Noslers website lists the same starting and max loads for Accubonds and Ballistic tips.

I've got some old nosler solid bases. None of the reload data I have or that I can find lists load data for these 180gr bullets using Reloader 22 powder in a 300 Weatherby.

Since the Ballistic Tip is supposedly the same bullet as the solid base with the exception of the polymer tip. Would it be reasonable to start working up loads for these solid base bullets based on the ballistic tip start and max load data?

I'm not asking nor suggesting these bullets are completely interchangeable. I just want to know if the load work up range is the same.

Thought someone here would either have the data or experience with this.

I believe data that doesn't list Reloader 22 may still be useful if it has start loads for the solid base bullet with Norma MRP. I have heard several times that Reloader 22 and Norma MRP are extremely close in performance.

i interchange the bullets with the same powder but i try never to reach max loads. they hit a bit different point, but the pressures always seem quite close. it you're going to go to the max, then work up to it. i quite that finding that a grain or 2 under gave me much better and consistent accuracy

Yup. Use the same data. Start low work up slow.

IF your rifle is a "Weatherby made" 300, then I think you will be perfectly safe using BT starting loads.
IF your rifle was put together somewhere other than Weatherby, I would start even lower and work up.

Thanks for the help guys.

It's Mark V with factory barrel and chambering. But thanks for the warning Aliveincc, I know you have a valid point.

One other thought: the Weatherbys are very much over-bore calibers, and require a lot of freebore to keep pressures down to acceptable levels. If your load book gives a cartridge overall length with a specific bullet, stick to that. Otherwise you may have significant pressure problems...

Data isn`t too hard to find

Check the Nosler manuals, #4 - #6 all list the same 76.0-80.0 gr of R22 with their 180 gr Ballistic tip in the 300 Wthby. The #4 book actually calls the bullet a "180gr Solid Base Ballistic Tip".
A Fed 215 primer was used in the books.

I remember buying Ballistic Tips in the past that were packaged exactly as shown in this picture. They are described on the box exactly as your #4 book states. Nosler stopped making the solid base (lead tip) bullets for a while and only offered the ballistic tips (solid base) instead. I've heard they've started making a few regular solid base (lead tip) again.
