The difference between 4 and 5 doesn’t sound as bad when someone else says it.
I’d just prefer to not give up what I have. If possible.
120 grain Partitions will be as light as I go.
I have 243/22ARC/223 for smaller.
I know brass is an issue. I have about 250 pieces of older Remington, with 100 of that being new from the 90’s.
I think that will suffice for my needs from this rifle.
And I’m not opposed to resizing other cartridges to get what I need. The correct head stamp isn’t an issue for me.
And I’m pretty set in cartridge. It was given to me as a 257 and unless something unexpected happens, it will stay that way.
Any info on the difference in velocity between standard chamber and AI?
Thanks.
I’d definitely improve it just to make the brass last longer. Love mine, but I didn’t twist it fast because it’s built on a Model Seven, so doesn’t have the mag length for long bullets anyway. Don’t have a standard 257 to compare to as far as velocity goes. I don’t think you’re going to lose magazine capacity. Seems like that is going be driven mostly by the largest diameter, and that won’t change.
