Shot my first reloaded ammo.

[jkasandiego]

Thanks to all you guys,I've learned to reload my ammo.
Took my first batch to the range yesterday and it went bang
pics below is 55 gr. hornady v max with 24.5 gr IMR4064.
paper target shot at 100 yards with an Ar15 20" predator, scoped and bipod.




Need input to improve accuracy

Seemingly the case trim length and OAL/seating-depth varies a lot from round to round, that maybe issues that you may have to address.

You should also chrono your rounds, to figure out the average & variance in muzzle velocities.

PS. since you are local to me, you can come use my chrono if you don't already have one. We can also work on this together @ Rainbow range somedays.... I'm working on those Mk262-like loads as well as some M118LR-like loads(w/ 173gr bullets tho)

How did you prep your cases? Seating depth loots off on a lot of them as well. The necks on 1,7 and 8 look strange to me. Also you may want to get yourself some bags or a rest to test for accuracy. Bipod jump could have played a part in this.

I'm on a learning process right now. Need more a lot of input to improve this hobby.

maybe try seating some bullets without primers and powder to fix your seating depth problem. Get a bullet puller tool and unload those, please.

Yea, your overall length and case trim length are all out of wack. What are you using to trim cases? What type of dies are you using?

took the bullets off earlier.

I got RCBS dies..

I just ordered the chrono. i should get it by next week. Where is rainbow range?
I'm also starting .308 handload for my M1a.

gas cycled semi-autos, whether by an gas piston/oprod (your M1A0 or impingment (your AR), are tough on brass. The extraction is violent because this happens while the brass is still hot and expanded. Thus the need for very good sizing dies properly setup and case trimming.

I use Redding competition dies which I find are better than RCBS. If the brass shown in your picture is once-fired then reloaded brass, I'd say that either your dies are not adjusted well, or you need to find better brass.

The most reloading cycles I use for the AR and M1A is 8 per brass cartridge. Afterwards, regardless of the shape of the brass, it only gets used in the bolt guns.

I only run my .308 brass 5 times through the gas guns. But the .223 I am planing to run 7-8 times. I shoot the bolt brass till it splits unless I see it starting to fail. Get yourself the redding competiton seating die for .223, best 74.00 I ever spent, got one for .308 also

1,7 and 8 look very strange. pictures won't lie.

[PistolPete75]

ditto, oal seems to be inconsistant.

might also be a loose seating die. make sure it is properly screwed in right and tight. just like sex!

i've been thinking of upgrading my .223 and .308 to these redding competition dies. do they work on progressives? reason being is i use my dillon 550 as a single stage to load match grade for these two calibers.

[awheelman357]

the redding comp dies will work on your dillion ihave used on occasion with my 22-250 ackley imp.
