    Ehh, don't bother...

    Various 175 gr .308 bullets compared to the GP11 projectile
    Great, thank you. I will print that out. I think I have some Berger Juggernauts I can compare with as well. It sure is a different beast isn't it!

    And why does not someone duplicate it?

    It is possible the Nosler RDF comes closer to duplicating the GP11 bullet. As you can see, the Barnes Match Burner is closer than the Nosler CC or Sierra MK's.

    berdan decapping method.

    picture 1: berdan/swiss gp11 used primers
    picture 2: rcbs depriming tool/handle/allen wrench
    picture 3: locking screw for depriming pin
    picture 4: allen wrench to losen or lock depriming pin
    picture 5: allen wrench in depriming pin which can increase or decrease pin depth
    picture 6: brass holding handle
    picture 7: brass on holding handle
    picture 8: soft foam for handle while depriming....after 100, fingers get sore.
    picture 9: use depriming tool like a bottle opener.. requires a little bit of force.
    picture 10/11: deprimed berdan cap and caps.

    It is possible to seat the depriming pin to deep and break the pin... the key is to start shallow and give it a 1/2 turn and retry.. Once its at the correct depth you are in business. You will have to lock and unlock the pin each time until the correct depth is obtained. Don't get greedy, go slow. Moderate force is require to pull the primer out. A bit more than opening an IPA beer with a bottle opener. Pins are available and I have broken one after 1000 pulls. No biggy. You should get a 99% depriming rate, or more.

    If you look closely at the GP-11 bullet, and even better, at the drawings for it, you will see a very unusual feature, apart from the long boat-tail.

    The ogive is of secant form and starts immediately forward of the cannelure. There is almost NO parallel bearing surface on the entire bullet.

    Thus, ANY "ersatz" bullet MUST have a similar secant ogive form. Especially if you are feeding a K-31. WHY?

    Unlike the earlier K-11, the K-31 has a VERY short throat, specifically designed to work with the GP-11 bullet.

    The 1911 models have a LONG throat designed to work with the earlier, "torpedo-shaped" GP-90 /03 ammo as well as the "new" GP-11. By the time the K-31 was introduced, there probably was no need to accommodate the ancient GP-90 ammo.

    Thus, the short K-31 throat MUST be fed with secant ogive bullets, not tangent-ogive stuff like the Sierra style.

    I use the locally (Oz) made BJD HBC 155 grain, secant ogive jobs, because they WORK and I also use them in my "full-bore" .308" target rifle, in which they also work very well.

    I picked up some of the Nosler 175 gr .308 RDF's. Very similar to the Barnes Match Burners

    I noticed the meplat is much smaller and more uniform than the other bullets

    Various 175 gr .308 bullets...


    Sierra MK, Nosler Custom Comp, Barnes MB, Nosler RDF

    RCBS berdan depriming tool is basically a pry bar and is horrendously expensive. Really not necessary any more. Even for 7.5 Swissicon. Graf's carries Boxer Prvi brass at $29.99 per 50. $37.99 per 25 for the over priced Norma stuff.
    No$ler everything is over priced too. If you want a 175 grain match bullet, Sierra makes a regular Match King and a Tipped MK. Hornady makes a 178 grain Match and ELD-Match. Use 175 grain data.
    Spelling and Grammar count!

    I've been using Prvi brass for reloading, but have thousands of rounds of GP11 brass.

    I was able to buy a 500 piece box of first quality 175 gr Nosler RDF's for $130 shipped, so they are not terrible expensive.

    I've got some good results with the 168gr Sierra Tipped Matchking which is a secant design. At an OAL of 3.06" they're just touching the throat of my very tight bored K31icon. I got a good string of 10s shooting from 300yds on the MR63 target (5.85" circle) using an old Noske 2.5X scope last match I shot in.

    I got some good results with the Sierra 175 match, picked up in bulk.

    A shade under 1 MOA. Deep seating was what worked. Have to look up the COAL I set them to.
