230 Bergers

[darrindlh]

Hello,
I am going to start load development for my 300 Weatherby. I want to try to develop a loaf with the 230 grn berger. I have a factory vangaurd 24 inch barrel 1-10 twist. My powders I would like to try are H4831sc, H1000, and N570. I am going to shoot this as a single shot with a starting COAL of 3.700. Are these a good choice of powders to start with?

I think your powder choices are fine. I see no reason to make your rifle a single shot. Both versions of the 230 gr Berger are hybrids and do well with pretty much any seating depth. I would seat them to fit and feed from the magazine. Some might say you would lose some powder capacity/velocity seating deeper. In my experience the difference is small and not worth the concern.

Start with the H1000. N570 can be very accurate, fast, and will eat your throat pretty fast. The velocity gain is nice, but needing to adjust your load after you find it, is not super fun and doesn't always work out as the first one.

I would use H-1000, it burn cooler then the V570. the 570 use nitroglycerin and barrel will get pretty hot after 2 shots.

H-1000.

H1000 for consistency, N570 for max speed and minimal throat life. H4831SC will be to a poor choice for that combination.

Yep. What these guys have all said. I shoot 230s in my weatherby. Prefer Retumbo but it's been a bit of a unicorn to obtain.
