Why shorten?

That depends on what your goal is. Going bigger has a limit/downsides.

Presumably you've confirmed this with a rangefinder?

Also I was used to a shorter barrel after my AR15. This rifle is my main rifle these days and I primarily use it in bush hunting situation but have no hesitation using it out to about 600 metres if the wind isn’t too boisterous. Certainly didn’t lose any noticeable accuracy at normal hunting ranges and is good enough to use out to 600 yards on local NRA range and hold it’s own with competition. In short, I don’t feel disadvantaged by having a shorter barrel on this rifle. The same can be said for some of my other rifles. I have three 308’s with barrels ranging from 16”, 18” to I think 22” and they all shoot well enough for my needs. As an aside. At the range on the weekend, switching tailwinds all afternoon. I shot first round of 10 shots at 300 yards with 223 and did better with this than my 24” Sig Cross 6.5 CM in second round although third round the Sig did sort it’s shit out. So again I don’t feel particularly disadvantaged running shot barrels and I don’t load for maximum velocity but for accuracy. Run what you like and suits you. Also, maybe throw your chronograph away. Especially since the Garmin has come on the scene, they have ruined many a load that has worked perfectly well until the shooter has seen the velocity wasn’t what they expected. You still have to check drops the old fashioned way anyway. Just my thoughts this rainy day.

We're we at the range together :)
Man 223 at 600 - colour me impressed..I cant see that far lol. What projectile? Twist?

“Man 223 at 600 - colour me impressed..I cant see that far lol. What projectile? Twist?”

Supposedly 1:8 but measures closer to 1:9 with cleaning rod but whatever it runs 73 gr ELDM’s ok. Handled some 77? gr govt Belmont ammo ok, only shot those at 300 from memory. Out of interest I’m currently using a 4-16 GPO scope but generally a 3-9 Nikko sterling lives on that rifle. 600 is getting out there with the NS though.

I'll shoot mine at 600M on our range just on paper.

It seems futile for a person who has no legal option to use suppressors to be commenting on their merits

After yesterday's disaster they may be down to bow n arrows soon....

Which part?

Ive measured my practice area where my targets are set up. Sometimes I take a rangefinder hunting. Sometimes I dont. My system means there is room for error.

Bow hunting is already banned in South Aust.

Not allowed to hunt with them unless you have a tan.

Tan comes in a spray bottle..... Head down arse up and hope like hell cool heads prevail.

Factory 7mmrem mag looses about 300fps from 24 inch down to 18 inch. You have lost all the advantage of such a rifle in that scenario while retaining the powder burn and recoil. And still 90% of animals are shot under 500 yards.

Added to that, by shortening and losing velocity then more drop is introduced at the same distance and to my mind, more drop equates more margin for error....
