.270 or .308

If a .308 had a 1:12 twist rate would it be a suitable rifle to shoot bullets up to 200 grain?



Not particularly no. That is a bit slow for anything above 130 grain really. For .308 I have found a 1:10 to be about perfect for my load selections. And I vary from 130gr SP to 180gr Interbonds out of that barrel (TC pro hunter)
 
How is this a duplicate post?

mine was a duplicate post.... hence the reason I was asking a moderator to delete my duplicate posting (I edited it to put in the please delete). the duplicate post happened because I hit the post button and then accidentaly reloaded the page and thought I lost what I typed and retyped it and then saw both posts :banghead:


anyway carry on. sounds like you ahve your heart set on a .270 so get one and have fun.
 
Ok, and no not entirely I like the concept of utilizing a 200 grain bullet and down to 150 or lower with an -06 but the flatter shooting capabilitys of tge .270 are appealing
I feel like a kid in a candy shop with only a quarter!!
 
1 in 10 is the norm for 30/06 and is good to go up past the 220gr mark, but then you run into OAL issues with the magazine on the gun for bullets bigger than 220gr. Also the 1 in 10 in a 30/06 chambering will launch the lighter bullets with ease and accuracy as well.


If you are still considering a 308 here is the information from shilen (the barrel maker) on what they recommend in 308


- 8" for bullets heavier than 220gr.
- 10" for bullets up to 220gr.
- 12" for bullets up to 170gr.
- 14"* for bullets up to 168gr.
- 15"* for bullets up to 150gr.
 
Just to clear somthing up, a 1:12 twist 308 will stabalize up to and including a 185gr boat tail spritzer bullet. This comes streight from Burger Bullets and they know a thing or two about accuracy to say the least. I did a very detailed camparison of the 308 the 270 and a dozon other round in my "Head to Head: Practical Big Game Rifles" thread in the rifle section. The 308 scored much higher when elk sized game enter the picture. The 280 Remington also scored noticably higher then the 270, they both launched heavier higher BC bullets then the 270 did and that made all the difference. Even with the 270s lack luster performance it did score good on the trajectory test, and held a 468lbs Optimal Game Weight at 300 yards, so I don't think deer sized game would live long enough to complain about it :)
 
Sighted in for two inches high at 100 yards, the .270, the .308 and the '06 will all be close to dead-on at 200. Drop at 300 will be around five inches or so for the .270, maybe, and around six inches for the .308 and '06.

Not enough difference to ever notice in the field.

I finally got back into centerfire rifles in 1963 with a .270, and then in 1970 I drifted back to '06-land. I figure I have a wee tad of experience with those, plus a fair amount of observation of .308s at my range at my house...
 
as for the argument of bolt or semi its a no brainer i will be buying a bolt for the simple fact that i have never needed more than one shot.
Good luck on your moose hunt!

i have though long and hard about the .300 win mag and come to the conclusin that i would like to stay closer to something between a .270 and a .30-06 for the simple fact of shooting comfort after a day at the range i would like to be able to do something other than sit with an ice pack on my shoulder this is also why im straying from the -06, and leaning towards the .270 or .308. but i have shot both the .303brit and .30-06 and found the recoil to be managable but i belive that a .308 or .270 would be better.

Here's some interesting comparisons:

.308! bigger piece of lead and less recoil. follow up shots will be easier. 270 is a great flat shooting round......but you want a 'do it all' bullet, which is the .308
 
308 is my thoughts, quite a bit of brass around for reloading and it has a much wider range of bullets to shoot as in weight from the 110 area to over 200 grain... best twist is the one your rifle has :D work up a load by practice;)

I have both 270 in 1:10 twist and 308 in 1:12, as far as 308 and 1:12 twist I had good results from bullets in 150 gr - 175 gr range, actually I found 175 gr group better on 500 yards, it could have been affect of higher B.C in 175 gr SMK vs 155 gr SMK.. with 270 the heaviest I shot are 150 gr Nosler's ballistic tips great B.C and great results on paper...

There's nothing a 308 or 30-06 can do that a 270 cannot, and vice versa; all three have killed a LOT of game animals.

Personally, I'm rationalizing my collection and getting out of the 270 business...but only because I already have a 30-06 (and more components for it) and my 270 has been a PITA to work a good load up for.

I'd take the 260 Remington before all the above...pretty sure whitetail don't care about NATO standard and besides, that's what reloading components and the AR in the safe is for.

This is like which is better , a Ford or chevy. Both are really good cal`s with proven track records. Reading the various posts indicates honest opinions on both sides.
For me, I`ll go the .270 route. Reason, I just don`t like the .308. Nothing else, just don`t like the round. Besides I`ve got an 06. :)
 
The 06 is just more powerful especaly if you like heavier bullets, the 308 is crazy efficient, low recoil, very little powder burnt, all while staying relitivly close to the 06's performance. The question is do you NEED more power because the old 30-06 will sure give it to you. I consider the 30 cals to be superior to the .270 cal because the standard twist will stabalize much heavier higher BC bullets. That said I do LOVE my 270 WSM for blasting deer all the way across the penut field, it shoots stupid flat and carries more energy then I ever need for deer.
 
But what I really like for these Texas white-tails is my 257 Roberts with a 117 gr bullet.
 
for me, since I have both calibers I see no difference, this season I was switching between both on the field, as far as white tails, they wouldn't know a difference what hit them... both calibers carry enough energy to be used up to 600 yards, and can be used to punch paper at 1K...
