OK, I am interested in learning what methodologies and thought processes everyone use to determine the starting load given some available information.
Bullet: Everglades .223 Rem 55gr FMJ with cannelure BT (V2)
Power: H335 (let's assume this is the power of choice regardless it's good or not)
Rifle: Remington 700 SPS .223 rem, 26" heavy barrel, 1 in 12" twist rate
Below is a list of load that I collected from various sources:
Hornady Handbook 4th Ed. (DOC-16, pg117): MIN=21.4/2800, MAX=25.4/3200 (for #2267 FMJ-BT w/c)
Handloads.com (DOC-31): 25.5/unknown, OAL=2.245”, CCI SRM premier (guest source)
Hodgdon Online Manual: OAL=2.200”,MIN=23.0/3018fps/40800cup, MAX=25.3/3202fps/49300cup (55gr SPR SP)
Hodgdon Online Manual: OAL=2.180”,MIN=21.3/2920fps/48900psi, MAX=22.7/3063fps/53000psi (55gr BAR TSX FB)
Hodgdon Online Manual: OAL=2.220”,MIN=21.4/2969fps/47000psi, MAX=22.8/3099fps/51800psi (55gr SFIRE)
LEE Manual, 55gr Jacked, MIN=23gr/3018fps, MAX=25.3gr/3203fps
LEE Manual, 55gr BAR X Solid, MIN=21.3gr/2920fps, MAX=22.7gr/3063fps
Spear Manual, 55gr FMJ BT, MIN=24.0gr/2805, MAX=26.0gr/3092
H335 bottle label, Spr Sp, 25.3gr/3203fps (does not show min/max)
I noticed that for different bullets in above list, some of the starting load is more than another's max load.
Thanks for showing your thought process and methodologies in working out a starting load for the first range visit. Also when start load is selected and what is the measure for selecting the best load data? Other than best the grouping, is there a favorable velocity range that the .223 needs to satisfy?
