Tried again today.
ended up with
100m +2.0
200m -.6
300m -12 -15?(averaged) Very poor shooting Barrel quite warm, stuffed up an didn't check target after each shot. couple felt nice an couple not so, results varied.. dissapiinted in myself to be honest.
with so much heat im running out of light waiting for the barrel to cool, I threw the rifle in the truck with the aircon goin flat out, seemed to help quicker.
tomorrow arvo il punch 300 slowly

The name of your thread is, "Does this sound like 270 trajectory(?)"
After looking at this post my answer is a definite NO. It is about like 300 Savage trajectory.
I once did considerable shooting over a bench rest at ranges from 100 to 500 yards, with a good 270 rifle. I sighted 2 1/2 to 3 inches high at 100, which was about 3 inches low at 300. With 130 grain pointed bullets my load was either 60 grains of the old war surplus H4831, which is faster burning than modern H4831, or 60 grains of Norma 205.
At 500 yards the loads with the H4831 were 34 inches low and the loads with N205 were 32 inches low.
58.5 grains of the same powders put a pointed 150 grain bullet almost to the identical groups at 500 yards as the 130s were going.
However, I will point out that my thoughts on shooting and the methods I use, are so far removed from the methods that you, and the majority of shooters on here use, that we are not on the same page, we are not even singing from the same hymn book!
Examples of what I mean. I never let the barrel cool between shots, but simply fire five shot groups one after the other, as in normal bolt action loading. I can do this and consistently make either 1 MOA five shot groups, or very close to it, because my barrels are always bedded, meaning pressure under the barrel at the front of the stock. Thus, the barrel shoots the same, hot or cold.
I completely ignore what most of you are calling "nodes," at various velocities. To find a load for a bolt action rifle I keep upping the powder until I get excess pressure signs, like a sticking bolt, then I drop back a grain or so, until excess pressure signs go away, and that is my load for that rifle.
The first time I tried 165 grain bullets in my favourite 30-06 rifle, I used this plan. I had my loading outfit beside me at the range. I loaded one round with a charge of Norma 204, then increased the next one a grain, until after five rounds, when there was some sign of excess powder and the last round had 4 grains more powder than the first.
I fired each shot at a target at 100 yards. When I retrieved the target I found that my five 165 grain bullets, with the lowest loaded four grains less the heaviest, were all in a group that was half a bullet diameter over one inch!
Damn, I guess that stupid rifle of mine doesn't know a thing about those speed nodes you guys all talk about.
