Re: Litz BCs 330g OTM

Thanks for the help Bryan. I need to shoot the "tall target test" anyways, to check my scope for plumb, after I moved it. I never thought of doing it that way. I've never had a scope that wasn't exactly 1/4MOA, so I've never had to deal with that. I dont think it will be a big deal if thats the case once I get the correction factor. Lets say my clicks are 10% short, would my correction factor in shooter be .9? How ever it works out, it gives me an excuse to burn up some more powder

Good shooting, sounds like you're off to a great start.

Take care,

Scope click error input is over looked alot. The shooting scope test I have found is to easily miss read because of human error I like to clamp the rifle and wind it around an inch target grid at 100 yards

Re: Litz BCs 300g OTM

Think I may have found the problem. I'm using a Forster micrometer seating die. On my second batch of loads it seems the stem is too shallow. It is slightly deforming the tip. It was definitely worse on my second batch. I sent an email to Forester to see if they sell a VLD style stem/plug. If they don't, I'll drill it out. I'm sure this second batch of loads wont shoot real well at distance, but I'll get to find out where I see pressure signs. I loaded 3 each in .5gr increments from 89-91gr of H1000. Once I get the seater stem worked out, I'll shoot the close target test and measure POI change vs MOA adjustments made.

Youngbuck, Most of the time that pressure will show up just after 91 gr in a 338 lm. I have made it to 92.5 . But lots are different so the 1/2 gr stepps are best. Also it sounds like you might be running pretty high neck tension. Do you have a way to back it down? Bushing change?

Jeff

Re: Litz BCs 300g OTM

I would have to agree about the neck tension. My old man actually loaded this last batch. All my reloading stuff is at his house. He knows what he is doing and even asked me last night how the seating went for me during the first batch. He said the neck tension seemed higher than the first run. I'm using a forster FL sizing die. It looks like they only offer oversized expander balls up to .308. I suppose I'll have to bite the bullet and buy some bushing dies. That whole process of bushing dies is new to me, one of the reasons I went with the Forster FL die. Thanks for the info, I have some reading to do. I've only used plain RCBS FL dies for my rifle stuff.
