Re: throat angle

Hello Frank and Peter. I'm with you, I'm a jumper. It's one of the polarising issues; jump or jam. Not much point in a debate, neither side will convince the other. Floaters take care of themselves. But I would like your views on this proposition. If you jump, it is likely that you will not need to...

Re: throat angle

Frank, Peter and Williada - Thank you very much for your data and information I've landed at leade angle not being a significant contributor but an influencer to some extent on precision. Its interesting but most I have spoken to with the new 200s and fast twists that couldn't get them shooting to s...

Re: throat angle

Thanks Frank. Assuming there isn't a CoG issue a lot of it seems to come down to not really understanding why a tangent is friendlier than a secant as a general rule..exceptions agreed and understood. I do work on the basis that a bullet manufacturer has put in due diligence and can actually get the...

Re: throat angle

Thanks Bruce. Yes agreed that a lot of testing is needed and I appreciate that potentially no one has done that. I am after just thoughts at this stage. I have other 200s working very well (in .308) and I am playing with one of the new gen High BC .308 200s. The 1.3 plus all of my other tricks can't...

Re: throat angle

Just out of curiosity can anyone point me to testing of a crooked chambering vs precision and improvement using jam. The theory of jam makes sense I just haven't seen any testing around it. Don't worry not asking for proof just curious if there is something in print I can read. Also - what are the t...

Re: throat angle

I'm not sure about jump not mattering IME it definitely does. Some ogives are more sensitive than others. The single biggest issue is no one can explain why it matters more with some ogives. Personally I would struggle to believe that a specific ogive shape wouldn't shoot in a specific chambering, I...

Re: How to hit the bullseye at 900 yd?

SRP is really common in FTR with heavy bullets as it handles the pressure much better due to the extra metal around the flash hole. If comparing Lapua LRP to SRP Brass I've heard that the SRP brass has slightly more case volume and can need .5 grain more to achieve similar FPS. Precision is just as ...

Re: How to hit the bullseye at 900 yd?

53 at 900 first time up is pretty good going IMO - well done There is a very good book to get - "the wind book for rifle shooters". It will give you a lot of principles to work on. An important one - when to start shooting and when to stop shooting. IMO the most important thing you can do ...

Re: Problems with CCI 450s

From another forum: Thomas Gonzalez : A perfect setup on a loaded round ready to fire would be to have no more that 0.001 gap between the shoulder of the loaded round and the shoulder of the chamber. and at least a firing pin with the minimum protrusion, .050 being the minimum and .060 being the ma...

Re: Problems with CCI 450s

Does any one else have problems with CCl 450 mags. l have a lot of misfires, I'm using Barnard actions which l know they have a short firing pin protrusion. I shoot them exclusively in a 6Br and .308. I never had an issue (I wore the 6br barrel out using them) until i bought a 21 century primer sea...

Re: Alpha munitions brass

Peter. Please define your last sentence ? And has ANYONE ever properly tested case weight variation vs long range accuracy ? If we use Lapua cases we need not bother weighing ? I do and don't weigh them. I'm waiting for that guy Bryan to publish some test results. You should contact Donovan on acur...
