I don't suppose they will have pistol powders and the more obscure Vit powders like N110 which I use for .357 mag. Basically I use N110, N140, N165 and sometimes 5 series. Thanks for the reminder.
Have a look on their website for powders they are likely to have.
They very kindly supplied me with N150 and N160 in 3.5kg tubs which they made up for me as they didnt have any "pre made" in stock.
I paid up front and collected at Bisley.
I also use N120 which they always seem to have.
They did say that they would make up 3.5kilo tubs of N500 series powders if I needed it.

Tony, thanks for the info. I did look at their site and was amazed at what they have on offer. I think its worth a trip to Glos. Colin

A nice load for 303 is 35 grains of Alliant Reloder 10 with a 170g bullet. Its economical too as you get 200x charges out of a 1lb tub.

In my experience the .303 is *very* forgiving as far as powder and bullet selection.

Given the .303's flexibility, it's reasonable to select for powder price or availability. Lately I've used BL-C2, which performs well in most of the rifle cartridges I load, is easily metered, burns cleanly, and is easily available to me. But I've used probably twenty different powders that performed just fine in the .303...
