Painless load development (mine)

[Castle Rock]

At the risk of being branded a "painful" reloader, are you guys getting 4-5 firings of 223 without annealing? (I'm assuming @Formidilosus's is "I never anneal")

I get over 15 on Lapua before trimming and annealing

Someone asked earlier in this thread about # of firings they get from 223 or 6 arc brass and IIRC they are shooting wiht an AR. I've not put a ton of firings on brass used in AR before but it's sure harder on brass than a bolt gun is so I wouldn't expect as good of results in that regard. Also, i'd bump shoulders more on brass intended for an AR so you're working the brass more.

Thatd be me!

i wasnt sure if id get more or less loadings. Gas gun pressures in theory would be less than bolt gun pressures (extending brass life?) and my gun is a stright pull repeater not semi-auto (extending brass life?)

My OCD tries to get the best of me a lot at the bench, and I do my best to force it back down. LOL!

Same here - the painless method is like a sigh of releif that i dont have to be so OCD about it, cause it just works

Yeah, i'd think a straight pull would be closer to a bolt gun in that regard and easier on brass. Probably doesnt get it all filthy like a gas gun does either.

Definitely cleaner, especially shooting suppressed

Yes but you're a neck sizing weirdo that doesn't mind resistance on bolt close.

Painless load development ?

300 WM
Max load 75 grains. First sign of pressure at 75.5 grains (bolt lift change)
Do I use max load (75 grain) or first over pressure load (75.5) when I back off to check first 10 round group?
With a 300 WM should I back off 0.5 or 1 grain?

Thanks

Addendum: I sent a DM to the OP. He kindly responded. Load until published max or any signs of pressure. Then back off at least 1 grain. My published max is 76.5 grains, I had pressure signs at 75.5 grains. I will load 10 rounds at 74.5 grains.

Another painless load dev done. Put this barreled action in a factory stock for now to get shooting and finish modding up a Stockys VG. Rifle is a Kinport Peak Rifles Tikka custom 6 Creedmoor with a 20" .75 taperless PBB blank. This is shots #4-14, shot 3 to get on paper, adjusted to rough in zero, 2 - 5 shot strings. Mild charge of 39gr H4350, 108 ELD-M @ .040" off the lands.
