.270Win + IMR4350 + Sierra Varminter 90gr HP

I would say you are onto something with the IMR link. If I needed a load for the specific components you mention, I would use that starting load you mention at the listed COL and go at it.

My experience with the 270 is mostly with 130 grain bullets. But I have also found the 110 grain Hornady V-Max bullets shoot to about the same point of aim in my rifles as the 130 grainers and they give me good accuracy. I always use 4831 in either Hodgon or IMR.

I don't think you will have a problem with the 4350 powder in the 270. My concern would be the 90 grain bullets. My limited attempts at loading 90 grain bullets gave poor accuracy. Right or wrong, I blamed it on the short length of the bullets. You have to seat them deep enough to hold neck tension and then they have a lot of jump before reaching the rifling. But I will admit that I did not keep experimenting with them for very long in search of a pet load--hopefully your results will be better.

Best of luck, but if the 90 grainers don't work out, you might keep those 110 grain v-max in mind.

Thank you guys! Hmmm can you help clarify what you mean by poor accuracy? I guess I will try a couple of light to medium loads and range test them. I don't see having to shoot much past the 200 yard range where I will be coyote hunting.

I will definitely take the 100 and 110gr advice. I can find all sorts of load data for those two weights. I am thinking based on both of your replies and the fact that I can't really seem to find much info about loads for the 90gr round, that this is a common issue with the 90gr rounds for the .270Win.

Do you in your experiences (I still consider myself a newbie as I have only been hand loading for about a year now) think I might be able to drop the charge from the minimum of 56gr IMR4350 down to say 54gr? My thinking is that if I can reduce the velocity a bit I might be able to compensate for the accuracy issue.

From what I am learning by reading of others trial and errors is that the hotter the round the lower the accuracy. As of now I have my 150gr dialed for 50gr IMR4350 and I am pulling quarter size groups at 200yards consistently and that is about the middle of the load.

Anyhow let me know what you guys think and have a great Thanksgiving!

Glock 20, I always start with the listed starting load, but with that said, that can vary from manual to manual. For example, I am looking at my 48th edition Lyman manual where it lists a 90 grain hollowpoint bullet in the .270Win with 52 grains of IMR 4350 as a starting load and a max of 58 grains (compressed load). So 54 grains as you mention would certainly be within an acceptable range and I would not hesitate to try even 52 if I wished. Lyman lists this load at an OAL of 3.090".

In my work with 90 grain bullets, I did not get anything close to minute of angle, but I did not take careful measurements or keep anything in my journal as I do on most of the loads I work up. The results were that bad...to the best of my memory, they were all over the place, like a 3 to 4" spread at 100yards.

But I encourage you not to take my word for it...your results could be much different than mine. Your rifle may like them. When I am experimenting, I might work up 5 rounds at the starting load and 5 rounds with another grain or two and see how they react. I do know the OAL is something to pay careful attention to as well. It will be impossible to get the same OAL with your 90 grain bullets as your 130's. That is going to change things as much as anything. Lyman lists an OAL on jacketed 130 grain bullets at 3.250". I think you will definitely have to re-sight in every time you switch back and forth.

One of the beauties for me in using the 110 and 130 grain bullets interchangeably was I was able to find a load that both were on at 100 yards without having to sight in again.

Good luck in however you proceed.
