| I have been reloading for 20 plus years but i have never used Accurate Arms Powder ,but had to get some yesterday as ,well if i didnt i dont reload,so i got a pound of AA2495 to load up some 165 sst hornady rounds for the 308,but just very confused as sierra says for a 165 to start at 37.0 and stop at 40.4 and AA says start at 40 and end at 44 grains,may be a bit off as everything is on the bench,but why the big swing in the loads ??? I am not really sure about this powder at all now,so if any of you are using this powder a few answers would be great,Sure wish IMR would get some powder on market as i still like the old stand by 4895,4064,3031 or RE15 |

Hornady #7 shows-
start load: 33.1 grains for 2100 fps max load: 40.7 grains for 2500 fps That makes two votes for the lower range of published charge weights. This gun powder is in the same range of burning speeds as the 4895's, and close to AA2230 (slower) and H335 (faster). If someone with Quickload sees this, I would be interested to see the results of an analysis with 43 or 44 grains of AA2495. |
So 40 grains is compressed with a 165 grn bullet set to 2.750 COL

A compressed load is not necessarily dangerous. A gunpowder that is slow for the bullet weight will permit more powder in the case to the point of overfilling the case and produce low pressures. In this case, AA2495 appears to be a bulky powder that fills the case well before the maximum pressure can be reached. A compressed load can cause a bullet to come unseated if the neck tension is too low.
MoneyMaker - Fill the case slowly with a long drop tube if you have one, or swirl the powder into the case through a funnel. Then pick the case up and tap the rim on the bench to settle the charge, then top it off with one more session of taps, and finally measure the charge weight. I'm curious. |
| 40 grains was in the neck above the shoulder,just alot of powder as i understand it is a course long grain stick powder but when i used Varget it was not like that as far as i can remember,think i will load up a few starting on the low sierra load side and see what takes place,just gonna have to find some other powders i like and have used alot of like,IMR 4064,IMR 3031,IMR4895,H4895,RE15 if i can locate about 2-3 pounds i will be good for a year,also still want to go get 1k of large rifle and 1k of large pistol primers so i am set for about 2 years of deer loads and casual target shooting.May be getting a 243 win rifle to use as deer rifle here soon,unless they have a tikka or savage 308 in stock. |
