22-250 Reduced Loads Using Blue Dot Powder

The following is information that I found outside of HPA. This experimentation was not conducted by me but I do use this information.

"Well, I don't agree with those above that the 22.250 can't do reliable service with reduced loads also... it adds to the rifle versatility with reduced loads...these loads are results I have tested, but ultimately the safety of such loads are the responsibility of the handloader himself as he is the only one that has control over his use of ANY data and the safety precautions of his handloading techniques...
That notwithstanding...here is some data you may find useful...

Blue Dot Range Report: 22/250

Firearm Used: Ruger 77 Mk 2

Barrel: 22 inch sporter weight

Case: Remington

Range Tested: 7 grains to 20 grains. 20 % ( 6.6 grains) 60 % ( 19.8 grains)

Full Case Capacity to Rim: 33 grains/

Bullets Used in Test:
46 Win HP, 50 Hornady SP, 52 Sierra HP Match, 55 Win FMJ, 60 Hornady SP
63 Sierra SMP


Test Results:

12. 18 grs: 3274 fps
13. 19 grs: 3388 fps ( Consider Max)
14. 20 grs: 3440 fps ( Extractor Mark, Scrapped Case)

II. 50 grain Hornady SP, Win Large Rifle Primer

1. 7 grs: 1722 fps
2. 8 grs: 1911 fps
3. 9 grs: 2057 fps
4. 10 grs: 2206 fps
5. 11 grs: 2328 fps

6. 12 grs: 2473 fps

12. 18 grs: 3181 fps
13. 19 grs: 3271 fps
14. 20 grs: 3354 fps

With this bullet, all the way to 20 grains was reached ( 60%). However, I would recommend max being set at 19 grains or less.

1. 7 grs: 1676 fps
2. 8 grs: 1841 fps
3. 9 grs: 1998 fps
4. 10 grs: 2127 fps
5. 11 grs: 2311 fps

6. 12 grs: 2416 fps
7. 13 grs: 2551 fps
8. 14 grs: No Read
9. 15 grs: 2795 fps
10. 16 grs: 2935 fps

11. 17 grs: 3029 fps
12. 18 grs: 3127 fps
13. 19 grs: 3252 fps
14. 20 grs: 3297 fps

This bullet also reached the 20 grains mark ( 60 %) . However once again I recommend max being set at 19 grains or less.


IV Winchester 55 gr FMJ, Win Large Pistol Primer

1. 7grs: 1636 fps
2. 8 grs: 1800 fps
3. 9 grs: 1986 fps
4. 10 grs: 2126 fps
5. 11 grs: 2247 fps

6. 12 grs: 2392 fps
7. 13 grs: 2504 fps
8. 14 grs: 2631 fps
9. 15 grs: 2738 fps
10. 16 grs: 2872 fps

11. 17 grs: 3003 fps
12. 18 grs: 3095 fps
13. 19 grs: 3203 fps
14. 20 grs: 3250 fps

As again Noted, this bullet also achieved reaching the 20 grain Mark ( 60%). However once again I recommend max capacity at 19 grains or less.


V. Hornady 60 grain SP, Win Mag Rifle Primer

1. 7 grs: 1587 fps
2. 8 grs: 1769 fps
3. 9 grs: 1901 fps
4. 10 grs: 2034 fps
5. 11 grs: 2162 fps

6. 12 grs: 2290 fps
7. 13 grs: 2406 fps
8. 14 grs: 2489 fps
9. 15 grs: 2618 fps
10. 16 grs: 2735 fps

11. 17 grs: 2832 fps
12. 18 grs: 2832 fps
13. 19 grs: 3058 fps ( considered max)
14. 20 grs: 3119 fps ( primer leaked, extractor marks, scrapped case)

Max was achieved at 19 grains. Recommend Max load at 19 grains or less.
Based on tree used as back stop, which had a 6 inch diameter to it, bullets at 15 grains of powder and up were penetrating the tree completely. Based on this I would recommend this point as a potential deer load for youths, keeping range within 100 to 125 yds or so ( 30/30 range). The 63 grain Sierra SMP showed a lot more damage to the tree than did the Hornady, and at a much lower velocity. Use on deer is the personal choice of the shooter or adult. Some argue against 22 Center fire on deer and others are just fine with it. Key is shot placement and range limitation. I am just reporting damage to media, and penetration that I am passing on to the reader.



VI. Sierra 63 grain Semi Pointed ( SMP) Win Mag Rifle Primer

1. 7 grs: 1455 fps
2. 8 grs: 1607 fps
3. 9 grs: 1848 fps
4. 10 grs: 1860 fps
5. 11 grs: 2034 fps

6. 12 grs: 2176 fps
7. 13 grs: 2327 fps
8. 14 grs: 2443 fps
9. 15 grs: 2578 fps
10. 16 grs: 2668 fps

11. 17 grs: 2787 fps
12. 18 grs: 2850 fps
13. 19 grs: 2958 fps ( Consider Maximum!, NO problems observed)
14. 20 grs: 2982 fps ( Popped primer, jammed bolt)


Conclusions:

For training and starting out a youth, I consider the 22/250 a better first choice to start out with, based on the test results as compared to a 223. The 223 has the economy of cheaper brass, but the 22/250 I thought offered more flexibility by being able to achieve higher velocities with heavier bullets than the 223 achieves.

For training of youths to deer hunt, the 63 grain bullet offered a lot of promise of everything tested. Results for a 64 grain Winchester would be close to the same, just recommend working up. Start looking for max with 18 grains or so. As one can see, the increase in fps is not that much, and would make no real world difference, as I consider that 200 yds would be max range. I also feel that training a youth not to take shots over that distance is a responsible habit for an adult to teach younger shooters. Let them learn with experience and practice to learn to shoot at longer ranges.

The 22/250 can be loaded down to levels that are between a 22 Long Rifle and a 22 Mag.
The recoil is very low, but also so is the noise at these levels. Especially the 10 grain loads and under. It can also be enjoyable for an adult. My own 22 mags are going to get dusty, as these loads are not only cheaper to shoot, but are more accurate? plus one can have a bullet of his choice instead of what the factory picks to load. At the lower volumes, such as 7 grains and up, these can also make a very satisfactory load for Squirrel hunting, or similar sized game at appropriate ranges. Consult a trajectory chart in some of the commercially available reload manuals. Even at 2000 fps or under, these would make good loads for calling coyotes if you can bring them in at 100 yds or so.
Game bullets would have the punch to drop a coyote at those velocities.

Important Notes:

These loads were tested in cool weather, moist outside and around the 55 to 60 degree ranges. Work up if the higher loads near max are to be used in hot weather.

Bullets were seated out to the magazine length in the Ruger. If your rifle has a tight neck, or a shorter chamber ( Rugers are generous) then work up your loads. Also seating bullets deeper can increase pressures.

Remember Blue Dot is a faster powder. However no filler is needed and I have tested it down to just 10 % of load capacity ( 3.3 grains and it worked just fine). It is not powder position sensitive in the case either.

This data represents data that I have observed. It is shared as a point of reference.
Outcomes are the responsibility of each handloader, who should be careful in his work.

The 22/250 showed me a lot of flexibility here, moreso than the 223 even.
It would be my pick as a better choice for a first rifle for a youth, utilizing this gathered test data.

Cheers and Good shooting
