Thanks for that picture, Viking338 - shows what I was saying exactly! You've got it set up for a good stiff crush-fit on chambering, too - excellent.
Just wondering if the 270gr. you've picked is soft enough to expand well for that low speed.

You may be right Daryl but there is only one way to find out.

Ok , I loaded 45 grains of 2206H under the 270 grain RN and only got 2080 fps.
I then loaded 46 grains but there wasn't enough light for the chrony so not sure on velocity.

Still a ways from max as you can see in the photo.
Front row of 3 are the 45 grains.
Back row of 3 are 46 grains.
Extraction was fine.
Hope to get time on the weekend to do a bit more with it.
