    I shoot most my elk under a 100yds, but occasionally a shot presents itself at long range. To be more versatile I'm considering ditching the swift A-frames for a more aerodynamic scirocco bullet.

    I need to be sure that this scirocco bullet can stay together on close shots through heavy bone as flushing timber elk don't always present ideal shot placement. .338RUM is pretty fast and I've had nosler partitions completely peel off the base leaving just a nub so thats why I switched to A frames and they have held up. Would a Scirocco???

    Assuming it will, I need to develope a load that I can use and have a custom CDS dial made for my Leupold. My first attempt is going to be remington primers, nosler brass and reloader 22. I'm hoping to find accuracy at about 3,200 -3,300fps. If the reloader22 doesn't produce a winner, what would you try next?

    My experience with Scirroco's is you can't destroy them, but flattened out like a washer they don't offer deep penetration. Take a look at the Hammer's. I think RL 22 will give good results.

    The Hammer 213 will do what you want, but the Sledge Hammer line while heavier, is profiled a little better in close.

    You offer great insight, I hadn't thought this through. I watched my uncle zip 3 of the first Barnes bullets through the chest of a large bull elk. That thing ran forever, field tip arrows would have left better wound channels. I swore off copper bullets that day which was over 25yrs ago!

    Perhaps I need to reevaluate the copper slug, because they do offer the penetration and long range performance I am after. I don't know if they will put the "smack" on an elk like lead, but they are probably better at saving meat which is a huge plus... I will try a box, thanks!

    I swore off the copper as well due to issues of bullet hardness. Steve is very serious about bullet material, tolerances etc. Give him a call very receptive to questions, offering sample packs, and guarantees.

    I haven't had opportunity to put one in an animal yet, but they shoot good, and that's what we all had chambered if opportunity presented its self.

    Still some good lead based bullets out there.

    7828 did well in my 338 rum with 200 AB and 210 Partititons I used 93 grains and 215 primers. RL22 didnt do so well grouping. It shocks me you said you stripped a partition. The partition is an a-frame bullet. I dont believe there is any bullet that will be much tougher. I have shot partitions at 3400 fps with big cartridges and they do well from close range to out a bit. thats why it shocks me about the partition. anyways give 7828 a shot :) good luck

    Thanks for the load info, I'll post some pictures of the partitions I've had come apart. And the swift A- Frames. A-Frames are built with a heavier jacket and then bonded so they are a bit tougher. Partitions worked beautiful at longer ranges but the close range blow ups had me worried. Not sure what speed, 225gr. 98gr of RL25 was the load.

    I'd skip RL25 and go straight to RL26 to get the most out of your RUM with 250 grain bullets and below. The case fill % in the RUM case with a 225 grainer would be just about right and you'll probably safely end up around 3150 to 3200 fps.

    Wow, I see there is RL 23. RL 26, and RL 33 - 3 new mag powders since I last developed a load...

    Just talked to Steve, Ordered 50 of the 236gr. Hammer Hunters - he shoots these faster than I can and believes they will do what I need. He also reccomended the Reloder 26 also.

    I'd like to hear how it works for you.

    I've seen the petals come off the Partition, my recollection is it was designed that way.
    They will likely come off the Hammer as well.
    I've seen the Swift 275 A-Frame at work, and it does just that.
    Neither the Partitions or A-Frames, have been as consistently accurate as the Hammers.

    It may be that I always chamber a swift A frame when heading into the timber ;)

    Old habits die hard!:D

    I think the 236 Hammer is something I would not feel the need for a 2 bullet solution.
