[QUOTE="OneShot0351, post: 715305, member: 28987"] [b]Re: 243 win. 105gr A-max H4350[/b] 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. [/QUOTE]
