I have not worked with the 6.5JDJ (or the #2) but have used quite a few different light 6.5mm bullets. The 85gr Sierra and 90gr Speer TNT have a high splatter factor on smaller varmints. If you are after fur I would go a little heavier. The 100gr Sierra and Hornady's are VERY accurate in my 6.5T/CU with 100yd groups typically near 1/2". The 100gr Nosler BT's never did shoot well for me at all.
