I'm running my 105s with 4895. What load are you running 105s/H4350, and what velocity are you getting?
Sorry for the confusion. Thought you were responding with respect to the 6 BRA here.
Oh, sorry I have mentioned too many br-based cartridges in this thread.
So velocity with H4350 is usually the same as what you'd get with varget... in all of these little guys. In the case of 6mm and 105's, I'm loading from 31gr in a straight BR to 34gr in a Dasher. So that gives you some idea of the window. I run slow and stable in most everything, so I'm only running 2925 in my Dasher. I'm not one of the people that advocates high nodes.
have you considered the 6mm ARC? It shoots flat..I shoot it mostly at 600 yards but have rang steel at 1000 yds & 1150 yds. The 1200 target was down that day.
I agree with almost everything you have said except this. I have been through 4 cheap button rifled, but hand lapped 243AI barrels. I ran a heavy charge of H1000 in all of them. I ran 105s in the 3150 range and 115 dtacs in the 3050 range. All barrels lasted 2000 rounds before shooting bigger than 3" for 5 shots at 600 yds consistently. Of course I am not a world class shooter and had groups bigger, but for the most part the gun would hold half moa in calm conditions with very little effort. 3 of the barrels gave up at around 2500 rds and the last at around 2000 rds. Load development to get to this point and stay there was sort of a bitch. Over time I streamlined the process and got better results. I never got the results I get with 6br based cartridges. See below.6xc isn't flatter... and with 243AI... I hope you like 600-800rnds of barrel life. (tops)
I wholeheartedly agree. When I shot 243ai I was using Winchester brass and 115 dtacs. Some lots of the DTACS shot GREAT, so were ho hum. It was hard to get and keep in tune. I have since started shooting 6 Dasher as well. I have not done much load development. Every load I have tried has been under 1/2 moa and there is almost no vertical at distance. Using Lapua brass and Berger bullets was the easy button, but I have also had decent luck with hornady 105 bthp. Most of the targets we shoot at like diamonds and round targets become wider when there is less vertical stringing. This helps with wind calls that are not perfect.
Also, there is very little true difference in performance between the 2 loads except energy on target. I can see splashes better with the 115 going 3050, but I see trace more often with the 108 going 2830. Also, if you make a wind call that is off by 1mph at 1000 yards with either load on a 2 moa target, both bullets will hit the target. Change the error in wind call to 2 mph and both bullets miss. There is less than a 1 mph difference between the two loads on an average size target at 1000 yards even though the actual hold is roughly .5 mils different in a 10 mph wind.
I agree 1000%. Ultimately consistency matters more than raw performance. There is no laser beam that is hold center and shoot to 1000 in a hurricane. We have to compensate for gravity and wind drift. When the results are consistent you can compensate the same way and get hits. When the cartridge has the demeanor of a red headed stepchild sometimes it is hard to chase down the right dope. I don't really care what I have to dial on the turret or hold in the retical as long as the bullet goes where I want it to. The 6 br variants just seem to be way more consistent performers than the speed demon 6 mm cartridges. When hunting, where energy on target is important, I would tend to lean more toward the bigger cartridge. For everything else, there is no reason not to shoot a 6 br variant.
That shit is a myth. I have tried it. It is a good way to get extra performance and better barrel life. It is better than the typical 6 creed running 4350 hard enough to get those speeds, but I've never met anyone in real life that got the outrageous claims across several barrels.
Most guys getting 3k plus barrel life are running 28-30 in barrels around 3000 fps. Guys getting 3200 fps+ out of 26 inch barrels are getting significantly less life. There are the anomalies, like the barrels that won't die, but those are the exceptions, not the rule. Jacob Bynum talks about a 308 barrel that had around 20k rounds on it and still shot .5 moa even though 4" of rifling was gone. I absolutely believe it happened, but I doubt the results are repeatable over and over. It is the same with the 6 comp match and 6 SLR claims.
