This is for questions regarding shooting, reloading, build advice, etc.........no ethics discussions please

I'd like to know if you guys do any work on existing rifles. I.E. I have a Remington 700 Long Range and I think it shoots pretty good but I know it could be better. I had it shooting in the .8" range with factory HSM ammo and I'd like to know if there's anything you'd recommend doing to it to tighten those groups up and do you do stuff like that one someone else's rifle. Working up a load it shoots well is definitely in the plan, but what about things like bedding, trigger work, etc or do you only build rifles from the ground up? I'd also be interested in fluting the barrel and bolt just for that cool look. Curious to know your thoughts on that.

Thanks. This should be a good thread to follow.

Cool idea!  Dont really have any questions at the moment but always thirsty for knowledge feom guys like you.  Tagging along

From what I have seen on the Rem 700 LR Rifles, the following typically adds some improvement:
Skim Bed action and lug
Jewell Trigger
Brake and re-crown
Saddle cheekpiece

This is all stuff we can do.  I don't do any "accurizing" as some call it where they lap lugs, claim to true up the action and spin your barrel back on.  If your going to true the action, put a new barrel on it and really get the performance.


I wouldn't flute the barrel, a guy really wants to leave that up to the barrel manufacturers.  To big of a risk to have it go wrong.  Fluting the bolt is a pretty common thing however.  Its more cosmetic on Remingtons, but will reduce a little bit of weight.

How long does it take to build a rifle ? 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 ?

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?

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. 

Why do you recommend a jewel triggers over timney triggers on the Rem 700s?

Overall they are a better trigger as long as they are adjusted correctly.  A Jewell will always feels crisper than a Timney no matter what the weight of pull is.

I have a question for Travis.

Why the hell doesn't everyone just bite the bullet and buy a new RBros rifle?

JUST DO IT!!
