Hi Tim
The site sponsor J S Ramsbottom has the RWS hollow point in .25,they are 25 grain and 6.35 but I found them a easy fit in my pre 2013 Lightning. I got my H/P for £2 a tin on a special deal they had going at the time.They are doing them for £3.79 a tin at the moment.
May be worth a try at that price.
Les..
