A while back seafire posted a list of 22-250 loads using Blue Dot. I looked for it but can't seem to find it. Anyone have a link to it? Thanks

yeah...... just be careful with them... as Mom told Ralphie.... You'll put your eye out kid!

hope this helps ya out....

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

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.

Thanks for posting. I’ve played around with reduced loads in a 243 while training some youths to shoot. A lot of fun.

Great information John! Thank you so much for all your work and willingness to share this information.

Thanks a million seafire

My pleasure guys....

I can see a need for using BD if you wanted to shoot 52s @2500 in a 22-250. I ran the numbers on QL with the 53gr / 20gr and almost 3300. After adjusting to get the speed with 20gr of BD the pressure was 61,000psi. Most normal 22-250 powders will give that speed with 45,000psi. Yes it can be done, but running BD at the high end dose not seem to be practical. In the 6 or 7 rifles that I have used BD on, the most accurate loads were between 35 and 44% . Above that point the accuracy went to hell. Just my thoughts.

I used 14 grains of Blue Dot under 3 different 45 grain bullets, Speer, Sierra and Hornady. Shot great, couldn't ask for better. This has turned out to be my around the house raccoon and coyote load. Or my dumpster/chicken house protective load.

Easy way to ring a chamber. Be careful

Just what would be the mechanism for “ringing” a chamber with BlueDot? This has happened with reduced loads and a filler or wad (in fact Lyman stopped recommending a filler over 20 years ago), but not to my knowledge with just a high pressure load.

I’ve had great accuracy with the 55-grain Nosler BTip bullet over 17.5 grains of BlueDot, never chronographed it though. As with any fast powder there is a risk of a double charge, but more reloaders blow up their guns from mistakenly using the wrong powder than from using BlueDot. Reloading can be dangerous, be careful!

If noted, I have always recommended max charge in a 22.250 with Blue Dot to be 19 grains....
and have ran loads to 20 and over, with no gains.. yet posted the 20 grain loads that failed.. due to primer issues..
just to prove the point of why I recommended stopping at 19 in that particular case...

I like Blue Dot but it has to be measured with a trickler, meaning shot to shot variation is kept to a minimum. Past that I am only 3/4 of the way through my first pound having used it in 45 Colt, 44 magnum, 444 Marlin, 223 and 22-250. That has been a lot of shots!

on the other end of the spectrum... I pretty much used it in the 223, with some minor use in the 243 last year..
average 550 plus rounds out of a pound of Blue Dot....last year was a light year for B/Dot use for me as I was seeming to reach for 4198 a lot more... so I only ran thru 7 pounds of Blue Dot last year....one five pound jug and two single pounders...

My ADL 223, I'm well over 10,000 rounds down the barrel with Blue Dot, and the old gal is still shooting tight groups...
and I've been waiting to burn the barrel out, to pull it and replace with a one in 7 twist...which I wonder if its ever going to happen, since I've got 2 700 take off barrels in 223, with one in 12 twists that have never been shot...

A burnout on Blue Dot? Ain't gonna happen. There's so little extra gas after it hits maximum power, so much of the burn happens in the case, you might as well give those barrels good new homes.

But Seafire's cautions are not to be ignored. Blue Dot's behavior is like a light switch, it's docile until it's a beast. Tenths matter.

Seafire: Is there a reason that you are now using rifle primers instead of pistol primers.?

I can't answer for Seafire, but in my own use, keep in mind that Blue Dot generates RIFLE pressures. Some pistol primers are just too soft, although in small rifle cases they can work really well, just enough spark for good ignition without the primer blast moving the bullet before the powder starts to generate power.
For me, I use small rifle primers with BD. I have a box of Federal pistol primers that I have been using with a Fireball load, with excellent results under Lil Gun and 4198. I forget the number on the primers, but they're just primer primers, not magnum, not match. The cups get flat but no cratering.
If you want to try pistol primers, I would start with those that are recommended in snorty pistol cases, like 357, 357 SIG, 41 and 44 mags, the pistol calibers known to generate stiff pistol pressures. Something that's recommended for say, 25ACP, probably won't be able to handle Blue Dot.

Probably the dumbest answer you'll ever get on the campfire, but its the truth...

I was using pistol primers back when that load data was developed..

Obama is no longer in office.. so I can purchase rifle primers readily...

back when he was in office, pistol primers were often all you could find on the shelves around here..
and I don't think this area was alone in that fact..

everyone on the planet were busy hording them back then....

And now you know you can hoard successfully!

update... not now with the Corona Virus we're dealing with... people are back to hoarding again...

But it would take a couple of years for me to be short of primers of any type I use, since Trump's been in office...

Seafire; I have always uses pistol primers as per your original formula. In going to rifle primers have you seen any major changes with the same loads besides a higher level of safety at the higher percentages? Speed -consistency-accuracy? PS: With your 50gr Hor Sp --- 19gr of BD load, QL shows 100% burn in just 2.24"

a hair more velocity over the chrony with Small Rifle primers.. but nothing to get too excited over...
accuracy can be a little tighter groups at 100 yds or so.. at 50 yds. I've not noticed anything special...

I know it doesn't take much barrel length to get 100% burn with Blue Dot, but I appreciate the info of 100% burn in the 2.25 inches...

Side note:

I don't know here personally, but I've share these loads a long time ago with a buddy in Montana..
who shared his with a good friend.. who loads ammo for his Indian Grandma who lives on the Reservation

She's 4'11" , is a widow, and owns one rifle... a 22.250.. and has for decades...

she doesn't really elk hunt, when she is getting low on meat, on the Rez, she shoots elk on her property, off the front porch
or out a window...head shots.. 100Yds or so..she loves the low recoil of the Blue Dot loads her grand son loads for her...
18.5 grains and a 55 grain Hornady IIRC.. bang flop and then she's on the phone with some of her sons or grand kids...
"get over here and gut this elk for me and then take it to the butcher shop"

:Love its helping out some 70 yr old Native American Senior Citizen

Seafire, I was the OP on this thread. I asked for the 22-250 info because I had just purchased a as new Striker in 22-250 for 340 bucks. This is my first 22-250 and first Striker. I've got several XPs, Contenders and Encores. Most everyone hates Strikers because of the horrible triggers that are impossible to do anything with but for 340 I thought what the heck. Well, the trigger is horrible and I can't do anything with it but I have been having fun with your Blue Dot loads in it..Blue Dot works fantastic in the shorter barrels and the recoil doesn't beat you up.

Thank You

J:

always happy to help out a fellow campfire member...

glad it worked out for ya....

cheers and best regards!
