Re: 7MM Berger Conundrum

Not meaning to throw another wrinkle into the whole equation, but I had a question for Bryan on the 180 grain hybrid 7mm bullet. I was wondering how the 180 grain hybrid is able to have a higher BC than the 180 grain VLD? Does the hybrid bullet have a smaller meplat to go along with the hybrid design? Looking at the two bullets side by side the VLD bullet looks sleeker with the sharper secant ogive. Thanks.

Re: 7MM Berger Conundrum

Well after i got her sighted in at 100 yards, amazingly without using a holdoff (20MOA Base), I shot 2 2 shot groups (Dont like heating the barrel) and then my dad shot a 3 shot group. My best was just under 1/8moa at .114 Center to Center, my other group was .159 ctc. My father shot .993 ctc.

Attached is the target with information.



It is sideways and i wrote on the target upside down, but you get the idea.

These 180's can really shoot.

Re: 7MM Berger Conundrum

Forgot to mention it is a 7x300 Weatherby i shot this group with. A picture of the rifle is below. Traded my 338-378 wby accumark for this. The paint on it sucks, and it is missing an ejector (Or its just dirty, have not really examined it yet). There are a lot of things i am not happy with but once i get it cleaned up and fixed up im sure it will be great. Group was shot on a bench with harris bipod and rolled up Army ACU top as rear bag Sitting on top is a Vortex Crossfire 6-24x50 gen 1 (1" tube).

Re: 7MM Berger Conundrum

In regards to the difference in the two bullets as far as how they perform on game, I was told by the guy's at Gunwerks when they were smithing my 7LRM that the 180VLD performs better on bigger big game. I haven't shot a big game critter with the 180VLD yet, so I can't tell you whether it kills em' any deader than the 168's I've killed em' with.

Re: 7MM Berger Conundrum

Well the 180 has slightly higher Energies. But it is not enough to care about. I think that with what i have been learning they are identical to each other just depends on which one you can get to shoot in your gun. IMO there is not enough difference to even bring the point up, once you have played with things. If need be I can post Energy Vs Range tables and such. Also understand this is using a 7x300 wby at MAX (according to Load From a Disk) pressure.

Re: 7MM Berger Conundrum

great groups but i see you are pushing them at 2850 that is way short of the capabilities of the 7-300wby. when we used the 175 nos (1/2 in moa) back in 1993 we were pushing them to 3250 with 78.5grs of 7828 and h-870. i would think it would be reasonable to expect that out of the 180. i can get there with mine but the groups go to hell. over 3200 and the vld come apart because of the jump to the lands. we are going to try the hybrids to see if they will stay together. the bc is also better on the hybrids.
