How well does the 45 colt work out in the 454 SRH as far as accuracy and the use of cast boolits. IMHO it is overkill to use a 454 for deer size game unless your concentrating on long range. I have a BH Bisley in 45 colt a ton of brass and cast boolits, but the SRH apeals to me more than the bis. Dont want to go to the expense of shooting 454 brass.
