Roasted barley (300 SRM) subsitute

[Blou04]

Hi, i'm planning to brew a scotch next month(8gal), i'd like to do that recipe : https://www.homebrewtalk.com/showthread.php?t=153797

My problem: i can't find 300 SRM roasted barley, only 1100-1400 ebc. I was thinking i could use half the roasted barley the recipe calls for, as what is carried is belgium is more roasted. I understand it's not the same flavor profile, how can i get the closest.
Also, i can't find special roast(50°L), can i substitute with some aroma malt( 100 ebc) or crystal (caramel 120 ebc).

I cry of all the conversion i got to do to keep using US recipes(F°, SRM, gal and oz to C°, ebc, L and grams).

Thank you

Yeah, i forgot to mention, i live in Belgium, so any US-based site is going to cost me more in shipping than malt. I can order from brouwland.com, homebrewshop.be and eventually maltmiller.co.uk

Light roasted barley is impossible to find around here, i was asking to substitute it.

Hum, I think you'd get a more British 'authentic' beer if you substituted the roast barley for a smaller amount of Patent Malt (for colour only), and the special roast for Amber Malt.

I hadn't realised how pale that American roast barley is! Falls just below Chocolate Malt. No wonder they use 10% in a stout!

So, something along the lines of:
81.5% Maris Otter(3.0srm)
5.8% Caramel 60L
5.8% Munich (9.0srm)
5.8% Amber malt (50 ebc =>25 srm)%that's what my HBS sells as amber malt
0.5% Black malt (1100-1400srm => 600-700 ebc)
0.5%Chocolate(900 ebc => 450 srm)
some malts are slightly different from the us version.
Would this be close enough from the original recipe. Thank for the advices

From my personal point of view that looks better than the original, plus it uses local ingredients (well, I assume the Amber malt is Crisp or other British malt)

The black malt is from Thomas Fawcett but i think the amber malt is from brewferm (belgian maltster).

I'd trust Brewferm to know what Amber malt is
