6.5 Creedmoor

[Eddie 359]

I have been reloading my 6.5CM for a few months now. Due to a lack of powder I’ve started building a load using Hodgdon 4831 SC (not a typical powder for this caliber, but data is available on Hodgdon reloading site). The Hodgdon date for a 140gr Hornedy ELD was from 39-43.5gr. I am using Lapua brass with small primer pockets. I am also using a Nosler 140gr RDF projectile. My first shot (41.8gr) blow a hole in the primer. Velocity was just over 2600fps (within expectations) and hit very close to point of aim. Not sure what to think of this. Any constructive feedback would be valuable. Thanks in advance.

What rifle? You may need a small diameter pin for small rifle primers. Also, who's primer is that?

 

[Eddie 359]

The rifle is a Winchester 1885 Highwall. The primers are Remington No. 6 1/2.

Maybe try some LRP brass or factory 6.5 Creedmoor.

Having no issue with Nosler brass w/large CCI 200 primers

The rifle is a Winchester 1885 Highwall. The primers are Remington No. 6 1/2.

6 1/2 primers are meant for low pressure applications like the 22 Hornet. They are too thin for Creedmoor use.

Thank you! I’ll try some CCI 400

I’d go with 450s

Yeah, use the thicker primers or better yet the large priers like you found out already.

Id like to see this 6.5 high wall! I hope you have a tangent on it somehow.

Already been said, but yeah needs a heavy duty primer.

Sorry it took so long and sorry no tangent.

That’s a nice looking rifle and not nearly as ridiculous as I was imagining lol

Possibly the least gay 6.5 CM in existence!


As mentioned, use appropriate primers.
