I have used both,, bought the A&B on sale for around $60, have had tackdrivers , (not every one).. now they're about $100, and for the extra $45, get the Shaw.. I rebarreled an A3 Remington in 338-06, and it is sweet, a 98 German triple swastika proofed mauser in 300wsm, and it has killed two nice bulls this fall, here in Wyoming... I guided a young fellow from Texas to a 6X6, which he took with the 300wsm at 365 yds, and a week later, I killed a larger 5X5 with the same rifle at 382 yds, in his bed. ERShaw rules....Les
