New Bullet Needed For 6.5 Cal!

[ChrisNZ]

So, on the surface the 6.5x47 appears to me an under capacity, under primered cartridge in 26cal. This of course is why so many are going 6-6.5x47L. As such, I predict it'll do well only at medium ranges, or on easy 1Kyd courses -on good days.

..
There must be basis for use of the 6.5x47L beyond it's intended -medium ranges. But I'm missing it.

The small primer certainly is no handicap Mike. Accuracy results have proven that definitively.

The 6 Hot is certainly a good cartridge- my clubmate got second in the Grand Aggr with one at the recent NZ Nationals. He would have shot his 6.5x47 had it not been for a projectile shortage.

BTW, the winner used a 6.5x47L, beating all the 6.5-284s

Ignition efficiency aside, there is one disadvantage to small primer high-pressure cartridges that I didn't realise until I had my .308W FN SPR (Win 70 WSM receiver with a 0.473" faced bolt) rebarrelled to the cartridge - primer extrusion and piercing. I just can't get anywhere near the MVs other people claim with the cartridge before I pierce the caps.

Mind you, the FN / Winchester seems to have a massive firing pin tip diameter even compared to a Remington 700, although I've never measured them to see how they compare. With hindsight, I wish I'd gone for 6XC with its large primer.

That's why I chose a Barnard Laurie ;D

Ha! Smug Kiwi g*t !!

No, I don't really mean that Chris. I've one Barnard Model P based piece and a second on the way. If I could afford it, all my rifles would have the action.

However ................ by a twist of ironic fate (or Laurie-incompetence if you're less charitable) both Barnards are chambered for rifles with large primered cases, and my .223 Rem, 6BR, and 6.5X47L rifles have Savage, Remington and FN / Winchester actions respectively. The Savage 12 Competition action seems to be the best of the factory designs in this regard, although the Remy 700 does very well indeed with the BR, although I can't run at the loads and MVs listed on the main website.

Mind you, going back to some of the points in other posts, it does wonders for barrel life running at 100 - 150 fps below what is theoretically possible.

This is not a basis for anything..
And you will not skirt around reloading 101 with mere desire.

The 6.5x47L isn't imune to pressure, I assure you.
I have to size & bump both 223Rem, and 6BR,,, just like my 6XC or 6.5WSSM. Both 223/6br with Lapua brass/small primer pockets.
And with stiff loads, small cartridges see pressure problems and extraction issues just like larger catridges.
So if this cartridge is to be consistently competitive, it's not a question of bullets. It's more a question of increased extraction leverage, and brass supply..
Otherwise you'll be fighting a bolt turn click while everyone else is puttin em downrange.

As far as accuracy, I'm pretty sure consistent 1/2moa is competitive in 1kyd competition. And that's gonna be tough for your slow little bullets in the wind.

Well I guess it all goes to show you can't buy a result if your wind-reading skills aren't up to it.

I'm not claiming the 6.5x47 is in any way magical but it sure is efficient. Bit like a bigger version of the 6BR.

Jeff ................ providing accuracy is as good as with a top-notch lead core bullet.

As you say, that's the question. The interesting scenario would be if accuracy is 'good enough'.

Hi Laurie , i think your above statement holds all the cards.. In my events one has to have All the shots in the right place and close together because there are two events on at the same time ,one for group and one for score. In group events no one hands out wins for the best nine bullet holes ,it has to be all 10 and as my home range simply hates the fast twist High BC looong skinney bullets .. When our shoot days are at their worst with a strong following left/right fishtail wind the 6/6.5mm guys with the 8twists and VLD bullets go home with their tail between their legs .. I see it as only being worse for the requirements of the mono bullets .. As a matter of fact i would not shoot any cartridge that needs faster than a 10 in twist .. My rifle uses a 13.5 twist for just that reason , in recent years events i have a 94% 10 ring score rate over the whole year at 1000yds and that 10 ring is 7 inchs in dia, all this done with a bullet of .525 Bc ,, So no i remain unconvinced ,but hey it takes all types to make up a world ,hey..JR..Jeff Rogers
