Cheap .30cal Heavyweights

[RL338]

220 grain at 3000 fps is a wrecking ball.

9lb unbraked 300 Wby with that load is like a wrecking ball

And those loads definitely have the cool factor going for them too.

This evening I moved onto the 308 Win. with these. Goal I set was 2500fps. Powder I used was Superformance with Alcan LRM primers. I only had some odd and end brass laying around. 1 group has 57.15grs H2O and the other 58grs H2O. I used the 57.15 for pressure test. Started at 41grs , way slow. Moved up to 46grs , getting there. 50grs is where it’s at.
41grs - 1893fps
46grs - 2198fps
50grs - 2509fps
51grs - 2522fps
52grs - 2590fps
I loaded all brass at 50grs with 1/4 turn crimp.
I fired 1 round of 58gr H2O brass , was a little slower as expected.
50grs - 2469fps
Just for fun I checked how much of Superformance a fired case holds.
57.15gr H2O holds 61.0grs
58.0gr H2O holds 62.2grs
I will get these in paper at some point , hopefully it will match the 30-06 results.

308 Win 220 gr Sierra Pro Hunter RN at 2400 fps with 44.5 grs CFE223. The bullet went through 5 jugs and was caught in the cardboard as shown in the picture below.

With that momentum of 220grs , it’s quite a thumper round.

I should imagine that mass pushed at that velocity would work for a wide variety of heavy game.

my cheap heavy 30cals are lapua's

For whatever reason, I always figured to load these in a .300 H&H if I ever got one. Its a great deal on the bullets in any case!
