[Mschroeder40]

First I want to say a really big thanks to Steve at Hammer! He answered my phone call and discussed load data and was very humble and honest about load data and bullets. It is always a breath of fresh air to speak with people like Steve that are business owners and an outstanding person that doesn't let success get in the way of being personal with customers. I will be a customer for life! They also offer Veteran discounts, and it is much appreciated! Thanks Steve for great products and service!

Here is some load data for the 6.5 prc with 124hh and N555

Hope to see chrono results soon, as well as trajectory testing (if feasible) to determine/verify BC of that projectile. Nice results so far! Pardon if I'm ignorant but do I assume correctly that the stated 1.75 twist indicates rifling pitch is 1 rotation/7.5" bbl travel? Regards

I had better luck with n560. Got up to 3500fps with the absolute, at that speed it hammers

 

[Mschroeder40]

7.5 twist correct.

I only had n555 and n568 available. N555 seemed best with this weight.

I will work on the chronograph numbers and verify out to 600. Vihtavuori Load data states 52.5 pushes a 130gr at 3022fps. So we should be close to 3400fps but need to verify.

568 worked with the 156 Berger

 

[Mschroeder40]

I will try that with 156's I have several hundred of em.

 

[Mschroeder40]

I got some numbers today for the n555. 3 shot
3149, 3145, 3170
This is out of a 22in barrel
I'm going to order some n560 and try it.

Would you say the BC Hammer lists for the 124 is fairly accurate?

 

[Mschroeder40]

I would say yes.
