Great idea for a thread!
Where is the best/correct place to measure sight height (center bore to center scope) when using a base with 20 MOA built into the base? And, how much does it really matter?

Always wondered about the test targets builders show ?When you show test targets are those factory ammo or reloads , if reloads do all your rifles like the same recipe or do you work up a load for each individual rifle ?

With the machining, stock fitting, bedding, coating, etc....there is usually about approx. 12-14hr per rifle.
Most of my test targets are with handloads, but some I use factory ammo with as well. A lot of the 6.5 Creedmoors, 260's, 280AI's, and 338 Lapua's, I will use factory ammo with.
Now, here is the part that bugs me about other builders. That charge they bill for "load development"....its a complete BS deal. Just a way to get a little extra money for actually shooting the rifle. The load recipe never changes from rifle to rifle. In the last 10yrs the only thing that has changed is that I had to back down my charge weight on my 7 Mag load since Retumbo became a little faster burn rate in the last couple years. Other than that, every rifle that I build runs the same loads and they are very well proven for accuracy.

Here is an easy way to do it. Lets use the following scenario:
You barrel shank is 1.25" diameter, so half that is: .625"
Your scope is a 30mm tube or 1.181", so half that is: .5905"
The distance from the top of your barrel at the recoil lug area to the bottom of the 30mm tube section is: .729"
Add those all together and you come up with 1.9445", round that to 1.95" and put that into you ballistic app. A slight difference in height won't make that much difference, but if you leave it at the default number of 1.5" of most apps, you would be a bit off at distance using this example.

tagging in. I have a Rem 700 LR 300rum that may need your love. :chuckle: :tup:
Why do you recommend a jewel triggers over timney triggers on the Rem 700s?
