I think this is appropriate to this topic. Ruger just sent this out yesterday. I do have to admit, I think the Super GP100's that I saw the IRC looked pretty dang sexy! One of the Team Hogue shooters was using one during the man-v-man shootoffs on Sunday and after some screaming fast strings remarked some to the effect, "Don't tell me that you can't run Rugers fast!": Team Ruger Doubles Up on Divisional Wins at the 2021 International Revolver Championship Congratulations to Team Ruger members James McGinty and Dave Olhasso on each taking home a divisional win at the 30th International Revolver Championship this past weekend. McGinty won the Limited division and third overall with a final time of 273.62 competing with his Ruger Custom Shop® Super GP100® Competition revolver chambered in 9mm Luger. Olhasso won the Limited Six division with a final time of 312.03 shooting his Ruger® GP100® six-inch revolver chambered in .357 Magnum/.38 Special.

I would suggest drawing a rectangle on a piece of paper the size of the box and laying the SP101 and see how close it is.

Does one of this apply to the factory Glock MOS plates?

I'm loading on a Dillon 550b with a Dillon powder measure. I'm going to try 3.5 next (after the IRC's next month)...or just use SNS bullets instead.

I have some additional load data results. All are for 3.4 grains of Alliant e3, primers are Federal 150's in Starline brass. OAL is 1.250. First up is 230 Blue Bullets in my 625JM 4": Stats - Average 690.19 fps Stats - Highest 709.83 fps Stats - Lowest 670.5 fps Stats - Ext. Spread 39.33 fps Stats - Std. Dev 13.69 fps Power Factor 159 Total number of shots 12 Next is 230 SNS red coated bullets in the 625JM: Stats - Average 708.99 fps Stats - Highest 741.08 fps Stats - Lowest 681.36 fps Stats - Ext. Spread 59.72 fps Stats - Std. Dev 17.42 fps Power Factor 163 Total number of shots 12 Note - SNS coated 230 grain bullets are 19 fps faster on average than Blue Bullets. I was surprised by this difference. Finally, just to see, the last is 230 grain Blue Bullets from a Glock 30S (this model has 3.78 inch barrel with a G36 narrow slide): Stats - Average 649.41 fps Stats - Highest 678.67 fps Stats - Lowest 620.07 fps Stats - Ext. Spread 58.6 fps Stats - Std. Dev 20.09 fps Power Factor 149 Total number of shots 10 Looking through the individual power factor on the Blue Bullet loads, 3.4 grains is skating awfully close to the 155 PF minimum for IDPA with 5 out of 12 coming in just below 155. Every shot with SNS made PF with 34 grains. Needless to say, I need a totally different load for the G30S to get to 165 if I used it in CDP....but more than likely I would use it in CCP and am positioned really well since 125 is all that is needed. Also, I'm in really good shape with these loads in the 625JM for ICORE's IRC next month. Hope all this is helpful.

I wasn’t trying to squeeze out the best groups at 25 yards (off of a rest) but e3 was definitely an improvement after I fired the first 12 rounds of WST. I was actually impressed considering I wasn’t trying very hard.

I just got back from the range and tested three different loads with e3 along with my current load of WST. All are through my S&W Model 625 with a 4" barrel and using Blue Bullets 230 grain roundnose. Primers are Federal 150's in Starline brass. OAL is 1.250. The chronograph is a brand new Labradar that I got as an early birthday present from my wife. Woot! Woot! First is my current load of 4.0 grains of Winchester WST. From Labradar today: Stats - Average 701.52 fps Stats - Highest 725.46 fps Stats - Lowest 664.08 fps Stats - Ext. Spread 61.38 fps Stats - Std. Dev 17.51 fps Power Factor 161 Total number of shots 10 This load was also chornographed at the Midwest Regional ICORE and PF was also 161 (I did have the highest PF at the match Same load (4.0 WST) recorded with a Shooting Chrony - June 11, 2020 with an average velocity of 708 fps, SD- 16, PF-163. So pretty close results between the two chronographs. Now for the e3 results. Same bullet, primer, case and OAL. 3.3 grains of e3 (this weight of e3 was dispensed from the Dillon powder measure that was set for 4.0 grains of WST....so, volume-wise, 3.3 grains e3 = 4.0 grains WST). Stats - Average 682.17 fps Stats - Highest 701.92 fps Stats - Lowest 661.58 fps Stats - Ext. Spread 40.33 fps Stats - Std. Dev 13.16 fps Power Factor 157 Total number of shots 9 Four of the 9 shots the PF was below 155, the other 5 were over 155. This is cutting it too close for IDPA sanctioned matches but will do nicely for ICORE. 3.7 grains of e3: Stats - Average 772.77 fps Stats - Highest 809.57 fps Stats - Lowest 756.31 fps Stats - Ext. Spread 53.26 fps Stats - Std. Dev 13.19 fps Power Factor 178 Total number of shots 11 3.9 grains of e3: Stats - Average 794.79 fps Stats - Highest 803.68 fps Stats - Lowest 787.71 fps Stats - Ext. Spread 15.97 fps Stats - Std. Dev 6.63 fps Power Factor 183 Total number of shots 4 Note that all e3 loads were in batches of 12. I rushed some of the shots too soon for the Labradar (you're supposed to wait 2 seconds between shots and I know I didn't wait long enough between some of the shots. The last load with 3.9 grains only 4 shots were registered. Shot number 5 was a squib that lodged the bullet in the barrel. Luckily I couldn't pull the trigger or cock the hammer. I didn't realize it was a squib. In the thousands of rounds I've loaded on the Dillon 550b, this is my first squib. I've read elsewhere about e3 bridging in powder measures. I'm going to pull the remaining 7 cartridges with e3 and see if there are any double loads. I could have very easily screwed up while loading and not have it been an issue with the powder measure but this does cause me to pause. All said, if there isn't a double load (which would mean that the powder didn't bridge) then I will probably start loading 3.3 grains for IRC in September. If I use this revolver in a sanctioned IDPA match I will goose it up to 3.4 grains to give me a little more cushion in the power factor. The other plus to 3.3 grains of e3 is that if I can find WST and decide to change back, the powder measure is ready to go. Hope this info helps others.

Thanks!

That sounds like a great place to start!

I just picked up a pound of E3 after reading all the good news here. Any recommended loads for 230 Blue Bullets out of a S&W 625JM with a 4”. My current load is WST that I’m almost out of and E3 is available (and sounds like it could even be better). I use a Dillon 550b with a Dillon powder measure (small bar) and have read some have difficulty with consistent charge weights so I will watch for that. Any help would be appreciated. I’ve Googled a lot (actually Duck-Duck-Go) but am hoping for a more definitive answer. Thanks!

OK, so I thought "Heck, I should just take a picture of my Shield with both magazines sitting on the PDF so you can see"... so here it is. The green box is the BUG box. The Shield is a snug fit with the shorter flat basepad magazine. It's clearly too tall with the extended magazine. I haven't checked the height since I changed the sights to Trijicon HDXR's. It's snug but fits with the shorter magazine...

Let's help the original poster with the pertinent parts of the rule book for his question: Size requirement (size of box): From page 31: 8.2.8 Semi-Automatic BUG (BUG-S)Handguns permitted for use in BUG-S must: F. The firearm with the largest magazine inserted must fit in the IDPA gun test box measuring 6 1/2" x 4 5/8" x 1 3/8". The S&W Shield is too tall with the extended magazine but fits with the flat basepad magazine. Regarding the base pad with the little pinky extension. Don't know how tall the gun is with that installed (has to be less than 4-5/8") but having the base pad is legal, as long as it fits in the box, based on BUG-S being able to follow the ESP rules. See below: 8.2.8.2 BUG-S Permitted Features and Modifications -Semi-automatic BUG must comply with all ESP features and modifications,and equipment restrictions. From the ESP part of the rule book on basepads: 8.2.3.2CDPPermitted Features and Modifications (Inclusive list): DD.Aftermarket magazine base pads may be used provided they do not make the magazine weight more than 1.50 oz.over the same capacity factory magazine. EE.Magazine base pads may be modified by reshaping, texturing, or adding bumper pads provided that they do notmake the magazine weigh more than 1.50 oz.over the same capacity factory magazine. FF.Magazines that are longer than stock may be used provided they meet all other division requirements. I'm attaching a PDF that I hope is helpful. It's diagram shows the different size boxes for the various categories. If you print it via Adobe and select 100% size (do NOT print to fit) it should come out right. The sizes of the boxes are listed so check the box size with a ruler to just make sure it prints out correct. It also shows that maximum barrel size, width, and the number of "LDC" or Loading Device Count AKA magazines or speedloaders. Hope it is helpful to you. IDPA Box print (2020_08_20 21_07_27 UTC).pdf

I should add that modifications to BUG-S have to follow ESP rules and base pads are allowed as long as the gun fits the box.

As long as the height of the gun is less than 4-5/8” you’re OK.

It’s too tall with the extended magazines. I bought flat base magazines so I can use it in BUG.

And Merry Christmas to you, too!

I had TK chamfer my 625 cylinder and, OH BABY!!!, that makes a huge difference! Prior to having that done the cartridges tended to hang up in the case mouth. Now it’s like a shop vac sucking them into the cylinder (ok, it’s just gravity, but still...)!

If you get a Dawson verify that the front sight fits correctly in its slot. Mine (also a G34 Gen5 MOS) did not and would rotate from about 11:00 to 1:00. I did contact Dawson and they said to fill the slot with Loctite. That shot loose so I wrapped the tab and n the bottom of the sight with dental floss and Loctite and it worked so far.

Based on the advice of the great folks at UniqueTek I tried their Ranch Product 45 ACP moonclips making certain that the smooth side of the clip was against the rim and the stamping curl was pointing towards the bullet end and it works great. Some of the clips were difficult to impossible to used if the clip was flipped the other way. Who knew? (Ok, probably all the Ranch Products fans on this thread). Sent from my iPhone using Tapatalk

Ranch Product users, are your moon clips flat across the surface? Mine have a lip around all the edges as though the punching die may have been worn. The result is that they are effectively thicker than they should be. The TK Custom clips are smooth all the across the face of the clip without a lip on the edges. I filed the lip off of one of the clips but it was a pain. If your Ranch clips are smooth I will contact Ranch and see if there is something they can do. Sent from my iPhone using Tapatalk

The moonclips that cause me problems came from UniqueTek. Sent from my iPhone using Tapatalk

No problems with brass. I do use a BMT mooner/demooner because it’s way sooo cool! Sent from my iPhone using Tapatalk

I use nothing but TK Custom. I bought a large of inexpensive poorly stamped moonclips and they would bind the cylinder. No issues with the TK’s. Sent from my iPhone using Tapatalk

I’m really tempted to get a new Python and see how it compares to my 625JM. All else fails, it would be a good excuse to get a Python. Sent from my iPhone using Tapatalk
