308 150 gr MBW?

Yes, it is caused by the PC at least in part. I don't know if the throat is short or not. It is a factory Savage. The bullets are jam fit into the lands. For reference, jacketed bullets I use all seat at book OAL or longer.

An OAL of 2.890 would probably exceed the max length to fit in the magazine. In my .308Ws, including my M1A w/M14 barrel, I use OALs of 2.645 - 2.687. That keeps the GC inside the neck. The shorter length has the GGC top at the case shoulder/neck junction.

The 30 XCB was designed for a 30-06 length neck but does work very well in .308W length necks.

For my rifles with “standard” .308 chambers, I load them to 2.680”. For the 1-17” twist rifle, which has a different throat, I load them to 2.760”. That length also works in the 1-12” M40ish which uses AICS mags.

I've pushed 145gr PB to 2100 in 1:10 AR BO carbine. Special alloy, coated and MOA @ 100. 2400 fps for AR10 1:10 carbine did MOA @ 200. The bullet you show won't work. I use my versions (kinda copied it for the BO 145gr) of the Accurate 31-165A. My 24" barrel does 2700 but dang that thing is heavy. Haven't tried the XCB or 266 (IIRC that one is kinda a bore rider and could be problematic in S.S.), assume they will work. Quality of your cast bullets will make a big difference so don't expect to much at first.

Well, I have somewhat cooled off on my pursuit of casting rifle bullets. It seems there is way more to casting and shooting rifle bullets than I originally thought. You folks answered my questions, and your recommendations were most helpful. I am putting this on the second or third burner for now as I don't wish to give it a half hearted effort.

I'm overhauling my 700 now. Giving it a new bedded stock. My best measurement has it at a 12 twist so I think it might be my choice to work with cast bullets anyway.

I'll follow the forum and keep mulling this over. Thanks again.

Which version of the 700 do you have? Is it the Varmint with a heavy barrel. If you already stated that, sorry, I missed it.

Yes, I have the 700 SPS. 26" heavy barrel. I checked the twist with a cleaning rod multiple times and determined 1:12.

That should be a great boolit slinger

It is indeed 1-12”. I have one as well. Or, I should say my son does. I gave it to him.

The 30 XCB will work very well in that rifle.
