The .22 rimfire guns and .30-30 336s are still made with Micro-Groove rifling.
Winchester was making news with its sleek, new Model 88, chambered in hunting rounds like the .308 Winchester, and in 1962 Marlin entered the centerfire market with a version of it Levermatic, tailored for short centerfire rounds.
While there have been bigger marlin landed commercially and by recreational anglers not in accordance with IGFA rules, pictured in the following gallery are the leading big fish, officially speaking.
In 1910, John Barlow retired from his post leading the Ideal Reloading Tool Company, and Marlin bought Ideal, makers of the respected Ideal bullet moulds (Marlin also took over publication of the Ideal Handbooks, which they had been contributing to previously). As World War I ended, business faltered, and Marlin began to divest itself of the various other businesses that it had acquired during the war years (including the manufacture of ball bearings, roller bearings, radiators, automobiles, wire, bombs and high explosive projectiles).
The receiver was milled with a window on the side for ejection and a round window in the rear for bolt travel (instead of one big slot cut all the way through), leaving the rear sidewall of the receiver intact, resulting in a somewhat more solid, and stronger, receiver block.
They represent the ultimate benchmarks for anglers chasing the world's biggest fish. The 174-inch fish fell for a mackerel trolled in the once-legendary Black Marlin Boulevard off Cabo Blanco.

This would be the beginnings of the beloved Marlin 39A, giving rise to what, more or less, amounts to the longest continuously manufactured rifle in the world (production was briefly suspended from 1917-1922 for the War effort).
Micro-Groove rifling was the standard of the Marlin line from the mid-1950s up through the mid-1990s.
Along about 1997 or so, Micro-Groove rifling was dropped from the big-bore 336s and 1894s, and Marlin returned to 6-groove "Ballard" rifling for these guns.
Eddy Lawler of Peak Sportfishing Adventures went out on his 36-foot boat, the Black Marlin with a crew including angler Clay Hilbert on Monday and the team managed to haul a 1,089-pound blue marlin back to shore.
The marlin beat the previous Australian record for a blue marlin catch -- 996 pounds, which was set by Melanie Kisbee in 1999.
