RE: Brush Guns
Brush Gun as defined as a light fast handling gun. Concider any short action bolt with a 21 " or shorter barrel. For this the 308win, 338fed, and 358win would all be tops. Also the lever actions guns would be top rate as well. The the BLR and marlins 336. The already mention is offered in the BLR, and 35rem, 444marlin, and 45-70 are hard hitting cartridges for the 336. A 1-4 or 1.5-5 power scoped would be perfect for a brush gun. Where shots of only 10-15 yards are quite common.
I use the 270win 35rem, 358win, and 35whelen all for deer and up close the 35's areextreamly effective with top ranges of 150 to 250 yards and all damage less meat than the 270win. Its do to theit medium velocities that range from 2100 to 2700 fps and they make big holes. With deer size game the differance of the 35 cals is not that dramatic but starting with plus 300lbs to 1500lbs game the increase in their effectiveness it is very aparent.
