Anyone with experience with above situation? I am using IMR 7828 for my 160 grain, IMR 4831 for my 150 grain, and now want to work up a load for 140 grain bullets. Is Reloader 22 the obvious choice, or are others better? I use Winchester nickel plated brass exclusively. Bullet type would be Ballistic Tip, Accutip, or similar.

That will work too, pyro. I was also wondering if the IMR7828 will work, or whether or not that stuff is better for the heavier weight 7mm's? I'm so tickled about what it does for my 160 grain Partitions.

im trying it in my .264win mag right now im only shooting a 140 there as well, i assume it will work well with the heavier bullets as would h-1000 in the .280 150gr and heavier

My Nosler manual shows a slam dunk for Reloader 22, but I tried it with my 150 grain loads and it didn't work out at all. Of course they were shooting out of a 26" Wiseman test barrel, which embellished the results.

The Scirocco's are even longer, I believe, and could not get in a full load with 150's, without violating OAL. The 160's give you what your hated calibre can't! Gotta go to a fish fry, catch up with you later.

I don't have my manuals handy, but my instincts tell me that all the propellents you mention are all too slow to get optimum velocity out of the 140 grain bullets in a
.280 Remington.
IMR 4350 and IMR 4064 would probably be a couple that might work better, but that's off the top of my head. Reloder 19 also. Check your manuals!

actually ronk with the 150gr and heavier bullets all the powders mojo and i mentioned are in my books, r-22 and imr4831 can give you the best vel. with the 150's and imr7828 and r-19 are about 100fps slower step up to the 170gr and imr 4350 4831 7828 and r-22 give the highest vel.

Ok, I'm not surprised at any of that , but my offhand sense of things is that those powders will bulk up too much of the case capacity before optimum velocity could be achieved with the lighter 140s.
I have not loaded any .280 that I can recall, so I'm probably mistaken.

ive tried about every powder mentioned in this thread except r-22 imr 7828 and h-1000 in the .280 if that 4350 load didnt shoot as good as it does out of a m77mkII i would try those others too.

I'm pretty sure you could get accurate loads with any of those propellents, but I think you will get higher 140gr. bullet velocities from propellents that burn a little faster, if that's important to whatever you may be trying to accomplish .
The slower ones Mojo mentioned are definitely the way to go for the heavy bullets, though.

It looks to me that the Reloader 19, and IMR 4350 might be my best bets, with the IMR 4064 and 4831, along with AA2700 as an outside possibility with those. Ever try any of those ball powders?
Wonder if pyro is up to 3,000fps, with accuracy? Or did you need to back off to tighten up your groups? Thanks.

im not quite at 3000fps but im over 2900fps i use 52gr of imr 4350 i will see if i can get you a picture of a group i shot with this load, btw, r-19 wasnt worth a damn with the 140gr bullets threw them all over the place

You are really doing well if you are getting over 2900 with 52.0 of 4350, especially with a 22 inch barrel? You are not at max load there. Check the tables.

yeah its a 22" barrel, and i know im not at max but that 52gr mark is as accurate as i can get less powder the groups get bigger and more powder does the same thing

Did you attempt to increase cartridge overall length? Don't touch the lands, you must back off which you probably know! It may increase your accuracy and speed too.
