Thread: 2208 in 284?

Just an update regarding powders for the 284. I have been using 2209 recently with no real issues. However just to try something different I decided to try some Winchester 760. This is because thier stated data with 760 showed the max load a few Grains less than the 2209, for roughly the same speed. This was important to me as with 2209 I was getting compressed loads, yet no real pressure signs. So I wanted to try a powder that left me a bit of wriggle room. So I loaded a few different loads up with 150gn Ballistic Tops and headed to the range to see how they went. I am pretty bloody happy so far! As I am not really a great sort by any means.
This group is half a grain below max...


And this one is at the stated book max..


Neither leads are showing any pressure signs, so I will push it a bit further. Although I will wait for the Forum Chrony to get here so I can check the speeds.

The only thing that had me puzzled was that some rounds would not chamber. Now this is using brand new brass. So are you supposed to run new brass through a sizing die first?
Cheers

W760 is same as H414. I've been using H414 in my short barreled 284 with 162 Amaxs for a few years now. It's a bloody good powder.

Yes that is why I tried the W760, as I had read about people getting good results with the H414 and W760 was readily available here. Can't wait to see what speed it produces.

Hope your shopping at Belmont for your powder...
Cheapest by along shot.

Hi bro, The win 760 powder is doing really good on my 284. If I do my part right easy 1/4 inch group at 100m , however, win 760 is temperature sensitive! Same loads, from summer to winter the velocity drop about 4 FPS per degree. Do you use the same load all year round and adjust the velocity data on the ballistic app if shooting long range?
