heavy,75-90) gr. .223 loads

Savageshooter: realizing all rifles are different, just had a Hart 1-8 put on my pre accutrigger mdl. 10FP, bought new Aug 2000). Tight, no-turn neck, .253" cut with my Pacific reamer, .072" freebore, Lapua brass, Fed 205, seated to touch. Holding 1/2 moa with 5 shot groups at 300 yd with: 25 grs. Varget, 69 gr. Sierra #1380. 24.0 grs. Varget, 75 Hornady HPBT # 2279. 23.9 grs. Varget, do you get the idea I like Varget?), 77 gr. Sierra HPBT # 1477. The 75 Hornady is showing a slight advantage over the 77 gr. Sierra, but will compare further. My son had his mdl 10FP re-barreled, by the same 'smith, using the same reamer, but with a 1-7 twist Hart, and using the 80 gr. Sierra & Bergers, with maximum charges of Varget for his F-Class matches at 600 yds., and winning with that combination.
 
As already stated any of those will run through 1-7" just fine, plus I have used the Sierra 90 gr. Match Kings with Varget and got excellent results.
