Load Data for Berry's Bullets? (148gr HBWC)

[Josh A. Grossman]

Well I loaded some Berry's Bullets (copper plated 148gr HBWC) in .357
magnum cases with 3gr of Bullseye, and they key holed at 25 yards, and
I could not get them on the paper at 50 yards. So then I tried 3.3 gr
of Bullseye, and the key holing went away, but still not accurate. I
guess I am going to load some at 3.3 and some more at 3.6 and test
those loads.

Anybody out there already have a super accurate load with copper
plated 148gr HBWC in a .357 case using Bullseye?

Thanks in advance,
JAG

Any chance that the copper plated bullets aren't obturating completely
with a charge that would work with soft lead. Might need a fairly stiff
charge of B'eye to equal the performance of a lead HBWC ahead of 2.8 gr.

There is a note on the Berry's website about these bullets, they have
to be pushed to 800 ft/sec to be accurate.
I am going to load some up with 4gr of Bullseye tonight, and hopefully
get a chance to test them over the weekend.

Copper-plate!=swaged lead. Coefficient of friction is higher and the
whole slug would be stiffer. Kind of defeats the purpose of a mid-
range wadcutter if you have to go to a heavier load just to get them
to take the rifling. Midway still has the Rem HBWC, though price is
up, again. Also, might be time to slug the bore and measure the
chamber mouths. If you're keyholing, sounds like the slug might be
too small for the bore.

I have not used the hollow base wad cutters and fired very few of the solid
base units. I did shoot some hollow base Miniballs in a muzzle loader. I
was under the impression that the wad cutters were not accurate much past 50
yards.

Sounds as if he is having the same problem with them when I first started
firing hard led SWCs. I switched form jacked bullets to the SWC for cost
years ago. The first ones I loaded were not accurate at 25 yards. As I
went up on the powder charge, they got beter. Finally around 1000 fps or so
in a 357 cal revolver they shot very well.

I don't understand the hollow base and hard lead/plating either. I thought
the soft lead hollow base was so you could put about 2.5 to 3 gr of Bullseye
behind them for light target loads.

Well I loaded 50 up with 4.0gr of Bullseye and 50 more with 4.4gr of
Bullseye, I will test them and let you know how it goes...

Apparently it didn't go well and it blew up as to why he never got back to us ????
Anyone do well with these loads?
