Since I have sold my 416 Taylor and trying to sell my 416 barrel I'm upping my pace looking for a 375. Currently my biggest round is a 358 Norma. Due to some medical issues I want to try and stay at or below the 375 recoil level.(I hate muzzle breaks)

After looking at the CZ, Ruger and M70 yesterday and having seen the Whitworths in the past a Whitworth in good condition would be my first choice.

I have a new Whitworth Magnum stock. Cross bolt set up for the barrel lug etc it has a little charater. I can pick up a blued Daly 375 Barreled action for $389. Would this make an acceptable rifle?

Yes if it fits or you could sell the stock And go from there. I have no idea
if the 2 will match up are not. There are regulars on gunsmithing who will know. If you deside to sell let know.

Don't know what your medical problem is (assuming maybe spinal) but it seems like setting a cutoff between a 375 and a 416 is cutting it finer than medical science could estimate. There is more variation from gun to gun than there is between those two calibers. In fact, I have a Taylor, on a relatively light rifle, and I think it hurts less than most 375's. I think this is due to the low powder charge wt. In the recoil formula, the powder charge is a big contributor since its assumed exit velocity is much higher than the bullet, therefore generating a lot of kinetic energy to dissipate.

IMO, recoil damage and/or physical discomfort are heavily influenced by recoil velocity and the acceleration associated with it. The 375 will have a sharper "snap" than any of them. If I had a limiting condition, the 358 Norma is the one I would absolutely stay away from in the list of calibers you mention.

As to the 375 you asked about, you should be able to make it into a nice rifle. I bought a similar surplus stock from Numrich and screwed a 458 barrel into a VZ24 for my brother-in-law. Outside of a misfit at the front and rear corners of the floorplate, it made a really reliable $200 pounder. The Charles Daly should almost be a drop in.

If this is the route you choose, I would do a couple of things. 1) Make the gun heavier than normal to tame the recoil and 2) use a foam filled glass stock. A lot of people don't buy this argument, but I am convinced that the filled stocks soak up a lot of recoil. The Taylor I mentioned has two stocks. One is a wooden stock for show, the other is a B&C Kevlar reinforced glass stock for hunting. They weigh about the same, but the recoil effect is much lighter with the glass stock. I don't think you will see the same effect with a solid molded polymer stock.

Invader, I have a Daly normal magnum action setting in the stock now. The 375 action should fit. The Screw holes are the same distance apart. Might need a little inletting for the longer mag box. Barrel contour might be different.

If I decide the stock is surplus I'll give a shout.

Art, I had a 416 Taylor I had built on a synthetic stock. With 400grs it got my attention. My friend now has it in Alaska and loves it. I was going to rebuild a 416 using a heavier stock. I have had the parts for 2 years. Currently I have a poorly healed sterum and the Dr suggested to go easy on the recoil for a while longer. I thought I would just sell the 416 Taylor parts play with a 375. When I go back to 416 maybe jump to a Rigby.
