Hi guys. I was at epps today buying some reloading stuff and ended up with some Berger 190 vld hunting bullets. They didn't have the Berger reloading book, so I was wondering of if anybody had the data for it. I'm using reloaded 22 and Winchester mag primers with Winchester brass FL sized. Any help would be appreciated. The best I could find was re loaders best showing 73.5 gr of rl22 over a 190 Vld with rem 9/12 M primers gave 2820 fps. Would this be a good starting load???

Thanks!!
 
the berger manual shows 68-74 grains of R22 with velocity from 2733 to 2970 in a 26" barrel.... velocity will increase / decrease by approx 30fps per inch in barrel length

i cant offer advice on loads, as well i dont load for the 300wm
 
You could probably work up to 77gr but work up slowly past 75.

Quickload shows velocity of 3074 with 77grains and just under max pressure....YMMV of course.

Thanks cyanide. I started at 68 and did 5 rounds each in .5 gr. increments. I'm thinking it's maybe a little overkill but I'm hoping to end up around 2900-2950 fps. My OAL chamber length is 2.809 and my bullets are seated at 2.770 until I find a decent powder charge. This is my first go at reloading, I've been reading for almost a year but I'm still fairly apprehensive.

Should be able to go up to about 78gr then with that length.

74.5 should put you around that 2940-2950 mark.

With my 300WM I use 1gr increments up to top book load and then .5gr after that to find max for my gun.

Load for the bullet weight. Who made it doesn't matter.

It is unbelievable how much garbage you provide to people. The manufacturer and the bullet type make a HUGE difference. For example, if you had a max load for a 180gn sierra game king and loaded the same 180gn weight bullet, say a NOSLER E-TIP, the pressures would be signifigantly larger. the bearing surfaces that contact the lands of your rifle vary with each manufacturer, some have more and some less which will change the pressure.

I believe the Barnes TTSX, the Hornady GMX, and Nosler E-TIP are the only fully copper constructed bullet this applies to, but do your homework first before batch loading a bunch of random bullets expecting the same bang per powder charge.
 
Mods, can you delete Sunrays post in this thread? Although I'm new at reloading I feel like this is bad info and I don't want someone to read his comment as gospel.
