4764fps 17gr gsc sp solid nearly full to the base of the neck with xx.xgr h4198, cci br400, remington 17 fireball brass, remington svs 26 inch 1 in 9 twist.
That is a case nearly full of h4198 up to the bottom of the neck. Don't use a 20gr std bullet to use with the same powder load, it is unsafe with any other bullet. The gsc 17gr sp solids are drive band bullets allowing about 0.5 gr more powder in the 17 REMINGTON FIREBALL.

Read what Kenny wrote below first, then consider the safety margins you SHOULD follow for safe practices and loads.

Don't use the above load if you dont have a 17gr GSC drive band bullet.

Drive band bullets ARE NOT THE SAME AS GROOVED BULLETS.

http://www.gsgroup.co.za/faqdrivebands.html

" GS Custom HV, FN and SP bullets are manufactured so that the shaft fits the bore diameter of the barrel (A). A series of driving bands are machined to fit the groove diameter (B) of the barrel. The bullet shaft rides on the lands of the rifling (green sections) and the ogive and boattail are not engraved. Although the shaft touches the barrel, material is not displaced from the shaft of the bullet. The thin drive bands on the shaft simply deform (red sections) into the spaces behind them and the resistance to engraving is the lightest of all bullet designs. "
