RWS 48 .177 caliber Annual Caliber Performance & Maintenance Check

This morning's airgun time revolved around pulling this classic RWS 48 out of the vault to give it a little love. This rifle is an older model, as evidence by the steel safety that rotates up and down extremely smoothly and the beautiful older well made and finished stock. I purchased it from an AGN member now several years ago.

It doesn't get shot very much, as evidenced by how clean the barrel was. Running two patches through it, one lubricated and one not, hardly any fouling was evident. I did fire two rounds of felt cleaning pellets through it, with two pellets double stacked for each firing cycle.

All of the scope and stock screws were firmly in place with no additional tightening needed.

I have had two different Vortek kits in this rifle over time. One was advertised as a 12 ft lb kit that I was getting right at 11.5 ft lbs out of with no adjustments. I didn't shoot it that way very long before purchasing a PG4 Steel HO kit and installing it. It came in shooting too hot, nearly 20 ft lbs, and I cut some coils off to get it to the power level you see today.

It is fitted with one of the oldest Hawke AirMax scopes I own, an 8-32x50, I own three of these, with the other two being 6-24x50, that have had literally thousands of rounds through them on both springers and pcps, holding their reticle positions perfectly, without any issues what so ever. The scope on this rifle is mounted on Sports Match vertically adjustable rings, with one rear recoil stop in in place. Never any issues.

This rifle is very smooth to cock and shoot and is one of the most "stable" springers in my collection. The core of the 10 shot groups as evidenced below, is very tight. For whatever reason, this was just one of those days with group one doubling in size as 1 shot out of 10 went wide of the group, as did three shots out of the 10 in group 2.

Like all of your rifles and mine, it is still fun to shoot. It is plenty accurate and powerful for a tree rats' demise.

Thanks for looking. I hope you enjoy seeing the stats.

Should be. Left rear of the receiver tube usually just above the stock. Sometimes obscured by the stock a little but there should be two numbers that are the month and year of manufacture. My 52 Luxus has 10 07 so October 2007. Yours sounds like a T01 trigger gun because of the steel safety so it will be older. It probably won’t have a trigger designation stamped anywhere because obviously “01” was the first. Is your receiver stamped “Model 48/52”? The older guns were stamped that way as I think a cost saving measure. The stock is making me wonder if that’s actually a Model 52. Same mechanics but 52 had the nicer checkered stock with raised cheek piece. Also longer, I think the LOP is 1” or more longer on the 52? I might have that info somewhere. Far as I know the 48 always had the smooth stock and no cheek piece. Don’t take that as gospel from me, I’m still learning. Might be able to find someone from whom we could take as gospel though!
 
I am glad. If you have any questions, just ask. It isn’t that I am so smart, just old….. There will be about thirty reviews in total once I get done.

Thanks.
And after the 30 are done, it will be time to start over again.

Still like to read your reviews. Just makes me want to come back to town and shoot them with you. Maybe in December.

Take care.
 
Your reviews are awesome. I still have a couple previous I need to finish. With your permission I’d like to copy a couple of your photos and post them next door. Some longtime Diana guys there that can verify but I’m pretty sure you have a Model 52. SteveP-52 here is pretty well-versed in Diana lore, if he sees this he can probably say for sure.

Mine is a 48 but I installed a 52 stock on it. Same basic rifle just different dresses.

True, but that extra 1” in stock length and LOP makes a difference in feel and most folks prefer one over the other. With the older guns lettered 48/52 I’m not sure there’s a way to tell how it was originally sold. Newer guns are different, mine has 52L on top of the tube.

Edit: Finally got a chance to post next door. Will let you know what they say.
