Thread: Primers?

I have not reloaded yet, but I am planning to start shortly.

This may be a dumb question, but I have googled in every way I could think without getting a definitive conclusion: if I reload the brass recovered from Hornady factory ammo, is it Large Rifle primers that I need?

From a couple of different forum threats people seem to use CCI Standard, CCI BR-2 and Federal LR Match primers together with Hornady brass.

The original factory ammo where the brass came from was:
- 6.5 CM 129gr Interlock
- 6.5 CM 140gr ELD Match
- 6.5 CM 143gr ELD-X
- 6.5 CM 147gr ELD Match

Thanks!

Federal LR for best ignition.

Thanks @TeRei,

Would you recommend the Federal LR Match or Federal LR no.210?

Couple of other things to consider, how strong is your primer strike from your firing pin.
What type of powder are you going to burn.
Some firing pins fall lightly such as the standard Tikka, so Federals would be a good choice for them.
Some powders like a hot igniter like a magnum primer. W760 powder is a classic for needing hot primer ignition.

Or you can safely use CCI Magnum primers. I use these in 6.5 with 143 Gr ELDX.

Jan,

A simple way of checking which primer to use for a particular cartridge is Wikipedia
https://en.wikipedia.org/wiki/6.5mm_Creedmoor

It is worth experimenting with a couple of different manufacturers to see what gives you the best results

"Match" primers are the same as "normal", but have undergone more stringent quality control processes.

For most hunting applications, a normal primer will be fine. If you get into serious target shooting like F-class or benchrest, match or benchrest primers would be worth it.

If you do decide to use magnum primers, remember to use a lower starting load when testing.

Thanks John,

Will use H4350, and shooting from a Howa. Do not really know about the strike from the firing pin since I do not something to compare it with. This is what the strike look like on factory ammo:

Will do more target and F-class shooting, so looks like match or benchrest will be my starting point.

i use 210 in everything except my 264wm then i use magnum primer

Don't commit to the 147's ... unless you get a custom barrel/twist.

I have yet to find a 1:8 that can stabilize a 147 ELD

Makes sense. My Howa (standard 1:8 #4 barrel) likes the 140 ELD-M and not the 147 ELD-M so much. I do not have a huge amount of experience testing either, but based on what I have seen so far I will start with loading my own 140’s and leave the 147’s for a future project.

I have not given up on the 147's yet, going to try them in my 1:8 5R IBI DMR Match barrel STAG10

My CTR Build def does not like them much.
