Rod, Thanks for the first hand experience regarding the BFR 45-70. I kinda was thinking along the lines of a compact, smokeless version of the old 50-70 Government. Maybe I should look into the 45-70 option again. I was kinda hoping for a bit more diameter is all. Still a worthy consideration, though :o)

I figured there must be some tumbling involved that makes the Whispers effective. Just figured that the larger calibers would take several inches to upset. I'm showing my ignorance, I know :o) I'm researching them right now, though. Thanks Again for the input :o)

I was really drawn to the cast option due to cost of reloading. I'd really like to put a couple thousand rounds per year downrange at various distances. Perhaps there are cast options available for the Whispers as well? Back to my hole I go for more research ;o)

BFR is also available in .500 S&W if you want bigger than .45 cal. Keep in mind that the twist rate may not be fast enough to stabilize the heavy bullets you are considering at sub sonic muzzle velocities. So you might have to replace the barrel on the BFR.

Yep, I'm bugging the BPCR shooters also regarding the bullet stability at longer ranges. The rifles they use are very similar with regard to caliber, bullet weight, etc. However, I believe the twist rates for their rifles are much slower than those of the BFR revolvers. Thanks for the input :o)

I'd only be thumping paper at 400 yards ;o) I have a personal rule that I practice at twice the distance of any shots taken in the field. With practice and depending on what the platform is capable of, I might move out from there. I was planning on a 4X optic because of the balance between field of view and magnification. In theory, that should be enough for broadside shots on big game out to 300 yards or so. I'm leaning conservative on this, as up till now I've been devoted to the open sights :o) It still amazes me how precise they can be :o)

When I ran the numbers before, I came up with approximately + or -2 feet out to 275 yards if zeroed at around 230 yards. I've used this type of zero in the past and got comfortable estimating hold. A range finder will definitely be employed every time :o) 1100 fps shoots really flat compared to the long bow, airguns and low velocity powder burners ;o) The 270 win got boring after the first couple trips ;o)
Still great points for me to consider. Thanks for the help :o)

As I said too if you'd rather have a true .510 caliber the BFR will handle the 50-70 but it means a new barrel and rechambering the cylinder. I know at least one of the guys on here mentioned having a BFR in 50-70 and I think there are a couple 50AK's which may be more than your looking for in the recoil dept. The 45-70 will most likely give you more what your looking for in trajectory.

The .500 Whisper (SSK) was developed for certain government agencies and has worked very well at extended ranges. I've taken several deer with .50 cal. AMaxes out to 200. It has been used much farther than that in combat. The problem with the .500 is the expense-special made cases, pricey bullets, and expensive gun.
The .375 Whisper is not working well due to poor bullets available. I know of no .475 bullets for extended range work.
The .338 Whisper is O.K., but the gold standard is the .300 Whisper-reasonable prices for bullets, brass, and gun. Performance? I've done deer to 270 yards. I know of much larger animals taken with it. With the right setting on a mildot scope farther ranges should work, too.

Been reading the "300 Whisper for Deer" thread on this forum. Seems to be a possibility worthy of consideration :o) Big question for me is, "How does it fare against larger game?" i.e Full Grown Roosevelt Elk, Moose, Large Bears, with broadside chest shots. Also, how is the performance when encountering heavy bone? Interested in info for velocities around 1050 fps at ranges between 50 and 300 yards.
Thanks Again to all those who have taken the time to share :o)
