Home Forums Reloading Varmint Rifles twist for 6mm

I'm kinda thinking that too - even at 6-284 vels.

I'd punt

That sounds like something I could believe. I mostly shoot Sierras at targets anymore. But that Sierra bullet is long enough to indicate the 244 can shoot bullets designed for deer.

I have only shot M60, M37, M14 and M16's at sealevel or close to sea level. So I have no experience with testing different twists etc at sealevel.

I don't suppose that you would provide the name of the program. I'm not against using a good program, but what I've seen not so much.

What length of bullet does your program say the 6mm with a 14" twist at say 3400 ft per sec. If you're saying the longest bullet is a 58 grain Hornady, then I concede.

The 243 WSSM should be abel to push a 80 grain bullet to 3600 fps, I suppose. I don't think that there's any appropriate bullet for deer shorter than most 80 grain bullets.

The NPT 85 grain @ 5000 ft. 59 degrees, 3400 FPS has a stability factor of 1.1, @ 32 Degrees its 1.02 in other words its marginal at best as 1.5 is considered stable. Minimum suggested twist is 1 in 11.5 per Berger. Sierra says 1 in 12.5

Looks like 80 grains and length of .810 is your huckleberry. NBT Varmint

This barrel belongs on somebody else's rifle. It is now officially for sale!!

Well maybe someone who hunts where deer are antelope sized could use it and a Hornady 75 grain HP....

seems like some old timers around here, like those 75 grain HPs for blacktails...and start their grandkids out on them....

Well, just look at the .223, .223AI deer hunters and how they brag on their choice. Makes the 75 gr. 6mm look like a "big gun". I'd for sure select well constructed bullets, staying away from explosive, varmint type projectiles.

Just saying...

What?

I owe Steelhead an appology for my reply. Sorry Ace.

People say I often use guns that over-kill. I suppose I do, but when I look at the deer/antelope/elk lying on the ground I can't see any evidence of over kill. What does it look like?

I know what it looks like with prairie dogs however.

Yeah...

I don't think Bugger was implying that you were an ole Fart or something, using a kids gun to shoot deer...

DF

Ain't no trick killing if you can shoot. If you can't shoot, then what you use don't matter much.

For some odd reason the concept of putting a good bullet where it belongs escapes many.

Big hole, lots of daylight...

Not meaning to imply anything about someone else. We all have had experiences that lead us to some kind of opinion. A person's opinion is nothing to making fun of. They came by it through experience, hopefully.
Personally, I just don't use the smallest lightest caliber that will kill or I'd be using a 22LR, perhaps a 22 Hornet.
I have used a 300 Win Mag on deer, but only once. I was expecting possibililties of very long shots. It turns out I shot both deer on that trip at under 100 yards and a 30-30 would have been totally sufficient. The 300 evidently over-killed, I guess. My preference for Western deer hunting is a 280 with 154 grain bullets or a 30-06 with 180 grain bullets. But there's nothing wrong with many other calibers/cartridges. I could be as happy with my 7x57, but the stock is too pretty to be dragging through brush. I have used 6 mm on antelopes and am confident it would also work on deer -- I would be using a well crafted bullet in 6mm designed for penetration and expansion. In my experience 75 grain HP's not be one I'd likely use.

Besides I'm an old fart. Calling someone else an old fart would not be an insult.

One ole fart messing with another ole fart...

Just had to take a poke at Steelhead...

Couldn't help myself...

You're golden if hunting vampire deer.

Wouldn't one need a wooden stake for that kinda work...??

Daylight kills vamps, not deer.

In a 6mmBR built with a 14" twist 6mmPPC take off barrel, I can get 65 gr Vmax to always stabilize, and only sometimes the 75 gr Vmax.

This being a bull and fluted probably not ideal for a youngster to learn on. This is a "target" barrel, I just don't shoot in competition. My 243 Encore has a 10" twist (I think) and with 100gr Sierra GameKings, kills antelope before they hit the ground. I was hoping something like that bullet would work in this barrel - but NOT!!
I don't have a 700 action laying around to pair this with, so it goes in my "barrels for sale" category.
Should be a really nice barrel in competition - I think there is a rifle sport for 300yds or so ?

I shot a 244 AI with a 1-14 twist and it stabilized the 80g Sierra Blitz just fine at 3700+ fps.

Winchester makes an 80g sp that is a dandy deer bullet out of a 243.
