1000+ yd. 30 Cal. bullet weights

[mfc1245]

If a shooter was capable enough to place a good shot on a deer at 1000+ yards with a 30 cal. bullet, what would the grain weight of the bullet have to be in order to adequately
penetrate and do its intended job? 165, 180 or 200...?
Thanks, very curious.

I use the heavest bullit my gun will shoot with the highes BC. If your gun will shot the 200g+ bullets that is what I would use.

Alot would depend on velocity ect...

I feel that if driven fast enough and as frail as the 155 AMAX is the 155 AMAX could be a contender. Otherwise something along the 200 Accubond would be my favoriate choice.

Thanks for the responses. I was hoping that the 180 gr. Barnes XBT out of a custom 26" Shilen barrell and Weatherby action with a muzzle velocity of 3250 fps might work? Or what about a 165 gr. Barnes XBT at 3450 fps muzzle velocity? I heard somewhere but can't remember where that any comparable bullet needed 1800 foot pounds to safely perform its objective; however I think that must be to high.
Thanks

Either of those bullets would be carrying about 1100 ft.lbs. of energy at 1000 yds. Just sufficient to kill 240 lb game if you can put the bullet in the right spot.

1800 ft.lb would be enough to take 450 lb game.

According to the Lyman's formula.

The 165 gr has a slightly flatter trajectory which would make scoring a hit slightly easier.

Seeing that you shooting at deer and the velocity your getting my vote goes to the 178gr Hornady A-max. Good weight with high BC will stay stabil out past 1K and the A-max tends to expand pretty quick so you get good expansion at the reduced velocity of 1000 yd impact.
Second vote goes to the 175gr Sierra MK

Thanks so much for the replies. Sounds like there is a lot of wisdom and intel out there in cyberspace. I especially like that Lyman formula, never heard of that before. Take care and good hunting.
