OK. I've had a chance to try out my new Broadway SC and the first time out I was impressed. Top gun for the day shot mid 80s and I shot high 60s. I wanted to improve on that the second time out which was the holiday Monday just passed. I was a little disappointed and only shot mid 50s but high gun for the day was only 71 due to a revamp of some of the stations. I think the stations are going to be changed again to make it easier and fun again.
As far as handling goes it feels a little longish shouldering so I may take the black spacer out, but am not sure about that because once the gun is mounted it feels comfortable. I may just get used to it.
I like the kick-eez pad and it seems to allow me to mount the gun higher than the trap pad. The beads line up in a nice figure 8. With the trap pad I see more rib between front and rear beads. It makes for flatter shooting it seems.
For me it points nicely and when swinging at fast moving angling or side ways targets it is smooth with enough weight for a decent follow through.
I put a leather pad on the inside of my shooting vest after the first shoot with it and it feels better now. My new Browning vest has less padding there than my previous one. I may buy the Browning reactor pad to put in but for now the leather is OK. So yes it is not as soft shooting as a semi but I don't mind it. I am using 1 oz of shot in front of approx. 18 g. of Promo. I use WW Super Handicap for trap and the load is much milder than that!
planemaker, as far as the Broadway rib goes I don't find it in the least distracting. Once a target is called I really don't see it or the beads. A friend of mine who I shoot with regularly does find it distracting and would never have one. He is also a Browning fan but likes the narrower rib. Personally I like the look of the wide rib and it makes the gun seem solid and better contoured than a thin rib.
You may not find a Broadway with RK because they weren't made until 1961 and as far as I know all had the square knob.
The long tang was change to short in 1967 I believe so you'll have to find a 1961-66 vintage.
I am shooting a 1961 for trap and like it very much. Shot a 46 16 and a 43 27 today. Not great but I've shot worse too!
My 1967 Broadway SC has a 30m inch barrel and after shooting it I would not hesitate to make a 32 barreled one into SC either. The 30s do swing fast but a 32 would be suitable I'm sure.
The Broadways all seem to have a high comb. I know I wouldn't want to adjust them higher. Maybe lower if anything.
Extended chokes are definitely the way to go but you may be limited to Briley series 1 chokes because of the thin space between the upper and lower barrels of the Broaways. I didn't do as much research as I possibly should have but am satisfied with the Briley tubes I have. I bought a speed wrench from Briley so changing chokes is quite simple provided you don't misplace the tool.
My Broadways are all Lightning models and I too love the old RKLT Supers. Everyone I've ever picked up seems to melt right into your shoulder.
Well that's all for now and if you go through with your project planemaker I think you will be satisfied.
