I was wondering 416 WSM, 416 Ruger, and 416 Taylor or an Ackley Improved version of these rifle cartridges VS 416 Remington, 416 Rigby, or 416 Weatherby ballistically speaking. Thanks
 
You have a very broad range of case capacities in those cartridges.

There are some high BC bullets available but most of these are setup for dangerous game type bullets.

The 416/300 WSM would struggle to push 350 grainers to 2450fps in a normal length barrel. The 416 Weatherby would push that same 350 to more like 2900fps.

Even the "slouch" of the bunch the WSM should be capable of 4500lb energy at the muzzle. Nothing to sneeze at. The Weatherby is closer to 6500lb. That would get your attention.

After that if you are interested in drift and drop. Need more info on specific bullets preferred and barrel lengths.
 
Well as far as bullet type I was going to go with the high BC Cutting Edge, Barnes, or other high BC copper or brass bullets. As far as barrel length which I think will have the worst deregration on the cartridges I selected to compare will be SHORT 16.5" to 20" I do realize that this will slow velocities down quite a bit because most velocity tests were done with a 24" or 26" barrel length if someone cuts the barrel back by 9.5" to 6" even if you only lose 25 FPS per inch will be a 237.5 FPS to 150 FPS loss but if it's 50 FPS loss per inch it will be 475 FPS 300 FPS I could Ackley Improve the cartridge but the gain will probably be minimal considering. Thanks
 
OK, so I got a little more criteria to base an analysis on.

I love doing this kind of thing....

Bullets that I think meet the high BC:
Barnes TTSX 350
Cutting Edge: MTH_V13 375
Hornady match 450
Barrel length:
26 inch. You can adjust from there. 25fps per inch for close enough.
Cartridges:
This will give a range of powder capacities from ~80 to ~120 grains.

There are many many options I could include such as a 416-Taylor, 416 Ruger, 416/26-Nosler, 416 Dakota, 416/338 RUM or 416/300 RUM, 416/300 Wby, 416/7mm STW

but

That would take forever.

I am going to use the CEB seating depth for all the loads because I think that is the most "fair". Of course adjustments in seating depth will have a large impact velocity.

Output data:
Velocity at 56k PSI
Energy at the muzzle
1000 yard drop from a 300 yard zero pulled from JBM

Does that work for you?
 
Thanks jfseaman sounds good to me (you're just going to add the 416/26- Nosler, 416 Dakota, 416/338 RUM, 416/300 RUM, 416/300 WBY , and the 416/7mm STW to my list right?) . I was planning on using a Howa 1500 / Weatherby Vanguard Action with a custom barrel (possibly a Pacnor ) and custom rifle stock.

Thanks jfseaman sounds good to me (you're just going to add the 416/26- Nosler, 416 Dakota, 416/338 RUM, 416/300 RUM, 416/300 WBY , and the 416/7mm STW to my list right?) . I was planning on using a Howa 1500 / Weatherby Vanguard Action with a custom barrel (possibly a Pacnor ) and custom rifle stock.
3 bullets, 3 cartridges = 9 combinations 2 hours of work.

That should give you an idea of how to narrow down what you are trying to accomplish.

Come up with something specific and I will work on it.
 
Thanks jfseaman it's probably just my thinking but I would think that the heavier/heaviest weight bullets compatible with the rifle cartridges compared would work best especially if I'm going to shorten the barrel. Think about the bullets commonly used in subsonic cartridges heavy bullets with the higher BC because once a bullet achieves its maximum velocity it takes longer for it slow down (example train vs sports car) the high BC helps this too.

Come up with something specific and I will work on it.


Hear is the 416 buffalo that I came up with that pushes a 400 grain bullet right at 2700 ft/sec without excessive pressure. (It will go higher but I wanted it to be very dependable and not heat sensitive) as far as I know it is second only to the 416 Weatherby.

I felt it needed a 26" barrel but it would handle a 24" if you wanted it shorter.
