Thanks for the info CR500. I've got a few Shockwaves somewhere I'll be cramming down my barrel in the near future lol.

The 250 SST fits without resizing or knurling. I tried a 300 sst and it was too tight right before reaching the powder. I don't want to hammer it in. After measuring, the 300 SST is .0005 larger than the 250 SST. The 250 SST can be had at Walmart under the TC shockwave brand part number 8242 and the bonded version is 8245. The IMR 4198, for some reason in this gun, is more accurate and consistent.

I have some Barnes 300gr Expander MZ #45131, that when knurled, fit very well. I haven't shot them yet. They are a long projectile that may be better suited to the conversion due to the increased twist of the 45-70. I am concerned they won't obdurate into the rifling properly, being all copper.


A better bang for your buck is to buy the 250gr FTX's in bulk 50 packs or the 225gr FTX's in 100 packs. The all copper bullets will shoot just fine in your gun. 250gr TEZ's and 225gr XPB's will give a little less recoil then the 300 grainers. I would duplex with SR4759 but that's just my opinion. I like the added security it provides. Good Luck!!

I am currently using #45201 250 FTX but with the scarcity of ammo, I picked up the TC's at Walmart just to be safe. They shoot and load the same. They are 11 dollars for 15 = 33 dollars for 45.

I am on the fence about duplexing due to the complexity of it when reloading in the field under pressure if you know what I mean. My load seats tightly on the powder. I am gonna put my loaded rifle in the freezer for a few days next month and see how it shoots.

The 250 shockwave fit perfectly in my stalker without sizing. I'm gonna try the sst's.
I would love to hear how the 300exp shoots sabotless as this was an incredible bullet for the savage you now own ;\)

I tried a duplex load of 10/50 4759/n120 with the shockwaves sabotless & actually shot better with straight n120.

Dumb question, but I've never shot sabotless... I assume if the bullet loads to hard you would just pull the breech plug and push it back out of the barrel?

I am considering trying sabotless in my Apex in the spring.

Yes, it is best to leave the breach plug out when testing bullet fit. If you can push it all the way thru without beating it thru but with at least 30 pounds of force, you are good. Every bore is different so you will have to experiment. If they don't fit tight enough, just knurl between two files. I am using a wool wad that looks like a half inch diameter by three sixteenths fuzzy disc. It is said to keep out moisture and aide in sealing the charge upon firing.

Take a fired 30-06 and .223 case to Advance Auto and get some valve covers that fit each case neck. Use the .223 case for booster and 30-06 case for main and tape them together. Makes for a quick duplex reload in the field.

If your satisfied with bullet fit and ignition then your good to go with a single.

That's not a bad idea. I currently use a 270 case and a piece of round belt that we use on a conveyor at work to seal the case. We have a smaller belt that would likely squeeze into a 223 case. The 270 case holds 63gr of RL7 for my Savage too. Thanks for the tip. I may try it later in October.
