For your review, I look forward to your feedback. I figure this stuff out regular by doing it and use The forum as a baseline. This time I am going to ask you people to shoot holes in in my ideas In Hopes of learning faster and having a bit more fun with my trials, and maybe saving some time. Screwing up my handguns are a quick fix, leading up my rifles takes a lot more time and effort.
The mold is an unused lachmiller 311-169-pt. Recent events have put my inventory for all handguns at staggering levels, all my rifles are well stocked except my 308. So I’m bored and ready for a new challenge. I have near 30 lbs of mix checking on my hardness tester between 18-20. Who knows how much 12-14 I have.
The forums say this bullet works well to about 1600fps, so now the questions. Temper your responses with this info, I cast thousands, I lube/size in a 450, i hi tek coat, I push through size, I hand press, single stage, and run 550. I load 9 calibers. I chrono when it means something.
1. I shoot my m1 carbine lubed and checked at 2000 FPS with no concerns, I shoot my 327 fed with 12-14 hardness without checks hi tek with no concerns. So why should I check these 169’s? I think I can hi tek this gc bullet and run it up to anything under 1800 FPS while I find the castings sweet spot for me. I don’t even see why I need to run my hard lead for this, 14 hardness should be just fine 1600 and below.
2. I’ve never checked boolits in a Lee push through, even if I don’t need them I will want to try some hi tek checked once the sweet spot is found to see if anything changes. Anything unique that makes a check better on a push through I should know? I’m pretty happy with the hi tek, I can lube size if that ends up the best option but I don’t see why it would.
3. I primarily want to put together a round for my 308 long ranger for fun 200 yds and under, my normal game king bullets are getting pretty expensive. I also have two pretty neat 30-06 bolt guns. I expect that once I’ve tailored the 308 case to my goal I can the chrono the same load in the 30-06 case and increase the powder to reach the same FPS, I suspect the round would be slower as the larger case should have a lower pressure based on case volume.
4. My ballistic tables show that a guesstimate of a g1 0.276 on the cast and an advertised g1 of 0.404 on my game kings on a 100 yd zero should mean no necessary changes to my sights keeping me on 6 inch steels out to 150 and a high hold out to 200 before she drops through the sound barrier. If this sounds true enough for trials this would be a blast lever round to play with and really drop my cost per round on all these rifles. I am really wanting to make this work as I can change to my game kings and jump right back to the 4-500 yard steels with no changes.
