Hi .

Is this the latest version ?

Reload in most cases, you benefit in lower costs and more accurate ammo. 
 

Im happy to reload 😀

Vortex can I ask , do you shoot in any competitions ?

I'm happiest shooting prone out to ...say 300 - 900 yards . Not sure if snap shooting or kneeling , sitting is for me 🤔

Are there comps for iron sights and just prone position ?

I have downloaded the CSR book , seems it's almost all position shooting ?

Thanks Bangbangman 😀

Chose the '17 - there's a massive choice of bullet for the 30-06 but very few 303.

Do shooters tend to reload or buy factory ?

P-14. There are some poor 1917's out there but P-14's tend to be very good.~Andrew

Thanks Andrew 🙂

I have the M1917 and honestly prefer the 30-06 cartridge to .303.  Bit more recoil out of it but it’s an accurate cartridge.

Shoot mine out to 800 and it’s still an accurate rifle for over 100 years old. 

Find yourself a nice one and you won’t regret it. 

Regards,

Vortex
 

A couple of friends have 30-06 , P14  and Martini Henry 577-450 . We are hoping to book Bisley later where I can have a shoot.  Thanks Vortex 🙂

Read the rules. You have to introduce yourself with your full name, then the Moderators will open the forum to you.

 

They aren't on 24/7 so you need to be patient.

Ok Roy , let's wait and see 😉

Your CSR questions would be better posted on www.csrshooter.co.uk

CSR FORUM

I have tried to join the CSR forum .

When I click on say ....forum index , nothing happens . Infact it seems I am registered but cannot communicate on the forum ?

Considering CSR , possibly historical .

The .303 versus the 30.06 ?

Prefer the handling of these rifles over the Lee Enfield , prefer the look , the only limitation (possibly) being the mag size .

Purely on reliability and accuracy is there a winner ?

I reload , would this point more to one calibre than the other ?

I am googling and reading , would appreciate the opinions of owners and those with hands on experience 😀

Agree I need to have a few dry runs . Will be interesting firing standing unsupported . Thank you 😀

Thanks Roy W .

I have fitted weights to the forend of my 6.5cm to help tame any muzzle flip . The scope is large mag and therefore heavy as I shoot prone and bench .

Assume it's better to keep the weight down for standing shots ( it's about 15lb ish at present ).

Thinking of attending a course at Bisley .

Checked and 6.5cm is ok for Practical Optics .

Anyone else using a 6.5cm ?

Have no choice have a 308 Savage 12 Ftr and a Bergara HMR in an MDT stock .

Used CFE223 from 45.5 to 47.5 .

Sierra 155g Hpbt .

CCIBR2 LRP .

The best group used 46.0g of powder .

Brass was swaged and if necessary lightly reamed . Primers seated fine a little deep , but within Sammi limits .

Tried to clone 7.62 GGG , with similar CBTO and similar COL . That's why I tried CFE spherical powder. 

Excellent results with 46.0g resulting in less than half moa group at 100yds . Should have been tighter , my fault . That's 4 shots .

If you join the GB Fclass league  https://gbfclass.com/  you'll be able to shoot 6th > 10th (all 5 days) All distances from 300 to 1000yds. Given you're traveling, you'd do well to book into the pavillion but you'll need to be quick as accommodation will be booked up very quickly. Oh, and about 300 + rds plus plenty of money for Beer food and more beer. 

Just joined , it all helps 🙂

Just measured the pockets of 20 cases using a vernier guage. Very consistent at .2065 , I have already swaged the brass.

Minimum is stated as .2085 .

Measuring this way is a little crude but it looks good 😀 , maybe a little tight. Better than to loose 🙂

Will still get a pin guage , when I have got my head around it 100%

I assume you are worried about finding oversize primer pockets in the head?  Maybe reusing brass that was primed with crimps?

As the maximum allowed tolerance is .210" I would suggest .211 (+1 thou) would be NO-GO,  ie testing for 'too loose'.  

I can't see what value a GO gauge is as the head arrives to you machined to tolerance so all you can expect to test for is oversize pockets.  Undersize would be highly unlikely.

You can buy a go - no go guage but everyone is out of stock .

Oh , and yes I am using swaged GGG crimped brass .

Makes sense to me at .211 for no go , too loose .

Not certain myself what purpose the , " go " , is for ?

As I have to specify both ends of the guage , think I will order .210 and .211 .

Thanks Popsbengo 🙂

I am looking at several companies that sell pin guages .

I can order a guage and specify my go - no go criteria .

At the risk of appearing thick 😄 , looking at the SAMMI diagram , what dimensions would be best ?

Should I use the .2085 as go and  .2100 as no go ? Or .2085 and .2101 ? Can't get my head around it 🥴

Here's an extract from SAAMI

Perfect , thank you 😀

Seems no stock in the UK 

If any of you good people own one could you please mic the go and no go diameters .

I believe the primer diameter is .210 .

Just watched Rosie in action.

Always fascinating to put a face to people's names .

The 155 , 175 and 185 you referred to in your previous post , were Sierra or Berger ?

Do you use a 30" or 32" barrel ?

Twist rate 1:12 ?

Really appreciate your help Richview , some sound advice and very useful figures 😀

Very interesting , thank you.

I understand the basics of reloading but there is sooo much more I have to learn.

Recommend any good books on the subject ?

Reloading all those NRA GGG cases is something I've been looking at. . . particularly looking to match it ballistically as it works for me and most of my club members up to 1000X.

The Sierra 155 bullet they were originally loaded with has become expensive and harder to source, so I've switched to the Lapua 155 Scenar, using N140. Basic load development just varying powder charges left me with reasonable accuracy, but nothing to get too excited about. But then I had some HPS cases primed and ready to go from a previous project so I tried them in place of the GGG ones. This seemed to significantly improve the performance of the load.

I haven't quantified this yet and I want to do some more direct comparisons to remove any other variables, but it has me questioning the quality of the GGG cases.

Triffid

 

I'm not certain if the 7.62 GGG cases are slightly heavier than Lapua . This would mean thicker brass and less capacity .

Have you reduced the powder load to compensate or just used standard loading data as normal ?

I wonder if the crimp removal has any effect on accuracy ?

Thanks Triffid , interesting observation .

I have now sourced 500 Sierra 155g (2155) Hpbt .

I intend to ladder test with various powders and seating measurements . 

I hope the GGG cases are good .

Please post your observations and I will do likewise 😀
