Hello, been lurking here a while. I am active duty military, was a Scout / Sniper platoon leader in OIF 2 years ago, and graduate of Storm Mountain Sniper 1 and the GPS defense Warfighter Sniper course. I've been shooting my whole life, not an expert, but I know a couple things.
I'm having a rifle built on a Stevens 200 SA. Right now I have a Savage pre fit barrel on order from Pac Nor (Remington Sendero contour, fluted, 26" finished length, chambered in .243 Winchester) I want to shoot 115 grain DTAC bullets, so I've specified a 1:7.5 twist, unless someone can convince me a 1:7 would be better.
Here are my questions
1. Do I need a special throat for the DTAC bullet? COAL will be limited by AI magazine length. If I go with a standard throat, can my gunsmith modify it for the DTAC?
2. Pac Nor told me I need to send them a dummy round if I want a special throat...only problem is I am overseas and my reloading stuff is in the US..so what should I do about that? I don't have a load worked up yet for the DTAC, as the last .243 I had I swapped barrels on years ago. All I know right now is that whatever load I settle on, it will have to feed from the AI mags that will go with CDI bottom metal.
The rest of the build will be a Manners T5A stock, Timney Trigger & Badger Rail.
Does anyone have any experience shooting lighter bullets in a 1:7 or similar twist in .243..such as the 87 grain V Max? Everything I read says lighter bullets shouldn't be a problem, but I'd like to hear some real world experiences.
If this stuff has already been covered, I couldn't find it. Thanks in advance.
