Berger 300 Hybrid - 3rd Shot -OH! MY!! GOSH!!!

[bigngreen]

Way to sacrifice your rig to the power of the Berger!! I have a feeling no elk will deny that bullet, it may breath some more life into the slower end of the 338 chamberings, I may have to see if the local barrel guys have any 338 stuff laying around when I pick up my 270 barrel 300 grain elk bombs by Berger

Roy, do you think it's just the Berger design that's causing those results (looks like a bomb went off) or is it possible a similar weight/design bullet would yield the same bomb affect?

I think it may well be a decent idea to head to Jeff's with the (new) fixture and media and move the test waaaay out there. I'm having a rough time finding the distance.

Oh BTW all three of these cold bore shots have centered on the 300 yd zero POA in a group that is scary small.

Wow! 23 inches! I tried to dig one up from my 1500 yard group. I quit at 12 to 15" thinking it must have bounced up. I bet is was deeper as it was a sandy clay soil.

" Scary Small " Good discription! That is exactly how I felt after some of my first groups with them. Scared that they were flukes and woul not repeat. But they have kept it up. I am shooting better, I shoot Bergers!

Roy, you are welcome to come by any time. I do have a place or two to shoot, at least to a mile or two anyway. I have been looking for something to test with at 1000yds my self. I mentioned the possibility of a freezer burned bone in ham wrapped with a water soaked deer hide. But when I stuck my head in the freezer to dig, I was run off with a broom..

Good job! Your efforts are appreciated.

Where am I going to get a "similar weight/design" bullet. I think the 338 Hybrid is in its own class. Comparing with an SMK would be a bit like testing a apple against an orange.

Disclaimer: this paragraph contains my own opinion(s).

Both the 300 SMK and 300 Hybrid have the same beginnings. Both were designed as a "match" bullet. The effectiveness of the SMK for hunting was serendipitous. The Hybrid was designed to achieve a very high bc (success) accurate (success) and maintain the "Berger" terminal performance (success). The Berger 300 Hybrid will find its niche very quickly.



Regarding the "bomb affect" I think the shear mass of a 338 - 300 gr bullet is a rung or two above sub-caliber offerings (.308 and below). When I loaded down a 300 SMK to achieve 1k velocity at the muzzle and tested it on my wooden fixture creation the first experiment blew the fixture apart resulting a major redesign while it handled the 270 170gr quite well.

Using a MV of 2700 FPS calculate the foot-pounds @ 300 yds and dissipate that energy in 21 inches w/o hitting bone and 15.5 inches penetrating bone first. The empirical experience says somethings gotta give.

As much as I like to blow thing up this deal isn't enjoyable.

I'll redesign (have some great ideas) and do another 300 yd test with both Hybrids and SMKs. Hopefully this will result in a bullet test instead of a bullet performance AND fixture test.

I'd like to see the high speed video of the Hybrid shot into that jello stuff with jello stuff fully contained instead of free standing. Either way I bet it better be done outdoors. As in Antlers on the ceiling! Who goosed the Moose.

This reminds me of last fall watching through my scope as a 180 gr bullet from a 300 WBY found its home, sent from 360 yards, right behind the shoulder of bull elk. I can still in my mind see the shock waves of rumpled hide move out from the POI. I gave the shooter a thumbs up, but he was worried as the elk moved forward in the slow death walk. 25 yards later he crumpled and never even kicked. I think trying to contain this type of shock could prove to be tough. Might I suggest posibly an truck ot tractor innertube filled with your media?

Wow Roy! You're a pipe killing son of a gun!! That is impressive if not down right scary. I can't believe how it detonated that pipe. Very nice. I think you found your new elk round. Question is. Will there be any elk left when you go to retrieve it?

Thanks for responding Roy, correct me if I'm reading too much into what you said but, it sounds like the bomb affect wouldn't be limited to just the Berger but there might be similar bomb affects with 300 gr smk?
