Jerry ... For factory loads try
www.natchezss.com.
The last time I checked with them they had the Rem Green 140 grain PSP for $24.95.. Probably it would be better to order more than one box to help offset the shipping/hazmat fees...
As far as them shipping to NY..I live upstate and I have ordered shotshells by the case and pistol ammo from them through the mail with no problem....
If you live downstate/Weschester Co. it might be different..That's a whole different world down there..
...
Good luck..When you begin reloading, let me know..I can get you started in the right direction as far as powder choices and bullets are concerned..
