I'm loading Berry's 158gr plated, I'm thinking to only use the Low to Mid Range at most with unique so I won't have to put a heavy roll crimp, That might seperate the plating. Any Thoughts or anyone use H110 on plated bullets?? Thanks In Advance ; )

Sounds like a good plan with Unique.

Using H110 doesn't though.
You can't safely reduce it very much from the listed MAX load, and that is usually too much pressure for a plated bullet.

Ditto.

Accuracy falls off with Berrys bullets if you drive them too hard.

While I am certainly a Unique fan using it on the low side burns pretty dirty IMO.

With Berrys Bullets in my Glock .40's, I got better accuracy with mid/low range loads using Unique than using faster powders to achieve the same velocity. I say stick with Unique here.

You can crimp pretty hard & not separate the plating from the lead.

I use a pretty good roll crimp on my revolver rounds.
And had a few where I had to pull 'em (upside down primer etc).
It leaves what looks like a nice cannelure, but I've never had separation.

Won't grumble about my former Lee Pro1000. Atleast not in this thread.

You can always crimp over the shoulder of the bullet, not having to worry about the plating at all.

Wouldn't that look weird? Looks matter.

Whenever I get a call about poor accuracy with our bullets the culprit is nearly always too aggressive of a crimp. The deformation of the bullet creating a waistline with a bulge usually below the crimp line. Just pull one after crimping and see what you've done to the bullet.

That's a good story line, but I had significant decreases in Berry's accuracy (.40, stock Glock barrel) whenever I drove them too hard. The crimp was always a light taper crimp, just taking the bell out. I never adjusted the crimp die.

I bench tested this several times with the same results. It wasn't the crimp.

Too fast does diminish accuracy in many cases, but I shoot a 155gr HBRN in my 10mm at velocities of 1250 fps with great results. Most of our competitive shooters feel the heavy and slow combination for accuracy and speed. Most of the tech calls the customer is using mid-range loads so it usually points to the crimp.

I shoot a lot of cast lead, and Berry's are a favorite of mine.

Rightly or not, I put a very gentle crimp on them, almost undetectable.

At reduced loads, some powders are very position sensitive. You'll get quite a different result if the muzzle is raised into shooting position (powder forward in the case) vs. if the muzzle is lowered into shooting position (powder in the rear of the case). Some powders are very sensitive this way and others not much or at all.

TiteGroup is not position sensitive. But it is pretty sooty.

I get good results from Universal powder. It does not seem to be position sensitive, and it is not as sooty as TiteGroup.

Does the 45 Colt look weird?
