearly state that: 5.2.4.1 [Handgun] When a Competitor Ready Condition requires that magazines or speed loaders be placed on a table or similar, the competitor may retrieve and carry those items anywhere on their person after the Start Signal, and this will not be treated as contravention of Divisional equipment placement rules. The error might originate from another rule using some of the same words as your intro. 8.2.3 [Handgun] A course of fire must never require or allow a competitor to touch or hold a handgun, loading device or ammunition after the "Standby" command and before the Start Signal (except for unavoidable touching with the lower arms). 8.2.3 [Rifle and Shotgun] A course of fire must never require or allow a competitor to touch or hold a magazine, loading device or ammunition, other than a magazine fitted to the firearm, after the "Standby" command and before the Start Signal (except for unavoidable touching with the lower arms)

Here's a video from the 1986 World Shoot in Florida https://www.youtube.com/watch?v=oNK8Do5tRHg Difficult to see what guns they are using, but it looks like iron sighted 1911's. 1989 Steel Challenge: https://www.youtube.com/watch?v=kxfuKltuzME Seems to be some 1911's with sight tracker compensators. However, Steel Challenge might be a style of competition where irons sights are preferred due to increased speed on short distances, so it may not reflect the trend in IPSC at that time. Also, I have a hard time telling if the guns are single or double stacks.

Was that collimator sight one of the that look like an iron rear sight? That's the predecessor of Production Optics right there. Would like to hear when compensators started to get used in IPSC.

Here is a video from the 1993 World Shoot in England. At this point the Open guns look pretty much the same as now. Got me thinking about when double stack 1911 started to take over. This article from American Rifleman (https://www.americanrifleman.org/articles/2017/10/25/a-look-back-at-the-m1911-double-stack/) mentions the Para-Ordnance high-capacity frame being introduced in 1988. "At the time, the grand old M1911 pistol was rapidly losing the arms race among recreational shooters to double-stack pistols in 9 mm Luger. Hardly a month went by without a new, higher-capacity “wonder-nine” being introduced. [...] Carefully choosing a bumper pad for the double-stack magazine gave John Browning’s pistol the capability of holding 21 cartridges of .38 Super. When extended magazines were later approved for competition, capacity jumped to a “load-on-Sunday-and-shoot-all-week” 27 rounds."

One place to start looking can be USPSA Front Sight editions from the late 80's.

I believe that is not quite correct.. Back in the days, when men were men, everyone competed against everyone - there were no divisions. American Ray Chapman won the 1975 World Shoot using hist iron sighted .45 caliber 1911. A year later, the unknown Norwegian Jan Foss stole the gold from the now big favorite Chapman. Interestingsly Foss used a 9 mm single stack SIG P210, having the disadvantage of minor power factor, but the advantage of an 8 round capacity as opposed to Chapman's 7. (So maybe the P210 also should be allowed in Classic division?) Just to have mentioned it, the 1977 World Shoot the following year was won by Rhodesian Dave Westerhout using a single action, double stack Browning Hi-Power in 9 mm. I think open guns as we know them started to appear towards the end of the 1980's. Someone might have to correct me on this, but I think extended barrels with fixed front sights came first, then compensators, and lastly red dots. Believe single stack 1911 was the thing back then. What is certain is that the first to win a world championship with a red dot was Doug Koenig (USA) at the 1990 IPSC Handgun World Shoot in Australia. In 1992 IPSC introduced the Open division, becoming effective from January 1993. Then at the 1993 IPSC Handgun World Shoot in Great Britain, Canadian Matthew McLearn represented USA taking the first world Open division title.

According to this article from 7 January, Josh Froelich and Dakota Overland are preparing for the 2019 Rifle World Shoot. (https://www.womenandguns.com/dakota-overland-signs-with-jp-enterprises-for-2-more-years/ Dakota Overland Signs with JP Enterprises for 2 More Years) 15-year-old Dakota took an impressive third place in the Standard division Lady category at the previous Shotgun World Shoot. Recently her sponsorship with JP Enterprises was renewed for two more years.

Just heard that the first round of slot allocations were sent out to regions yesterday. Can't wait to see who will go!!

Mine is 3.3 kg unloaded, adding half a kilo for a full 30 rd mag the weight stops at 3.8 kg (that's 3800 grams). It's an 18" medium profile, but the iron sights saves about 500 grams compared to a scope, and means the rifle doesn't get so top heavy. Handles really nice.
