1. ### Long range shooting the 45-70.

In my local F Class matches the black powder shooters shoot with us. Mid range only (200, 300 and 600 yards where only black powder shoots at 200). Their x ring is about 2 MOA where ours in F Class is .5 MOA. Most of them are shooting 45-90 at 600 with 500+ grain cast bullets. Those guys can...
2. ### F-Class rifles

What he said. I shoot a fair amount of F Class and use different rifles for different purposes. FTR I use a Savage LRPV in 223 with a 1:7 twist throated to handle 90 grain Bergers. F Open, I started with a Savage Model 12 LRP in 6.5 Creedmoor. Now shooting a accurized Remington 700 with an F...
3. ### How much wind does it take?

True but I was replying to the "all other things being equal but weight" question. As you point out, things are never equal in the real world. A 300 grain 338 bullet has a higher BC (~.8 G1) verses a 140 grain 6.5 (~.6 G1). Driven out of a 338 Lapua at say 2900-3000 fps verses a 6.5 at say...
4. ### How much wind does it take?

I'd recommend "The Wind Book For Rifle Shooters". It articulates the principals fairly clearly. A force acting upon the object in flight does change the trajectory and according to physics the object in motion will continue in that motion unless acted upon by another force. The motion caused by...
5. ### How much wind does it take?

Actually it is basic physics. Assuming all being equal except weight, more force is required to move the heavier object the same distance. Of course all things are never equal but that was the proposition.

I'm using the Giraud Annealer. Yeah, I'll bet that Norma does require a longer (in my case) setting.
7. ### How much wind does it take?

There is more force required to move the heavier object the same distance. In your example though, both 125 and 180 are low weights. I'd go with 140 and 300 (assuming 338 Lapua).
8. ### Load Development Ruger Precision Rifle .243

I just annealed all my 243 brass this last week. The difference between Lapua and Hornady brass are amazing. The Lapua brass does not come up to temp nearly as rapidly and I need to slow the annealier down to get the temps.
9. ### How much wind does it take?

Yes, that will provide the answers. I use Strelok on my phone.
10. ### How much wind does it take?

Need the three variable that will affect the flight. The weight, the time in flight and the speed of the wind.
11. ### How much wind does it take?

The variables for wind drift are force, mass and time. The force of the wind causes deflection. Deflection is the change in angle between the muzzle and the target. At 50 yards the deflection may only be 1/4 of an inch. At a 1000 yards (assuming no further deflection in either direction, as in...
12. ### Load Development Ruger Precision Rifle .243

Thanks, I'll give it a run. I've got 500 180 Hybrids to burn through but yeah. they sure sound good. .755 G1 BC. That's unreal. Might try to get some as the weather warms up and I can do some decent load dev.
13. ### Load Development Ruger Precision Rifle .243

Some are doing it that way. I think consistent neck tension is a key element in low SD numbers which translates to less vertical but everyone seems to have their own special sauce. I think I heard that Bryan Litz won his first F Class national match with new unfired brass. I'm going to be...
14. ### Load Development Ruger Precision Rifle .243

In theory your brass will not last as long and you will need to trim more frequently. The reason being of course that more of the brass will end up becoming worked more fully than neck sizing alone where the bulk of the brass is already fire formed to the chamber. Lot of variables are going to...

For those of you who want to get into neck turning, something just got posted in the reloading section of the classified that will take you one step further down that rabbit hole. :)
