.300 Win Mag velocity concerns

[J-cat]

Interesting to know on the primers, I hadn't heard that standard LR primers can Ben used with H1000 in .300 WM so I'll have to try in the future. I'm not even close to this point with my rifle but am taking notes.

What is on post 5 that we are supposed to see?
And if you don't think primers affect extreme spread you have never used a chronograph ever.

Please don’t insinuate I don’t use a chronograph. I shoot 99% of my shots through a chronograph, you land chaser.

[longrange1]

what type of shooting do you do and what type of chrony do you have that you shoot 99% of your loads through a chronograph?

and whats a land chaser?

How many shots in a string are you running when you check for ES? The numbers I posted were for a 26 shot string. Also could cleaning every 3rd shot have an affect on ES?

Also as far as primers go I had planned on running 215Ms as that seemed to be the general consensus for a go-to primer with the 215 hybrids but couldn't find any at the time. I found nothing negative about using 210Ms and had 5000 of those on hand so went with those.

Primers are a tuning tool used when you reach a node and your extreme spread isn't what it should be.
On my cell phone there was no page 5 only a post 5 and that doesn't matter anyway.
If the load has a small extreme spread and the accuracy your after it's a good primer.
If the extreme spread is high and the accuracy isn't up to expectations primers at $4 a hundred or the cheapest tuning tool you have available.
When chronographing for extreme spread you pace your shots incrementally with regards to time and a five shot string is good enough.
If you clean your barrel your velocity will drop 35-125 FPS for one to two shots so don't clean or if you need to clean shoot 3 shots before you resume chronographing.

Like I said no page 5 and that entire thread was useless drivel you water catcher.

Thanks I was just cleaning every 3 for barrel break in. accuracy was getting pretty good near the end of my barrel brake in session. started out in the .75"-1" inch range and after 50 rounds was in the .3"-.5" range.

Dang, for a minute I thought LynnJr was referring to my post. Looks like it was J-cat's answer that had him reply. I was simply curious to the primer question. That, I believe has been settled. I think.

It useless to a person who lacks in reading comprehension.

and whats a land chaser?

A person who either breech seats or constantly is adjusting seating length to keep the bullets into the lands the same amount.
