My New 300 Whisper

[Gelandangan]

Problem solved!!!

I crimped the end of my cartridge so that the tip of the brass is slightly bevelled inwards.


Right!! now, all I have to do is to load it with something consistent and accurate for my barrel. Coz yesterday, on the range I got velocity that varies in the HUNDREDs of FPS.
YIKES!!!

Hello Gelan,
I also got fluctuating velocities when I started loading the whisper, I also use 2205, I changed the seating depth and averaged the loads to find the best one. I was using 11.1gn of 2205 for 220gn hornady interlocks which averaged between 1010fps to 1080fps, annoying but gave me the best subsonic loads anyway. They are brilliant on goats if you keep to neck shots. Shane

I read on http://www.gmdr.com/lever/lowveldata.htm that for subsonic loads it is better to use pistol powder for consistency in velocity. Quite a good read that site.

Due to the fact that we could not get legal silencer cans here in Oz. I think I will give up (for the moment) to get the subsonic load, and to concentrate at the supersonics loads.
I will try 110gn hollow points on about 15 or 16gn of 2205 to see how it works. I also have W296 which is similar to 2205 is VOD but have different bulk.

Gelan, I use 17.6gn 2205 with 125 ballistic tips which gives me about 2200fps which is great for just about anything here in oz. I use it on goats, pigs and roos and it is devastating. I built my own whisper using a weatherby action and brought a barrel from MAB and machined it myself. 20" barrel with a sightron 3-12x42 mil dot recticle scope. Cross hairs centred on 125gn supersonic and using 2 nd mil dot down for subsonic 220gn, both seroed at 100m. Excellent all round rifle. Shane

Hey Gelan, what part of oz you from Shane

[Gelandangan]

Hi Shane, Im from SYdney. You?

Right now, Im loading 16gn of 2205 on some 130 hornady speer point (thats what I got till I visit my local shop next year.. work busy)

Hope I could get to about 2000fps. hta would be just great.

Hi Gelan, live just out from Raymond Terrace. Those 125 I have been loading with 17.6gn are still not too hot so you should be able to get your pressures ok. Mine showed no signs of primer damage or excess pressure at all but were hot enough for me. Shane
