Ban:

I received an email notification from you requesting info on Blue Dot and the 243 load data. I do not know if the "system" here is not working, or there is a fault in MY personal computer. However, I can not respond to the notification for some reason.

Therefore here is the attached report that I did last year. As always, work up carefully when approaching max loads.

Conclusions:

1. I consider the 243 much more versatile for a first rifle using these loads than starting a younger shooter out on a 223 or 22/250. It will duplicate the other two rounds, plus has the ability to handle a heavier bullet while still giving mild recoil characteristics.
2. The 243 offers a wide variety of bullets from 55 grain to 105 grain for hunting, and even 107 and 115 grain bullets for long range target shooting and competition.
3. Some bullets that are lighter than other bullets reach max pressure signs at lower powder charges, than a few heavier bullets. This is caused by the load bearing surface of the bullet.

Observations:

1. Contrary to what is usually seen, or expected: In using trees about 8 inches in diameter as backstops, I noticed that in the 2200 to 2800 fps range, most of the varmint bullets were actually penetrating thru the trees completely. Since they are suppose to be fragile for varmint applications, I did not expect to see this. However It was observed in the 55 grain Ballistic Tip, the 60 grain Sierra Hollow Point and the 75 grain Hornady Hollow Point.
2. Therefore it is my PERSONAL conclusion that these bullets might be considered as potential bullets on deer sized game in parts of the country where deer only get to be Antelope sized animals.
3. If this is done, the results are strictly the responsibility of the handloader and shooter. IN the 2200 to 2800 fps range, the rear core is staying intact and not exploding like is advertised a varmint bullet should do. Over this speed the bullet is performing in the explosive manner as designed.
4. I got input from other shooters on an internet forum asking about their experience with this bullet, there were some successes, some failures, and many recommendations for a larger bullet. However, if someone desires to use these varmint style bullets, I advise testing them yourself and analyse your results before deciding to use them.

As always, work your loads up from a point long before listed maximum.

I hope that this information is useful in teaching new and young shooters how to shoot properly and safely. Recoil will be substantially less than typical factory loads. This should assist in accurate shot placement by the shooter.

Cheers and Good shooting

First off thanks for the work developing these I have tried a couple of different loads in my 243 Handi and I have been pleased with the results so far. Way more accurate than my tests with H4895 loaded low.

One question I have is case head expansion useable as a pressure indicator with these loads. The main reason I am asking is that I would like to try Blue dot in my 204 Handi, but I don't want to run too hot in the break open. A pierced primer in that action does not sound like a good thing.

Seeing on how close the 204 and the 223 are in case capacity I figure the data should be close as well. My on thought is how will the smaller bore diameter effect the pressure. As I see it that case head expansion is a conservative way of determining a practical max.

aulrich

As a guide, in cases of equal powder capacity, loads used in a 224 bore diameter would be similar to those in a 204 bore with bullets in 204 weighing 60% of those in 224.

In other words if the load in a 223 with 50 grain bullets is "whatever it is" then the approximately the same load would apply to a 30 grain bullet in a 223 necked to 204.

Aulrich:

I bow to Mike 375 expertise,

Al I know is the smaller bore would cause higher pressures, with 223 data.

I would recommend working up. Of course the lower charges would not present a problem, but I would recommend working up slowly once you got near 10 grains of Blue dot or so.

I have no real reason to jump on the " trendiness " of the 204 Bandwagon. If I need that velocity, I have played with loads in a 223 with a 40 grains ballistic tip that will give me 4000 fps, and appears to give good case life, and I have not crossed the bridge or any pressure problems yet.

I have considered getting a 204 in New England Arms just to do some testing for load data. Then I would put another caliber's barrel on it tho.

If a 204 finds it way into my hands, I will definitely test it out and post the findings.

Cheers and Good shooting

I have to admit to part of my decision of going 204 was the "new and sexy factor". But the other big factor was the 204 came with an extractor not an ejector. this should completely eliminate the stuck case problem handi's can be subject too. That and getting pinged in the forehead with empty cases.

I have paid the price for the new and sexy factor. There is no ammo where I live and they don't know when the next load will show up. Just yesterday I got 100 brass off of ebay delivered it was a little expensive but at least I got brass.

A couple of side factors were being able to see the hits in the scope and a little better for fur hunting. The ssing you hits does seem to be true but the fur load is up in the air. The winchester loads seem to be the ones but it is too early to say.

Aulrich:

As far as seeing the bullet strikes in the scope, that is another reason I use Blue Dot in the 223s.
I get to see exactly that.
