7mm sherman max

Proof 24" 8 twist, new barrel. I've also got N570, RL23, H4831sc and H4350 to work with.

Definitely try H4350. Not sure where the others are in terms of burn rate but see would be good.

For the Cayuga shooters, how has the terminal performance been at distances further than 600yds? The BC is pretty impressive in the 170. @codyadams, more info please. How is the long range performance?

enough said!
Try some 23 and if that doesn't change things, fill the case with N570 and tamp it down

Rich,

Is there a specific bullet weight range 23 is optimal for?

I'm shooting the 195s using 26 but also have 23. Shooting the 140 monos using H4350.

23 should work pretty well for 150-180

Refer to this thread. There is some garbage in the beginning, the actual on game data starts on page 4, post 50 -

Anyone using PVA Cayuga bullets?

How have you found the Cayuga projos relative to the Badlands Gen II for pressuring up? I run the 7mm 150 Badlands Gen 2's at 3,711 fps. Could I expect the Cayuga 151's come out about the same? From what I have found, the Cayuga's are more similar to a standard lead core bullet, I have actually...

So far they have been good, but I generally try to reserve any solid opinions until I have at least 10-15 critters on the ground with a specific bullet.

Thank you! That was a lot to read!. Good stuff. I have some badlands 150's I want to try in my 7 Max. I'll go through that round before I look to the Cayuga's. Thanks again.

Tried the RL23 this afternoon, ran a pressure test from 60.0 grains at 2824 fps up to 66.0 grains at 3122 with no signs of pressure. RL23 is pretty light weight to volume compared to others, I'm out of room at 66, 67 puts me into the neck. Only node was between 62 and 63 at 2976 and 2996 respectively. I may give N570 a try. How about H4831SC?

don't think you would gain anything with 4831 over 23, but you could try. Based on your 23 results, Id try H100v.
Also RL17 and N550 might do the trick.

 

[Rhovee]

You can fit more 4831sc in a case compared to RL23.

 

[LiveToHunt7]

According to the burn rate chart, RL23 seems to be on par with H1000.

RL17 would be a close comparison to H4350. 4831sc would be in the middle. N570 is further down, below Retumbo.

4831sc might be the ticket.

Rl23 vs H1000 slight speed edge to 23 but temp (especially heat sensitivity) goes to H1000 if that is a concern.
RL 17 is wicked for heat sensitivity, again if that is a factor then
H4350 & H4831 are your go to powders

I agree, I'm just not sure you'll gain velocity though?
worth a try.

I agree. Not sure if that's a factor he's considering, but H4350 is #1 in temp stability as far as I know.

Most Hodgdon powders are.
