For off hand/unsupported shooting it is best to have the balance point as far forward as possible.
I disagree, as do the majority of successful offhand specialists.
A rifle whose muzzle is that heavy SEEMS like a good idea. Indeed, all that inertia out front can slow the vibrations of a really hard holder (like...indoors).
The trouble is twofold.
First, most of us don't shoot in an ideal offhand condition every day. Bad wind and firing position issues can both require the shooter to literally DRIVE the muzzle to the middle of target, and the shooter breaks the shot at that brief moment with a good sight picture (not great...just good).
When you are trying to drive the rifle, an overly heavy muzzle (or just a 17 lb rifle in general) is extremely hard to control. That very inertia I was just talking about is now moving against you, and requires a lot more effort to slow it down and reverse direction.
The other problem is in grip and position. UNLESS you have a butthook, too much weight toward thd muzzle requires a lot of grip and downward pull on the pistol grip to keep the muzzle up. This leads to poor position consistency, and the gripping reduces finger sensitivity, while INCREASING tendon friction in your hand...more tension = larger sympathetic motion when you yank that bang switch.
Short version: keep the muzzle weight down if you mean to shoot offhand without a hooked plate. If you want to have a truck axle out front, then weight the rear.
...or just get okay with mostly hating offhand.
