2013年4月21日 · There are no currently suggested loads using IMR 7828 in .30-30, .308. There are only four listed for .30-06 using 190 - 220 grain bullets. By the way, mostly for newbies, If it isn't the newer "super cut" for easier measuring, be careful. Meter a partial load and bring it up to weight using a scale and a powder trickler.

2006年1月25日 · I have found that my current tins of IMR 7828 which were purchased between 1986 and 1990, seem a tad faster burning than data from some other users. I have found that Re 22, IMR 7828, Viht N560, Viht N165, Win WXR, AR 2213sc(H4831sc), and the long discontinued W785 all seem to produce Max pressure with load variation of 0.5 to 1.0 grains.

2020年6月29日 · Here's my deal. 80+ grains makes short work of a pound of powder. I shoot the really good powders for the rifles I shoot the most, 25-06, 270, 280 AI and 7 mag. I won't shoot the 300 Wby that much other than load development and hunting. Under 50-60 times per year. I have 5 lbs of 7828 ssc just sitting in the coffers looking for a reason to he ...

2018年2月16日 · Hello gang. I'm new here so hello to all and thanks in advance for your help. I started loading years ago based on Layne Simpson's recommendation of 80 grains of IMR 7828 behind a 160 grain TSX. I fired 40-50 rounds with no problem. Rifle is an accumark with 26 inch Barrel.Fast forward a few years and everyone is saying that 77 grains is max.

2005年1月28日 · I burned more IMR powder than any other brand and never experienced any. I'm from California and the temperature here varies from the 40's in winter and 100's in the summer. I used 7828 for my 300 Win Mag, 4831 for my 280 Remington, 4350 for my 338 Win Mag, 6MM Remington and 243 Winchester, 4064 for the 308 on some loads, 4895 on my 3030, 3031 ...

2004年4月3日 · Shooting 80gr Berger VLDs out of my 22-250AI 26" 5R 8"twist BBL 42.5 grs of Re #22 produces 3350 AVG 42.5 IMR 7828 produces 3325 AVG both about the same accuracy. 1 more gr of either powder will lock the bolt up.... So which powder should I use?

2021年1月31日 · I'm sure it would work for those weights, but likely a better with 150's since it is a slowish powder. I considered it a few years ago but went down the classic H4831SC route first. They are very similar with IMR 7828SSC being slightly slower burning and a little more temperature sensitive.

2023年2月10日 · IMR 7828 worked well, in my 7 mm Rem Mag. with 154 grain Hornady's ( good Velocity and accuracy ). After selling that Rifle,.. I tried the last couple of, Pounds, in my New ( bought in 2017 ) Tikka T-3, in .270 WSM with, 140 gr. Berger Classic Hunters and am getting 3,185 FPS with, 1.5 inch, 200 yard, 5 shot, groups ( 5/8th's to 3/4 MOA ) and ...

2019年12月8日 · 7828 any, more than not, is too slow, for a 90 grain in 6mm Creedmoor. I run H4831SC with 110SMK, in a 26" barrel @3200 AVG FPS and that's a mid-charge in this rifle, that gives a lot of reloading's with Starline LRP case and tight primer pockets.
