Re: 155gr bullet choice for 1:13 twist

I am not convinced that the higher twist rates often recommended today are better for competition shooting. You have to factor in that the bullet manufacturers, and many of the 'expert' writers have to give recommendations that cover all shooting conditions - including an Alaskan winter ! The curren...

Re: Given Current Component Availability...

I once built up a 22 PPC using 80 Grain Sierras. 1 in 8 inch twist. It was deadly accurate at 300y. For man years John Baxter used a 22-250 over all ranges and did very well with it but it was a serious barrel burner. A 223 run hard with 80 grainers is also a bit hard on barrels. Personally, I now w...

Re: Given Current Component Availability...

FWIW, I have seen the humble 6BR shoot out to 1200y. At this distance it was not really competitive with a good 6.5 nor a 7mm. But it is am impressive cartridge for what it is. Very good barrel life and low recoil if that is what you are after on a standard boltface. A possible correction for my rec...

Re: Given Current Component Availability...

I see some suggesting 30 cal either in 308W or something else. Definitely not a silly idea.

I would not be changing 7 SAUM to 308 just to keep shooting, however, unless you have a good source of SAUM brass. This thread is very much related to unavailability of components.

Re: Given Current Component Availability...

I have been recently playing with 6.5s again. Have used 6.5x47, 6.5 Creedmoor, 6.5x55, and Improved 6.5 x55 (Rogue) over the years. In the ultimate competition, none fully compete with the 7mms. They can all shoot very well - and all with unmodified cases. I have moved away from any Neck Turning and...

Re: Question for the Omark experts

Metals are malleable. Under sufficient pressure they flow which is a property of metals specific to the 'metallic' bond between their atoms. It is related to the fact that metals conduct electricity well which allows some of their electrons to easily relocate after flowing - thus still retaining str...

Re: Cleaning Rods. Coated or not

Some of my thoughts on cleaning rods. 1/ I believe that a hardened rod does less abrasive damage to a bore than a coated one. That is referring to damage due to friction in the bore. This is because it does not become ingrained with any hard abrasive such as flakes of Carbon. A hardened steel rod is...

Wildlife on Eco Friendly Rifle Ranges

Not sure where to put this. I have always thought we should push the fact that rifle ranges are quite eco friendly places and a haven to wildlife. I have attached a pic taken today. Some shooting was in progress a few lanes away and our visitor stayed put for some shots. There are a pair and they ne...

Re: 7mm SAUM Rechamber/Barrel Life

And when the US adopted the M17 (the US Enfield) in ww1 with British style rifling, there was much criticism. But it distinctly outlasted the US type rifling favored at the time. Perhaps not quite as accurate but more practical in a battle weapon. But I am not sure this has much bearing on a solidly...

Re: 7mm SAUM Rechamber/Barrel Life

I cannot answer the question because I have not run both my Saum barrels past 800 shots each. My policy has been to use a standard 284 back to 800y, then the Saum at 900, 1000y although enthusiasm did get the better of me the last Queens I shot and I used the Saum right through. I reckon that going ...

Re: Silver Mountain SOLO ET's

When we tested the Mareeba SM target (4 sensor type) in Mareeba there were no active adjacent shots. The log file was used to record reported positions of impacts on the target which eliminated transcription errors and reduced the complexity of the task to something doable. Remember, there were over...

Re: Scope Advise - 900yd MOA

There is no doubt that a NightForce BR can cover the range from 300 to 1000y - even to 1200y for Match Rifle. BUT it has to be mounted with great care to successfully span this range of distances. One extremely versatile option is to use Burris Signature Zee mounting rings which have fine adjustment...

Re: Barnard action

I do not have any method of measuring the diameter of the extractor groove to the precision we are considering but I must say that I found the rims that I measured had a constant diameter. Which does not exactly prove roundness but it does give confidence.

Re: Barnard action

Interesting thread. Since I have a box of unopened Lapua 6.5x55 brass, I decided to measure the rims. No idea what year of manufacture. I used a good micrometer since I trust it more than digital calipers which read about 1/2 thou more. I believe the micrometer more than the calipers which was confi...
