.260 Remington

I shot (5) more of the 130gr Norma just now @ 250 yards. I split the seating depth difference, and managed a 1-1/4 to 1-1/2 inch group (can't tell what is an old mark and what is new on this target)...so about a half-minute again and in-line with the 100 yard tests from yesterday.

It took .6 to get there, so I might be going a bit faster. It'll be a couple weeks until I take this to 650 and know for sure.

Same load data from post #443 above.

Yeah, I did like that I could use .5 at 200 and 1.1-1.2 at 300. Easy peasy.

You just made me realize that I'm sitting on about 7.5lbs of IMR-4955 (H4831 equivalent). Might have to do a little testing with that down the road.

TBH, I have the 4955 because it shoots so well out of my 7RM with 150gr bullets.

I like h4831 I get the velocity I want without the early pressure spikes that h4350 give me in 260

Both SC and regular cut? Or just SC?

N160 is right there with burn rate as well. You'll most likely compress the load before you run into pressure signs.
