I have just put togheter a 44 magnum ammo.

7 grain of W244, Starline brass, Cactus lead bullet 200 grain and S&B large pistol primer.

The bullet was seated at 1.570, but when crimping, it went down to 1.560.

SInce therre is a 0.010 inches short, should i disasemble those bullets?

Will they be safe or dangerous to shoot with my 629-6 and my Big Boy riffle?
 
Your crimp grove is tapered and pulled the bullet down in the case. Freaked me out the first time, but it's by design. No issue at all unless your at max for that oal.
Max load for W244 for 200 gr lrnf is 7.3 grains. I am at 7 grains.

Last time, i loaded at the bottom 6.2 grain and there was sooth on the side of the case.

Send it. Long as you're crimped into the crimp groove, and they are not too long to function in the action, or so short, and your load was on the ragged edge of hot. With straightwall rimmed cartridges the length is really a suggestion, as long as you are using an appropriate bullet, with a correctly located crimp groove, a hundreths of an inch is not worth the worry.
 
You should be OK. I strive to end up with the end of the crimped brass to land in the center of the crimp groove. That is the spot that the bullet maker designed it to end up. Not every bullet has a crimp groove in a spot to end up with a OAL to end up the same as loading data shows. This is one of the times when things such as OAL are a guide ofwhere you need it as opposed to an exact location.
Should you get into autoloading ammo your OAL will be to fit in the magazine first and probably shorter as derermined by the plunk test.

All loading data is a guide to making safe data. I will consult several current manuals and develop my own length, propellant charge, and crimp while staying within all data presented.
 
If you look in the old manuals there is no oal listed.... when things are listed currently they only represent the oal tested, not nessisarily the one you need. The only real warning is max loads are made from the listed oal, so if your shorter, max is lower than listed.

What about pressure? For this load, 7 grains of W244, will be max 16 600 psi for 200 lead round nose. But, since the oal is shorter, as per other user had written here, pressure will be negligible?

I have no idea where you got 7 but that seems over a grain heavy Screenshot_20230803_095615_Chrome.jpg
 
I've consulted 3 sources: Hodgdon reloading manual 2020, Hodgdon website and Lee book 2019 revised.

As long as your comfortable. I don't use Lee as a reference because they don't test... I'm used to seeing differences between manuals, but that much of a change from the same publisher is unexpected.
