Beeman R1

You might want to consider combining your break in with velocity testing and pellet selection. The first step is to thoroughly clean the barrel to get rid of manufacturing crud or whatever. Just remember that it can take up to 50 shots to season a squeaky clean barrel and settle it in.

Pick your zero distance and set up a largish target. Pain paper with a central aiming point or multiple points works well. You are just trying to establish group size to get a rough idea of which pellets your rifle dislikes. Try to have a selection of good quality lead pellets - JSBs a H&N s are my favorites. Kodiak/Barracudas often work well in an R-1. Also, a longer range target will give you a better idea of how a pellet performs. Many pellets will group reasonably at 25 yds, but open up at longer ranges. If you have a chronograph, you can shoot through it and at your target at the same time.

Don't forget to put out a lot of fun targets (water filled cans, paintballs etc) at the same distance to break the boredom. Heck, put them out everywhere. By the end of the weekend you will have fulfilled your break in, begun informal testing, and have a really good feel for your rifle.

Turn the chore into a fun, data gathering exercise. And enjoy that fine rifle!
 
Oh and fine it is, hopefully get some pics up. Iv'e already shot it loose so have to wait to get home to make it right. Thanks for all your input. Oh and I settled in with the CP10.5s @ 150 rnds. You know I am shooting open @ 25yds and if I do my part will hit bottle cap 1out a3. For me thats pretty good. 1 more I had all the pels recomended by you fine Fella's.
 
 My R1 is in .20, but my R7 is .177. In all my .177's, and I have a few, the JSB 8.44 is always a good performer.

Why you want to put a thousand pellets through it "right away" is something up to you, but right from the start the JSB's will be accurate. I'm not sure if Weihrauch uses different springs fro each caliber, but I do know they have a "life expectancy". The R1 is a medium difficult spring to replace. Enjoy each shot, those rifles are very nice.

Here are the pics I have of my Beeman. As far as the 1000 shots, I'm hopefully going to get it to tame down a bit. It's a pretty harsh shot cycle.

JW652 gave some good pointers to which I would add, eliminate or reduce as many variables as possible from the start. Make sure all your stock screws are tight. Not he-man tight, just man-snug. You might remove the screws, degrease them and the female threads in the gun and reinstall them with thread locker (not the permanent type). Screws can shoot loose over the course of a thousand rounds and change your accuracy. Be very consistent with your hold, day in and day out when comparing pellet accuracy. R1's can be hold sensitive. It might take you some time to find the best hold, just be sure to use the same hold every time when doing comparisons. And Doc Beeman used to say the proper adjustment on the barrel pivot screw and nut is to tighten them so the barrel just barely stays in any position after cocking the gun. It shouldn't fall open or be too tight.

You've been given good recommendations for pellets. Favor medium to heavy pellets over lightweight pellets. Different head diameters will compound your search for the best pellet. Some of my HW's like 4.50's while my San Rafael .177 R1 likes 4.52's. I would start with 4.51 or 4.52 head diameters.

You have a beautiful gun there, enjoy it.
