Re: Sierra or Berger

ta - yeah I have hit large lot# to lot# variations too and had to rework loads. I'm surprised that wouldn't be seen with other manufacturers bullets as I can't see how they would change dies that frequently. Yeah I buy a barrels worth once I know it will shoot in that barrel. Mitigates the OMG I can...

Re: Sierra or Berger

Re: NECK CLERANCE - IS IT IMPORTANT?

Hey Bruce - yip .5 moa vertical all of the time is a challenge...you can have a great tune in summer but no so much in cooler months. IMO thats not related to neck thickness or clearance. My point is I have achieved that and better often enough to be on the mound at any given time and expect that ou...

Re: NECK CLERANCE - IS IT IMPORTANT?

IMO you can have brass that has an uneven neck and still be concentric to the bore, you can have even necks and a bullet that isn't concentric to the bore Agreed, but Can the projectile be concentric with unturned brass that is sized in a bushing die? If the neck is uneven and it is sized from the ...

Re: NECK CLERANCE - IS IT IMPORTANT?

Perhaps it went like this..... In the beginning there was brass and it shot well one day a shooter said let there be better precision and so turned necks. there was better precision, then there were split necks so the shooter said give me less clearance between the turned necks and the chamber and t...

Re: If ballistics is a science ....

Define necessary. I've got plenty of 1k targets that show .5moa or less without neck turning. I don't however hold any 1k BR records. Yes consistent neck tension plays a part - the question for turned vs unturned brass - when will it start to show a difference. IME using Lapua brass its somewhere be...

Re: Pussy pads otherwise known as recoil absorbers

Whichever brand you buy make it one inch thick limbsavers are good my back then 17 yr old was shooting .308 185s after moving from a 6br 105s and was unconcerned about the recoil Personally I would go the .260 for them if those are the two choices. very accurate, long lasting and you have to read th...

Re: Problems with CCI 450s

you only need to strike it harder if you don't have much of a dent in the primer. If the primer has a large dent in it hitting it harder won't help.
In a lot of good dent but no bang situations I have looked at, I believe the primer can be seated much much deeper.

Re: 2019 LRWC AND PALMA

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...
