OK, Here's a list of "well reasoned" arguments as to why the .308 Marlin is a waste of time. All of these reasons were brought forth here or on another forum. They are, of course, paraphrased.
Now instead of long-winded whining, naysayers can just list the numbers identifying the reasons they don't like the .308 Marlin.
1. Should have used a .7mm-Waters.
2. Should have used a .7mmSTE.
3. Should have used a 7.62x39.
4. Should have used a .30-30AI.
5. Should have used a .300 Savage.
6. Should have used a .307 Win.
7. Should have used a.33 Win.
8. Should have used a.348 Win.
9. Should have used a JDJ cartridge.
10. Should have done a .50 Alaskan.
11. Should have used a 20” barrel.
12. Should have had a spiral magazine.
13. Should have used a blued, octagonal 24” barrel.
14. Forget the whole thing, it's D.O.A.
15. Forget the whole thing, I can't operate the lever.
16. Forget the whole thing, it's not readily available.
17. Forget the whole thing, its got that stupid safety.
18. Forget the whole thing, ammo will cost $40 a box.
19. Forget the whole thing, too much recoil and noise.
20. Forget the whole thing, I'd rather it was a .45-70 pump.
21. Forget the whole thing, I already have long range rifles.
22. Forget the whole thing, "i'm just too old & don't like change."
23. Forget the whole thing, it solves a problem that doesn't exist.
24. Forget the whole thing, just get a bolt gun in .308 Win or .30-06.
25. Forget the whole thing, just get a bolt gun for your sniping needs.
26. Forget the whole thing, if I want long range I’ll get a Sharps or Ballard.
27. Forget the whole thing, someone will load it with regular spitzer bullets.
28. Forget the whole thing, the .308 Marlin has not passed the test of time.
29. Forget the whole thing, leverguns weren't intended to have such capabilities.
30. Forget the whole thing, it won't do anything a .30-30 at the same pressures won't do.
31. Forget the whole thing, if you buy one you are doomed to buying factory ammo forever.
32. Forget the whole thing, "because I am too old to realize a gain in performance and value of this new caliber."
33. Forget the whole thing, just get a Winnie in .307 or a Savage 99 or a Browning BLR or a Winnie/Browning 1895.
34. Forget the whole thing, new Marlin rifles have a "cheapness" about them that precludes any interest in them as a whole.
35. Forget the whole thing, the .308 Marlin Express "would NOT make a good Black Bear caliber. Unless you are shooting Cubs."
36. It must be a lie, you can't get .307 velocities from a smaller case withhout pressures higher than a .307.
37. Should have just manufactured the Savage 99 under license.
38. Why reinvent the wheel (.307 and Savage .300)?
39. The ammo will cost too much.
40. You can’t match factory ballistics.
41. You can’t even match factory muzzle velocity.
42. You can't get the brass.
43. You can’t get the bullets.
44. You can't get bullets in the same weight.
45. You can't get the powder.
46. You can't get the dies.
47. The powders aren’t available so its really just a .30-30 XLR.
48. Don’t like the way the XLR looks.
49. Don't like Marlins, why should I like this one?
50. The .30-30 can kill at 200 yards and beyond – what’s the point?
51. The XLR will cost too much.
52. 2” groups at 200 yards is not match-grade ammo.
53. Its just a scam by greedy companies to get your money.
54. Marlin should have spent their “finite resources” to improve the accuracy of ALL their rifles.
55. Marlin should have spent their “finite resources” to introduce novel/better open sights.
56. Marlin should have spent their “finite resources” to make periodic runs of guns chambered for obsolete cartridges.
57. Marlin should have spent their “finite resources” to introduce a ‘tactical’ 1894.
58. Marlin should have spent their “finite resources” to introduce a pump-action .357/.44/.45.
59. Sharp-pointed bullets don’t offer anything over RN or FN bullets, so what’s the point.
60. Old timers figured if they could hit a piece of typing paper they were sighted in, why does Marlin need to be different?
61. Most game is taken at 100-150 yards tops, why do we need something that reaches further?
62. The .30-30 has taken Africa’s Big Five, why do we need anything else?
63. You don’t need the extra energy the .308 Marlin provides as the .30-30 can kill a 200-pound deer at 230 yards.
64. You don’t need the extra trajectory the .308 Marlin provides as the .30-30 can kill a 200-pound deer at 230 yards.
65. The extra range of the .308 Marlin will just encourage people to take shots at ranges they shouldn’t attempt.
66. I won’t buy a .308 Marlin because Marlin didn’t answer a letter I wrote them.
67. The trend toward modernizing traditional designs is a waste of time – it can’t be done.
68. You can’t use the .308 Marlin’s extra range without a scope, and scoping a levergun is just wrong.
69. I won’t buy a .308 Marlin because Marlin won’t build rifles chambered for the obsolete cartridges I want – and I know two other guys that want them, too!
