shooting loads for accuracy

[Kevin Stenberg]

I was on CB going over some stickies. I was reading a thread about shooting different loads to find the best accuracy. An how 1 group of rounds affect the next group.
As an example. you shoot a string of say 3.5 grains of Red dot. Your next load bracket is for 4 grains of Rd. All components are the same except the powder quantity. Has anyone found that you need to shoot a few of the 4 gr. loads to . In a sense season the barrel because of the switch from one load to another. Before testing for the quality of the second load.
I have a hard time splainnin myself. I hope you can get my drift.

No, not with an example like that. Switching from Unique to Varget, maybe the first shot to clear the pipe.

You really need to have your BS filter on over there.

Lube changes will need some shots to get a consistant bore condition. Some powder changes matter, some don't. Not sure how much powder matters with cast but it sure can with jacketed.
Going up in charge with same lube and powder? No need to do anything but shoot.

300 BLK is right, keep the BS filter on high over there these days.

I think they have different key boards over there.

I'd be more concerned with letting the barrel cool down, between strings.

 

[KHornet]

Would be inclined to run a patch between loads. Just my opinion!

About all I do that's somewhat relevant is routinely "dry mopping" bore.The reasoning being hunting and cold bore,first shot predicted hits/location.

It does give insights....whether that works for benchrest accuracy,and load development....couldn't say.

Each rig is a rule to it's own though.I'm not changing components all that much....learning to change load(pwd amt) with the conditions.But that's with the same powder/bullet/lube.

You said a mouthful right there! Ain't it the truth.
