Mixing headstamps doesn't seem to make a lot of difference at relatively short distance, but move back a little and you notice it. I've gotten pretty meticulous about my brass these days - use only the same headstamp and keep them sorted by how many times loaded/fired.
After wrapping up work, basketball game, and a completely ridiculous HOA meeting, I went to my laptop and plugged in some number into GRT from accurate loads I've developed using a standard ladder test and follow up groupings. I ran the OBT calculations to see if the predicted nodes matched...
I've been messing around a lot with GRT lately, mostly running load simulations, but there's a feature set up to calculate Optimal Barrel Time (sounds like QuickLoads has this feature too). I'd heard of OBT before, but never gave it much thought, so that lead me to do a little googling and...
Yeah, I saw those too. I like ABs and would certainly use those, but 50 Accubonds are not worth that. There's other options out there, kind of like the OP indicated.
So did I, but it sure does seem like partitions and especially the standard Accubonds have been remarkably sparse for too long. I can sometimes come across ABLR's but Im fairly ambivalent about them. I don't think they are as good a bullet as the standard.
I've been in something of a build-your-own phase the past few years, but I've owned a couple of Tikkas and definitely recommend them. Excellent factory guns. I still have and use my T3X in .308 and I've shot about everything in the Rockies with it at one time or another. I doubt anything...
I believe Scenars are designed to be a target bullet. All I'm going to say is there are a lot hunting bullet designs I wouldn't shoot at a game animal.
I generally keep things to myself, but I'm going to go ahead and say that I find it a little irritated how practically every discussion about bullets and their performance winds up with dismissive comments about "shot placement is everything", etc. Nobody denies that shot placement is the most...
I don't do it every time, but I've definitely tightened up some load combos that way. And besides, the way I look at it, I just like to tinker, test things, and shoot rifles. And I don't consider any time squeezing a trigger to be wasted.
