[QUOTE="backwoods83, post: 644266, member: 29890"] Easy answer, the heavier the bullet the more it effect it has on velocity in shorter barrels. A common load for the 210vld is 73-77grns of H1000 depending on seating depth, with fed 210 or 215m or cci 250 primers in norma brass in a 28" 10 twist barrel for a MV of about 2950fps, this combo doesn't typically work well in a 24" barrel because that high of a powder charge of that powder will not get a clean full burn before the bullet exits the muzzle, so you in turn step back to a lower charge of a faster powder like H4831sc, then you will be extremely hard on cases to break 2800fps. 26" is a happy median so to speak.
