menial 1 Posted September 12, 2009 Report Share Posted September 12, 2009 I'm going to load some 105 A-max in my 22" 1in9 twist .243AI with Viht 160 starting with 42gr and working up in 1/2gr increments. Any thoughts or practical experience with this combination would be appreciated thanks. Pete. Link to comment Share on other sites More sharing options...
Andrew Posted September 13, 2009 Report Share Posted September 13, 2009 Common wisdom says that you should start with .243 data and work up. Since V-V's loading data lists either 41 or 43 grains for a maximum for the 243, you might want to back that off a bit. Be careful.~Andrew Link to comment Share on other sites More sharing options...
devilishdave Posted September 13, 2009 Report Share Posted September 13, 2009 I would be interestedf to here how you get on I am looking to load the same for a 22 inch barrel only differance is mine is 1:8 twist.

menial 1 Posted September 13, 2009 Author Report Share Posted September 13, 2009 Cheers Andrew, I've loaded up to 46gr with 85gr bullets and settled on 43.5gr as most accurate in .243 chamber. Looking through all the load data I can find, 42gr wouldn't seem too excessive as a starting point for this bullet choice. As always, everybody's opinion is valued and yours is no different. I realise that the Ackley version spikes quickly so will tread carefully, thankfully the temperatures are dropping as autumn rolls in and I'll not have the problems that higher temperatures seem to produce in summer.

devilishdave Posted February 4, 2010 Report Share Posted February 4, 2010 I have set up some rounds for load development but not got the chance to firing them yet. I loaded a small batch of 105 AMAX with 41 grains of 160 and straight away it is shooting 1/2 inch. I will let you know how I do with the other loads when I get some range time.

Foxshooter Posted February 5, 2010 Report Share Posted February 5, 2010 I dont suppose you have put that load over the chrono have you? I'm currently using Varget with 105gr AMax, only a light load, slow but accurate. Varget is getting expensive as hell and I already have N160 that I use with 210gr Bergers in the Winmag so a common powder would be really useful.

devilishdave Posted February 5, 2010 Report Share Posted February 5, 2010 I have not had a chance to run it over a chronograph yet. When I get some range time I should be able to run it through my mates chronograph. Dave Link to comment Share on other sites More sharing options...
shrek Posted February 6, 2010 Report Share Posted February 6, 2010 Hi guy, a good while since ive been on here, busy as hell latly!! Anyhow, just off the blower from the ill strucken mike norris the other day that my 243AI should be ready in a couple of weeks! I have ordered this rifle to shoot specifically 105 A-maxs, So its a 26" 1-8 twist chambered with a long throat, and a big badass muzzle break! I was thinking of using varget, or H414 but when i was with mike taking to him about it quickload said that reloader 22 will be the best powder for this combo! Hope all you guys are well and am llokin forward to seeing how you get on with your loads! Shrek Link to comment Share on other sites More sharing options...

I was running Viht N165 powder / Reloader 22 gave the same results / did try H1000 but that ran 100fps slower with no gain in accuracy!!! Stayed with the N165 because of accuracy and low ES........... All the best.............. RAY............................ Link to comment Share on other sites More sharing options...
menial 1 Posted February 9, 2010 Author Report Share Posted February 9, 2010 I haven't posted my findings with 105 A-max as my 1-8 Pacnor barrel turned out to have a tight bore and I couldn't even replicate standard .243 loads never mind bettering them. Sub .243 loads with various powders kept blowing primers and destroying brass so their seemed little point in attempting to find a suitable load. Had me scratching my head I can tell you. Now returned to original 1-10 barrel, set back and ackleyed and shooting 85gr Sierra varminters, load development is ongoing, suffice to say the original has exceeded the Pacnor without problem, just don't think it'll work with the 105's with the slower twist.
