In the early days we used cream of wheat, cornmeal or kapok as a filler to hold the powder charge in a uniform shape and uniform relationship to the primer, later we progressed to Dacron. Mostly the charge is spread out thinly across the bottom of the case so that the primer flash hits a different surface area of the powder and at different angles from shot to shot, causing variations in ignition that play havoc with ballistic uniformity. Consequently, this leaves a lot of empty space, allowing the powder to assume varying positions in the case and varying shapes from shot to shot. The small charges of very fast pistol or shotgun powders traditionally used for reduced loads normally weigh from 6 grains in a standard case to 25 grains in a magnum. Trail Boss represents a major breakthrough in assembling reduced loads because it does away with the necessity for using a filler between the reduced powder charge and the base of the bullet. Start them off with light loads until they develop confidence and familiarity with the rifle, before easing them into full-power hunting ammo. They provide a handy method of accustoming a youngster or a novice shooter to heavier recoil, without developing a serious flinch. Reduced loads are great for informal target shooting and plinking since they have light recoil and muzzle blast. Also, a small charge of a fast-burning powder can produce high pressure, even in a large-capacity case if warnings about maximum charges are ignored. Jacketed bullets being harder and less malleable produce more pressure, and, usually lower velocities. Also, the smart handloader has to exercise some caution when substituting jacketed bullets for leaden ones at maximum levels. It is only rarely that the rifleman shooting a bottleneck rimless cartridge or a belted magnum may want to drive a jacketed bullet at 1000 to 2000 fps to serve some special purpose such as taking small fur bearing animals without ruining their pelts.Ī major problem that plagues this practice has always been the small charges of fast burning powders necessary to produce these lower velocities. They seem to require a fair degree of knowhow, in addition to technical expertise, that is not possessed by the average handloader. It’s not so cut and dried, however, with cast bullets. Anyone can pick a jacketed-bullet load out of a manual, follow the recipe, and end up with a reload that will deliver at least acceptable results in his rifle or handgun. Loading cast bullets has always been a sort of post graduate exercise in the art of reloading since there’s a number of pitfalls involved which can trap the unwary. ![]() ![]() But riflemen too, can benefit tremendously from using Trail Boss which offers superb versatility in bottleneck cartridges with reduced loads with lead and jacketed bullets. Hello im interested on how you got on with these and also if you wouldnt mind a little clarification, did you use any type of filler to keep the powder close to the primer or drill the flash hole? and did you seat the bullet to the lands or standard seating depth, or was everything standard like in any other bullet.ADI has produced a unique advance in propellant technology with Trail Boss, a specialist powder designed primarily for reduced loads using lead bullets in pistol cartridges. ![]() MV 1082 fps(the low skewed results, without it Ave 1096, SD 28) High 1047 fps low 821 fps Accuracy about 1.5" at 100 yardsĪve.
