Looking to duplicate factory load

I'd like to find out what powder and load would most closely match the Win. white box .223 45 gr. jhp @ 3600 fps. I'd be ok with 40 gr. bullets as opposed to 45 or 50. It's the powder and speed I'd like to match.
Thanks
 
its a ball powder, might be W748. I pulled some apart years ago

Winchester sells a 46 grain hollowpoint as a component for reloading

WHen I chrony'd the 45 gr load in my 223, it did 3280 f/s average for 10 shots (22" 1:12 twist 700)
 
Who knows what the factory uses... and who cares. Check out Hodgdon's reloading center, as they are now 'in charge' of Winchester powders.

I use 335 myself but there are 'faster' ones there if you punch in what you want. Leave manufacturer, bullet wieght and powder blank for more data options.
edit to add... you should really be looking to reload for accuracy vs factory duplication anyways?. I don't know of any critters that can tell if you're 200fps short of a factory load. If its a 'defence' load you outta look for heavier projectiles.

What's your rifle? I know of quite a few that find 50grain vmaxs peppered with h335 absolutley fantabulous.:D
 
What twist is your rifle? Which 700 is it... SPS, BDL, LTR, VLS, etc.?

If it's a 1:7-1:9 twist I can almost guarantee it's going to like a heavier bullet:
68grn Hornady A-Max
69grn Sierra MatchKings
77grn Sierra MatchKings
Over 25-26grns of Varget in a Winchester case with CCI BR4 primers.

If it's a 1:10-1:12 Twist then the former recipes should work well. (I don't own a lower than 1:9 twist so I can't help there)
 
I use H335 and VArget with 5 gr Vmax bullets, don't believe the velocity on the Winchester box, they are dreaming in technicolour. They chronrographed ib my rifle at 3300 fps.
