300 Confederate Sharpshooter (300CSS)

[Humpy70]

Holds about 5 more grains of powder, Tapered round so it feeds fine from 30.06 mag well

308 on left

Explain everything about this round please

During the developmental phase of the M14 Rifle the first caliber it was designed for was the 300 Savage cartridge. The ammo engineers felt there wasn't enough support of the bullet in the neck and came up with 7.62 NATO which held more propellant than the 300 Savage. A gunsmith known as Speedy Gonzales designed a shortened 300 Savage and stopping the Savage chamber reamer before it cut the Savage length and it was a very good bench rest round. I forget what he called it.

I called him and we talked and I told him I was thinking about running a Savage reamer in deeper to 7.62 case length, making cases by running 308 into Savage FL die which when removed left a 308 with a shorter neck and more case taper going to the shoulder. It also held more propellant and really shoots well. Friends had a couple made and they like theirs. A lot of 30.06 actions won't feed 308 well.

Another plus if some asshole steals it he is not going to shoot it as no other round will fit in except a 300 Savage and when fired you will have a case with no case neck haha.

I had planned on shooting it in HP competition but the wreck in 2013 shot that down as it stopped my competition. I guess this rifle only has about 100 rounds on it and is loaded with 300 Savage dies.

I can’t help but feel that a cartridge with a name like that will never sell. .30 Sherman? .300 Lincoln? May have a chance.

The most famous conversion for the 303 is the 300 Epps by a guy in Canada.

I did not do that one for several reasons, money and money.

First off you have to buy the reamer which is pricey and then you have to buy the dies which are very pricey.

So I looked at the SAAMI drawings and cases with the same length that has a middle area of the case the same size or smaller diameter so I could use the factory dies (much cheaper that Epps) to form and make the cases and also load it.

So the 7MM Sabre is a 303 back end and a 7 Mauser front end and uses factory dies.

Same for the 6.5.

I also took a 303 reamer I had and had it reduced to .454 diameter (I think it was) at the bottom, then I had the throat shortened to 30.06 length. The factory 303 chamber has the bullet traveling 3/8" end or more before it starts to engrave. Thus I can take factory 303 and shoot the cases many more times as the base only expands about .002" on firing where a factory chamber it will expand maybe .008".

Did you all know Ruger made the No 3 single shot rifle in 303 British for sale in Canada?

Has anyone read he book written by Lincoln's Law Partner where he tells Lincoln's true feelings about this and that?

Hadn't heard of the .303 Ruger, but have hears of the Savage Model 99D Musket in .303 Savage Canada ordered for private purchase home guard use.

Read excerpts from some of Lincoln's associates that are not used in public schools.

Only reason I know about the 303 Rugers was Steve VogeL (Bill's son in law) was a good friend and he told me about them. A few years ago I was reading a forum and a guy in Canada said he had one.

If you can get a set of "The War of the Rebellion" printed by US gov't that lists piles of actual documents from the war. I think there were like 20 volumes in the set and has message traffic to/from various commanders. It is a real eye opener. The full set used to sell for like $200.00 20 years ago.

Only one I have now is a 7MM Sabre built on a No 4 action. Haven't shot it but a few rounds. Sold a couple of them to a friend and he sold them to a mutual friend and he hasn't got around to shooting them yet.

I have a couple P14 actions and I had thought about having a 306 Sabre on one.

I can find nothing else about this round (and I have a Savage .300 levergun which I love).
