It was another beautiful day in paradise at the range. I planned to go to the range on Thursday when it fit my schedule, but there was a nasty (North Koreanish) storm cloud that hung out menacingly to the south of the island so decided against visiting the range then. The forecasters said today the winds would pick up this afternoon so got there at mid-morning. As it turned out, it was dead calm with no rain in sight. With all the rain we’ve been having, the range is starting to look like a family park.
6.5 Creedmoor: I was looking forward to trying the rifle again after discovering the action screws were loose last time. I happen to arrive at the range the same time as my friend, Shaun. He bought the same rifle a couple weeks after I did. (I finally received my rebate check from the manufacturer.) He was telling me about how his rails were loose at his last trip. After shooting 7 fouling rounds, I discovered that my rails were loose also. We didn’t have any Loctite and I told Shaun that I was gonna tighten the fuck out of it. (Very scientific.) I torqued it to 45#. Later I’ll take it apart because I bought better scope rings and plan to lap them with the Wheeler kit.
I made 5x7 rounds of Superformance 42.0gr with seating depth of 2.810” to 2.840” in 0.005” increments. Nosler recommends 2.805” OAL, and I previously found 2.830” more accurate. I don’t have a bullet comparator and this was the best I could do (or interested in doing). I have a bottle of IMR8208 XBR that is burning a hole in my reloading bench, so I need to start loading that. I have 353 of the 140gr RDF bullets remaining. After that, I ordered a 500 box of 140gr Hornady Match BTHP that has great promise. At 24 cents per bullet, these have been flying off the shelf.
What’s weird about the seating depth test is that the loads I shot on the right side were more accurate than the loads on the left. There was something neurological going on with my shooting. I know it’s cheating, but I excluded one flyer from the left side per load. It’s the best way I could try to make sense of what I had. In addition, most of the loads exhibited the annoying characteristic of having an inverse relationship between group size and velocity SD. The 2.815” grouped well but that may have been a fluke. I guess I’ll go with the original 2.830” based on the eyeball test and call it a day for now. I’ll try it again later with the I8208 XBR and then try the remainder of the Superformance with the new Hornady bullet.

I had 15 cases left so I made 41.6, 41.8, and 42.2 gr of Superformance. The 41.6gr grouped best, but I feel like it’s not conclusive. Most of the 42.0gr rounds I made were spent on trying to figure out the problem with my scope rails or I shot them at the metal target.
MN 91/30: I started out with shooting the Xtreme 123gr with 48.5gr Reloader 15. These packed a wallop at 2915fps and kept blowing the sunshade off my chrono. I think the display had some water in it from a couple weeks ago, and these rounds were the Coup de Gras for the display. They were able to hit paper and that’s about it.
I next shot 25 rounds of IMR4895 38.2gr with the Hornady 174gr RN that worked well for me before. I shot them in 5 round groups and averaged the results. These shot so well, I listed the results in MOA instead of inches at 50 yards. Despite the SD, the velocities were spot on with the Hornady load data.

Next were 10 test rounds of H4198 29gr with the Hornady 150SP that was suggested to me. I had to raise the scope by 4 minutes. As the story goes, H4198 and Unique are not positional dependent powders in the cases. In fact, I recently found an Iraqveteran8888 video where he suggested 13 to 15 gr of Red Dot with the jacketed bullets. The H4198 were surprisingly accurate. There’s no published data that I could find so no idea how fast these are supposed to go. Probably not a good velocity for hunting…

Next were 28.0 to 30.0 gr H4198 with the Hornady 150gr SP. The 28.0gr grouped well with excellent velocity SD. The 29.5 and 30.0 gr elevated off the target so these results are unreliable. I’ll try 27.6 to 28.4 gr next time but will need to obtain a new bottle.

1911-22: I replaced the firing pin spring and the recoil spring on the pistol. It shot a lot better than before and should’ve replaced the springs earlier.
