Got a tikka 595 to rebarrel and looking at options.
Ideally something simple with some legs for 600m hunting.
Would you go 260ai over 260? What's the potential speed increase?
Also anyone know if t3 talley rings fit the older 595?

50 - 200 fps difference.
I would you can still use 260 ammo in an ai chamber.
Get a stug stock man way nicer then the factory plastic.
Not sure on rings
Nah it should be fine. Neckshots is only doing like 2600 from the barrel and as everyone knows it kills well.
The 'sweet spot' is .... 7mm08
:thumbsup:
Straight 260 don't bother with ŕcklying. But legs out to 600m with good killing power I'd go 7mm rem
140 gns kill fine 500 and under.
[QUOTE=199p;250322]Nah it should be fine. Neckshots is only doing like 2600 from the barrel andas everyone knows it kills well.
bro!!!.mine are doing:) 2850fps
2850? how hots that? I've read that people are getting 2950. how longs your barrel Neckshot?
That's a personal question only my wife gets to ask :D24 @R93 is getting 2950 with RL 17. my speed is my hunting load if speed is what blows your hair back by all means chase it.but for me speed isn't what's needed for a hunting load its accuracy .Quote:

maybe 7x57 if the action is long enough could be another option I just thought of james
.308 has been killing stuff a long way out for a long long time, there is NOTHING a .260 (or AI ) can kill at any distance that a .308 cannot, 178 Amax doing 2700fps kills big stags at 700 all you need is accurate range finding and exact understanding of your ballistics, no different to any other calibre. I can get the .208 Amax doing 2500fps and the drop and drift are an interesting comparason with lighter projectiles starting much faster. The .260 delivers less killing energy at close ranges also, 130 TTSX is absolute dynamite out to 300yds. Don't go .260 or .260 AI because it better at killing than a .308 cause it's less than, not more. Go .260 cause the calibre appeals for whatever reason.
If you really want something different, .270 Redding or .270-08, just happen to have a .270 stainless barrel doing nothing..........
rifle needs a new barrel as it's lost accuracy and another 308 barrel is plain boring. 7saum is what i wanted but i hear that it will be a bit complicated.Quote:

+1 284 with the 150 lrab and 20inch barrel rl17 should get you 2800-2900 easy.
260AI if my 243 barrel wasnt so damn accurate it would be one by now
Thanks for all the feedback, Tuiman has come to the rescue and will help put together what i wanted. 7saum. Stoked.
Good stuff abe
New barrel shot the 125 partitions today @ 3125 with no pressure signs using my pet load. Just neck sized 3 firings. Seated to mag length.Quote:

Biggest load of shit I have ever heard that 6.5 projectile is a slow killer at range. Not in my experience at all, try using the right projectile.
In saying that my .260 AI will never have its legs stretched on animals.

He's good like that and good choice on the saum mate :cool:Quote:

Just what I read. I'll have to test it for my self when I get a scope that can dial on my ai
If a 7mm 120 and a 6.5 120 both going the same speed, would the 7mm 120 have more energy/knock down power
Just thinking along the lines of dropping 2 balls into water the same weight but ones fatter then the other wouldnt it displace more water making a bigger wave, so the same would go for an animal?
Should be some smart people here to answer that for me
i done a wee bit of playing on jmb for james (Freezer) yesterday
I looked trough the data and found the loads producing the slowest speeds (worst case)
* 123 A-max @ 2735 (slowest load for a 125 so would be going a little faster for real)
* 130 VLD @ 2735 (again a 125 load so would be going a little slower for real)
* 140 A-max @ 2510
* 140 VLD @ 2510
when that data was punched into jmb it told me there was enough energy out 500 working on the 1000 ft lb mark the 123 has 929 ft lb but imo that would still be ok with proper shot placement..... and the rest were better than that
so shooting the same pills at max speeds 260ai would be sweet out to at least 550 imo
anyway he is getting a saum now and that will piss in:) good on ya abe:thumbsup:
Unless the two balls dropped in the water were made from different materials ( thus different volume) then they wouldn't displace any more area than the other.
2 projectiles of same materials with equal weight and velocity with have very similar results in an animal.
Have you been reading the terminal ballistics website again Toby?
I used to think along those lines as well. But no. The only difference is a minuscule amount of diameter.
In my experience every animal is different. Doesn't matter with what or where they are hit, they can react differently.
People try to apply science to it, but in reality it is a totally different.
Get out and shoot some game with your new rifle and in time you will most likely come to the same conclusion.

To answer toby if two projectiles of the same weight are going the same speed they have exactly the same energy, regardless of surface area. The smaller diameter pill will have a higher sectional density therefore should penatrate further.
Energy is the same, but the practical question is how do they transfer that energy to an animal, and how does that translate to killing effect?Quote:

Bullet construction. Not all are created equal.
