bit confused now..

Bottle says Accurate Powders #7

label says Explosia, Lovex D-036 Selling as #7


Accurate Powders website says

Owkay, that's clear..

So off we go to www. explosia.cz

caliber/powder matrix
D-036 , ok for .45 ACP
#7 is supposed the slower burning of the handgun powder they have


for 230 bullet

grams------grains------m/sec--------- fps
recommended
0.390 ------6.0 ---------230 ------------754
Maximum
0.470 ------7.3 ---------260------------ 853

Owkay, that all kinda makes sense.
Except , i only have 195 grain copper plated semi wadcutters instead of FMJ 230 ball.
and they don't list nothing else.

So i'm kind of confused now as to what would be the safe load
dude at the store showed me the Accurate Powders load page.
But it's not AA#7 at all, it's Lovex D-036-07 as far as i can tell.

That listed 9.5 GRain for 230 grain FMJ, that's a chitload more then the lovex the D-036 load instructions.. So my gut feeling says, bad idea. He obviously didn't read the warning on AA's website, or bothered to check the paper label on the bottle.


So if i use the Lovex data as the reliable source.

And if i understand correctly lighter bullets=
lower chamber pressure & higher velocity..

I suppose i should be able to load with 6.5 grain of powder and still be well in the safe zone to start with..I also read that .45 acp is sort of a round with bigger tolerances in terms of pressure, because of the wide case... That's it's not like 10mm auto where the line between safe load/pressure vs over pressure is very, very thin?

Does that make sense? or should i research it some more?

other then starting off gently if i fire these trial loads @ the range.. Slow, shot per shot, making sure nothing jams or get's stuck in my barrel...
Anything else i should take into account as far as powder charge goes?
Does it matter that the bullets are copper plated, not FMJ ?

Stijn,
I don't know how Explosia is, but American powder companies have knowledgeable test experts on site to help the handloader. It would be worth your time to give Explosia a call or drop them an email. This could be a problem if they only speak Czechoslovakian, but since their guide is in English, you may get lucky.

The Reloading Bench portion of the 1911 forum has many members more qualified than me that also may be able to help you. http://forums.1911forum.com/forumdisplay.php?f=58

It looks like you have a good understanding of pressure and velocity, but the rule of thumb I've always heard was to begin 10% lower than the recommended load and then work up. Better to be safe than sorry. Some people like shooting hot loads, but I have always enjoyed light loads so would start light and work my way up. Do you have a chronograph? It will be a useful tool for accurately measuring the velocity of your rounds.

Also, I've been using Dillon equipment for 20 years and they have the most outstanding customer support service I've ever had the pleasure of working with. I've called a few times to ask for help and it has always been a positive experience -- the last time they sent me some new parts for free.
Be Safe,
Dennis

from what i read on several forums Explosia is not good at providing information.
Think i'll just make some calls and see about getting me powder from a decent supplier, decent brand, decent load data for that brand/type..


I ain't risking my hands, my eyes or my gun over 35 bucks worth of Czech powder.
