Hodgdon's Reloading Data Center

[QUOTE='Boo]$9.99 + taxes.

The manual doesn't have anywhere as near as many loads as the web site. The article on IMR Trail Boss and it's use as a cast bullet load for rifles however is well worth the 10 bucks. :)[/QUOTE]
Thanks!
 
More powder?

I sent them a thank you. They never had any data for the 52gr .223 though but that's OK. I will probably move up in bullet weight and not down. This is kind of off topic but...why is it the lighter bullets use more powder than the heavier ones?

It is because the lighter bullet doesn't create as much pressure getting out the barrel, as compared to a heavier bullet. So, to get the pressure, and the velocity, up to standard levels, more powder is required with a lighter bullet.
 
Thanks 'Boo!

I took a quick peek and it's like the new manuals, they err on the conservative side. This of course is to be expected. So we know that in most cases a fellow can go past their max loads a wee bit and still be well within safe territory. Work loads up carefully watch for pressure signs do this for your own gun all the usual blah-blah-blah. :rolleyes:

GREAT resource, and already bookmarked in Favourites!

Less inertial confinement (they move out of the way more easily because they weigh less) = lower pressure for a given powder load. So more powder to bring up the pressure. And there's more space in the case, so where that is the limited factor you can stuff more in.

I said that in fewer words.

Reloading and ratio of powder to bullet weight

Can you spell inertia?

A lighter bullet starts up faster than a heavy bullet, thus more powdser can be put under it.

Conversely, a heavy bullet, moves out slower, pressure goes up until bullet moves up barrel. Check any loading books and the lighter bullets loaded to max with powder "x" will always show a larger charge of "X" than the heaviest bullets. And check the muzzle velocity, which will be higher for the lighter bullet.

As you putting me on with this question? Really!

Back up a bit.

I have seen this post quoted at least 4 times in this thread. Some have answered with scoffing answers, others with actual information. Although I ma new to htis forum, I have been playing with these topics for a number of years and I have discovered this...none of us have all the answers, and few of us have the correct ones.
What is a discussion forum for? To discuss, exchange information and ideas, perhaps even, to educate. That's what this member was looking for. A question to fill in the gap in his knowledge. Perhaps his experience isn't as deep, perhaps, that question was answered years ago and he missed it.

Answers like, "because it can, or I can't believe you are actually asking this" (paraphrasing since I don't know how to keep adding quotes yet) don't help the corporate knowledge and can keep people from asking IMPORTANT questions down the road.

Let's try to remember that we have not all doing this for the last 30 years. Real questions deserve real answers, preferably based on real knowledge.

That's my $.02.
 
Wsf ??

I worked through the Hodgdson site for 9mm & 147 gr FMJ. It lists a powder called WSF. Is there another name/number for this powder. Was unable to locate it on the Winchester site.
