I just came back form the range where I was sighting in my classic deer rifle, a model 8 in 35 Remington. My load is a 212 gr. RN GC at 1970 fps and this load will group under 3" at 100 yards from the old M8. Expansion at 100 yards into water jugs is on the order of 13/16" with 90% weigh retention. I consider this a more than adaquate deer and Black Bear load. This compares favorably with my 220 FPGC load for the Krag. In actual tests the Remington factory 200 gr jacketed slug goes just under 2000 fps from the same rifle and offeres no better expansion or weight retention, but most of the local shooters seem to think that the cast load is lacking something. I sure don't see how or why? I can't help but think that anyone who needs anythng more to drop a deer out to 125 yards is a P!$$ poor hunter. An uncle of mine claimed that the 32-40 was a super deer gun (32 bullet 165 grains at 1500fps).
I think the differenc is that i was trained to only shoot at a vital spot on an animal and never to shoot unless I could hit that vital spot. Years of 22 short and head shots on squirrels insured that the patience to wait for the shot was developed. The bottom line for me is that it matters little what caliber you shoot or how fast the bullet goes, it's where you put the bullet that counts. So this year again i will head to the fields with an antiquated gun (circa 1913) and an anemic load to drop the deer that got away from a nimrod with a 359 Remchester super short manglum.
Good Luck to all the cast bulet hunters!
