A limited check indicates that three target rifles were available on or shortly after introduction of the Model 70. They were the National Match Target, in .30-'06 with a 24 inch barrel; the "Bull Gun" in that caliber plus .300 H&H with a 28" extra heavy barrel; and the standard target, with a 24" medium weight barrel, which was available in any standard caliber. All had target stocks.
The only Model 70 called a "Varmint Rifle" was introduced in 1955 in .243 Winchester only; it had a target weight (not an extra heavy) barrel.
