Creedmoor question

[Rookie]

I really wanted to use 95 grain vmax for coyotes, but the accuracy wasn't better than my grendel. It was shooting 2 1/2 inch groups at 200 yards. I checked zero with 129 grain bullets, and the group tightened up to 1 3/8 at 200 yards.

I noticed that the 129 grain are about 1/8 inch longer than the 95 grain. Could this be why there's an accuracy difference?

What load were you using? How much workup did you do?

A 95 over Varget or XBR should be nice coyote medicine from a 6.5 Creedmoor.

Factory loads...

Hornady Varmint Express.

If you're not planning on reloading, I'd give the heavier offerings a shot too. They might be the ticket in factory loadings for your gun. I'll bet there is a load that will shoot those 95 grainers sub moa but finding it may require some experimentation. You just want 'em dead, right? Don't think any of these loads are real fur friendly, are they?

To answer the original question, it's possible the length difference affects accuracy, but more likely, the weight difference affects bbl harmonics in a way that favors the heavier bullet.

I'm wanting as flat as possible.

143gr ELD X might be the ticket for your rifle.

2nd on the 143gr Eld X. I have an RPR in 6.5 creed and my 3 shot groups can typically be covered with a quarter if not tighter at 100 yards. That being said, those were hand loads. I have had quite a bit of luck with the sellier bellot 140gr fmj's as well. I typically used them as plinking rounds, but the inherent accuracy of the RPR surprised me a little. Not quite as tight as hand loads, obviously, but plenty for taking coyotes within 200 yards.

.243 and some 55 gr Noslers?

You say you want flat as possible, but your first post was complaining about accuracy. If you're stuck with factory ammo, you rarely get to have the best of all worlds. Handloading is the real answer to your question.
