7mm Rem Mag Help

[lcq01]

I downloaded one from IMR and it lists 66gr with a 175gr. @2910. That is so radically different it must be a misprint
I went off the imr downloadable manual. It lists loads for 160 pts & af's of 7828 @ 66.0 & 66.5 @2940 from a 24" barrel. Every other source was more conservative.

I haven't been in the right place at the.right time to get retumbo or H1000 yet. Though a lot of people suggest them.

Imr don't meter well but seems to have a predictable temp sensitivity and fairly wide accuracy node.

Well I wonder what Nosler is smoking to get 3008 out of 64gr IMR7828 because at 63 I got 2700 and the cases were smoked at 64.5 2803 and not even a flattened primer. By my back of the envelope calculation I will be close to your 66gr to squeak out 2900. so far it looks more promising for the W-780

Best Bullet I've used out of a Savage 7mm mag 24in barrel is the Hornady 162gr SST. Shot dime size groups at 100 yards.
