A friend of mine that goes by "Bullet Bob" is coming out with a newly designed RBT- SLD .510" sniper round 715 grain. The Picture  Enjoy!! Oh yeah and his website: www.customprojectile.com/prodserv.htm |
Honestly, you think a Holow Point is really going to kill much better then the bullet that Canadian sniper used? He seemed to do well out to 2400 yards.

Well, yes and no on the HP deal. First and foremost, the main reason for the HP on those designs is due to the manufacturing process. The jacket is formed, THEN the lead is put in somewhere. So for a FMJ, the lead is filled through the back, leaving that area open. For match bullets, it's the opposite, and. However, there is a few things to remember. A match bullet, although considered a HP, is in actuality, an "open tip" design. A true hollow point has a hollowed area in the core. For instance, look at a pistol HP to get an idea what i'm talking about. If you look at a cutaway of match bullets, they don't have this "hollowed" area in the lead. So a true HP IS designed for expansion as air will be violently forced into the core causing rapid expansion. For a match bullet "Hollow point", I'm trying to remember, but I'm wanting to say that moving the center of mass back (by leaving the tip empty of heavy lead) causes the bullet to be more stable, which probably means it will stay "asleep" longer and at lower speeds before it starts to tumble. As for simply not having a tip, a quick look at Hornady A-max's makes me wonder if the lack of a tip is simply a cost issues, and also the possibility a tip will induce more inconsistancies than just leaving it open. Now, given many .50 projo's are milled from solid alloy, or done out of copper, "filling" a jacket is not a necessity, so a HP design would purely be a functional addition of some type. Anyway, just thought I'd share what I seem to remember about the subject. Gundraw |
I'm not real familiar with these. So are you saying in addition to having a open tip, it has a hollowed core "V" inside? I really wouldn't think that would shift weight enough to be worth it! However, you very well could be right. I'm just giving information i found to be true and make sense. Gundraw |

From my friend. 100 count lots for a RBT-SLD 715 Grain . 5105" @ $1.46 per piece and $8.50 S&H&Ins so $154.50 shipped to there door. it will be about 2-4 weeks before production begins but we started excepting orders and all are being told about a month before delivery will begin.... later today i should be able to give out the specs on the new bullet design for those that want to run there ballistic program numbers. none of this is up on our site yet been to busy but people can call and pre-place there orders we except master card and visa. |
One thing for sure judging by the price he has a high opinion of his product (maybe deservingly so). He's pricing this product in Barnes/Hornady territory. It's also a pretty bold statement to be taking orders for a pre-production component with no proven track record in either the products performance or in the company's ability to deliver this product. Sounds like he's collecting the money to fund this project. I would definitely have to wait and get some feed back before making a purchase here. |
The point was that the HP bullets move the center of gravity to the rear give much better stabilization. We shot a bunch of it when I worked at Barrett. The rounds were made for us by Winchester. They shot fantastic well past 1500m. |

Tony, To bad Winchester didn't win the contract to supply the military, HSM is selling the leftovers. The French ended up winning the contract with their Anthena designed bullet. The presence of the open tip is to make the bullet longer without adding too much weight and shifting the center of gravity too far forward, it's not for expansion purposes. Being solid brass, I doubt it would expand. Hornady used a different approach by making the bullet longer by using aluminum. |
Thanks for the info, I learn something new here every day
