1 in 14 is supposed to stabilize a 600gr Barnes original at 900fps. Let me know if you find one. I know it will stabilize a 530gr bullet in a 7" barrel.

Alleycat - good news on the heavy projectiles stabilizing. What velocity are you getting with the 530s?

21.5 grs of VV N110 gets me about 1050 fps
22.0 grs of VV N110 gets me in the high 1080s

Zero pressure signs on the brass. Cases are not thrown far from the gun. I was a little worried about a 7" gun, but so far it runs 100% with subs.

May or may not produce a bit more velocity with a 16 inch barrel but it is a great starting point - especially for 550 grains.

Thanks.

The good news on my front is the Lee dies have arrived, the barrel should be not far away and the reamer looks to be here in the next week or so.

EDIT: I was wrong - the reamer arrived today!

Im loading 32 gr of 296. OAL-2.20. IIRC velocity was around 1825 fps. groups avg 1.5" at 100 yds from the bench with a 1x4 Millett DMS. I hope to test on a deer this month. YMMV.

Any update on the progress of this combo? I had been looking at doing something subsonic in .510 to launch A-Max's; but since having seen pics of the big beautiful Lehigh's loaded up in 458's -I think this might be the way I go. If they would feed from a Savage centerfeed Long action that would seal the deal.

The barrel's in ,7 groove Rock Creek but beyond that ....There hasnt been enough time.

Lou Boyd can probably tell you about the loaded length and ballistics. My trying this round a third time was inspired by his pics.
I dont doubt you'd be able to seat the bullet a little deep if getting it to feed due to excess OAL is an issue.

My barrel just arrived today - straight cylinder Douglas blank - enormous and my smith is going to have fun slimming it down.

What length now is the question for a bolt action. I'm thinking 18 inches to start with.
