My supplier has just sent me some 40gr. cast bullets for my .22 Hornet. Apart from playing with some low loads of Red Dot I have been loading 7.5gr. Lilgun quite successfully. He included a few 50 and 55 gr for me to try but I can find no published data for these weights. Considering the low pressure properties of Lilgun I presume it will be safe to use a similar load for testing.

Am I correct in this assumption ? It's a CZ527 bolt action rifle with a 1-16 twist.

When loading jacketed 40gr V-Max bullets I use 12.2gr Lilgun for a muzzle velocity of over 2,500 fps.
