Seeking the Best Powder for 300 PRC Reloading

I’ve been getting into reloading for my 300 PRC and I’m curious about what everyone thinks is the best powder to use for this caliber. I’ve seen discussions about different powders like H1000, N570, and a few others that are popular among long-range shooters.

Why the Right Powder Matters

Choosing the right powder can make a significant difference in accuracy and performance, especially when it comes to long-range shooting or hunting in challenging terrains. With the 300 PRC often being utilized in mountainous areas or during long-distance hunts, optimizing load variables seems critical.

What I’ve Considered So Far

Here’s what I’ve gathered on some of the popular powders:

  • H1000: It’s known for providing consistent velocities and excellent accuracy. It’s been recommended by various users for its ability to perform well across different temperatures.
  • N570: I’ve read that this powder has a higher energy density and can produce impressive speeds. However, I am concerned about the consistency and how it can perform in varying conditions.
  • Others: I’m also curious about other powders that might not be as mainstream but could potentially offer good performance.

Questions for the Experts

  1. What are your experiences with these powders? Are there any hidden gems I should know about?
  2. Do you have any tips for load development specific to the 300 PRC?
  3. How do environmental factors impact your choice of powder and load?

Looking forward to hearing your recommendations and any advice you might have!

Happy shooting!

I’ve had great success with H1000 for reloading 300 PRC. It provides excellent consistency and accuracy across various conditions!

H1000 is indeed a solid choice. However, I’ve also heard good things about IMR 4350 in terms of velocity and consistency. Anyone else tried it?

4

I’ve primarily used RL26 and found it to yield amazing velocities! It also performs well in colder weather, which is a plus for winter hunting.

5

IMR 4350 is definitely worth considering. I just haven’t found it to be as temperature stable as H1000.

6

I’m with you, jrobinson! H1000 handles temperature variations so much better compared to some others I’ve tried.

7

If you’re looking for punchy performance, I recommend trying Norma MRP. It packs quite a punch with great accuracy! Just my two cents.

8

I’ll have to check out Norma MRP! Always looking for new powders to experiment with.

9

I’m curious, has anyone had issues with ES and SD using different powders? I’d like to pick the most consistent performer.

10

Shed some light on the powder selections and I’m in! I’m quite picky and want top-tier performance. Any suggestions to avoid the learning curve?

11

I’ve definitely noticed that H1000 has lower ES compared to others like RL23 in my tests.

12

Let’s face it, trying out all these powders gets expensive! Can’t we just agree that there isn’t a ‘best’ one, only the best for us? LOL!

I’m finding that H1000 offers great velocity with consistent performance for 300 PRC. I’ve had fantastic results with less pressure signs, too. Anyone else have experience with it?

14

I’ve had the same experience with H1000! It’s consistently produced tight groups for me. How are you measuring your pressure signs?

15

I prefer RL-26; it seems to give me higher velocities while maintaining acceptable pressure levels. Just be sure to watch for temp sensitivity, though!

16

Great point about temp sensitivity! I’ve noticed variations in my groups depending on the weather. Any tricks to mitigate that?

17

Having used both H1000 and RL-26, I can confirm that H1000 is less finicky in varying weather. But I also had success with IMR 7977; it surprised me with its velocity consistency.

18

Interesting! I’ve never tried IMR 7977. How does it perform with pressure signs?

IMR 7977 is solid! Minimal pressure signs for me, even at max loads. I think it’s an underrated powder for the 300 PRC.

Have you tried any of the Hodgdon extreme series? I heard they perform well in 300 PRC, especially with their temperature stability.
