Okay, looked in his book On Your Own in the Wilderness (1958) on page 52. In addition to the cartridges in the rifles, he recommends two or three in the pockets, 15 big-game cartridges and 5 small-game cartridges in the rucksack. Grouse-loads can be found in his other books Wildcraft and Mister Rifleman. The reason why he recommends so many is: one can shoot meat for the pot or for their pelt. Or in an emergency, a volley of fire can used as distress signals.
Watch, compass and waterproof matches should always be in the pockets of the pants on the person. So I am assuming this is "worn weight".
For butchering large animals like a moose, he recommends hacking with an axe or cutting with a folding saw or hacksaw. For medium-sized games like deer, a skinning knife and a whetstone is all that is required. These should be stowed in the pack.
Packs for one-day hunts should never exceed 10-lbs, and overnight stays or week-long trips should never exceed 15-lbs (page 50). For still-hunting or hunting close to civilization, pack should not weigh more than 10 lbs (page 51-52), and for wilderness hunting (eg. northern British Columbia), 15 lbs.
There is a mention about cameras, but nothing about how much it should weigh. He just says many sportsmen like to take pictures of their trophy. He did say this is optional, and it should only be carried in the backpack.
As for clothes (page 53), down insulated jacket, and mittens specially designed for shooting in cold-weather. Mackinaw recommended by earlier woodsmen like Kephart are not necessary as they are outdated and bulky to wear while walking through the woods. But those are not required of people who live in warmer climates.
This section intrigues me because there's a lot of people out there in the bushcraft community who think down-filled jackets are inferior to mackinaw.
The only extra garment that should be carried by everyone is a woolen shirt if the weather should unexpectedly becomes chilly.
For protection against rain, poncho. Ironically, he also recommends wearing it as a vapor barrier liner in cold weather too. He didn't actually use the term, but he conveyed the concept.
For sleeping, he says a down-filled mummy sleeping bag are lighter, warmer and more compact than woolen blankets of old. One can even supplement the sleeping bag with fire if needed.
For binoculars, he just wears it around his neck; probably why the weight was never included.
For grubs (page 54), rolled oats, cornmeal, egg powder and milk powder is all that is required to sustain a person. Sugar, salt, bacon, tea, chocolate and dried fruits will add variety; and it is recommended to experiment at home. For a hunting trip, he recommends bringing enough for seven meals. He made a slight remark about people carrying too much food. I am assuming he is making another jab at Horace and Nessmuk who like to bring luxuries on them. Wouldn't be surprised as he makes lots of remarks about how woodsmen of earlier decades were doing things wrong.
For cooking, he recommends an old fruit-juice can with a wire bail attached. Those who want a frying pan should use an Army mess-kit, not a pan from home. He recommends bringing only a spoon as one already has his hunting knife and a fork can be replaced with a stick.
In addition to all this, he also recommends bringing a plastic bag about 15 in2 for carrying back offals home.
Shelter is not discussed, but he does go into great length elsewhere several times. His favourite is making a tarp out of plastic or parachuter's nylon.
The hunter's pack should not weigh more than 15 lbs for all the above, including consumables.
