I am having a 1/8 twist .223 remington built on a M700 action. I will be using Hornady 75 gr BTHP's, 75 gr A MAX's and 77 grain SMK's. Does anyone have any load advice?
Thanks for the info! That velocity sounds good, cause my rifle being built will have a Broughton 5C 26" barrel. What powder charge is good to use with TAC?
I've run TAC, H4895 and Varget in my 1:9 Wilson barrel w/ a Wilde leade. The first powders provided, for my barrel, the best accuracy. Pick a bullet and run with it 1st, trying different powders. Hopefully you'll find your load. If not, pick another bullet and do it again.
I use a 1-8 twist .223 Rem both bolt and semi. Here are a few loads. To get the best out of the 1-8 {depending on barrel length you might try Mk's or Berger 80gr'ers.
80gr. Varget [24.2 grs] Rem 7 1/2 BR vel's 28" barrel 2950 fps
80gr. VV-N150 [25.0 grs] WSR vel's 2950 fps
80gr. VV-N540 [24.5 grs] 7 1/2 BR vel's 2925 fps
77gr. Varget [24.0 grs] vel's 2800 fps in a 20" barrel AR.
Unless you need the repeating box magazine of a bolt rifle, I'd put in a Sinclair mag block for M700 SA and shoot the 80grs.... there a hoot in a 1-8 twist rifle at LR.
