6.5 PRC, N565 OR H1000 that is the question

[Longtine88]

156s @ 3120-3140 in a 24" prc. I can barely even run those speeds in a 6.5 max case with 10gr more capacity from a 26" bartlein

Got to hold your tongue out when loading lol.

N560. N565 I actually lost about 15 FPS. N560 was hands down the winner. It's a hunting rifle so it might get shot 30 times a year. My other three I'm getting 3120 to 3140 out of a 24" with N565

Are you using a +p chamber?

 

[Longtine88]

Yes my other two are plus p barrels (Should have stated that sorry). Their not as accurate but faster. Brass only last about 3 loadings and it's toast. If I had to do it over again I'd just stay around the 3,000 fps mark with that bullet. I don't think a mule deer is going to notice the difference lol. I have a barrel spun for 6.5 max and I am going to play with it this fall. See if the brass holds up better.

Why does the VihtaVuori website have load data for 6.5 PRC that shows:
140gr bullet - N565 starting load 44.8 gr and max load 50.0 gr
153gr bullet - N565 starting load 46.0 gr and max of 52.2 gr

it doesn't make sense.

Look at the COAL. Big difference.

Look at the COAL. Big difference.

So what does that mean though? Why do they have such a short COAL? Is that the max charge they can get into the case at that length, or are they saying that's max pressure?

 

[Rhett Crider]

I don't use Lapua bullets but OAL of bullet makes a difference. What are you planning on using? And what;s your COAL? This might help.

The 140 Hornady GMX is a monolithic, solid copper, the 153 Atip is a very long bullet

That makes sense. I'm not sure yet, waiting on the barreled action but most likely a 130 or 140 accubond type hunting bullet, possibly 127 LRX, and at least 2.95 COAL. Thanks for the info.

 

[Rhett Crider]

I use N560 w/ 156Elite. N565-may need drop tube.

 

[BrentM]

Those vv numbers are for typical European bullets and solids. Long bearing surfaces and ultra safe loads create a low charge and velocity range. I can't even look at their data any more it is so whacky.

Likely because of hardness differences in the two. Mono bullets can raise pressure more than lead core bullets. I have found the VihtaVuori numbers to tend to be very conservative.

I don't think Berger or Lapua use V V data
