Looks for Target

Looks for Target (4/11)

  1. Interesting. I hadn't thought about possible damage to the blue tip. My primer issues are sporadic - maybe 1 or 2 per 1000 rounds - but they are VERY frustrating, as I have not found a way to clear them without removing the whole primer assembly from the press, and whenever I do that it (of course) spews the whole contents of the tube all over my bench. Lacking a 3D printer, do you know of anyone who makes such a tip protector? Bruce
  2. I have an RL-1050, and I'm sick enough of the endlessly-creative ways my primer system likes to puke that I'm thinking of selling it and getting an 1100. How much of the 1050 "stuff" I currently have will work on the 1100? For example, are the toolheads compatible, or would I have to replace them? Same question for shellplates, powder-drops, casefeeder heads, etc, etc, etc. Thx Bruce
  3. Have a home-built PCC that has run fine for years. F1/QC10 receiver set, JP everything else (barrel, trigger, bolt, SCS buffer) Built a new PCC a couple of weeks ago, and it ran great in testing, which of course meant it barfed when it heard a "beep". 3 times over the course of a dozen stages, it fed more than one round - which resulted in a mess in the chamber. One round nosed into the chamber with another round wedged above it against the ceiling of the upper. New PCC is an R&R barrel (ramped 8" barrel with shroud to make it legal length), SI bolt, Blitzkrieg buffer... and except for those things, identical to the above (same receiver set, same buffer tube, etc). Also, same ammo. And same mags (MBX tubes with an assortment of MBX extensions) One thing I have in my head is that - I think - each of the three malfs occurred at a port with low/close targets behind it, which means the PCC was pointed down 45 degrees or so. I'm wondering if somehow the weight of the mag is rocking it forward, changing the relationship between the top round and the bolt. But... it's an identical receiver and the same mags, so I'm not sure why it would happen with this one and not the other. Any ideas?
  4. Hmmmm.... okay, I did some digging and I think I've convinced myself that a "good" BC is .... not particularly meaningful. I called Montana Gold and asked if they had a BC, they said "no, we never did that, because those bullets are only meant for pistol distances". They did say that the BC for the Hornady 124gr XTP should be fairly close. I found BCs for the XTP and a couple of other 124gr JHPs from a number of manufacturers, and at the velocity I'm running, the calculator says they all peak at 60y, and POIs are all within 1/3" at 100y. In case there are other number-geeks among us, here is the data I came up with (using 1140fps): Sierra 125gr JHP / BC = .137 / peak rise is 3.5" at 60y / hits 0.5" high at 100y Winchester 124gr JHP / BC = .142 / peak rise is 3.5" at 60y / hits 0.6" high at 100y Sierra 124gr JHP / BC = .157 / peak rise is 3.5" at 60y / hits 0.7" high at 100y Hornady 124gr XTP / BC = .165 / peak rise is 3.5" at 60y / hits 0.8" high at 100y So, I think I have a "good enough" answer. (It's not like i'm going to hold - off-hand - to 1/3" accuracy at 100y anyway...) B
  5. Anyone have a (good) BC figure for the Montana Gold 124gr JHP? I have a load I like, I have a good 15-yard zero, I'm curious what the POI will be along the way out to 100y.... and it's raining, so I don't feel like going out and hanging targets right now.... Yeah, I know, I know, it's not really a distance platform.... but... whatevs. My old load with a 15y zero was "on" at 100y, and no more than 3" high at distances in between, which has sometimes been handy to know.
  6. I usually run 12-round strings and count them all (including the cold-bore shot, which usually ends up the low velocity of the string) Spreads are... pretty good. Across 12 rounds with the 124gr CMJs, extreme spread was 38fps, SD = 9 Same load but using 124JHPs, extreme spread was 28fps, SD = 7. Which is nice, but I'll have to do some testing to see if there are any issues feeding the JHPs. Edited to add, just out of curiosity I used to run 15-round strings, and toss the extreme-low and the two extreme-high velocities.... thinking that would give me a better idea of the real-world average. Turns out that the resulting averages and SDs for the remaining 12 rounds were almost identical to the results if I just shot 12 rounds and counted them all. (#NotAStatisticianAndICanProveIt)
  7. Standard JP 16" (14.5" + pinned muzzle device) ....although I'm currently giving a long look at that Taccom ULW.
  8. OK, I loaded some stuff yesterday and took it to the range today. I "think" I have a new load (*) With 4.2gr of N320 under a 124g CMJ, I got an average of 1053 fps, for an average PF of 130.6 (PF for slowest round was 130.2) I also tested some loads with 4.3gr and 4.4gr of N320. Didn't like the feel, they were VERY dirty (a little more crimp might help that), and on the 4.4gr set, got slightly flattened primers. All for about 30fps, which doesn't seem worth it. So... I think I'm settled on 4.2gr. I like the feel, plenty accurate, pretty low spread across a 12-round sample.... the only thing that gives me pause is that there isn't a lot of fudge room in the PF. (*) So.... today's question is... how close is too close? Is 130.6 enough buffer over the shoot-for-no-score line, or should I work up something that runs a little faster? My Open 9-Major load usually runs about 169-170, which gives me about the same buffer... except if something weird happens and I drop 3% at the chrono, I'm still in the game, just shooting minor. If I drop 3% with this load, I'm flirting with a big fat zero.... Thoughts?
  9. Hmmmm... N320 and 231 are practically right next to each other on the burn-rate chart on my wall. Unless I'm mis-reading it.... To the rest of your comments, yeah, totally agree, with the addition that I want them to feed, and go bang when I pull the trigger. Both of which have been problems lately. I use a JP SCS buffer, and can tweak the weights to give the recoil-feel and dot movement. B
  10. Maybe . If I could get the 130gr Fed Syntech bullets, I'd use them. But they're unobtanium... and I'm sitting on a garage full of Montana Gold 124JHPs and 124 CMJs, so it seems silly to go out and try to find different bullets, especially in the middle of a components crisis. I did try some 147s and really didn't like the "ker.....chunk.... feel of the action.
  11. How do I get my "MoM badge back? I edited my signature to update the email address, and it wouldn't let me save the change with the picture included. I think it was October 2006, but not positive.... Thanks! Bruce
  12. So... I'm finally breaking up with the factory ammo I've been shooting for the last couple of years. It's not me, it's you. Couple of years ago I worked up some test loads. 124gr MG jacketed round-nose over 4.2gr of N320 with a winchester SPP. Ran fine. Problem is, I have my PCC dialed in for the current load, which runs at about a 145 power-factor, and really like the way the gun feels right now,. I just don't love the ammo anymore. Irreconcilable differences. Test load ran about a 132pf. Which presents a dilemma. Should I bump my load up to (maybe) 4.4gr of N320? That should, in theory, end up around 140pf Or should I start over from scratch, build a load that runs, and then do all the things (reconfigure my buffer, etc) to get the feel I want. I looked through all the PCC / N320 / 125gr loads in the threads here, and most of them seem to cluster between 3.8gr and 4.2gr. Didn't see any above 4.2gr, so I'm wondering if that would push the gun (bolt, buffer) more than is good. Other options might be to switch to TiteGroup, but I have a bunch of N320 and like it for other 9mm loads, so I'd love to make it work here. Open to input... Bruce
  13. Generally true. It varies from place to place, but in general a Section is formed when there are a number of clubs within a geographic locale that want to work together (coordinating calendars, bringing in RO seminars, pooling activity for Nationals slots, etc). Each Section is required to have section bylaws that specify how the Section Coordinator is elected, and how slots will be distributed. I have 12 Sections in Area-1, and I think all 12 of them elect the Section Coordinator at the club level - each club-representative has one vote in the process.
