Can you guys please tell me H2O capacity of your fired cases( Preferably Winchester brand) and OAL with 105s, Please? I'm considering SLR and I wanna do some homework and run some quickload numbers.

Your help is appreciated, Thanks

 

[Rtheurer]

Just went out and measured several.

Current lot of Thick necked Winchester brass.
1. 54.74 H2O

2. Lapua Circa 2003ish 52.62gr H2O

3. Lapua 308 Small Primer necked down and fire formed. 52.40gr H2O ( only fireformed once)

4. Older lot of Wincester Brass with .014 Neck thickness. 54.10gr H2O

I dont know if I got a odd lot# of Winchester brass a year ago or what, but the necks needed to be turned to get .014 thickness like they are normally.

I had a piece of Federal and Remington but have misplaced them, just for a reference. The Federal if my failing memory is correct was the largest of internal capacity with Winchester being a close second.

OAL will depend on your application and reamer freebore. The specs on my 107 bullets are in the first post. My reamer makes it so that they are set at that length to make them functional in a DBM. There are some other reamers out there that will give you 90, 100 or 120 freebore, or you can get one made to your specs.

Thanks guys and sorry I should have thought about OAL :, it'll be magazine length coz I want it mag fed.

XTR,

I have a little experience with the SLR. I've been lurking on the SLR threads here for a while. My good friend RTheurer was probably one of the first people to actually have one. My reamer has a long throat and I use it for 1k prone shooting. I found very good loads with a lot of the powders mentioned here, but I settled on a stout load of N160 pushing mollied 105 hybrids at 3,250 fps. It's kinda tough on primer pockets, but it is amazing how well it shoots there. I have 1,100 rounds on it, and will be taking it to Perry in 3 weeks. Most of those rounds have been shot at Oak Ridge from the 1k line. It is a great cartridge design where many bullet/powder combinations will work.

Thanks Matt,
care to share a starting load using N160? I'll have mine chambered once my 'smith get the reamer back from PTG.
Thanks.

 

[MattKubic]

Start at 44 grains and work up. I found a lower node, but I ended up at 45.2 grains at 3,250. I shoot it only at 1k because it is hard on primer pockets in Winchester brass.

 

[XTR]

Thanks Matt. I've been wondering what would be a good stating point with N160. It's always good to have another backup powder these days.

I will probably look for the lower node. I don't need to beat the brass up if I can get in the neighborhood of 3000 I'm good.

 

[MattKubic]

You will be over 3000fps with the 44gr. of N160. If you stay at 3,150fps or less, the brass will last and you should have no pressure issues. I do shoot moly though. If you keep them around 3,050, bare hybrids will shoot great.

 

[XTR]

3000+ would be nice but I'm not obsessed with getting it there from a 25" tube. If it shoots tight with good velocity I'll be happy.

 

[jamie0700]

What is Matt's barrel length?? Im at 24" on my slr.

Jamie

Matt is a sling shooter, his barrel is at least 30"

 

[jamie0700]

10/4 Thanks. Mine is for hunting and playing. 24" sporter #5 contour. I walk and carry quite a bit.

 

[MattKubic]

Jamie,

Yes, my barrel is about 30". I have another one I am about to chamber up that will finish in the 24"-26" range for some PRS type shooting next year. In a practical world, around 3000 fps with 105 Hybrids is plenty good. I will be testing it this fall.

Matt

 

[jamie0700]

Very good Matt.

I have a few lbs. of N160, and glad to see some load info to get an idea of range for load development. Do you have any experience using VV powder in 6.5 Creedmoor? I also have N150 on hand and wanting an alternative to H4350. Im in my busy season plus its been super hot, and havent had the time for much shooting. Thanks for all the info.

 

[Judd]

Mine is 22" and I'm running hybrids @ 3020 with 4831sc and just a brake...I don't know what it runs suppressed.

 

[Ksmirk]

Bad thing about all the information it makes you rethink you initial plan lol I'd really like to keep a 105-107 around the 3000-3050 range so do I go easy and do a 26" tube or heat things up and go 24" tube grrr lots of good info here fella's! Later,

Kirk

 

[Raptor]

Go 26"s its not a bad length even for tactical shooting and then you will have room to set it back. My SLR started life as a 6XC and at 1800 I rechambered it to a SLR then put another 1000rds through it and had 2"s cut off and rechambered it back to the SLR and now have over 3600rds down the this tube. It still shoots tight to 600 but have noticed it opening up at 800 so its time to pull it. Been a great barrel and owes me nothing. You have to love the SLR and H1000!!!
