I need help with reloading a 280 Remington with 19 in barrel

MO Whitetails · 2026-02-02T15:00:37-0800

I have reloaded for 40 years, .243,35 Rem, 7 RM. A friend wants me to reload some brass he was given for his 280 Remington. Rifle is a 1995 Browning X Bolt II LH Stalker, 22 inch OEM barrel has been shortened to 19 inches. 10 inch twist. He shoots Whitetail deer mostly, but an elk now and then. My thoughts are a faster powder and lighter bullet than the 160 ABs w/66 grains H4831sc that I shoot in my 7RM. A .4MOA load. A bedded 1984, 700 Remington BDL. I found Dr. Mike's QL data for node 5 using 150 AB/ PT's which I shoot at deer. Curious what 140/150s max out at with the short barrel, and percentage fill at max. Hogdon Reloading Center numbers show velocity and pressure at max loads but no percentage of case being full. Figured I need a faster powder and lighter bullet to compensate. PT's or AB's 140/150 grains likely. HRC shows H4350 and H4831 with decent speed and below 52 CUP/60Kpsi. StaBall 6.5 and Superperformance show promise as does Reloder 16,22. I live 15 minutes from Midway USA. Curbside pickup, no Hazmat or shipping fees. Grafs is 30 minutes away. 140ABs and all PTs are available. R16/23, H4350/4381sc, Superperformance are available as is Staball 6.5. Also can get Magpro, Hunter, Grand, Magnum, VV550/560, but think the slower powders will not get all burned. Nosler's Premium Ammo w/140AB's is rated at 3000fps likely from their 26-inch test barrel. I will likely lose 100-200+fps due to the 19 inch barrel. Likely use Partitions rather than AB's as they are more violent as they expand. I am open to suggestions. I have the dies, appropriate stud for my Lee case trimmer, shell holder, CCI 200 and Rem 9.5M primers. Attached is a picture of my buck euro I harvested Jan 3,2026 with a 50 cal muz w/290 Barnes TMEZ bullet. DRT 157 5/8 gross.

To be sure, I did run this projection at 61K max chamber pressure rather than the slightly lower max chamber pressure required by SAAMI. You should still get respectible velocities.

Nice buck!
I used RL19 with excellent results in a 22" barrel.
IMR/H4350 might be good with a 140 gr PT.

I've had good luck in a 280 with slow powder and mag primers, but not with a 19" barrel. N560 may do you well, or the powders JD mentioned. His load seems to consistently do well in the accuracy mark.

To be sure, I did run this projection at 61K max chamber pressure rather than the slightly lower max chamber pressure required by SAAMI. You should still get respectible velocities.

Thanks. It's a bolt action, will take the pressure, still below the .270 ratings. I like Reloder 16 for a 150 grain bullet. Available, temp insensitive, it fills the case, and burns all of it while producing 2849 fps, which is fast enough to do the job. Curious if these pressures are calculated with magnum primers or standard. Nosler uses Federal 210 in their data. I will likely use standards as I have 2000 extra. You shoot a 280. Is a 140 PT/AB too small for elk? They would run ~100 fps faster, flatter but then again "size does matter"! 150 PTs carry 50ft lbs more @ 400 yds than 140PTs @100 fps faster. Similar to 30-06 150 loads. Same case!

Nice buck!
I used RL19 with excellent results in a 22" barrel.
IMR/H4350 might be good with a 140 gr PT.

I shot the wrong buck just after sunset on a cloudy day. Thought he was another buck 20+ inches larger I had been seeing. Still a good buck. I ran ballistics for 140s vs 150s using partitions. At 400 yds the 150 has 50 more ft lbs assuming the 140 runs 100fps faster. 1883fps@500yds enough for good expansion. Less drift with the 150. RL 17 and 19 look good but are not available. I can get RL 16 and RL23. Magpro is available but is temp sensitive. RL23 is never available!

I'm thinking IMR/H4350 may be your ticket
