300 Whisper Owners... Please sound off!

[Quarterbore]

We are having a huge number of people that click here and move on without posting. Please take a second and post about your 300 Whisper (or clone), what you use it for, and your experiences with the round...

From the statistics I have running it looks like we have had about 1000 people come to this forum and we only have two posts...

Last year about this time I put to gether a Model 1 sales kit on an Eagle lower. 16" CAR, A3 upper, Standard FSB, fluted and knurled FF tube, trapdoor A1 buttstock, Ergo grip, ARMS #38 SEX, Simmons Whitetail 4x EER shotgun scope, extractor D-ring, and Armforte adjustable gas tube. Rolling my own with Redding dies, H110 and Winchester .223 brass...

My intent was to build my ideal 0-200 yd. whitetail rifle. So far I've been very happy with everything but the ammo... I form from .223 brass, and originally bought a bunch of LC once fired. That stuff does not form well at all. I've since switch to commercial Winchester brass and am pleased with the results. Groups have consistently printed MOA + or - a gnat's ass. I really need to upgrade to some real optics, but for the money the little Simmons works well for deer season and makes for good go/no go field expedient rangefinder.

Cheers!

I struggled greatly with handloads using H110, but have seen much improvement since switching to Alliant 2400 and CCI small rifle MAGNUM primers. Most loads have been with a Sierra 240, but plan on experimenting with the 220 some more.
At least you can get the the 220 by the 100.
240's are only available by the 500. Think I payed $155 from www.okweber.com.
The Winchester action doesn't seem to like to eject spend casings reliably.
They jump off the the extractor and sit in the breech. When they do eject they don't go very far. Haven't messed too much looking for a cure as right now accuracy is my main intrest.

I am going to try to have a shorter firsh handguard than the gas block, hard to do on a 6" pistol lengh possition. Going to put a bilock on 5/8x24 threads, 1/8 twist,

hope it works with my RLL!!! in fact I mean to make it work but wont be too disapointed if it takes a bit of fiddiling

bought some of the flat base 180gr remington core-lokts, works out to about 8cents , hope to have a loaded ammo at about 10c, Mr. Davis hooked me up on the brass

I will post some pictures and such once I get the rest of the parts

Can't wait to go to the range to test.
That's my story.

You really need a chrono if you plan to shoot subsonic loads accurately.
If you are just shooting supersonic for groups you don't really need one unless you want to run ballistic tables.

I like the idea behind this forum and I hope it grows and becomes popular, but one of the reasons that it attracts people who don't post (I think) is because there may be a lot of people out there hunting for good reloading data on the cartridge, but there is not a whole lot of it here.
About guns: I have a Contender (bought it in 17 HMR caliber) with a 300 Whisper barrel, but haven't shot it yet because I've only just now started trying to load the caliber. The rifle has a very good trigger, and once I finally get some loads worked up for it, I'll post them here. BTW the Whisper barrel is a stainless TC barrel in 1:10 twist, so I am pretty much restricted to loads in the below-200 grain bullet area. This is OK because I really do not want to pay the outrageous price of the 240 grain Sierra bullets that are used for subsonic loads. I do have some Lapua Scenar 185 grain bullets that I am going to try working up loads for. I have seen some loads using this bullet on other websites so i will start there. Have a good day.

I get the first real/non quoted post on the new thread!!!

I just received my Model1sales 300-221 A.K.A. whisper 16" CAR, A2 flashhider, Free Float Handguards, A3 Flat-top upper, jard single stage 1.5# trigger.

From the old forum :

I haven't really had a lot of time to play with it yet however I did get a chance to put 5 rounds through it at the local indoor range.

I was shooting 220 seirra's in 221 fireball cases with 9.0 gr h110. The spent cases ejected properly but it would not strip the next round from the magazine. I was only loading 2 at a time in a 20rd DMPS plastic mag but it always looked like the second round was being over-ridden by the carrier. Manualy cycling the charging handle loaded the round properly. I worked the charging handle a few times and it feels like the bolt-carrier is riding rather roughly in the upper. I'll sit in front of the TV and cycle the gun a few times to try to work it in a bit. I have a Model1Sales 6mm PPC varmint gun that used to fail to load untill I had let the carrier wear in and now it cycles flawlessly. I'm loading another 50 rounds with 9.1gr of h110 to see if that helps as well.

So far my impression of the rifle is very favorable. The recoil is non-existand. It sounds and feels like I'm shooting a 22lr until you see the size of the holes in the paper!
