IMR 7828ssc in .243

[Dgd6mm]

I am looking for shooters that are shooting IMR 7828ssc in there .243 with 105 grain bullets. I just replaced one of my 6mm Competition Match barrels with a .243. I have a decent load with H1000 but considering trying the 7828ssc. Any information even if it is an AI, SLR, or another variant would be appreciated.

Thanks
Don Dunlap

Don, Retumbo with a fed 215 is awesome in the 243 win with a 105! I can't say on the 7828, sorry.

Quickload shows 46.5 gr of IMR-7828/7828ssc is "about" MAX (60,000psi+/-) with 105's in the 243w.

Hodgdon's reloading data claims 44gr as max.

So far, Quickload has not steered me wrong.

Sorry I don't have real world data and if my post is not useful I'm sorry.

Thanks Ackleyman, I have ran Retumbo in several .243's and 105 amax's, it is good.

Zero, I ran it in QL changing the H2o capacity of my brass, bullet length, case length and it works out good for this 28" X-Caliber barrel.

I am just hoping to get some experience users to give me a thumbs up that it works for them.

Thanks,
Don Dunlap

Hey Don,

I run it my SLRs with nice results. Running mid 44grains with 108s around 3125w 28" and 3060 w26"....coated bullets....so work up.

Good luck!

I don't know if this helps you any . I did this years ago for my son , in a 243 for hunting . I used IMR7828 with a 100 gr partition . this was before the short cut was available . it shot well . the only problem I had was the highly compressed powder charge would push the bullet back out . I had to reseat the bullets the next day . I think the ssc ( short cut ) will solve this problem . if I were to start to load for that rifle again I'd sure give IMR7828ssc the first try . Jim
