    I have been working with the MBC 98 Gr coated WC in .32 Long since Berrys has not seen fit to make any 83 Gr plated HBWCs for going on ten years now.

    1.6 Grs on N310 was too slow, 1.7 was right at 800 FPS (What I started out to get), and 1.8 Grs was around 830ish FPS. All using a Fed 100 SP primer. I had been hoarding the 2 to 3K I had left when they went AWOAL during the craziness for things that needed them, but since they have been available again lately I picked up 10K and have gone back to using them along with the other brands I have. I bought 10 S&B SP primers when Cabelas put them on sale for $20 per 1K just because it makes good sense to buy on sale. I also picked up 10K CCI in strips when Midway put them on sale for $20 per 1K, for the same reason, it makes sense. I hadn't used a lot of the CCI over the years for no other reason that they tended to be higher than Fed 100 and WSP primers in my area, the powder primer guy at the gun shows tended not to have them and the WSP shot well and took up less space than the Fed 100.

    After testing Saturday morning I had 12 rounds of 1.7 grs of N310/Fed 100and the MBC 98 Gr WC left from testing, and had the idea to try the S&B against them, so I loaded up 12 identical ones except for the primer and I used the S&B SP primer. I wanted to see how it affected the Avg FPS and ES/SD numbers, and get an idea if they grouped as well.

    I went to the range earlier today, set the gun and test loads out to warm up for awhile, shot three extra rounds through the gun and then shot two strings over the chrono at 5 yards with the target at 7 yards.

    I got sloppy (As I often do) with the S&B primered rounds so the group was a little bigger, but not different enough (If you throw out the one high I let go when the sights were up and the one I yanked low/left) to call one better than the other after just one group. I will test further by loading more of each and shooting multiple groups with each.

    The numbers from each 12 round group looked very similar, statistically indifferent I would say, and to close to say one is faster or one has better ES/SD numbers, considering such a low number of shots. A suitable substitute if further testing shows them to be as accurate.

    In another test with 9MM plinking ammo using 124 plated bullets, N320, and WSP primers showed the S&B SP primer to be slightly milder than the WSP, at least in that one application.

    Today:

    Benelli MP3-S, RP cases (.912 to .915), MBC 98 Gr coated WC, 1.7 Grs N310. OAL .960 +/-, 94 degrees 37% RH.

    Fed 100 Primers:

    Hi=815
    Lo=774
    Avg=801
    ES=41
    SD=10

    S&B Primers:

    Hi=820
    Lo=795
    Avg=807
    ES=25
    SD=7

    The operator behind the gun seams to always screw up a good thing, I've done it enough. Nice shooting, not sure primers made a difference.

    I found I can't shoot well enough to tell the difference in primers with handgun or 100YD rifle. But I rarely load at book max either. YMMV

    I am sure that is true for most of us, although occasionally it makes a noticeable difference.

    Had them both named Fed 100 primers, fixed it.

    I forgot to mention that the S&B primers are a bit tighter in the primer pockets than the Fed 100. I just re-primed the 27 cases a little while ago. I threw them in the primer tray all together and when priming the cases with the RCBS hand primer I could name which primer it was each time by the force required to seat it.

    Any thread about someone loading and shooting .32’s is a good thread! It’s a shame that cartridge family isn’t more popular... such sweet-shooting fun!

    I’m pretty much set on a 327 as my next gun. But I still keep looking at LC Smiths and Winchester model 70s. I know that I will keep loading and shooting my 32s for years to come.

    I have a decent stash of magtech wadcutters and a couple hundred LRN bullets left, but I am going to put a thousand MoBuCo wadcutters on my next order. I need some 30 carbine bullets and 38 spl wadcutters too, might as well save on shipping.

    AC, many handloaders have been reporting their S&B primers are more difficult to seat. I'm guessing it must be true, too many reports to be wrong.

    Thanks for all the info and photos.

    Hey, I have the same chronograph. I think that means we're related.

    Thanks for the detailed information. What were you shooting these loads with? All this shooting talk and no gun? That ain't right.

    Exactly. And no pictures either. Very disappointing

    Benelli autoloader. It takes WCs only, loaded nearly flush. I shoot them in my little Regulation Police as well.

    I fairly confident in saying that it could have looked like this and you’d still out shoot us with it

    Thanks, saw it on gunbroker many years ago and had to have it, haven't seen another one anywhere since. Paid nine hundred something, but worth it. Should have kept my Benelli 9MM I got for $300 locally, and sold too cheap. *Sigh* I have a handful of such "why the heck did I do that" gun selling/trading off stories.

    Could they be slightly different in size (as in a close, metric?)

    Unfortunately, if you are in this game long enough we all collect those stories. I wish I had a "stop it" button I could push when I'm about to do a stupid sale.

    Sir, that is the most astounding projectile-expulsion device I have yet seen. I had no idea there was such a thing. So it's kinda like a S&W 52, but for .32 Long? I simply must have one, even if I have to build it myself out of duct tape or something.

    Kinda sorta, yea. I'd like to have a S&W 52 as well, but can't bring myself to pay for one.

    I've never shot anything smaller than a .38special (in a Security Six)...well, excepting .22........so I have nothing to compare. Something wrong with that.....sheltered life, leaky roof. Nice gun. Would love to experience such a thing.

    My next one is going the other direction tho.........after all these years looking at it, I just need to see what the10mm is really all about......and there are some new ones out, sort of a resurgence.......and I've been researching what powder/bullet to use.....primers? I'm not that advanced. I showed my colors a couple of years ago when I bought a new CED M2 chronograph.....still unused:(....too many med. operations, and other fun things in life. Sigh. But at least I'm finally reloading again....will be able to handle pistol recoil again .... in one more month!

    Again, NEAT pistol!

    I expect to be able to shoot my .32s when I am old and feeble, that is one reason for having them.

    That's looking forward. O. & F. sneaks up on you too. :) No .25's in your life? I heard they were hard to reload.

    All it would take would be an interesting gun in .25 ACP. But yea, the tiny cases would be fun.......not. :)
