Q: I have a 1890 winchester pump .22 the barrel shows .22 WRF .45gr bullet only. Will they work in my rifle? Thanks Dennis

Posted On: 2/3/14 By: Dennis

A: Hello Dennis, Unfortunately, the .22 Win Auto rounds can only be fired in a Winchester 1903 rifle and not your 1890 Winchester pump. You would need .22 WRF ammo for your rifle.

Fortunate find Review by Old Man
I was surfing Your Site and stumbled across this listing. I could not believe what I saw, I've had a 1903 for 25 years. I've been hoarding the last Two Boxes of original Ammo, affraid to use it up. Thanks to You My Kids can enjoy this wonderful Rifle as if it were a modern .22. Like the saying "They dont make em like that anymore" (2) Boxes of Ammo functioned as expected cycling with no issues, thanks for reminding Me I need to purchase more. (Posted on 2/13/14)
lucky to find this Review by pre64lover
I love to collect the old rifles and find it a challenge to hunt down the old ammo to make them bark again. I've only been able to find one box of this stuff until now. My old 1903 sends these babies down range with the accuracy that Winchester intended them to have. And at the price you charged, i was able to get enough to go hunting with it, as well as target shooting. Thanks for great service on an outstanding product. I'll be back for more. (Posted on 2/8/14)
Thanks to aquilla Review by Unkie
Fantastic load, not a single miss fire or eject problem, great 100 yard groups. (Posted on 2/7/14)
Lucky Gunnery save me enough to pay shipping and handling compared to the prices of another website. Thanks lucky Gunnery Review by larry
I found my Winchester in an old closet in a house I was tearing down. When I looked at the serial nos. it 03, 04, etc; I thought it was a new model automatic rifle that I was not familiar with. When I tried to put a 22 long in the chamber it would not eject. I took it to a gun smith to see if the eject mechanism was wore out. That is when he told me I had a 1903 Winchester Auto and it took a special shell and he didn't think they made them any more. I got on the internet and found two sites that sold rounds that I needed. The first one was priced higher than Lucky Gunnery. By ordering from Lucky Gunnery I save enough to Pay shipping and handling. Lucky Gunnery shipped quickly and delivered a quality product. Thanks Lucky Gunnery. Will recommend you any time. (Posted on 2/6/14)
So glad this ammo for the Winchester Model 03 Automatic Rifle is still available! Review by Honestbroker
I inherited this rifle from my Grand Mother - I am 70. She owned it as a teenager and it was handed over to my Mother who passed it on to me. Actually I bought it from my younger brother because he couldn't find any ammo for it and I wanted it as an heirloom. The rifle is in great shape with most of its bluing in very good condition and the wood stock as well. I have shot about 20 of these rounds and they work great great and, just like said in another comment, this rifle is very accurate with the ghost ring back sight. At 50 yards the front site covers the target and I get a close group just ot the right of the bulls eye. I have 2 fairly new .22s and this old Winchester is more accurate and, for some reason, it is more quiet. Very happy!

Great ammo Review by Jim
Burns clean, cycles perfect, very accurate. The 03 Winchester is a tack driver and Aguila ammo only helps. A rep from Aguila told me they are still producing this ammo with no immediate plans to stop, so please keep buying it and encouraging Aguila to continue manufacturing an excellent round for one of the best rimfire firearms ever made. Send them emails. (Posted on 12/13/13)
Dads 80th Birthday Present Review by Bell Family Unit
Thank you for this ammo. I gave it to my Dad on his 80th birthday, allowing him to once again shoot his 1st rifle, the Model 1903 Winchester Auto. He never thought he would get to shoot it again. We shot a box full and performace was excellent. Delivery was as promised. It was expensive, but the look on Dads face was priceless. Thanks. (Posted on 11/17/13)
