While rarely hazardous (when using published data), compressed charges can become another factor with which to contend, on the road to getting a good, consistent load.
SOMETIMES, a bit of load compression will tighten groups (most often when done with great uniformity), while in other cases, compression will increase group size. Each rifle is something of an "individual response", when loading for it. Don't let this discourage you, but bear it in mind, if things you try do not seem to work as well as you hope.
There is also the matter of propellant utility. If you intend to reload only for .22 Hornet and have no plans to do so for other cartridges, well and good. If you contemplate reloading for other calibers in the future, it will not hurt your budget to use a propellant that works well in those, also. H110/W296 and IMR-4227 are "velocity champs" for the original magnum revolver rounds, so if you buy one of these and wish to reload for it, you need not go in search of a different propellant. H4198, while not useful for the original magnum revolver rounds, is remarkably versatile in small to medium-capacity rifle rounds, ranging from your .22 Hornet, to the voluminous .45-70 Springfield.
These are factors and considerations that might save you some serious money (with propellants above $45/lb. in many place), down the road. Having a good idea of your reloading plans beyond the .22 Hornet (if any) can be very cost-beneficial. I wish you EVERY success in reloading your .22 Hornet, but I suspect that you may wish to "branch out" at some point. Moving to another caliber and having many of the desired components already on hand can greatly simplify your life.
