The factory stock on my Brno was very light, and the rifle came in at about 7 pounds with it. The McMillan increased the weight to 9 pounds, but made shooting with irons more difficult due to the higher comb.
The push feed vs CRF debate runs out of steam if your specific rifle feeds reliably. Folks who like Remingtons tend to claim that the extractor is pefectly acceptable, and I agree to a point. Thousands of rounds can be cycled with the Remington extractor, but they do have a life expectancy, and I've had to replace several, but then again I've owned more Remingtons than any other push feed rifle.
I do not accept that location has a bearing on the type of action selected. To my way of thinking, when a round is fired at game, a follow up round is chambered immediately after the shot while the rifle is at the shoulder, and this is done regardless of what game is the target. The rifle will cycle or it won't. If the rifle cycles all is well, if it doesn't you have a problem. If you have a problem, that problem needs to be addressed prior to taking the rifle afield.
There are advantages in the purchase of both factory and custom rifles. The factory rifle can be brought home and shot on the same day. The custom rifle can take months or even years to complete, and the cost can be intimidating. During the various .375 Ruger threads I was asked if I had to do it again would I go with my custom Brno or a factory Ruger Alaskan. The performance of both rifles is very good, but today I could order the Alaskan and have it in a few short weeks, where as the Brno took me 3 years to finish and 4 times as much money to pay for.
