Static concerns Sorry for coming back on this one but as I do not typically see these practices being used at the matches I have been attending, I was wondering if your concerns were based on the powders sensitivity to ignition, repeatability or others. Ken

Al I’d appreciate hearing the how and why for these two procedures. Thanks Ken

Muzzle Kinetic Energy Keith It’s the etc. part I’m curious about. Ken

Analitical model Yes, understood. You have taken on a project; from what I have read there are not to many first order equations. All the best. Ken

Tim I’d like to read more on this. Vaughn says that chamber pressure is not very sensitive to seating depth. ( 1000psi per 30 mil. of free run) Ken

Keith If there is only minimal change of Total pressure from Atmospheric pressure does that not tell us it is Temperature and powder geometry that are the most significant factors in determining peak pressure. Ken

Right; so if I’m following this right, rebar’s physical properties change with relatively small changes in ambient temperatures and Nitrocellulose is not affected by humidity. Something doesn’t sound right there but who knows. A different perspective might be one along the lines of: “There...

I read a thread on another forum (Long Range) about measuring case inside volume capacity and its effects on internal pressures and velocity. I’ve always understood the importance of finding the optimal Load Density/ Burn Rate combination but had never even considered inside case capacity...

Mother Nature wouldn’t have it. Hey Russell All day Saturday I was trying to get motivated but pretty much ruled it out late last night. The only work I got done today was running the snow blower. Hope to see you next week. Ken

Muzzle Blast after-effect Devil’s Advocate After shooting the 30BR I am more curious as to the tune characteristics and mechanical issues over felt recoil with the 6. Looking forward to next year and more testing and observations. Ken

Ben Will you please let us know how you make out; I have never tried it that way. Thanks Ken

Franklin W Mann Bob While reading Test 35 these quotes stuck out and made me think of your tests. “We had not discovered for what we were searching and had no idea of the form of the things after which we were looking.” “Our desire was to keep our minds constantly alert by surprising...

Cool-Aid Question Hi Pete, trust you are soaking in that hot southern ambient air. I am curious as to the correlations you mention: on ambient barrel air and air density. Could you explain? Thanks. Ken

Recording Data Bob Glad to see you are always so dedicated. At our small range from one end to the other there is big difference in temperature because of the wood stove at one end. Another concern is temperature differences through window and how that affects scope and barrel temperatures...

Dunham's Bay Crew Looking forward to it. Ken

Thank you Gentlemen Interesting scope with quality optics; I’ll have to keep watching. It is a 2in with all the parts, no dents but, a few scratches. It’s just something I can’t get used to. Cheers Ken

Thinking of taking this off the Win 52 and installing something more modern. Any idea of value. Fixed power, external adjustments, rings with spring and real long. Thanks Ken

Weather Sensitivity Although primarily an Arrhenius equation, moisture can offset or inversely affect powder burn rates through mechanical and dimensional changes. Ken

For every action there is a reaction. Absolute humidity changes as air pressure changes and varies with temperature. Ken
