Hi Friwi,
Any chance you can share a bit more about what you shoot with - brand, barrel length, optics.

Anything you plan to change on your current setup?

Hi,
First I am not a hardcore weekend competitor. I just shoot at my local range and. I sometime participate in a local match when I feel like it.
My rifle is a tikka 590 into a heavy laminated stock. Barrel is a 27" true flite ultra match. First barrel ever chambered by true flight in 6.5 creedmoor at the time.
If I wanted to be more competitive, I would go Barnard -S or P action. In 6.5 I would try to use the 147 gr Elm, ( so 1 in 8 twist) seated into a 6.5x55ai or 6.5-284 case. In 7 mm the 284 case as stated above.
If you want a barrel that last you more than 1 season then yes 6.5 creedmoor ,6.5x47 or even 6mmbr.

shooternz : what powder/primer/case were you using in the 6.5x55?

I like 6.5 Creedmoor, but looking at for example the Seddon Rifle Range rules, it states:

“Ammunition that exceeds any one of the following performance are not authorised for use on Seddon Range:
a. A maximum muzzle velocity (MV) of 1,000 m/s (3,280 f/s),
b. A maximum muzzle energy (ME) of 4500 J (3,319 ft/lbs).”

Some of the Creedmoor ammunition could be non-compliant, so how a big limit is it?

As others have said the 6.5 Creedmoor will not be an issue, basically any non magnum 6.5mm, 7mm or 30cal will be well under those limits and a fair portion of the magnums will also be safe.

6.5 Creedmoor is a great starting cartridge, the availability of affordable match ammo is a massive advantage to a non-reloader and even an advantage to those who reload.
I personally own a 260 but if I were buying a new rifle the Creedmoor would be on the list.
6.5x55 is also a good cartridge, definitely not a new sexy cartridge, but a good performer with plenty of factory ammo available and lots of reloading data available.

If you are going to be reloading the 284win is a great cartridge, good ballistics, good barrel life, not too much recoil, good availability of dies (and brass to some degree), biggest issue is it's definitely a reload only cartridge.


If the rifle is going to be a purpose built F-class set up, I'd be going for a 7mm and go for the 284win.
I don't own a rifle in the caliber but a friend does and it's a great performer.

Thanks Beetroot. Valuable info and advice!

Yeah 180's at 2900 make a fairly compelling case.

Out of interest and not wanting to drag this off topic, but do we have any 6mm Creedmoor shooters yet?

Have seen a few in the states running them and it sure does look like a neat round!

I have a RPR with a SS Proof 6 Creedmoor barrel it goes very well

The Hornady factory ammo I have tried shoots very well in it

I have had a reamer for ages, https://www.nzhuntingandshooting.co....8-tikka-24749/

Lapua even make brass for it now

Some ammo are available at the local gun city. But except a few ruger Prc I am not sure if there are many reamers in the country for that round.

I have a 6mm Creedmoor barrel for my Bighorn switch barrel rifle. Running the 110gr SMK's with hardly any recoil and pretty impressive ballistics. It's set up as a PRS style rig rather than F Class

Thanks The Claw.

What is the main difference between a F Class and PRS rig?

How big is PRS in NZ if you want to get into it competitively?

They are totally different beasts.
F class is basically fullbore NRA shooting but with a scoped rifle and any calibre other than 308 or 223, they both have their own class (F-TR). You shoot a big paper target from prone, one shot at a time for 10 shots at a set distance, highest score wins.

PRS is a totally different ball game.
It's practical shooting, mostly steel targets shot from a variety of positions (stand, sitting etc), with a lot of different barricades or obstacles to shoot from/through, set out isn a series of stages with different targets at different ranges from the same or different positions.

PRS is huge in the USA with a national series with big sponsors, here it's a matter of finding some local people who run events.
Some NZ events are shoots that have been going on a long time and have sorta just been wrapped up under the PRS umbrella.

F class has clubs throughout the country who belong to Target shooting NZ and operate club days and regional competitions, with a NZ competition held at Trentham each year. It's a much more regimented affair with strict rules, but a lot of club days are pretty casual and friendly to new comers, obviously dependant on the club.

Thanks Beetroot,

Is it possible to get rifle setup that will good for both F-Open and PRS style shooting? If so, can you describe it?

In my very limited understanding I would think that for F-Open you would go for heavier and longest barrel with a very sturdy stock. Not a rig you want to move around with.

For PRS - probably something that is more mobile. Long barrel but not ad heavy.

Or do I have a miss-conception of how the two differ?
