    Bad SD and ES but good group...

    Yes, I've been sorting to a range off .02 gr. That as fine as my scale will go. When I first started weighing primers, I wasn't sure just how wide between the highest and lowest would be. And initially, I wanted to test what kind of difference there might be, if any, between the lightest and...

    Bad SD and ES but good group...

    I don't approach it by selecting any particular weight or weight range. What I want are those primers of the same weight or close to the same for any batch of cartridges loaded. It's when their weights are far apart that I will see a difference. Like in the picture below there were those that...

    Ugly reloading precision primer seater

    The best tool I've found to get consistent primer seating is the Lee ACP Bench Priming Tool. It doesn't seat off a case's rim. It seats off the base of the case the same way you'd measure the seating depth. It isn't designed to be adjustable, but there's an easy fix for that. It's my primary...

    What did you do in the reloading room today?

    Which SIG 277 headstamp is on it? There are different ones that have different case volumes. That's why I was asking. Like I have some stamped with "277 SIG FURY" that have a case capacity of 57.7 grs H2O. Another batch I have is just stamped with "SIG 23" having 56.8 grs of capacity and...

    Bad SD and ES but good group...

    I only reload for to calibers . . . .308 and 6.5 PRC. My SD's run between 4 to 7.5, the higher number typically do to a higher number of shots, like 20 or more. When fire forming some new .308 Alpha brass, using my best load that I've been using, got an SD of 6.2 from 80 shots. On another...

    Hmmmm??? That's a .308 case with 54.8 grs H2O? If so, what's the head stamp on those?

    What did you do in the reloading room today?

    With these SIG 277 hybrids, one can get 300 win mag velocities from a .308. For someone with only a .308, it might serve a hunting purpose for a particular situation??? On the other hand, some people just like to hot rod. ;)

    Bad SD and ES but good group...

    I always want good SD's (ES's will follow suite) as I've always said before . . . it's what tells me whether I'm loading my cartridges well nor not. But SD's don't tell me which load gives me the best results on targets. It's the targets that tell me what the best load. But yes, you can't...

    What did you do in the reloading room today?

    Right. That solid steel portion where primer pocket and flash hole are isn't being sized. It's that portion above that's been blown out .002" and is taking more force to size it back down. Yes, I do anneal necks and shoulder area, per what I mentioned above. I don't anneal to dead soft, so I...

    6.5 PRC Loads

    I think you can find them in Remington 700's, Howa 1500's and the Tikka T3/T3X's. And I'm sure there's plenty custom actions as long as they and the stock are cut for an M5 inlet.

    What did you do in the reloading room today?

    Looks like the steel cases was a challenge to size??? :unsure: After my first firing this little batch of SIG 277 Hybrids, I wasn't sure what to expect on this second sizing. . .especially as most were fired pretty close to 80K psi. I noticed that it took more than normal effort to seat the...

    Garmin C1 chronograph

    I was happy to find that the data now downloads into an Excel file and any number of sessions can be downloaded at once into just one file (used to have to do it into individual files downloaded separately) and when more than one is selected for download, each session is separated and labeled...

    6.5 PRC Loads

    No. They're a metal box magazine compatible with AICS pattern bottom metal, which came with the rifle (an RPR).

    6.5 PRC Loads

    I think he simply made a typo as he said he's going to load to 2.995 when actually referred to mag length as 2.955. huh? The short action mags I have accept 2.975 OAL's. :)

    6.5 PRC Loads

    The only "headache" you might have with those long bullets at 2.955" is that their bearing surface will be in contact with the area where the donut develops. So, as you reload, you'll need to keep an eye on that and find a way to mitigate it. And since these long bullets will be somewhat deep...

    Garmin C1 chronograph

    I've had one since they first came out . . . ~2 years ago. There was a couple software hiccups reported to start with, though I never had a single issue since I got mine. Previously, I had a MagnetoSpeed, which I tested my Garmin against and also with the popular LabRadars that some shooting...

    Case sizing with mandrel - seating issues

    Yes, I meant "shouldn't". . . and made that correction. Thank! :) You're right about the problem with squeaky clean necks when wet tumbling with SS pins. Lubing in that case, I would say is a must. However, when wet tumbling without pins, for a short time to clean the outside nicely, leaves...

    Bad SD and ES but good group...

    The thing I look for in horizontal stringing is that they're on or close to being right on the same plane. In other words . . . consistent vertical location. How far apart horizontally can be from various things not having anything to do with the load (eg. how you pull the trigger, wind, how...

    Case sizing with mandrel - seating issues

    . . . therefore, wet tumbling the very first thing before sizing make sense, AND. . . the outside of the brass is nice and clean so that your lubing is more effective for sizing. Yes, dry tumbling works just fine at removing the lube. BTW: when expanding your necks with a mandrel, you...

    Little Crow Gunworks: Avg POI Is More Important Than Group Size. Thoughts?

    This is one of the things I noticed and, as I so often to, ran an experiment of some range brass I picked up. I changed speeds in how fast I rammed my cases into the sizing die and measure to results. The results changed with the speed, like faster resulted in more springback and less...
