Savage Model 10 rebarreled with a 10" twist A&B barrel (bought the barrel used for $40.00 and rechambered it from 6mmBR to .243 Win).
55g NBT @ 0.020" off lands, 44.0g IMR4895, Wolf Large Rifle Primer, Lapua Brass.
75g V-Max @ 0.020" off lands, 44.0g H4350, Win brass, Wolf Primer.
95g NBT @ 0.020" off lands, 44.0g IMR7828, Rem Brass, WLR primer.
They all shoot into 1/2 MOA groups.
The loads were developed at different times. I'm a bit surprised the powder weights all came out the same, but they did.
