Does anyone have any information on ballistics, accuracy, and ease of loading hawk 190 gr. bullets for a .30-30. Will be shot out of a Glenfield Model 30A.

No real world information. If I make estimates of the bullet length of about 1.1 to 1.2 inches (depends whose design I start with), QuickLOAD thinks IMR 3031 might get it to about 2000-2050 fps from a 22" tube, depending on capacity assumptions I make, using about 9% less powder than a 170 grain Sierra FP does to reach the same peak pressure (because of the greater mass and lower powder space). But you'd have to work loads up yourself to really know. G1 BC (the usual one published) will be around 0.210 to 2.25 (again depends whose design you start with) if you want to run ballistics tables from those estimates. The JBM site has free ones to use.
