Dennis,

I have shot The Cast Bullet Shops bullets four years now. Between Elaine and I we have put 1000 + of his gas check 200’s down range cast from his MA alloy. I have shot through an entire Western National CLA Match with no cleaning and no lead when I did. Plenty of heavy black fouling from my 5744 loads though. I have them sized .359 which seems a happy diameter in our Uberti barrels. I’m not a very knowledgeable cast bullet person and Tony has been very helpful and patient talk me through my ignorance. If you do place an order typically you go on a list and your bullets get cast when your name comes up. Best to plan ahead. I order about now for what I want in the spring. Tell him you started this current trend and we stole the whole idea from you. He has been pleasantly surprised to learn his bullets are performing well at 200 yards from lever action rifles. I’ll give VV 3n38 a try.

6.5 gr is a good starting point

My current load data shows 7.2 grain of VV 3N38 behind a Matt's 205 grain bullet, so a subsonic load.

I like to use Remington 6 1/2 primers, they usually give me single digit or very low two digit SD's

Never tried supersonic, but maybe one day.

Also a new favorite powder is IMR-4227, better than I remember from 20 years ago, cuts very clean in my Redding powder measures.

Works great in my 44-40, sad I'm selling both for my rifles soon, trying to raise money and cut down on my shooting gear.

I just recommended to a friend to also try the Sierra 180gr FPJ bullets, he was having trouble with some rams in Florida and didn't want to hassle with the difficult seating of the 200 gr 35 Remington bullets or buying a new 30-30 rifle. The 180 FPJ bullets were made specifically for the handgun silhouette version of our sport for the rams. Of course supersonic for these, but less recoil than a 30-30 for sure.

As always, be careful with any reloading data some yahoo, like me, starts telling people on the net.

Why don't people seem to favor a sub PC load for .357mag out to 100m?

My original load of 6gr titegroup with 125gr XTP bullet gave me a velocity of 1353 FPS and putting that in a random online calculator it does or has a chance to go transonic when it reaches rams. I figure why risk that even if they still hit and knock down the target?

In the next couple of months I plan on doing 5gr Titegroup with a 158gr XTP bullet, I was getting 1030 FPS with a very nice grouping.
4.8gr of Titegroup gave me roughly 950 FPS and another nice group. Both are using pistol magnum primers. 24" barrel.

I am getting 30 for standard deviation which is high...( but do you think it's an issue if only out to 100m) I'm going to be trimming my brass and try to make sure things are as uniform as possible, but I wonder if this is part due to the large case and small amount of powder? I also got a separate crimp die despite having trouble noticing a crimp on a case... Should I angle my rifle up and slowly lower to think the powder will be at the back of the case? Some things I plan on adjusting in the next couple of months.


Am I wasting my time? Am I making things way more complicated then it needs to be for a simple PC match? I don't know why I'm so stuck on Titegroup, I just want to choose something and not have to second guess things in general. I go with the XTP bullets because in my mind having a jacketed bullet helps with the momentum energy?
