I have some Berger 60 gr Varmint bullets "match grade". They are hollow points.

I have Winchester 748 powder.

I cannot find any reload data that corresponds directly to this combination. I have load data for a 62gr jacketed bullet (came with my Lee reloading dies). starting load=25.1gr, max load=25.5gr.

Question: does 2 grains of bullet weight make that big of a difference? Would you consider this a safe load? Any other suggestions?

Thanks.

Two grains of bullet weight doesn't make a significant difference in the load. You can use load data for any jacketed bullet of similar weight with the Bergers. Of course, you have to evaluate what is a safe load in your own rifle.

If you look at reloading manuals, you will find that frequently the same loads are listed for a selection of bullets that may be 2 or 3 grains apart in weight.

Use the Hodgdon listings in their website.
I use BLC2 with 60-65gr bullet weights. Excellent accuracy and top velocities.

I use 26.0gr with the 60's and 63's, and 25.5gr with the 65gr Sierra BTSP.
Also, 26.9-27.2gr with the 55gr. (difference is in whether I'm weighing or loading them on my progressive machine)

BLC2 and Win748 are the same powder, just different packaging, and ususal lot-to-lot# variations.

If you call Berger, they will gladly share info. They emailed me a spreadsheet actually. Also, if you want to actually talk to one of their techs, I believe that you can, but I might be mistaken.

From my experience 2gr of bullet weight can ammout to a bit of difference, when bullet construction differs. For example a 62 gr flat base round nose bullet will have significantly more bearing surface area than a 60 gr v-max boat tail sharp spitzer with a different ogive creating more drag against the barrel metal and causing preasures to go up. Jacket material and thickness also play a part. At lower charge weights not much of a difference, but at the top end could be dangerous. Similar bullets offer a good place to start, but tryu to go one step futher and look for similar bullet types and as always work up your loads.

You were absolutlely right! Walt Berger, himself, sent me an email with load data for at least a dozen powders in a neat, easy to read chart. As soon as I get his permission, I will post the chart for all to enjoy.

Now, I'm off to the reloading bench, and I hope to post some results tomorrow evening.

Thanks everyone!

Good, glad it turned out well for you. I bet you can get some really good groups with them too. I'd have to check, but I think my first groups were less than an inch, and only got smaller. I've only loaded one box up, but I was really impressed with them. I just wish they were a little bit cheaper (like everything else in my life).

I know the feeling. I just purchased a 700 5r Milspec in .300 Winmag. I have been saving and searching for a year for this rifle. Now...if someone has advice on breaking-it to the wife...I'm all ears. It will arrive on Friday (if ya'll don't see any posts for a week or so, my eyes may be too swollen to see the keyboard).
