Standard or Mag primers for RL 25 and RL 26.
Anyone have any hands on???
Thanks,

Jpretle,

No experience with RL-26 but I have used 25 and used Fed-215 primers with good results. It was in a 8mm Rem Mag so I was igniting a hat full of powder.

In my 7MM Mag with 160gr Accubonds I have found
Winchester WLRM primers give the Smallest ES of all
the primers I have used. With the 270 winchester and
257 Roberts, I only use Winchester WLR primers. Does
not seem to make much difference.

I use Federal 215M primers on any cartridge that I use RL-25 in. Never had a problem.

In my .270 and .25/06 I use the Fed 210 Match with RL-26.

In my .300 Wby I use the Fed 215 mag.

Fed 215's with RL25 in the 7 RM, 7mm Dakota, and 7mm Mashburn Super.


Oh.....and the 270 Winchester as well.

The real question is has anybody TESTED various primers against each other with these powders?

If it's a ball type powder I'd start with a Mag primer, other wise something colder like a CCI200 in a 308-30.06 sized case.

I haven't tried different primers with each ball powder, but I always use mag primers with slow burning ball powders. Powders like Tac light easily with any primer.

Here is some load data for RL-26.

I've been using Fed 215s with RE26 in 270 WSM, 300 Win Mag, and 7mm RM. I tried WLRs in the 270 WSM load and while I had good ignition the group size was a bit better with the 215s. I've only loaded RE25 in a 270 WBY and with that I use the Fed 215s as well.

I've always stuck with under 60 grains gets regular primers and over gets mags. I tried CCI250's with RL26 in the 243 and 25-06. In both of those, in my small sample, CCIBR2's edged them a touch in accuracy.











Speeds weren't hugely different either.
