Load needed 300 win, rl22, 220gr. partition
Merry Christmas

Just received 50 220grain Nosler Partitions for Christmas.
I have Reloder 22 and would like a max load for this combo.
Anyone have the specs handy

Thanks in Advance

Steve's pages say 72.5gr. RL 22 using 220gr. bullets.sakofan..Retumbo might give you great speed with that bullet..

Quickload indicates 74gr RL22 will give you 2870 fps, and 62317 lbs-psi with a COL of 3.34" and 26" barrel.

As always, back off a few grains and work up.

I have got to admit as having pushed it farther than Montana Marine's listed load.

My usual load with a 220 grain Round Nose is 83 grains of H 1000 that I saw in an old reload manual at some gun shop one time. The book was not for sale./

Got home and tried it. Definitely a flat shooter, even with a Round Nose to 300yds. Chronographed velocity out of a Browning A bolt with a 26 inch barrel was 2975 to 2980.

When it hits the gongs at 300 yds, it still makes quite the '"clang."!

Holy Toledo, Seafire!

You must have a very generous rifle. I was blowing primers with 82 grains of H1000 and 180-grain bullets.
