7ultra, I just don't think at the velocity you are talking about you will get the bullet expansion and energy to take deer. I think what Ric was saying which I will as responible hunter we should not use bullets that cannot reliably kill a game animal.

Re: Question for Extreme LR 338 hunters

7ultra, there are no jacketed bullets that will work on game at those velocities. Same effect as shooting FMJ's at them. Good or bad is up to you.

You can consider cast with a FN or Keith type profile or better yet go with a large bore (40 or 45cal).

Utimately, this combo (338 Whisper) would be lethal but certainly not effective in my books.

Re: Question for Extreme LR 338 hunters

Thank you guys for the response,
I'm sorry if I sounded pissy, just trying to re route this thread. The 300 grain match king was just an example. The 338 whisper was designed to be an easily suppressible round, while having the ability to go a little bit faster. The reason I asked the question about bullet performance, is because I know there are members on this board who hunt at these ranges, and with success. The rifle itself will most likely easily attain 1/2MOA or less at 100 yards, so know I just need to know about bullet selection. Thanks

Re: Question for Extreme LR 338 hunters

heavy bullet in 338 cal are design to expand at high velovity

338 Wisper or any small case doesn t deliver enought velocity to get a proper expansion so you get a close FMJ effect

that the opposite in 35 cal where bullets are design for low velocity ( 35 REm and 358 win ) so when you push them fast you get quick / too fast expansion ( 358 STA or same class of magnum )

good shooting

Re: Question for Extreme LR 338 hunters


I agree with the on game performance problems associated with using the 300 gr Mk at these low velocities. The bullet simply would not expand at all, not even at near muzzle velocity you are talking about.

I am not saying your idea is a bad one, in fact, I think it could be a very useful hunting tool and extremely accurate to boot.

Just swtich to a 180 gr Ballistic Tip for game hunting. You could get into the 2600 fps level if you wanted pretty easily or load down to 2400-2500 fps with no more recoil then the much slower 300 gr MK and over 200 yards the ligher 180 gr BT will shoot much flatter adn expand very reliably on game.

The 300 Whisper, your ideas little brother, has been used a great deal as a big game round, espeically out of handguns which is one of my main passions.

In the 300, the guys I know switch from the big 220 and 240 gr Mk that they use for target shooting and use a 125 or 150 gr Ballistic Tip for deer. Recoil is the same, trajectory over moderate hunting ranges is actually flatter with the light bullets and they expand reliably down to 1500 fps or so in both the 308 and 338 familys of B. Tips.

Just an idea, would add better on game performance to your interesting idea and the B. Tips in 338 are flat out match accurate in my XP-100 15" handgun chambeed for the 338 WSM.

I have taken +300 lb mule deer bucks at 320 yards with the 180 gr ballistic Tip driven to 2800 fps at the muzzle. this is quite a bit over what you would get but bullet performance at that range was perfect with full expansion and penetration.

Good Shooting!!

Re: Question for Extreme LR 338 hunters

Fifty, once again you took the post right off of my computer screen. My intitial logic with even considering the 300gr Mk for hunting was that I would be able to take an accurate round on paper and use it in the field. Of course I had concers over bullet performance, hence the post.

Thinking about it more, for hunting situations, the lighter bullets would definately be the ticket. You think I would be able to get that kind of velocity with the 180's. If thats the case,it pretty much locks the Whisper as my cartridge.

Now, in your opinion, what should I do for a barrel. The twist would be 1-10(right?). For barrel contour, I want something pretty thick, like maybe lilja's heavy varmint contour(straight taper). Now what about length. I said 17", mainly because legal length is 16 and 1/2 and this cartridge wasn't meant for too long of a tube. Any advice or experience would be great.

Re: Question for Extreme LR 338 hunters

7 Ultra---- I would check this out before going to a 338 whisper. The 50 Whisper leaves a .510 hole in whatever it hits, you won't have to worry about bullet performance. I ordered one last week with an 18 inch barrel. It is set up on a 338 Lapua case. [img]images/icons/cool.gif[/img]
