Looking for a slow ball powder that is faster than WC-860.
There's a statement that this powder is similar to WC-780, but I can't find any information on that powder either.
I know what...

The only testing of this DDT characteristics I've read of is in steel tubes and a cap or booster charge to initiate the event through pressure wave.
There are also events involving several hundred...

I've had good results shooting the 311410 in my AR pushed by just enough 2400 for operation and haven't tried cast in my 450 SOCOM.
The RCBS 180 gr. 35 caliber silhouette sized to .356" is my go to...

Based on the simulation data I just ran, something isn't adding up.
Was the AA #9 a fresh pound that you purchased or something preowned that you traded for?
Long ago there was AA#9-C ( C for...

Thank you for the information.
It's very useful to my use and application.

I have a 280 Ross rifle with a .287-.288" bore.
Woodleigh bullets would have been my choice, but then there was the fire and production halted.
Plan B is to powder coat .284" diameter bullets to...

I've done a couple batches of double coated rifle bullets with OD green processed at 400F for both cycles. After the first cycle the coating looks even, but I'm seeing some coating sag on the double...

After 2 coats the 25 bullet test batch bullets measure .2875".
Now I just need to wait until Wednesday for the dies to arrive.

First batch of 25x 150 gr. jacketed powder coated bullets in the oven.
Used steel BBs in a Thumbler tumbler for 3 minutes to apply OD green.
Placed the bullets on a piece of 1/4" aluminum plate...

The original 22 Lee Bator mold is my go to CB mold for the Hornet and Bee.
Every Hornet I have seems to prefer a different powder, but I noticed that Alliant 300 MP hasn't been mentions and it makes...

I'll get an order heading your way shortly.

One of my bucket list rifles has always been a M1910 in 280 Ross.
Why?? They were innovative on so many fronts when they were designed and produced.
I found and purchased a unmolested beauty the...

Is there someone machining custom diameter 450 sizing dies?
If so, where should I look?

Thanks!

I was finally able to get bullets from my RCBS 416-400 mold lubed, sized, and loaded. Since I wasn't interested in a full house loading, I opted to use IMR 7383 for the powder as it was bulky and I...

I was cleaning out my Uncle's reloading room and came across 20 rounds of Kynoch 9.5 M-S Factory Ammo(aka 9.5mm Mannlicher Schoenauer, 375 Rimless NE) soft point ammo on stripper clips for use with...

Years ago I purchased a case of IMR 7383 for shooting cast bullets, but as it turns out it works quite nice in a 243 with ~70 grain bullets.
The back story is that I was looking for a simple light...

Spent some time casting some 390 gr. bullets from a RCBS 43-370 mold and now it's time to load some ammo for my M71/84 and take it to the range.
I could use H4198, 3031, or RL-7, but I have a huge...

I have a pre-64 M88 in 358 and it's a wonderful rifle to hunt with. The triggers need work and the barrel is so thin it sizzles after a few shots. How many shots do you need to put downrange to put...

I have a 6.5 Grendel CZ527 with a Leupold 2.5-8 mounted on it.
If you can find a set of Burris rings for it, that would be my first choice.
The other "factory" rings are huge, heavy chunks of steel...

I have a 9.3 NOE mold from the 2011 group buy and was wondering if anyone has tried 9.3mm Gator gas checks on bullets cast from this mold.

I've made 350 brass from 338 using a RCBS FL 350 sizing die.
Just pull the decapper/expander assembly, lube the cases and then run them into the die to the shell holder.

That would be incorrect, as I have several factory manufactured Lee HP molds.
