.270 vs .308 ?

I like my long action t3, the hair on my knuckles protects them from the bolt and my neanderthal shoulders help me cope with the recoil.

Surprised no one has suggested 30-06 for the long action rifle. :stirthepot2:

Going to try and beat the thread in one post, and I'll fail, but I'll try:

-If you're inside 250 yards, doesn't matter.
-If you're beyond 250, or the possibility is likely, .270 all the way.
-If you want cheap FMJ for plinking, .308.
-If you live in Southern Ontario, .270.
-If you want bang flops, .270 has the edge.
-If you want to shoot a Bison with the smallest possible cartridge, either fits equally.
-If you shoot semis, then .308, as it is available in many good ones.
-If you want to shoot a T3, .270. But better yet sell the T3 and get a Winchester in .270.

I never really buy this argument.

Learn your drop data, learn your holds, learn your windage calls and holds, and learn em very well. It's all part of ANY caliber and rifle.

Or, sight in a .270 shooting a 110gr TTSX at 300 yards, and you will hit within a radius of 3.5" from zero out to 350 yards. Visualised, place two playing cards end to end and put your finger on the seam, that's the entire extent of its rise and fall either side of your finger right to 350 yards, with no elevation compensation required in aim. All from a very "boring" and normal off the shelf cartridge, even the load is available from Federal off the shelf. Admittedly this stuff is a lot more important in the mountains than in the bush.

Agreed, just mean for the caliber restriction non-sense. ;)

Not trying to disrupt your argument, as I am a 270 fan myself as I already stated, but your analogy is slightly flawed. Yes the bullet drop for a 270 with a 110 gr bullet is very minimal so holdover is minimal or "point blank range" is extended. But also keep in mind that a 1 moa gun will shoot a 3.5" group at 350 yds so with a 3.5" group centered around a 3.5" drop you could have up to 5.25" of drop for any particular shot with a 1 moa rifle, and this will only expand with anything less than that,

Now you're talkin' :cool:

They are both very good. I prefer the 270 myself but have nothing bad to say about 308. Once you are familiar with either one, you will be able to shoot as well as the other. Once you have the feel of a caliber everything falls into place. The same applies to a lot of calibers. It all depends on how big of a hole and how much of a smack you want to put on the target.

Yep, and sounds like you've shot your share of groups too, and therefore know most land towards the center of the dispersion. Secondly, maximum point blank range is pretty typically defined as +/-5", well within the bounds. Finally, the analogy isn't flawed in my eyes, as gravity is constant- whatever the dispersion caused by the rifle and shooter, your bullet is still humming along its +/-3.5" trajectory to 350. The rest is up to the ahooter to determine if the rifle can take advantage of that. The .270 performs as advertised, the rest of the gear and shooter is a question mark, so I note your point.
 
I was out doing load testing today. the 150 gr Matrix bullets were being pushed out of my 270 win at a little over 3K fps a pop... In a gusting wind, some of the groups were under 3" at 230 yards... Gun doesn't seem to like crimped necks seated at the lands...

Based on that trajectory, it would stay within 5" rise and fall from line of sight with a 300 yard zero to approximately 350 yards...
 
.308 win for BC - because up close and personal with a big animal that can hurt you, the heavier bullet and the bigger cross section (23% bigger) gives you more confidence...there is a even a 220 gr 308 win factory load from Hornady...

I love also that 308 win is a shorter and more effective cartridge (than the overbore 270 win) and you can have it in a much smaller and lighter rifle with short action and shorter barrel...

Ardent have you been possessed by Jack O'Connor?

What happened to your 7x57 double?
Click to expand...

Have never owned a 7x57 double, doubles are medium bore and better in my eyes. ;) I do have a lovely single 7x57, and the 7x57 is swell but outperformed by the .270 (which is outperformed by the .270 WSM, which is outperformed by the 7mm STW, and so forth :) ).

I believe the .270 is where my buck stops in that race, it's fast enough (favourite load right now is a 110gr TTSX at 3400fps), and you are right I am having a bit of a love affair with it lately.. It's been the sleeper in my cabinet a long time, under appreciated. It's boring and it bloody well works: Since 1923. I'll be bored of it again by next season perhaps.
 
I must be thinking of someone else, maybe even someone I have met in person (fancy that!) who owns a 7x57r o/u.

I am dead set on adding something that starts with 7 to my cabinet for deer. Bullets below 140 grains make me break out in hives for some reason.

I do the same thing with .308.

+/- 4" MPBR out to 350 with hunting rifles.
