Long Range Build - 7PRC, 7BC, 300PRC?

[nm.otter]

all of these are effectively lethal 1400+ yards

Sounds about right.

if I can put the bullet in the right spot.

...which you are far more likely to consistently achieve when shooting a lighter-recoiling load.

That would mean all of these are effectively lethal 1400+ yards on elk if I can put the bullet in the right spot.

I honestly don’t know what the specifics are of those bullets and don’t care to look. Mono metal = 2200fps, bonded at least 2000fps, some match type 1800fps.

Why isn’t a 28 nosler on this list?!

 

[Woodsman44]

At 20-22” barrel isn’t it about the same as a 7BC?

ADG sells brass for 7/300prc. So you can have 300prc case capacity and 7mm bullets

 

[Quandary]

My most accurate loads that I hunt with in my 7PRC and 300PRC are the 175gr Elite Hunter and the 200gr CEB Lazer respectively. Both 22" barrels. the muzzle velocity, at 850 ft, with the 7 is 2,858, the 300 is 2,875. If I adjust that to 8,000 ft I am at 1,919 for the 7 and 1,817 for the 300. Either on will do the job but unless you find a higher velocity node 1,000 is about the distance envelope for both.

6 UM bang flops elk at 905 from lung hit with 243 recoil
Current load and velocity keeps 1800 fps out to about 1200. Though there's been some things killed with dtacs well below that. But frick, that's way too far for most people. Myself included.

Well crap! I just dug through the 100+ page 6UM thread. Looks like that’s a 1200+ setup. What are the benefits of going with a 7BC over 6UM for long range elk? Wind?

Kinda like having small hands . Elk killed w 6UM look bigger.

 

[Woodsman44]

Serious question though. Off the top of my head, 6UM benefits are reduced recoil to the point of spotting hits and potentially more precise because of reduced recoil. Benefits of 7BC are more killing capable on shots that miss the mark a little, better bullet selection (1 bullet for deer and elk vs dtac plus barnes MB), better chances of animals dropping quicker and in sight, reduced wind impact?

This isn’t a “thing.” The extra millimeter of diameter makes no measurable difference assuming equal bullet capabilities.

 

[Woodsman44]

Even pushing 60 more grains of bullet?

That would be a 28 Sherman Mag if you fire form for it. Slightly less capacity but better brass options than the Nosler

With the right projectiles, it's quite likely a 7mm will cause more damage than most of us would prefer to see.

Thread 'Compilation of Formidilosus posts'

Hopefully this doesn't step on any toes. I've found Form’s posts to be incredibly useful and have spent more time than I care to admit digging through his posts. Attached are a few of the "core" posts I have saved for reference and to share with friends. To be clear, this is all Form’s content, some is older work and views may have progressed

@Formidilosus Thank you! If you have put all this in a book/website/ program let me know and I'll buy it. If not, you have a heck of a start, sign me up when you do. If the post violates decorum, please let me know and I'll happily delete...

Under post # 5 I have linked the “Why Match bullets for hunting thread”, regardless of if you want to use match bullets the thread goes into different bullet types and the wounds they make.

There's no need for multiple bullets for the 6 UM. The DTAC kills thin skinned game just fine. The new 115-117 TMK solves that even more ideally.
The only realistic advantage to the 7 BC might be barrel life. The UM will kill in the field as well or better. Anything that's an actual step up in performance beyond 1k is going to be burning 100+ grains of powder and not fun to walk around with.
