Hey any of you guys using 06h in a f std 308. If so how much and what speeds are you getting.

Super V,
Winchester cases 159/160 grains weight,45.8 grains of 2206H, 155 grain HBC,molly coated. HPS cases,45 grains 2206h,155 HBC, molly coated.Have shot to 900 metres at sea level with the first load,shot well. This is in a Barnard with a 32" trueflight barrel,it has a reasonably long throat,the junction of the bullet body and boat tail would sit about half way in the case neck. I can`t find any chronograph figures but they shoot just as well as 2208 loads that were in the high 2900fps area.

I get more speed with h than 08, from a lilja 308x13 3 groove. 3ooo fps with 46.1, just a small sign of pressure. The Stolle bolt was a little harder to lift.

Cheers
Darryl.

46 gn 06H in lapua cases behind Sierra 2155 projectiles in a Maddco 3 groove 30" 14 twist barrel gives 3020F/S at 15 deg c.
Have no problem getting 1000yd accuracy --no pressure signs up to 30 degc

Winchester cases, 45.8gns 2206H, HBC jumped, 32" Benchmark 12.4 twist, easy extraction.
Used JBM Ballistics data sheets for 2950, 3000, 3050 and 3100 to get yard come ups for Bendigo. Was exact to 1/8 click for 3100 FPS. JBM is a calculation so take with a pinch of salt. Have not chronoed to verify.

45gr 2206H behind 155gr SMK 2156 through 32" Benchmark gives me 3025 fps.

My 2206H is similar to the above post, 45gns in Laua case with 155.5 Bergers = 3035f/s checked yesterday with magnetospeed chronograph
now trying a bit less powder to give better ES.
