Veral,
A number of years ago I had a Winchester '95 rebored to a 35 Whelen. My idea at the time was to have an affordable rifle and ammo somewhat equal the .405 Win., in velocity and bullet weight anyway. Remember at that time the .405 was a forgotten household word. I had it rifled to a 1:12 twist basically to stabalize a jacketed 300 gr bullet. I never did fire those 300 grainers and basically stuck with jacketed 250's. In my readings over the years, the basic consensus is to use a slower twist when using cast, in this case 1;14 or better yet (better?) a 1:16. It is was said that a faster twist would strip the bullet. My definition of that would be, that it would not grip the rifling and skid a ways, until, it grabbed, unless of course you would slow it down to alleviate this from happening.
A while back you cut me what you termed a Modified LCFN for my .416 Rigby, a LCFN with the metplat diameter the same as a LFN. This bullet style is what I envision for this .35 Whelen. I would also like it to be as close to 250 grains as possible, for no other reason, that is what I vision to be right for my rifle and the game I intend to, hunt. Can I expect to get Whelen velocities with the 1:12 twist?, or will I have a duplicate of a .35 Winchester?, (which isnt all that bad either). Also, what has you experimentation's concluded to, as results from shooting cast bullets in different twist rates?
If you already have'nt figued it out, I am looking for the difinitive answer to what "has" been written on this subject of to fast versus to slow of twist for a cast bullet. Thank You CRASH87
