Sorry Kirk, been out at the cabin for a while. I believe that you'll find solid bullets tend to create more pressure so I'd use the low end of AA#7 for 45gn. Sierra spt. and work from there. You may want to pick up some moly spray and coat the contact area of the bullet to help reduce pressure. I'd also start with a small pistol instead of the small rifle primer. That may be unnecessary but better safe than sorry.
It would depend on the ogive and how similar they are.
I guess I'm not that worried about bullet length for the 5.7. You should have a decent set of calipers or a digital micrometer where you can measure that. One word of warning, the NTX Hornaday bullets in 35gn. will push pressures up past 35gn V-Max . It's a different design with a boat tail that seems to really affect pressure!
Yes Fiocchi, I think they are starting to use Speer bullets in addition to Hornaday. I can't justify paying nearly $70 for 50 Gold dots.
I still have some of "law enforcement" red box Fiocchi for self defense but now that hunting season is over I have several other bullets to play with.
There are actual reloading guidelines from powder companies as well as vetted reloading articles. Yes, this is not a round that should be loaded by a new person or someone who doesn't understand ladder charges and pressure signs. That being said as long as the correct caliber bullet is loaded bore friction is not a problem IF the proper precautions are taken. I've personally reloaded and fired over a thousand rounds of this caliber with different bullets. There are limitations as to bullet weight and charges and the 5.7x28mm case requires special care and vigilant inspection but the current cost and availability of ammunition makes it worthwhile.
While I don't put a lot of stock in some YouTube videos, Paul Harrell is an accomplished world champion shooter and former Leo shooting instructor. He has an interesting video where he shoots 80 gn 9 mm Ft Scott ammo through a meat target with both level llA and lllA body armor strapped to the front.
As I stated before, this isn't for everybody. I have a load that I've worked up for 43gn. monolithic solid Maker bullets. Because they have a different profile that doesn't make the info interchangeable with Ft. Scott 40gn. Even though there is powder company info. for 35gn. V-Max bullets it's pretty much useless for 35gn. NTX bullets made by Hornaday. (Fiocchi is now selling the NTX bullet in ammo). This can be true for any caliber. You are taking a risk whenever you substitute bullets even though some powder manufacturers will say it's ok to do that.
That makes sense, in my experience any time your dealing with soft point lead tips you're going to get variance. Those numbers aren't bad.Someone over at Midway put a micrometer on the Sierra 45 gr. SPT. He measured a set of 5 and came up with: ".626, .625, .624, .627, and .625" ...so an averate of .625

There's the rub, do you want violent expansion with a rapid energy dump, or something with more penetration. I think we can agree that the lighter the bullet, the quicker the energy will drop. Fiocchi had the near perfect balance with their 27gn hollow point with penetrator green tip bullet. That bullet didn't expand at all , would penetrate level lllA armor, then tumble. And it DID tumble creating a pretty massive wound channel for such a small bullet. It did not over penetrate though. That's been my guiding objective to come as close to that round as possible. It travelled at right around 2000fps. I've been reluctant to push the speed on these since I'm using used brass. I've seen some concerning pressure signs so I'm just playing safe for now until the day I can either get more of the red box green tips or virgin brass. I have some 32gn. Maker monolithic expanding (according to them) bullets that I'm going to try next. I also have 500 Dogtown 34gn hollow points that I've used before. They're actually pretty good on varmints. I've shot a few porcupine and one coyote with them.
They actually make three different bullets in this weight, expanding, fracturing, and tipped. I picked up the expanding version. 1in 7 to 1 in 9 recommended twist.
The 40gn Hornet and the 45gn FN I load for my TCM along with the 33 Hornet and the RIA 40gn.
YEOW
, I'm sorry man that's a new one on me. If you called him right away and he told you that then it's BS. He should of been able to change the shipping. I would of told him I was disputing the charges on my credit card! If he wants to stay in business he better figure out how to at least warn people on his website! I'm going to write him and tell him so!
I've never tried graphite, When I worked in a Brass plant they used graphite in the cast shop and it was really nasty stuff. It might of been totally different then what you're talking about using so maybe someone that's used it before can chime in.
I stopped using FedEx cause they screwed several shipments up on me. Now UPS? That sucks! If you're going to buy or sell a gun out of state Bud's gun shop has a service called Ship your gun that was very reasonable when sold a gun to a guy in Arizona from New York. They even insure it and will send you proper shipping materials if you don't have 'em. That being said, I don't know what carrier they're using so that may be a problem now too.
