Primers & powder ship ground freight to the 1st 48 states. General Info: Attention! Primer/powder orders ship separately and may arrive at a later date. *See loading data for this powder at and in the Hodgdon Loading Guide located in our Load Data section. With small, easy metering granules, competitors will love how it flows through progressive presses. Additionally, it performs superbly in the 204 Ruger and with light match bullets in 308 Winchester. As such, it is ideally suited for benchrest and small varmint cartridges like the 6mm PPC, 22 PPC, 6mm BR, 223 Rem. Almost 40 years using this technique it has yet to do me wrong.Hodgdon Benchmark Extreme Rifle Powder (1 lb.)Īs the name implies, this Extreme Extruded propellant was developed for precision cartridges. I've been reloading now for some 30 + years and have found that by shooting multiple rounds of the same load and figuring your standard deviation rate for each load, your more apt to get good solid information on your loading to determine which is functioning the best out of your weapon.Īfter the best powder weight has been determined for the reload the next step would be the minor adjusting of the seating depths for off the lands contact to tweak it a bit more. or something that the shooter did by an improper cheek weld, or improper trigger squeeze, etc. If you can pattern a good group with a load you need not worry about was that a flier from the load. I normally load anywhere from 5-10 rounds of each powder weight to eliminate that sort of false read. Barrel temperatures, barrel fowling, load inconsistency, (IE: minor seating differences, case trim lengths, between individual rounds, etc.) can produce an unrealistic / untrue read of the load. The simple reason being minor variances that can contribute to a false read of the load. I'm going to have to disagree with your comment regarding only loading 1 round of each powder charge. If you pick a load outside of the "flat" part of the curve this will lead to vertical stringing at longer distances - small variations of powder charge lead to large variations of velocity and therefore bullet "drop". small variations of powder charge lead to only small variation of velocity. Now you can experiment in and around the "sweet spot" and if you can pick a load near the center of the "flat" part of the curve - this will give you more invariance to the actual powder charge if you don't weigh each powder charge. velocity curve than I would try a faster powder with that bullet/gun combination for economy's sake. If your "group" corresponds to the rising slope part of the charge vs. velocity curve then you have something you can really work with - the powder/bullet/gun combination is a good one. If your nice "group" corresponds with the flat part of your charge vs. If you make a graph you will notice a curve that flattens out as you go up in powder charge. If you have a chronograph you may also find a spot where you get diminishing returns in the amount of powder you use vs. Somewhere in the process you will hopefully find a series of shots that make a nice group - and you have found the sweet spot for that combination of bullet/powder/gun. Take your time and let the barrel cool a consistent amount of time between each shot. Watch each round for pressure signs, and STOP if you see signs of pressure or difficult extraction. Loading 10 or 20 rounds of the same thing to find a load is a waste of time, gas, and bullets, IMO. Honestly, I would load up 15-20 rounds from "start" to "max" in equal increments (one round of each powder charge, and keep detailed notes of which round is which - load two rounds of the starting load, and use one of them as a "fowling" shot into the berm) then run them one at a time over a chronograph - if you have one - from lightest to heaviest load.
