6.5 PRC Pressure signs

Hi,
I’m new to reloading for rifle calibers. I’m using White River Large Rifle Magnum primers, virgin Norma brass, 56 grains of N560, and 147 gr ELD-M bullets. The bolt lift feels heavier than with factory loads. The rifle has about 100 rounds through it. Are the extractor marks on the cases a cause for concern? Average velocity is 2901 fps.

Rifle:
Howa 24"
Long action
Suppressed

You're charge weight of 56 grs of N560 fills Norma cases just fine and normally shouldn't produce a pressure issue, though that charge is just a bit on the warm side. But those ejector marks are a sure sign of over pressure that needs to be addressed. I think you have a combination of things, the main one being the use of magnum primers. With this size of cartridge, there's really no issue where you've need to use magnum primers with a powder that as fast burning as N560. . . unless you're shooting in very very cold conditions that might effect ignition. I've never used magnum primers in my 6.5 PRC and great performance out of standard LRP's.

If these were shot in pretty warm/hot summer temperatures, it would contribute some to increasing pressure since your load is a somewhat warm charge to start with. Then being suppressed can add to that too.

Nice saw. My all time favorite was the 038 Farm Boss. They gave them to the limbers but I bought one for myself, plenty for home use, tough as nails. Small enough to be easy on you but powerful enough to cut a good sized tree.

The toughest I ever ran was a couple old Homelights. That was back when Homelite and McCulloch were the only options, Stihl was just getting known and Husky hadnt come over yet. This redneck kid was cutting a 3' Red Oak with a big old Homelite and when it fell it twisted and caught the bar, jerked the saw out of his hands, and butt stomped the saw hard. Bent the bar and the handle badly. He went to the truck, got a crow bar, straightened the handle, put a new bar on it, pulled the cord once and she cranked right up. A Stihl or Husky would have gone to the dump.

Ah! The good old Homeheavies! I can still feel phantom vibrations in my hands along with the carpal tunnel from cutting miles of fire-line with one.

I still have my Sthil O44 and it runs strong. It Defenitely out performs my dad’s little homeowner grade saw.

What's the best weed killer?

Seriously, you need an excavator or bobcat to rip the entire root ball out. There is a plastic barrier that landscapers sell specifically for bamboo that you bury that goes down 3 feet or so and sticks about 4 inches above the ground. The root rhizome can't get past that.

You need to get a mini x and dig out ALL the roots, then trench along the property line and put the barrier in. No amount of weed killer will fix your problem otherwise.

Well at least I do own a mini x. This infestation is in deep forest and jungle. This will probably take the rest of my life, I'm going on 65 now...
Like Bartles and Jaymes used to say, Thank you for your support.
