| I have a 18" White Oak Armament Barrel that is very picky about bullet length. I have noticed when using shorter bullets such as 55 grainers (I don't have one to measure for a length at the moment) accuracy drops significantly. If I stay up in the 77 grain match area (which is generally about .987 inches) I get groups that are just over 1 inch at 100 yards. My question is this: Is there a resource out there for bullet length? I have started my own, however, it would be easier when buying bullets or comparing them to have the length available to me for decisions. |

I noticed the JBM site does not have the Hornady FTX .35 cal (remington) bullet length listed. I just bought a hundred. Let me know if you need the bullet length.
Also, Quickload Bullet Reference files carries bullet length on all their bullets from 60 files of 60 brands/vendors of bullets and a myriad of bullet configurations and calibers from each vendor. |

Thanks so much. I appreciate it!! What twist is your barrel, 1:7", 1:8"? You're probably going to want to know ogive length, which that list doesn't give, as it's overall length. Chris The twist is a true 1:7 and its very picky about length. The more of the body we'll call it (from the shoulder of the ogive back to the tail) there is the better. The barrel is a White Oak Armament 18" SPR barrel with midlength gas system. While a very accurate barrel for 75-77gr projectiles, conventional bullets (copper jacket on lead core) that are shorter (forgive me for not having a good length to say where accuracy starts to drop) don't group well. In all honesty, because of my hectic schedule, I have concentrated on loading bullets that I know will group well instead of bullets that won't to find the point where accuracy improves in relationship to bullet weight. I would like to find a lighter bullet for closer in hunting purposes as I'd rather not use a 75gr Hornady match for this. Also, I haven't chrony'd any of my loads (lack of chrony) but acquiring a chrony is in the works. |

I've got a 20" Bushmaster .gov profile 1:7", which I wanted for shooting the longer, heavier bullets with their better BCs. Your barrel just doesn't like the lighter bullets, which will necessarily be 'shorter'. If your barrel likes a longer bearing surfaces, you might want to look at the more traditional hunting bullets like the Nosler Partitions (as an example) with their longer bearing surfaces. The BC won't be as good as a target grade bullet, but you're talking about closer ranges. If you had the Hornady/Stoney Point bullet comparators, you could dial it in a bit more. Chris |
