I've had a Grendel since it the Howa Mini was launched and its a sweet round. Am playing with the 123gr Hornady Black ammo at the moment and it reasonably accurate, thou not overly fast at around 2600fps.

Ive just bought some 100gr TTSX and a bottle of 8208 so pretty keen to see if I can stock it up to around 2900fps or so.....

And where the Grendel really shines is the lack of recoil, SWFA, Ive had 6.5 swede's and 260 rems and the Grendel is miles in front hen you stick it out the ute window.



Hi Bill

I don't think I actually chronographed the 95 Vmax out of the Creedmoor. I have kind of switch over to using the 90gr TNT Speer hollow point. Mainly because I can get them for 40 cents each. I have shoot a few out Grendel and Creedmoor.

My load for the Grendel was 31.0gr of 8208 in a Lapua case

Creedmoor was 42.5gr 2208 in Hornady case. I had been using 8208 with the lighter bullets. But I think 2208 seemed better for me. My Creedmoor does have 26inch barrel. I am really actually quite interested to see how fast the 90gr TNT are travelling I reckon they would be spinning quite fast with 1-8 twist.

Thanks for your post it has got me keen to get the Grendel out and do some shooting. I'll strap the chronograph on and post up some numbers.

Hmmm the 90gr TNT weren't going as fast as I expected. The Creedmoor was doing 3180fps with 42.5gr Ar2208 and the Grendel was doing 2800fps with 31gr 8208. I was expecting the Creedmoor to be a bit faster and I was also expecting the Grendel to be closer to 2900fps. But the Grendel is still fairly impressive within 300 fps (nearly 400 in this case) but 10 grains less powder.

To try something different I tried ar2207 in the Grendel (ADI manual has data) 25gr ar2207 doing 2700fps with respectable accuracy. Will test further.
