"Long barrels are for getting inefficient old school magnum cartriges full of slow burning powder up to speed"
The Grendel runs about the same hunting energy as a .243win only it runs slower with a heavier bullet. As long as you use light jacketed varmint/tipped target bullets it will kill just like a .243win. I have dropped animals with my 10.5" barrel to a little over 500m however the Grendel really is a 300m cartridge unless you really trust yourself to hit a 6" target out at 500 consistently.
Know your rifle, know your ballistics and know your limits.

Good effort on the goats, another customer just sent some pics of his first deer with his Elude custom 6.5 Grendel too.

What powder are you using to get 2500 from 14.5 inch. I can't even get that from my factory length howa

ADI BM8208 is the grendels best friend.

Time for me to start reloading for the Grendel with BM8208 then! I have been hesitant chopping as I am only getting 2470fps out of the 22in I have! If I can get better than that out of 14.5in, then why not!

Yup been using that. 27.5 grains for 2450. Maybe it's my barrel

My 14.5" trueflight barrel got 2550fps with 123gr Lapua scenars with 27.8gr of 8208.

You might find youd get more speed with a slower powder like Aliant power pro varmint in that longer barrel. The 8208 is best for short barrels. I run 28gr with 120gr eldms and 120gr targex in 12.5" the factory howa barrels I've tested which gets about 2320fps

@Wingman did you go to Talley extended rings or just standard? You had previously mentioned that you’d fitted Talley ultra-lows. Not wanting to put a rail on mine but want to make sure the scope will push forward enough.
Having just said that, I guess I’ll have to consider the rail option if I run a red dot and then will need another set of rings for a scope for ease of interchangeability.

Just depends what suppliers have in stock.. stock levels seem low or unavailable on many products

I hear what you’re saying. My first 30mm tube scope, which is a lot more common nowadays, is making it harder. The one downside of living here is the inability to just pop down to the shop to browse. Have to do as much research online as I can then get on the phone to check for stock. Hopefully I’ll get to Invers next week and pick up what I need but I try to always have a backup plan.

ah yes but what will you manage with the 22 inch????

@Wingman do you think you could blob a r93 “bedding block action” in one of these if I provided the action?

I'm not sure you have even seen the size of a howa mini action? NO other action will fit this chassis, it was designed specifically for the Howa mini alone.
A custom one off chassis design and CNC would cost you about 15k

I found a set of 30mm lows in my draw from when I ordered a bunch to find out the best set up for mine. Went with the ultra lows but they are too low for most people.
These are available if they get you running

for future clarity purposes..will you please post photo of one in ..exploded view as it was (NO NO DONT BLOW ONE UP) Just action out beside stock bottom metal/mag below it sort of deal and bolts etc sort of near enough to in place.... might save any more questions like one above or someone trying to Bubbafi chassis to work on something it wont fit.
