Howa Mini Rifles, Builds, and Upgrades

Same ammo you had loaded for previous barrel, or did you make a change?

Same ammo. I could tweak it and probably will later but it’s shooting pretty good.

Are these the factory 90 cx? If so, where do you find them in stock?

Had the chance to chrono factory 80 ELD-VT last week out of the 16” barrel. 10 shots averaged 2735 fps.

The 108s averaged 2487 the same day.

Taking the chrono values from the last two range sessions and comparing them to Hornady box values, this 16 inch barrel is shooting just under 91% of the box speed. I’d expect to get around 2700 fps from the factory 90 cx.

90gr ELD-X over 28gr of 8208. Im getting 2850 average out of the factory 22" barrel.

At a very rough calculation, I think you could expect around 2580 fps with the same load through a 16" barrel, give or take.

Oof. I've found some posts with guys running custom shorter barrels on their Howa's and still getting pretty good velocity. I may have to look at a custom barrel at some point.
