Well I guess I'm a little confused in refererence to these big actions being cut to accept mag feeding, take a Defiance/Curtis/Stiller LM action for instance, their big actions (.750 bolt) can be cut for both. What's the purpose? As you said that most use single feed; I would assume because of COAL limitations. I'm guessing like Steelhead said; so hunters can use them with what I assume is cartridges that don't need to be really long. There's a .375 Cheytac on GB that is built on a Stiller action in a Cadex chassis; it comes with a magazine but none of the ammo that comes with it (I'm assuming it's factory loaded ammo) fits in the magazine so the rifle has to be single fed. This rifle is a good example of my confusion. What would be the purpose of building this particular rifle like this? Below is the ad from GB. I think this is a confusing ad anyway "CheyTac Tac 408 chambered in 375CT" doesn't make any sense to me lol. Anyway, thanks for the info.
I'm assuming that is based on the Cheytac parent case (.64) and that magazine is specific to the Cheytac platform (M200 or 300). Are you getting the optimal COAL you want inside that mag?
I'm going to buy a Stiller Tac Driver action and hold on to it until I have some more funds to get everything else. After everything that I've read, this is the route I'm going to go. What barrel length would give me optimal speeds with the 50 cal powder? Have you tried the 50 cal powder in your Carnie? Do you think any of these barrel manufacturers would spin me a shouldered pre-fit for the Tac-Driver? I'm thinking I'm going to get it chambered in 338 something and stick to the lighter bullets like you have pictured. What would you recommend for chassis or stock? Appreciate it.
Which powder and what round are you wanting to know about? I run H50bmg in the Carnie. It’s still really too fast of a powder for the capacity to bore ration. A tac driver with a Lapua bolt is a pretty nice setup. As for chassis or stocks, that’s a personal preference thing. Also you need to consider your use.
I figure that H50BMG is a pretty good powder to build around considering no one ever ran out of it during this pandemic raid of primers and powders. It's also temperature stable and still fairly priced. What would be THE optimal burning cartridge using the H50BMG powder if you had your pick? Assuming of course the different variations of cartridges built off a Tac Driver sized action. Thanks.
