Re: 243 win. 105gr A-max H4350
I AM NEW TO RELOADING SO ALL INPUT AND SUGGESTIONS ARE WELCOME!
Thanks, that all helps gives me more powders to look into if i am not getting the velocities i want.
Not able to get to my chronograph till Sat. so velocities and SD were not available at the moment to even see if im getting the speed i want. It was rainy and 44 degrees today but i had time and had to go ahead and shoot and get a ball park idea of what this rifle would do, as i did the break in w/ 115gr dtac corbon factory loads all groups 1-2"
where I am now. Lapua brass(from the corbons), cci 200 primers, H4350, 105gr A-max, all loads just touching the lands. COAL 2.804
Shot 5 4shot groups(20rnds) cleaning and letting cool between charge increments.
Heres the groups, i will list 4 shot groups and omit a "flyer" for best 3 shot group.(no pressure signs at all brass and primers are great)
charge 39.0gr: (4).936 (3).657
39.5 : (4)1.062 (3).522
40.0 : (4)1.422 (3).987
40.5 : (4).936 (3).307
41.0 : (4).657 (3).437
I am hoping when i shoot thru the chrony Sat. my velocities @ 40.5 and 41 will be at least in the 2900's. and deviation is close. i guess accuracy before speed though.
just wondering where to go from here back off the lands at 40.5? shoot more groups w/ 40.5 and 41 to get a more consistent idea of which one to work with, also what increments are recommended when backing off the lands?
In a Nut Shell what im trying to say is for the experienced reloaders out there, where to go from here what to try next if this was your rifle.
If I had to choose between taking a civilian or POG on a patrol, I'd happily take the civilian. At least he hasn't made the conscious decision of being a coward in the military yet!"
