5mm trajectory



Log in to see fewer ads
i can not find any trajectory tables for the centurian ammo at 2550 fps. i have seen the charts for the original ammo but i would think the newest varminter bullet and its 2550 velocity would be a little flatter.
also, any charts using other than 100 yd. dead on info? i would think the odds are there is an optimal dead on range and 100 yds. isn't it.
thanks, bob noffs

today i found a web site with a calculator that is pretty friendly. i had to use a ''ruger 204'' and the bal cof. for a 32 gr for that caliber but other that that the numbers i am going to give should be very close. i really didn't account for the 2 grain advantage of the heavier bullet.

with a 1.5'' scope heighth..

zero at ...30 yds.
zero at ...130 yds.

max mrt at 85 yds 1 inch

100 yds...1 inch high
150 yds...1/2inch low
200 yds...4 1/2inches low.

beyond that i think i would be better equipped with mt 22/250.

i am zeroed now for 100 yds so 4 clicks up and i am ready to go!

Thats about what I have found when I zero for PD hunting. I don't use the 1 up at 100 but just zero at 100yds and then use the mil dot scope for the adjusted range out to 200yds. It works for me to just do it that way. I have my 17HMR scoped the same way and only drag it along to use for a back up or as a loner for some one. I limit the 17HMR to 150yds because of the drop off in performance beyond that.

5mm mag.

you may not be able to find any charts because listed vel is only 2300 not 2550 or so says the manufacture some say they are getting 2550 some say 2370so i dont know whats what but i would think the factory has checked a few.http://5mmforums.com/forums/index.ph...graph-results/

This was pretty close to the average yesterday out of my CZ 5mm, using a new box of the Centurion Varmint ammunition:



I get 2535 averages out of my 23" Contender Carbine.

Gee, Eric - in looking at your Post #11, above, it's a little hard to tell which rifle you really like. Could you be more specific?

I like the 5mm a lot, but I paid RFC advertising fees to let you all know about it!!

All kidding aside. I love all the rimfires and often have a hard time choosing what's going with me when I go hunting!

What's your take on a side by side comparison shooting pd's with 5mm vs. 17 hmr.
I'll tell you in advance that I've had a Sako quad for about a year and after all the wild claims about 17hmr I was completely unimpressed with it's performance on pd's. The accuracy however is outstanding, I can hit stuff way farther away than I can make clean kills.

The 5mm hands downs will out perform the 17 at any range. With the new Varmit the speed it the same but with the 30gr bullet over the 17gr their is no comparison. The slight recoil of the 5mm lets me see the impact of the bullet and thats half the fun.
