My apologies to those that are tired of seeing the words Blue Dot.

Per the request of several people, I did manage to finally get out and do some tests with the 270. Forgive me but the weather has not been real cooperative in Oregon lately to do anything, unless you are a DUCK.

I was noticing some pressure problems with the 30/06 when I tested it, that it was not able to get to the 50% of max capacity before it was exhibiting pressure problems with the primers. I was shooting for over 50% in these loads since some guys have talked about the fear of a double charge.

2400 fps seems to be a good benchmark of the top end of MV without redlining pressures.

At the request of those who were interested I picked a 110 grain Sierra and a 130 grain Hornady Bullets for testing.
The Hornady was seated to the cannelure, and the Sierra to the same overall length.

Necked sized Rem brass was used, with a CCI Large Rifle primer.

Max Case capacity was 50.6 grains of Blue Dot.

I chose to start at 40% of that figure, or 20 grains of Blue Dot.
Because I had pressure problems at 48 % in the 30/06, I stopped at 24 grains or 48%.

Rifle was a Winchester Model 70 with a Boss.

110 grain Sierra:
1. 20 grs: 2196 fps
2. 21 grs: 2232 fps
3. 22 grs: 2302 fps
4. 23 grs: 2419 fps
5. 24 grs: 2447 fps

NO pressure problems noticed at all.

Hornady 130 grain SP
1. 20 grs: 2092 fps
2. 21 grs: 2117 fps
3. 22 grs: 2113 fps ( yeah less than above)
4. 23 grs: 2181 fps
5. 24 grs: 2237 fps

No pressure problems noticed again.

Since I had no pressure problems at 48 % or 24 grains, I will work up loads until I hit 2400 fps with the 130 grain bullet, for the sake of testing.

I am sure the 110 grain bullet can be pushed to higher velocities but everyone has to make a personal decision if that fits their applications. The 110 grain is recommended by Sierra for Deer also,even tho it is listed as varmint bullet. It should be a great application for kids with a 270.

IN the 130 grain range, I would recommend a Ballistic Tip for that application, due to its accuracy and ability to open up well at that velocity.

if people are interested in results in a 140 or 150 grain bullet, I may consider the tests if I get a response. Although I would prefer a heavier bullet than 130 in the 270 myself, I think the 130 is going to be more than adequate for the application, deer in a low recoiling rifle for women and kids.

2250 fps, zeroed 3.5 inches high at 100 yds, would be dead on at 200 yds.

Cheers and good shooting

Seafire, very interesting. So what is the recoil and noise like with these loads? I might try some of these in my 270 just for fun. Do you think Green Dot would work about the same, or is it too fast? I just happen to have a couple pounds. Probably would have to buy the Blue Dot. Thanks for sharing your info!

Wash Hunter:

Green Dot will yield slower velocities since it is a faster powder. This info would not be interchangeable with Green Dot.

I can't answer the question on Recoil, except that is very light in any of these loads. Similar to a 22/250 or even a 223 in some rifles.

I also can't answer the question to Noise Reduction on this load but it has proven to highly reduce noise over a regular factory style load.

I highlighted that the test rifle has a BOSS on it. So recoil is even reduced more, with a Boss and the Noise is actually increased to the shooter because of the BOSS.

Similar in noise to a 223 I think is also a fair analogy.
At 2,000 fps any of these loads are definitely in the 223 in a varmint weight rifle, class of recoil.

good luck if you try it.

Cheers and Good shooting

seafire/B17G,

I might give Blue Dot a try in my 270's using the Lyman 280642 bullet. They weigh in at right around 150 grains. I have been using 20 grains of WC-680 which is quite a bit slower than Blue Dot with no problems at all. Accuracy is very good at 100-150 yards...BCB

Ahh, thanks. I do not have a chrono, but I will work my loads up for accuracy, checking for pressure signs along the way. Thanks again for the research.
