Thread: Shorter barrel = less velocity?

thats a soft load, even for me.

25 06 Tim

Nonono! 2506, not .257 Wby! You are right about soft!

One could only assume given the name but no mention of case

Yup quickload was within 10 fps (of the average vel) for the last 2 loads I chronied. Quite surprising

What he said, i be amazed if it was getting more than 2700fps. Expect it somewhere in the 2600-2700 range. Normally tested in 24 inch barrels, will struggle to be dead on what the box states minus 25-38fps per inch chopped depending on the rifle .(150-230fps lost)

Hey Timmay,

Cheers for that, a little behind what I'm getting, but not far away, a really handy tool, how do you get hold of this Quick Load carry on?

your pushing shit up hill with a twig to be honest mate
factory ammo speeds on the box can be quite a way off even with the full lenth barrel yours is 18inches which will be less but by how much is a geuss same as the 1st geuss of that the ammo would do in your barrel
if you punch a random geuss which at the end of the day is what it is into a ballistic calculator it will almost certainly be wrong and you'll end up just confusing your self
the only way is to crony your rifle with that load... even if you foud someone with exactly the same set up as you the speeds would be different

if you have the room you could zero your rifle at desired distance
go back 50m fire a shot go back another 50 fire again go back 50 fire again all the way back to the longest you want to shoot and make a note how far low of the 1st shot each shot at each distance
its the only way of working out your ballistics without all the gear

you may say its only to give me an idea but its better to have no idea than the wrong idea

Yeah ive zeroed my rifle at 100m and have gone out in 50m steps to 500m. Would just like to get an idea of how much fps it was putting out

to get an idea of ftlb energy (killing power) I presume
id put in 2700fps that will be a little lower than what your truly getting however any more is a bonus
they say you need 1000ftlb to safely kill a deer at a given distance
right using Nikons spot-on softwhere shooting 150gn fusion I have adjusted muzzle vol to 2700 from the listed 2820 nothing else altered
just speed you have 983ftlb at 500m which should be enough with good shot placement

That's the absolute verification! All the other methods are merely confirmed by real world data. Especially if your hitting smack on at all ranges in zero wind.

Interested to know what your 200, 300m drop is
