Yes it was.

I had a local chap put a 27" .260 Rem (rifled 4140 contoured blank - chambered long by Jeff Lawrence) on a 1950 M98 action.

I think the twist is a standard 9". I had threads put on the barrel as I received it. This long chamber fit a 7x57 necked to .264 perfectly, using a normal .26" neck. The case ended up holding 60gr. water, same as the 6.5x284, I have read. I called it the .260CLC, for Carol's Little Ctg. Yes - the CLC moniker was plagiarized by me from Layne Simpson, I believe as he named a 6mm on a .222 case, I think it was, for his daughter.

With the 60gr. capacity, this 27" bl. delivered 3,308fps using Re#19 powder and 120gr. XLC Barnes Blue Coated bullets & would put 5 of them into 3/4" - no change to the muzzle, except for re-crown.

At that time, my .264 Winchester magnum made 3,358fps with the same bullets, but used 30gr. more powder (H870) to do it. I rebarreled the .264 WM to .458 - LOL.

As the recoil generated by the .260CLC was more than enjoyable for my daughter, I had my friend set the barrel back to exactly headspace on standard .260 Rem. factory brass.

This standard .260Rem. chamber, in this splendid Laurence Barrel shoots just under, to barely over 1/2" at 100 meters, 5-shot groups with all bullets tried so far - 85gr. HP, 100gr. HP, 120gr. XLC, 140gr. Interlock. The 160gr. Sierra Semi-RNI with a mere 34.0gr. H4895 (soft recoil), can only manage to get into 1.125" 5-shot groups with me shooting.

After we found Carol could shoot it well with this load, and with the scope taped at 4X, Carol put 10 consecutive 160's into 1 1/2" with 8 of those in 1". Bench? Well sort of, elbow resting only on the concrete benchtop. It gets better, as the 'target' was a solid black deer silhouette stapled up at 100 meters (109yards) - solid black - no aiming point, no marks. She said, where do I shoot it - I said, "you know where, behind the elbow" - "just kill it, Carol" - she sure did.

Obviously, she is a natural, a talented rifle shot and, of course had to have had an exceptionally good teacher, eh!
