My $.02: I put a Shilen featherweight on my Model 7 action & cut it to 18 inches. 20 grain pills can run 4000, 25 grain pills at 3800. Accuracy @100 is 1/2 inch. I doubt you'll get much more velocity out of anything longer than 22". A 100 yd. bench gun 17 fireball at longer than 24, IMHO is asking for vertical string problems. That powder is long gone burned in about 12 inches.

Thanks for all of the replies
You've really helped me out Brad |

This cartridge only burns about 19gr powder and 22-23" of barrel is plenty. A longer barrel won't give much if anything more. It's not loud enough to worry about getting the muzzle blast out further away from you. There's no recoil/muzzle jump so the barrel doesn't have to be a big heavy thing. I've had the MIV on Rem and Sako actions. With the small Sako you can have a varmint or light varmint weight barrel and the gun will shoot beautifully off bags yet still handle comfortably in/out of a truck or carrying.

Here are my results for what it's worth. I have both a Remington model 7 predator (22" barrel) and a 700 with a 24" barrel. Using 25 gr Hornady HP and I believe 18gr of H322 I get 3850 fps from the 24" barrel and 3750 from the 22" barrel. So for me 2" of barrel length is worth 100 fps. I believe this would vary by the particular barrel to some extent.

Just curious as I have 17 Fireball and was hoping for a bit more in terms of barrel life. Last edited by Bad Wolf; 09-18-2014 at 12:47 PM. |

As for the barrel life on my rifle I let the groups determine when that happens. That 2600 rounds was spent in PD patches, I've seen some that get more and some less. Barrels are consumables, when they are worn out they let you know. On mine the throat had washed out so it was an easy fix to extend the life of the barrel.

Barrel 17FB
I have a 24" sporter and a 26" heavy barrel custom
Both work well and are very accurate |

If I had a 1000 22" barrels and 1000 24" barrels and compared the average velocities I may be "close" to making an apples to apples comparison. I don't have that access as I'm sure no one here likely does unless a barrel manufacturer themselves do so such a study. From what I have read in different articles is on AVERAGE for the AVERAGE barrel, 1" of barrel loss account for about 25-50 fps of velocity loss. Whether anyone believes that or not is up to them. I'm sure this also varies by the cartridge. It approximates what I have found in MY rifles only. So take it with a grain of salt I suppose. Like I stated previously this is all just conjecture anyways. |

Pretty sure mine is a 26" but I need to check again.
Shilen select 9 twist that gives me 3800 FPS with H335. |
