Hello all! I am new to the forum and new to SMLs. I am an avid shooter and reloader, but this is all new to me. I have a rifle that should be done in a month or so, and I’m trying to get components together for loads. Given how scarce things still are ,if I need something I don’t have, I need to quickly source. Seems like you gentleman are way ahead of the curve, so maybe you can start me out on the right path.
Gun: - Arrowhead obsidian - 26” brux carbon fiber - Arrowhead LRMP ignition - Shooting 300 grain NSRs
Desired load characteristics:
1. General hunting load for medium sized game (mainly deer) 2. Stable load, to the extent possible, across a variety of hunting locations, temps, etc.. 3. 2850+ FPS ideally 4. Clean burning to minimize barrel cleaning as much as possible 5. Obviously minimal recoil required to get the job done, but I can manage this within reason. I do have a break being installed on the gun. 6. And hopefully in a powder I can find. I have most of an 8lb jug of IMR 4198, but not sure that hits the velocity mark in a 26”. I will defer to the masters here. Aside from that I don’t have anything on hand that I think would be in the burn rate range appropriate. I am learning most of my powders I use for centerfires aren’t appropriate.
Arrowhead prefers H322, but that stuff is like a unicorn these days it seems. If anyone near Alabama has some they want to sell I’m interested. They also mentioned benchmark, but I’ve read mixed results.
Can some of you much more experienced in SMLs point me in the right direction?

For starters I would be leaning on the builder for load data. Your builder should be able to give you load data for IMR4198 with a 300 grain bullet. If they can’t provide you with that information I would be asking for my money back.
Lots of info on here for 4198 and a 300 grain bullet.
Unfortunately, arrowhead ignition, carbon fiber barrel and NSR bullets is something can’t help you with.
Good luck and let us know what you find….

Luke at arrowhead said he would provide a few suggested loads with the rifle when it ships. I was just hoping to get a head start on finding some powders that others have had success with given how hard things are to find.
Luke and arrowhead have been great and I do not want too imply otherwise. I just wanted him spending his time finishing my Rifle and I can find some load data on my own.

Benchmark works great with 300gr bullets. Use the “search” function here and you’ll find plenty of load data for that combo. Here’s an example from hillbill…. ![](https://i.postimg.cc/s2hkMNKh/IMG-1312.jpg)

NSR bullets? No sizing required? Keep in mind if you use any other bullets you will need a sizing die, matter of fact I’m not sure you wouldn’t be better off to go ahead and get one so you can try several different bullets. IMR -4198 will work pretty well, others are less temp sensitive but use it since you have it.

To add With 300 weight bullets Benchmark, IMR-8208, H-322, 4895 and others work well I use mainly 8208 and Benchmark It depends on how fast you want to push your bullet and if your barrel profile is up to the task
