Round holes and good accuracy don't necessarily mean you're getting the most from the bullets, though. As I meantioned in the other thread, if it's yawing more out of the muzzle it can hurt its BC.
Also something some may forget about--punching a hole in paper isn't all you ask a hunting rifle to do. One of the reasons I'm leaning toward a faster twist 300 is for on-game performance. Less chance of tumbling on impact and straighter penetration with the long heavy bullets (especially bonded). If Richard gets me the 240's before I get a new barrel, I'll test them and use them if they do OK, but I'm slowly convincing myself they'll do better with a faster twist.
O.7 inch bearing surface will be good. It is too late for this hunting season to get a new load ready because I am so far down the road with the 160 Accubonds, but there is always next year.
The way I measure bearing surface is to hold two of them against each other and to place the caliper jaws where ever I begin to see daylight - real scientific. But when your throat is measured in miles instead of hundredths of an inch it doesn't much matter
If Richard doesn't have any let me know and I can probably spare some.
I'm limited by case capacity much more than you, but that will be remedied shortly I hope. I will try compressing a little more if the test loads work o.k. and see what happens. I think I could get 2900 but that's probably about the most with my rig.
Waiting for a new gun is worse than cabin fever.......
Even your 1-9 will be marginal but they'll be fun to shoot and test. Go for it!!! [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img]
I'm emailing him now to add to an earlier order for some 270 cal 169.5's for my first APS rig and more 7mm 169.5's that have been working great in my Rum.
Cabin fever it's more like being tied up in a straight jacket. I've been bouncing off the walls counting the days and weeks as my parts are still on order.
I get excited hearing Bill Bailey and Lerch will be getting theirs here soon to give us some range reports on their turf. I expect that the Chucks in their area will be running for cover when the UPS truck arrives with the package from APS!
Guns and ammo, what more do we need?
IF their were any chucks around here I swear to you they would be in trouble, but all we have is prairie dogs and I think they are a little smaller. we went pdog hunting last night and kept thinking about my UPS delivering my Allen Mag in a couple of weeks so I had to ask the prairie dogs "What can Brown do for You".
