Are you defending a house in an urban or suburban setting? Do you have others in your house, do you wish to limit collateral damage?
77 grains is very heavy for .22 centerfires, such weight is usually reserved for long range match ammunition and some hunting rounds when ill advised people refuse to take the better advice of medium game hunters and INSIST that they MUST use their AR 15 to hunt everything because they have a point to prove or some uneducated kid who doesn't know any better.
Are you intending to defend a large yard or farm? Unless you are using the rifle to defend against threats at potentially long range, 77 grain match would be the worst choice possible. Such match ammunition has poor effect on flesh compared to soft points and hollow points actually designed for expansion. In many cases, match hollow points only have a hollow tip as a part of the design, not as the hollow point most people think of for expansion. Such bullets are made for competition or long range precision.
Then let's take the weight issue. I'm of the old, old, old, old school of big weight and energy vs. velocity. But that being said, the .22 centerfires rely on velocity and sheer energy to do its damage, and do fine against thin skinned animals such as human attackers with smaller bullets. The standard weight 55 and 62 grain bullets are explosive at short combat ranges, and do excellent damage. The medium weight bullets have enough weight and sectional density, and they carry plenty of heat, and will do just fine.
And my mocking of the use of .223 for deer hunting carries an important point in collateral damage as well. The small, fast bullets of the .22 centerfires tend to explode on everything, hard and soft, making it a terrible choice for hunting anything bigger than raccoon, with a reputation for bullets exploding against bone and failing to deliver fatal shots. On the other hand, many .223 proponents say this is the best feature of the round for home defense, as the bullets will tend to disintegrate into attacking targets and into nearby obstructions lessening the chance of others being hit by misses and shootthroughs. Again, a big heavy match grade bullet will tend to over penetrate, keeping its integrity through targets and other objects, making it more dangerous to others in the bullets path.
Are you going to face down an attacker trying to run you over with a truck? Maybe that 77 grain match would be a great choice. Trying to shoot a man in your house, in town, with your kids int he next room? 62 and 55 seem to be the choice among those who use that caliber.
