Because if you try to seat the gas checks the bullet will squash down.. I have tried it a few times and it squashes the bullets..243 Win--right?
Not bad. Why delete GCs? IME with #245496 it dotes on the checks.
Not as good with the checksPut some checks on and see if it does better.
Interesting challenge though. I'm enjoying it a lot. I like to get to the range early,no wind or very little. Didn't get there today until 11:30 and the wind was picking up. Thinking of trying some linotype sometime. Your right about the low node being complicated. Appreciate all the advice from some of the posters..You have some groups forming at different points!
Change in rifle rest , Change in follow through, Change in sighting or possibly changes in different brass neck tensions Also weigh your brass, I bet some weigh the same and some do not! Count out the different weights and I bet the individual groupings will show this! Light loads ( Low Node Shooting) is finicky! .1 grain of powder one way or another will change groups! Brass volume ( different between different lots) will change groups! I weigh my brass to + / - .2 grain
Low Node is more complicated them most folks think!
Typo. Should be 50.in the title, what's the "25" refer to?
Typo. Yes should be 50 sorry..My guess would be 25 yards.
At that distance, use a handgun.
Good post Ian. Folks seem crabby here as of late.Well I think you're doing great at 50. True, it isn't representative of "linear dispersion" and your 100-yard groups might be a dinner plate sized....or they might be very good also. I don't impose my standards on others, some people shoot .22 rimfire in competition to 400 yards or more and have the know-how and tools to do it well, to me .22 rimfire is a 50-yard cartridge at best and more like 25 for most purposes. Handguns are for fighting your way to the rifle you shouldn't have left behind in the first place in my opinion, or for backup. If you can make a ragged hole at 50 yards using one of the more notorious cast bullet "unfriendly" chamberings, then you're doing a lot of things right. Mr. Target and your personal satisfaction factor always have the last say in these things
