rimfire Tuner / Harrell

[Tomiboy]

Hey @Jadams, I'll give you some numbers to chew on.

Here's the rifle:

Here's how it shoots:


The barrel is exactly 26" long, and the end of the harrell tuner to the muzzle is 3.553"

I use my own method, which is loosely modeled on the hopewell method. I'm curious how close you find it to the purdy.

Are you using a Harrel's tuner? If so what number are you on?
Thanks!

Glad to see Orkan pull this up so i don't have to dig for it. I have the same setup, yet to get to a range. Just checked my tuner set to his dimensions with 1" extension, looks like 243 or close.

 

[Tomiboy]

Where doe one get this 1" extension you speak of?

 

[Arkansan]

I got mine from Harrells.

Functionally speaking it is more correct to refer and think of this as a weight rather than as an extension.

There are both types, but other than a bloop tube I don't have a link to a 1" all Aluminum one at hand.

There are both types but I believe the one in the photo is sold by Harrell as a weight.

Harrel's has (2) 1" long ones and (1) 1/2" long one. One of the 1" is steel and 7oz and one is aluminum and 3 oz

steel or aluminum?

 

[Tomiboy]

The 1/2" is steel and is 5 oz

When I bought my Harrell weights I got a set of three, two steel with both male and female threads and one aluminum with male only.

With the barrel profiles we use, we start with the 7oz., 1 inch long weight.

[Tomiboy]

Todde is that for a 26" barrel? What profile?

 

[todde]

Typically in the 25 inch and .850-.900 straight profile.
Todd

 

[Tomiboy]

So what would you think I would need for a 26" with a .90 straight profile?

 

[todde]

I would start with the 7oz weight and start tuner at 50. I would expect a tune to be found +or - 20 clicks.

Can EC barrel tuners be used for rimfire calibers?

yes they can..Ive had several on barrels of several calibers for a few years. They improved all but one.It shot so good that anything I used hurt it.
