OGoat, I have the same problem and there are two more possibilities for you. You can haunt Ebay for the obsolete Remington 100 grain RN and you can still buy the 87 grain Rem. 25 cals intended for the the .25-20.
But if you get any swagers offering 100 grain FN .25 cal suitable for deer, let me know, please.
Please.
PLEASE!!!!!!!!!!!!!!!!!!
