Thinking might need to try in my 300 Norma Imp I'm in the middle of building. Just not looking like they would fit well in my AICS mag setup.

If it is a CIP length you should be good.....if not, they didn't seem to mind a jump in the guns I have tried them in....

Do all the new versions utilize the "Death Star" hollow point? From 22 caliber and up? Also what percent of the weight loss is petals? 40-50% with the rest being the shank? I'm interested in the 110 gr 0.257 And 100 gr 6mm. If the BC is right that100 gr out does a 115 Berger. I think the 100 gr out of my 6 dasher hunting gun would be a good match.

The 6mm and under bullets do not utilize the death star. They have a smaller hollow cavity, and still use a 6 point broach. Actually the reason for going to the death star in the larger bullets was to get them to perform as well as the small bullets did. The broaching in the .224 and .243 bullets is just the right size in relation to the hole size, and the small bullets always performed incredibly. But a broach just the right size for the bigger cavity was t available. So we went to our broach manufacturer, and had custom broached made to match our hole size. Now all the new bullets should perform as well as the small bullets.

Thanks for the explanation. As long as they shed the nose/petals. I prefer that to the Barnes. Haven't got a definite answer as to weight retention. What percentage of the weight is petals?

They're not necessarily designed to shed petals. At high impact velocities they shed about half the petal. You can see at 2793fps it shed the front half of 4 or the 5 petals. At 2473 it retained them, and though it doesn't look spectacular, at 1689 that bullet is still expanded to 1.5 calibers.

 

[Trigger24]

The exact percentage of weight in the petals will vary slightly from one weight of bullet or one caliber to the next. But expect 85% retention minimum.

What speed are you getting out of your RUM with the 205? I have been following this thread and wanted to try some for my RUM, Creed, and a 6.5x284 I'm currently putting together. TIA

A 205 at 3300 with N570 out of my 300 NMI sounds pretty fun. But probably would make my barrel wear out pretty quick...

 

[BEEMAN]

Thanks for the pictures trigger24. Guess I'll have to order some and try them. Only problem is here in Manitoba we can only shoot one deer. Maybe the border will open up for this year and I can go stateside and test where I can shoot multiple deer.

Does anyone have experience with these bullets and Quick Load? I just ordered some 275 grain Super Bulldozer-2's for my .338 Lapua and some 135 gr Super Bulldozer-2's for the .264 Win Mag and maybe 6.5 creed. Components are tight, I'm down to my last pound of H-1000 and 869, and I have a couple of pounds of Retumbo. I really don't want to burn up a lot of powder for load development and hope to use QL to get close enough, however there just aren't any name brand bullets like these in the QL drop down.

Quick load data won't be much use for these bullets, they pressure up earlier.

This isn't the same, but here is my load work up in a 24" .338 Norma mag with the 270 SBD, which has 2 pressure relief grooves, not just one.

Peterson brass
GM215M
270 Badlands Super Bulldozer
Seated .025" off, 3.819" OAL

H1000:
87.0 - 2782
88.0 - 2801
89.0 - 2846, beginning pressure signs on primer, discontinued work up

Retumbo:
88.0 - 2803
89.0 - 2823
90.0 - 2858, beginning pressure signs on primer, but didn't notice it in the dark shoot house.
91.0 - 2906, very light bolt lift, discontinued work up

This is what quickload says with your data, but substituting a Barnes bullet, modified with the weight and length of the 270SBD. I could probably play with the weighting factor to match your data exactly, but it's good to know I should start 10% low. Thanks for the data, it is useful.
