Re: 400-425 grain .375 ULD Interest?

I have had a bit of experience with lead core bullets in 416 Barrett.

I found that you cannot push them as hard as solid turned bullets.

I can get 3200 + with turned bullets, 3000 reliably tops out jacketed ones in my rifle.

I was experiencing the same sort of trouble that Berger encountered with the Gen 1 at around the same time.

So I think the weight, length & jacket thickness will be critical to obtain a good launch speed.

Also the twist required to spin up the higher BC bullets will be very hard on the jackets especially if launched hard by the bigger chamberings.

I'm in the process of building a couple of 375s big & small so a bullet that does fly will interest me

As long as its a conventional lead core jacketed bullet , line a SMK in shape with a weight in the range you state , plus has a reasonable BC , you may find , quite a few people waiting for some one to make this bullet , and have some components already , ie a action , brass , stock etc , just waiting for a long range 375 cal bullet to be available.
And when a bullet is made , then they can order the right twist for IT , and start the build .

I have 408CT brass , and have not done anything else for a coulpe of yrs , due to a bullet not being available , just waiting for the 375CT/VM to mature enough to make it a viable system .

Still waiting ,

Later Chris

I have been waiting about 4 years for a bullet like that for my 375 rum improved. 1-10" twist barrel.

This is just a test post to judge interest but the idea is to produce a jacketed lead core in the 400-425 range. Required twist is no matter as I have someone to cover that for me in the barrel business.
