Re: 155gr bullet choice for 1:13 twist

Thank you all for your input. Selecting twist rate is a compromise which does lead to having different barrels for short and longs if you wanted to optimise the twist. I've noticed that the berger have revised their website twist recommendations a few times but if you go to their twist calculator an...

Re: 155gr bullet choice for 1:13 twist

Thanks argh, scott/r, williada, for you input. Price is a consideration in this case. Incidently I have a stash of 155 hybrids and 1:10 barrels :D :D :D but just looking to not "waste" the 1:13. So from the advice it looks like the #2156 SMK would be the best choice with the 155.5 HBC a cl...

Re: 155gr bullet choice for 1:13 twist

Thanks Alan,
While they will all stabilise, I know the berger hybrids prefer at least 1:11 & berger's twist calculator recommends 1:12 for the 155.5 fullbore.

What's the experience with the hbc 155.5?

Thanks
Peter

155gr bullet choice for 1:13 twist

Hi All,
I've got a couple of 1:13 twist barrels with plenty of life left in them that came with a rifle I brought. I'm thinking of using them for practice and club days. What 155gr bullet would people recommend. I know the #2155 SMK will work but is there anything else?

Appreciate any advice.
Peter

Re: The Future

This is great discussion, I hope it translates to the beginning of meaningful change. If I may add my perspective as someone who has shot at grass roots level in several countries other than Australia. It has been mentioned in a previous post that the strictness of Australian gun laws encourages par...

Re: importing into QLD

Thanks Roger, I should have been more specific in that I'm looking to import from outside of Australia.

importing into QLD

Hi all,
I would like chat with someone offline about the details of importing firearms and related stuff into QLD. I'm familiar with the forms and process but want to chat with someone with recent experience so that I do and say the right things and avoid complications.

Thanks

Re: Does a plastic tip , mean I can get away with a slower twist ?

Graham,
The JBM screen shot you posted jogged my memory about a third paper from Courtney on twist, so I did some digging found it and a spreadsheet to calculate it. I haven't verified the spreadsheet.

Enjoy!

Re: Does a plastic tip , mean I can get away with a slower twist ?

Graham, FWIW, I've attached some work on modifying the Miller stability formula for plastic tipped bullets by Michael Courtney & Don Miller. So, if you're now known as the Gman does this mean that where you're standing is called the Gspot? :-k Sorry couldn't help myself :lol: I really tried! !Pe...

Re: Silver Mountain SOLO ET's

Thank you Daniel for that detail.

Am I correct in concluding that all external acoustic targets are going to be susecptable to lost shots due to the "deadtime" / "recovery time" inherent in the sensors?

Re: Using CLR to clean barrels

I posted this in the thread about carbon removal: I happened to have a rifle sitting on the work bench that I was about to use JB to remove a carbon ring so I gave CLR a go. Half a dozen strokes with a wet patch, let it sit for 30min, clean out and carbon ring gone. I should have taken photos from t...

Re: LabRadar Bluetooth app now available

One little thing I noticed was that the Labradar gave no indication that the firmware had been updated other than new firmware numbers on the boot screen and the firmware files deleted from the SD card.
