The PN is : 30508. Yeah, I don't know why you would make a bullet .5 grains heavier.
Also, I did the mod. that you have done to shoot longer O.A.L loads. I am using a C.O.L of 2.400 like you, but using Winchester primers.
I thought you might have mentioned that before Hapa, but I couldn't remember. Besides the 140gr Monoflex bullets, I also got some Hornady 180gr SPFB's to try. The results with the 180gr FB Noslers that Zooka sent me looked promising. I also got some 165gr DeepCurls to try, though they hopefully aren't as at odds with the caliber as the 165 HotCors. Seemed like I could not find a good load in terms of accuracy for them no matter what I did. Zooka warned me about them, but I had to see for myself. It doesn't make sense that a particular bullet will not find a happy load in a give caliber. I'm the eternal optimist, believing that every bullet can be made to shoot well in a caliber, if you find the load it likes. Since the HotCor 150s shoot so well, you'd think it wouldn't be such a stretch to get the 165s to do the same. I've yet to try anything in either a 170 or 175 either.
It's really starting to look like if you're chasing good groups, you almost have to be content with velocities in the .308 to low .30-06 range. Not that that's a bad thing. those calibers have taken plenty of deer. In that velocity range, there are plenty of accurate loads out there. I've been sifting through all my targets and have started my own little list of the loads that shot accurately, regardless of velocity. There are quite a few actually that shoot sub-MOA in my past efforts. They just didn't do so at really hot velocities. Which brings me to AR-Comp powder. It's like the perfect match for this caliber in terms of velocity versus pressure versus using all the case capacity, but for some reason, I've yet to find a consistently
accurate load with it across several bullets that shoot accurately with other powders, even when I load them ahead of AR-Comp to match the velocity that they shoot accurate with in those other powders. To me that is perplexing. It'll be interesting to see what these 180s shoot accurately with. Ditto on the Deepcurls, though I suspect they will behave the same as the HotCors in the same weight. Some folks maintain that they are the same bullet, just renamed to spur new interest. With the Monoflex's, I don't know what to expect from them, though their form factor looks suspiciously a lot like those 160gr FTX's that I could not get to shoot accurately a while back. Lots of work to get done before the weather turns uncomfortable, especially considering that I'm still experimenting with two other calibers at the same time.
We almost finished rebuilding the rifle range superstructure today and should finish for sure tomorrow. That project cost me two weekend's worth of shooting and of course, both weekends had beautiful weather in the 70s. Go figure...
I did prep another bag of 25 WSSM brass to where they're ready for loading. So, the next few week's work will be with fresh brass. The last batch were starting to look the worse for wear and tear and every session yielded a split neck or two. Seems like 5 loadings are about the operational life limit for this caliber. I actually bought two bags of brass in a sense. Unlike the previous two bags, the one I got last week had like 12 bad cases, with folds and wrinkles in the necks especially, but many were in the area where the neck transitions to the shoulder. I actually took them back to my reloading store and despite the owner acting all put out about having to exchange them for another bag (from the same lot), that bag only had two bad ones. I could not believe what Winchester let get out of the factory. That's like one bad case in every four. Now perhaps I've lived a charmed life so far, but I've never seen such a bad effort from any manufacturer as those were. The reloading shop owner tried to get me to send them back to Winchester, claiming that they reimburse you handsomely for your trouble. I told him "That's why I pay you $38.00 a bag for what I can get cheaper by mail order. You send them back."
As always, I'll report my results. If you look at the activity on the WSSM Zone sub-forum, compared to more interesting ones like "What's your favorite Taco, Car, Band, Movie, Medieval Sword, Tacticool Sling, Cheese-Grater Forearm, etc. I swear there are but a few of us working to further the state of the art. That's a "lot of oyster and not enough pearl."
