20 inch vs 24 inch tikka 6.5 creedmoor

Heaven forbid you suggest a 20” PRC!! Apparently any 6.5 PRC needs a three foot barrel and anything less is totally crazy!

[6.5 prc in a 20 inch barrell
Correct - why get a cartridge that by design is supposed to have a long barrel and send a 140g bullet north of 3k fps. In my mind, it doesn't add up. I get why someone may want to reduce barrel length but the reality is, 4 inches of barrel weigh an extra sod all if weight is the concern.

I've currently got a 20 and a 24 inch barrel on two rifles, none cause me any drama. The rem mag had a 26 and a long moderator which probably added another 7 inches. Still, no dramas with it.
 
Interesting question… my understanding of the science is yes inherently more dispersed then longer ones although in normal practical terms this is very hard to define and probably irrelevant in common lengths of barrels. I am hoping someone clever will come along and explain the science behind it but I’ve read that in a few places but I’m not absolutely certain. It’s not really helpful information anyway as generally good quality long and short barrels shoot fine.
Just remembered….Secrets of the Houston Warehouse….might be worth revisiting?

I think it was something Ed. Bewsher wrote recently about one of his rifles that shot very well but he would have the barrel shortened if he was sure the accuracy wouldn’t be compromised.

I use a 20" 6.5CM with 143ELDX or 140ELDM. This yearling shot at 614m had a very similar exit wound to the other shot at around 15m. With a 24" one could go out even further?? BC values of the ELDM or X are really good and retains Energy well.

We did a day's testing and documentation of comparing stainless T3 CTR 20" 308 vs blued T3 Lite 20" 308. Result was CTR 0.23MOA, Lite 0.35 MOA using Factory Sako 168 Match ammo. Only ammo we tried in the Lite. I'g go Lite if mod is being used.

How much weight are you realistically saving? 24" is optimal for 6.5cm surely losing a few oz isn't as important as having your rifle perform to the best of its ability.

Weight vs muzzle velocity?
Weight isn’t the issue. Length is.

I shoot roughly 50/50 a 20” and a 24” barrel.

The 24 is a pain in the ass in woodland or from a vehicle

Simple maths. So you can have a short barrel and still have the velocity you want for the distance you need.
 
Too loopy, too heavier bullets bouncing around in the dark - fast, flat and frangiable for me at night
It’s not really though, is it.

95gr vmax at between 3050 and 3250 is more than flat enough to any sensible range at night. And is very frangible. Though any shot that’s not safe with 143gr from a 6.5 is also not safe with 40gr from a .223!

Moreover, with the advent of thermals equipped with rangefinders, it doesn’t matter how loopy your trajectory is.

Each to their own, just my preference. Lighter bullets definately bleed energy after first impact than heavier bullets. And deer bullets pass through foxes more than deer. I like to have separate foxing and stalking setups, optimised with suitable projectiles, and properly zeroed. Yes you can have multiple Zero’s and modern tech has changed the game, but separate setups for me is the way i like to do it. Heavier bullets for deer, lighter bullets for fox. Just the way i do it, other ways are available but i see them as a compromise.

A loopy trajectory might matter if you miss your intended target.

I run t3x superlight in 65CM, it’s 24 inch barrel, if you carry barrel down you really need to be quite tall (I’m 6ft and potato fields are a pain)

I remember the days years ago if you said you had shot deer much past 300, admin would ban you because it’s a stalking forum 😂
 
Anyone used a Tikka T3x CTR as an all purpose stalking rifle?

Or stick with the lite?

I use both a Tikka UPR and a CTR for deer hunting. I hunt from tree stands and box blinds so my style of hunting is stationary. The extra weight of the rifles allow for steadier holds and more precision.
