22lr reamer

[Matt_3479]

Looking to test a fast twist for 300-500 yard 22lr. Rifle will be used for distance testing as well as prs 100-400 yards. Main ammo being used will be sk rifle match as that’s what I’m shooting now. Center x is my back up ammo normally.

what reamer should I be looking for for this barrel?

Jasmine at JGS can send you their 22lr comparison chart. There are several reamers you can choose from.

Matt, is that ammo suitable for long range?

Matt, is that ammo suitable for long range?

We’ve had extremely good results with Center x and rifle match at 300 and 350 with the 1:16 twists. Didn’t get set up in time last year to test 400+ but did have some fun at 400-450 ish. This season we’ve set up a little differently where we can test a little better at 300-500 yards. I’ll be sticking with this ammo as I have a good supply and shoot it in the 1:16’s for prs with great results. Seeing as the furthest targets we have are around 400+/- 20 yards in most of the match’s I was hoping to see if the 1:12 and 1:10 will result better between 100-400 yards.

.22 Nevius. It was developed by Kevin Nevius for Lapua ammunition.

Whats the best for eley like match and tenex with the eps bullet?

1. Read Calfee's book: The43 Art of Rimfire accuracy.
Call Mark Penrod, He can probably tell you what reamer to use with said ammo.
PTG list about 25 different .22LR reamers. Talk to Dave Kiff, He maybe able to help you out on a reamer.
For a match reamer, straight case with about a 2* lead will work with most .22 target ammo. Set about .041-.0425 head space.

I have read that book plus every article he wrote on benchrest.com and in precision shooting. thats why id like to have the whole collection of the calfee reamers plus a nevius. I just know as soon as i mention that name i gotta put a flame suit on. Id like to meet him and learn a few things

@Dusty Stevens
Have you been on rimfirecentral.com? Those guys are hardcores for the most part. Might find some useful information.

 

[CJ6]

Dusty, Checkout Benchrest Central...Quite a few RF/BR Smiths on there.

Dusty,

There are many reamers and there has been a certain amount of success with most of them.

How the reamer is used is probably more important than the reamer itself. Especially how the chamber is finished.

It has been said that a chamber will finish itself with enough shooting. There have been many cases where a rifle didn't shoot well until it had many bricks of ammo shot through it.

Finishing the chamber properly will allow the rifle to shoot well nearly from the start.

Although there are some companies that have labeled reamers as "Calfee reamers" Calfee really has only one reamer.

It is a .225 straight sided, 2 degree reamer.

Many very good shooting rifles have been chambered with this reamer.

I can say from personal experience a chamber cut with this reamer will shoot Lapua as well as Eley, both round nose, and EPS.

Note: headspace will be different between Lapua and Eley.

So whats the difference in headspace between lapua and eley numbers wise?

Im guessing all those calfee reamers on that sheet above are bore size modifications from the original .225?

Ive used a 5.45 1/7.8 twist barrel and a 52D reamer for a long range 22 a few years ago . It was a experiment in squeeze bore and fast twist for the 22 lr .
the 52D reamer needed a little modification but everything else went well . Recovered bullets are a little longer than usual of course and the accuracy was depending on ammo , like any other 22 . All testing was at 300 yds which was the longest available at our range .

.22 Nevius. It was developed by Kevin Nevius for Lapua ammunition.

100% agree, but it is not just the reamer how the chamber depth is set is the most important. Kevin recommends 0.075 stick out of a live round so you get 0.030 engraving on the first band. something I learned recently; a tighter bore dimension will change how deep you need to go to get the proper engraving.

So whats the difference in headspace between lapua and eley numbers wise?

On average Lapua has a little thicker rim thickness than Eley. Lapua normally about .40.5 to .41.5 and Eley .38.5 to .39.5. If you set up your headspace a little tight you may feel it when closing the bolt on some Lapua rounds. In my experience tight headspace isn't good for accuracy.

Back in the day I shot Time Precision rifles. They had adjustable headspace by using shims between the barrel and action face.

I would sort my ammo by rim thickness. Using the spacers, I could ensure my headspace stayed constant in all my sorted groups regardless of the ammo rim thickness. I also sorted by weight, as well as run out, but that is another story.

Was all this effort worth it? Well, I did learn a few things and one of them was you will have more fliers with headspace being a little tight that you will with it a little loose. In plain terms headspace of .044 is much better than .041.5. Many smiths shoot for .043.

PTG sells a 22 EPS reamer.

 

[VLNBYR]

Id like to meet him and learn a few things

I know of very successful Calfee shooters who were never able to meet him or talk with him in person. Probably not going to happen.

 

[David Conder]

Where can you get the barrel shims if you can help thanks
