I also recommend the 129 ABLR based on my experiences with that bullet compared to the others recommended. I don't believe in using bullets weighing more than 130gr in the Grendel. The inherent SD of 6.5 bullets allows them to penetrate better than other calibers when weights are equal. I wish someone would make a 100gr PSP similar to but cheaper than the 100gr Partitions, which I run at 2890fps in my Howa Mini.
Match the velocity to what the bullet's parameters are....
but in my Grendel, in 100 grain Bullets I've used.
1. 100 SP Hornady. Discontinued, but I'm setting on about 2,000 of them
2. 100 HP Sierra
3. 100 gr Ballistic Tips.
4. 105 SMP Partition from Nosler, factory seconds, but sold to some Euro Manufacturer RMS I believe.
No flies on some of the less than 100 grain bullets
1. 90 gr Speer TNT
2. 95 grain V Max
3. 85 gr HP Sierra ( Discountinued, but bought about 1500 on close out )
4. 90 gr Nosler Varmaggeddon
Shot all of these out of the Grendel ( Ruger Predator is the platform )
Have taken blacktails with each of these bullets out of a 260 Remington, loaded in the MV range of the bullet to work well on deer, out to 200 yds or so.
